Hi Again
The cost of these Lateral MOSFETs are much cheaper than any other brands.
$6.00US each for the N Channel and P-Channel
In lots of 1-10 |
|
|
| The Saint |
| Here is some basic data for the N-channel Device |
|
|

| And Some Basic data for the P-Channel Device. |

Thank You, Thank You :angel: |

I don't want to make this achievement any smaller than it is.......but-if you achieve same with little tiny signal J-fets.......I'll personally swim big splash to kiss ya in bottom of your back
:clown:
no kidding.......I think that's great !
btw-isn't 1C/W die-case little on high side ? |
|
|
| The Saint |
Yes I agree the 1C/W die-case does seem high.
I think this is a typo error.
The data sheet was prepared by office staff in the UK.
I will get them to change it to the correct value. |

These New MOSFETs have been designed to be a broadspectrum
replacement for all of the available Lateral MOSFETs on the market today and to be supplied at much cheaper prices than you would normally expect to pay.
They have also been designed to handle more power than the current range of Lateral MOSFETs available on the market place.
The Single die versions are rated at 10 amps
One of the added features of these Lateral MOSFETs is the placement of an internal 15 Ohm Gate resistor.
Which is etched into the silicon die, right on the GATE.
This aids in improved stability of the device which is not found in any other lateral mosfet. |

| Twenty years ago I had read in some Hitachi's papers, that internal resistance of gate is ( as I remember ) about 30 Ohms, 'cos aluminium traces on die are very thin...so nothing new under the Sun, Anthony....:cool: |
|
|
| The Saint |
That my well be so but we have added an additional gate resistor
into the die its self and increased the channel width for increased current capability. |

Hi Anthony,
Can I Use Lateral Mosfet like 2sk1058/2sj162 instead of Hexfet irfp240/irfp9240 in your av400/av800 design?
rlg;) |

| The Saint |
Hi Rig
Yes you could use Lateral MOSFETs in the AV400 and AV800 designs, but not with the existing PCBs.
The pinouts on the Laterals are swapped between Drain and Source.
However I will be releasing 4 x new designs based on my NX150
that are going to replace the AV400 and AV800 amplifier modules.
They will be the NX400 Synergy, NX500NL and NX800NL/NX1000NL.
All of these designs use lateral mosfets.
The NX400 uses Dual die N and P mosfets, while the NX500NL and NX800NL/NX1000NL are all N-channel designs. |

Hi Paulb
Yes they will, A drop in replacement :D |

Hello Anthony,
how we can order these parts in EU.
I don't see them available on www.class-d.com site.

Hi Tibi
The new laterals will be released very soon.
In the last number of months since their announcement we have been organising the final design specs and where they will be
manufactured.
This has finally been sorted out and I have just received a number of the first production samples for final testing.
I am happy to say they have passed with flying colours.
In fact they have proven to be much more stable and have a
higher power capablity than all of the other laterals I have used before.
This is due to a number of changes that were done to the die mask before the silicon wafer was grown.
They should be available from the www.class-d.com site in the next month or so and will also be available from www.aussieamplifiers.com at about the same time. |

Thanks Anthony !
Please inform DIY community (trough this forum) as soon these will be available.
I'm eager to test them. :yummy:

I am newer in here ,who can tell me what's mean of this phrase
Lateral Power Audio MOSFET's ? |

Hi i'm new a member, just reading about these replacements
sounds interesting. mickb. |
|
|
| mlloyd1 |
anthony:
when will more detailed datasheets be available?
i'm curious about transconductance curves compared to the old hitachi parts.
thanks,
mlloyd1 |
|
|
| The Saint |
Hi Mlloyd1, mikeb
The data for these devices will delayed till later this year.
The Transconductance of these device is the same as hitachi and semelab devices.
The main difference with these devices is improved stablity with the single die N & P devices.
Also they will be quite a bit cheaper than other manufacturers. |

| janusz |
Great news Anthony. How well these new N and P channel devices match? Same as old Hitachi or some improvement here as well? I believe I'll buy a number of them anyway. Pity that laterals have different pin order than other mosfets such as irfp240.
cheers, |

Now how about some tinnies to replace the J56 and K176s
used in so many Australasian amps.....

Hi Mobyd
There is plans to release these mosfets in the classic TO-3 style
package.
At this stage I am unable to tell you when that might be. |

Hello,
great news this release. What is the capacitance of the devices? |
|
|
| The Saint |
Hi Megajocke and SunRa
SunRa
The input capacitance for the single die N channel is 550pf
The single die P channel is 950pf
The dual die versions are double that amounts.
Megajocke
Yes these devices are self regulating in just the same way as the Hitachi devices, They are both Lateral MOSFET's. |

Hi Anthony!
I think you might have misunderstood me, beacause I wasn't referring to the bias current stability, which is excellent for laterals at 100mA. I was referring to the not-so-obvious way they protect themselves from overtemperature during for example a short on the output of the amp. They start to draw gate current when the chip reaches about 200 degrees celsius and if the gate current exceeds about 8mA some kind of thyristor structure is triggered, shorting the gate to source.
Do you know what it is in the transistor that causes this? I was wondering if your new devices exhibit the same behaviour. |
