2n3055hv what is this?

Easyamp · 18th May 2004, 02:46 PM

I found some 2n3055hv's for sale at www.allelectronics.com and assumed the hv at the end means high voltage but haven't been able to find a data sheet or a manufacturer.

Does anyone no the story on this?

I did find a this 2N3055HV.pdf but I don't know who kestparts is so?

A 2n3055 with a vceo of 140v and still only a $1.00 I hope this true.

Hi Easy

In the data sheet they don't tell the Max. Power Dissipation...strange

In the normal 2n3055 is 115 W.

hey Tube_Dude,

I'm not sure where they got the information from, if it was from a real datasheet I would think the power dissipation would of been listed.

I can't believe I've never heard of this 2n3055hv chip so I'm a little skeptical of it, which is why I posted to see if someone else has used it or even seen it maybe.

I guess I'll be the guinie pig and buy some, check'em out.

Imo mje3055, tip3055, and 2n3055 usefulness is limited by it's low vceo (60V), for af amplifiers use anyway. So a 2n3055 with a vceo 140 is much better and for the same price.

I'd really like to find a real datasheet.

Cheers,

Hi Easyamp

But certainly you need a complementary pair...have they a MJ2955 HV ??

Cheers

2N3055HV = 15a, 120v, 90w

This may help

CDIL 2N3055HV

Perfect, thanx for help.

2N3055HV,

maybe HV stands for a High Voltage version by some odd manufacturer(KEST?), just a wild guess!

Tube_Dude · 18th May 2004, 04:44 PM

We began with vceo of 140 volts...after Bill put it in 120 volts and now in the data sheet given by mcp is 100 volts...

Somebody is stealing volts ...

We will end up with the regular 60 volts vceo..

"But certainly you need a complementary pair...have they a MJ2955 HV ??"

A 120V 3055/2955 is called a MJ15015/16, Motorola shows all four on one data sheet. Carver used these in the M400T and Crown in the Macrotech 600.

My guess is the 3055HV is actually a 2N3442

Motorola/ON Semiconductor prices went up again, 18% in the last couple of months.
