Question MJ15026 and MJ15027

MJ15026 and MJ15027

Hi!

Looking to the specs of the MJ15026 and MJ15027, 200V, 16A, 250W, I'm wondering if they are suitable for audio applications.

Any comments?

Thanks in advance

Pedro Martins

I have 6 of each.

They are sold here in Portugal. The price is 3,50 the MJ15026 and 4,10 the MJ15027.

These appear to be discontinued devices, but my older data book lists them. They're pretty robust and have a Ft of 15 MHz.

My most current databook suggests MJ15024/25 as substitutes.

Well, thanks for the information.

By the way, they have '96 in the case. 1996, maybe

As I have some of that, I'm going to try.

I am new to this page, but IMHO, I would try the MJL1302A (PNP) and the MJL 3281A (NPN). They are from ON Semiconductor (used to be Motorola). These units sport the following characteristics:


The MJL3281A and MJL1302A are PowerBase power transistors
for high power audio, disk head positioners and other linear
applications.

15 AMPERE COMPLEMENTARY SILICON POWER TRANSISTORS
Vce = 200 VOLTS
Pdiss = 200 WATTS

Designed for 100 W Audio Frequency

Gain Complementary:
Gain Linearity from 100 mA to 7 A
High Gain 60 to 175
hFE = 45 (Min) @ IC = 8 A

Low Harmonic Distortion

High Safe Operation Area 1 A/100 V @ 1 Second

High fT 30 MHz Typical

I especially like the 30MHz gain-bandwidth figure!

These units are used in some of the better high-end amplifiers.
try www.onsemi.com and go thru the pages to the Bipolar Power section. Best of luck!
