Talking complimentary pair

Good Afternoon:

I'm currently looking to find a complimentary transistor pair that is relatively low in cost ie <= $3.50 in quantities of ten or less and matches or exceeds the following parameters.

Pdmax >= 100 watts
VCE >= 100 volts
Ic > 15 amps
Beta >10

Could anyone please point me in the right direction...

Default Matched Pair

Toshiba has some very good ones, they are PNP 2SA1943 and NPN 2SC5200. These are high speed devices rated at
230 V with a colector current of 15 amps, hFE 55 to 160 and the
fT is 30Mhz.

These devices replaced Motorola 2SA1302 and 2SC3281

Good Luck
Jim W.

I think you mean complementary pair. A complimentary thing is given away. On the other hand, perhaps that was what you meant...
The loudspeaker: The only commercial Hi-Fi item where a disproportionate part of the budget isn't spent on the box. And the one where it would make a difference...

complimentary: expressing or containing a compliment

Doesn't every designer want his creations to
say nice things about him? ;-)
