Power Transistors for SSTCs



Original poster: "S & J Young by way of Terry Fritz <twftesla-at-qwest-dot-net>" <youngs-at-konnections-dot-net>

To SSTC experimenters,

Fairchild Semiconductor just announced some new transistors which should be
useful for SSTCs, flyback drivers, etc.  I quote the announcement from EE
Times:  Fairchild Semiconductor's next generation of horizontal deflection
transistor products in ther FJA and FJL lines are bipolar-junction types
that boast high-voltage capability and fast switching.  The deflection
transistors are said to be preferable to insulated-gate bipolar transistors
because of their low cost and faster turnoff switching without a tailing
characteristic.  The devices meet the needs of color monitors up to a
switching frequency of 130 kHz in a range of current ratings (10 to 25 A for
1,500 V devices, 20 A for 1,700 V devices).  Prices range from 65 cents to
$1.60 in 1,000 piece quantities."

Looks like good inexpensive devices as long as your coil resonates at 130
kHz or lower.
