285 V NPN in a TO-251-3 leaded package
The TTC008(Q) is a 285 V, 1.5 A NPN transistor in a TO-251-3 Short Leads (IPak, TO-251AA) through-hole package, designated PW-MOLD2 by Toshiba. It is rated for 1.1 W maximum power dissipation at a junction temperature up to 150 °C.
Gain and saturation at low drive
Vce(sat) is specified at 1 V max with Ib = 62.5 mA and Ic = 500 mA, meaning it can saturate hard enough to keep conduction losses under 0.5 W at that point. Collector cutoff current (ICBO) is 10 µA max — leakage is low enough that it will not pull a load resistor in a high-impedance off-state circuit.
