High-voltage silicon NPN transistor is rated for 250 V collector-emitter sustaining voltage and 1.0 A continuous collector current. The device dissipates up to 1.0 W at 25 °C ambient or 5.0 W at 25 °C case temperature with operation from -65 °C to 200 °C. It uses a TO-39 metal-can package and provides 40 to 160 DC current gain at 20 mA with 10 V collector-emitter voltage.
