NPN general-purpose transistor supports switching and amplification in a small SOT23 surface-mounted plastic package. The device is rated for 45 V collector-emitter voltage and 500 mA continuous collector current, with 1 A peak collector current for short pulses. The -40 gain selection provides 250 to 600 DC current gain at 100 mA and 1 V. Operation is specified from -65 °C to 150 °C ambient temperature with a 150 °C maximum junction temperature.
