Product details

45 V, 500 mA NPN in SOT-23-3 — general-purpose switching and amplification

These ratings suit it for medium-current switching, relay and solenoid drivers, and small-signal amplification up to VHF frequencies. The 500 mW power dissipation limit and 150°C junction temperature define the thermal budget in compact layouts.

Saturation voltage and gain — what drives the switching decision

Vce saturation is specified at 700 mV maximum with a 50 mA base drive and 500 mA collector current.

SOT-23-3 footprint — rework-friendly and widely stocked

The SOT-23-3 package is one of the most common three-lead surface-mount footprints. It reflows cleanly with a standard lead-free profile and is easy to hand-solder or hot-air rework without lifting pads.
