It integrates a 22 kΩ base resistor and a 47 kΩ emitter-base resistor, reducing external component count in switching and driver stages. The 200 MHz transition frequency suits it for low-frequency switching and signal conditioning in automotive modules such as ECU outputs, relay drivers, and sensor interfaces.
PG-SOT23 package — hand-solderable
The three-pin layout is standard for small-signal transistors, so PCB footprints are widely available in EDA libraries. Maximum power dissipation is 200 mW, typical for this package size — keep the junction temperature in check if driving near the 100 mA limit continuously.
AEC-Q101 — built for the engine bay
It is rated for the under-hood and chassis-domain environments where commercial-grade parts would fail. The 100 nA maximum collector cutoff current (ICBO) ensures low leakage at elevated temperatures, a critical parameter for automotive sensor inputs and wake-up circuits.
