NPN pre-biased transistor with integrated 47 kOhm resistors
It integrates two 47 kOhm resistors — R1 between base and the bias node, R2 between base and emitter — which eliminate the need for external bias components in switching and driver circuits. The 100 MHz transition frequency supports switching in relay coils, solenoid drivers, and logic-level translation up to several MHz.
NRND — last-time-buy window
It is not a candidate for new BOMs; existing designs should plan for a last-time-buy or identify a pin-compatible replacement before the supply window closes.
Saturation voltage and gain at low collector current
Maximum Vce saturation is 300 mV at a base current of 500 µA and collector current of 10 mA — a typical drive condition for a small relay or LED string.
