STMICROELECTRONICS NPN Darlington Transistor Array 50V 500mA 1000hFE SOIC

This STMICROELECTRONICS NPN Darlington Transistor Array is a high-voltage, high-current device featuring seven open-collector Darlington pairs with common emitters. Designed to simplify board layout, the inputs are pinned opposite the outputs, offering convenience and efficiency during installation.

Each channel is rated at 500mA and can withstand peak currents of up to 600mA. For added versatility, the outputs can be paralleled to achieve higher current capabilities. Integrated suppression diodes make this array highly suitable for driving inductive loads safely.

The device boasts TTL, CMOS, PMOS, and DTL compatible inputs, ensuring broad compatibility across various logic families. With a typical collector-emitter saturation voltage of 0.9V and a rapid typical turn-on and turn-off delay time of 1µs, it provides reliable and swift switching performance.
