The PUMF12 is a combination of Philips' PNP general purpose power transistor and NPN diode. It has 100mA collector current, 50V collector-emitter voltage, 300mW total power dissipation, and SOT363 package. It can replace two SOT323 packaged devices on the same PCB area.
The document describes the Philips PUMF12 discrete semiconductor device, which integrates two transistors into a single SOT363 (SC-88) plastic package. This design replaces two separate SOT323 devices on the same PCB area to reduce pick and place costs while maintaining functionality for power management switches in portable equipment like cellular phones and CD players.
The datasheet details electrical characteristics, limiting values, and thermal properties for both the PNP (TR1) and NPN (TR2) transistors. It includes a typical application circuit diagram for power management and provides package outline dimensions.
| Collector current (DC) | -100 mA |
|---|---|
| Total power dissipation | 300 mW |
| Package type | SOT363 (SC-88) |
| Collector-emitter voltage (TR1 PNP) | -50 V |
It is used as a power management switch for portable equipment, such as cellular phones and CD players, or as a switch for regulators.
The maximum DC collector current is 100 mA, with a peak collector current of 200 mA.
