UMD22N-TP

Overview

The UMD22N-TP is a dual digital transistor from Micro Commercial Components, integrating one NPN and one PNP pre-biased transistor within a single SOT-363 (SC-88) surface-mount package. It features a supply voltage of 50V for the NPN section and -50V for the PNP section, with continuous collector currents rated at 100mA and -100mA respectively. The device includes typical internal base resistors of 4.7kΩ and emitter-base resistors of 47kΩ. Designed for low power dissipation of 150mW, it operates across a temperature range of -55°C to +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors in a compact footprint
• Includes built-in biasing resistors to simplify circuit design
• Supports high-temperature operation up to 150°C

Applications

• Differential amplifier circuits
• High-frequency crystal oscillator drivers
• General-purpose switching applications

Procurement Notes

Verify component authenticity through authorized MCC distributors or certified suppliers. Request original datasheets and material compliance documentation prior to procurement. Ensure storage conditions align with manufacturer specifications to maintain device integrity during handling and assembly processes.

Selection Notes

Select this component when space-constrained designs require both NPN and PNP switching capabilities. The integrated resistor network reduces external component count compared to discrete solutions. Confirm that the 150mW power dissipation rating meets thermal requirements for the specific application environment.

Part Context

This part belongs to the UMD series of complex transistors manufactured by Micro Commercial Components. It serves as a surface-mount alternative to discrete transistor pairs, offering standardized pin configurations compatible with common PCB footprints like SC-88. The TP suffix typically indicates tape-and-reel packaging for automated assembly.

Replacement Considerations

The UMD22NFHATR from Rohm Semiconductor is a documented equivalent featuring identical NPN/PNP configuration, 50V ratings, and 4.7kΩ/47kΩ resistor values within the same UMT6/SOT-363 package.
