UMB9N-TP

Overview

The UMB9N-TP is a dual pre-biased PNP digital transistor array manufactured by Micro Commercial Components. It integrates two PNP transistors with built-in base resistors into a single surface-mount package, specifically the SOT-363 (SC-88) configuration. The device features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Each internal transistor includes a typical base resistor value of 10 kOhms, facilitating direct interface with logic outputs. The unit operates within a temperature range of -55°C to +150°C and dissipates up to 150mW of power.

Feature Summary

• Dual PNP transistor configuration with integrated base biasing resistors
• Compact SOT-363 surface-mount packaging for space-constrained designs
• High transition frequency capability suitable for RF and switching applications

Applications

• Digital logic level shifting circuits
• Switching applications in portable electronic devices
• Driver stages for low-power loads requiring pre-biased control

Procurement Notes

Verify the specific suffix TP indicates tape and reel packaging when sourcing. Confirm the manufacturer is Micro Commercial Components to ensure component authenticity. Check datasheet revisions for any updates to electrical characteristics or pinout definitions before finalizing procurement specifications.

Selection Notes

Select this component when a dual PNP solution with integrated biasing is required to reduce external component count. Ensure the 50V breakdown voltage and 100mA current rating exceed circuit requirements. Consider the SOT-363 footprint constraints during PCB layout design to match the SC-88 package dimensions.

Part Context

This part belongs to the UMB series of digital transistors from MCC. It serves as a compact alternative to discrete transistor pairs, simplifying assembly. The UMB9N-TP variant specifically denotes the dual PNP configuration with standard biasing values, distinguishing it from other polarity or resistance variants in the family.

Replacement Considerations

Direct substitutes include other dual PNP pre-biased transistors in SOT-363 packages from manufacturers like Onsemi or Diodes Inc., provided they match the 50V Vceo, 100mA Ic, and 10k Ohm base resistor specifications.
