UP0331200L

Overview

The Panasonic UP03312L is a composite transistor featuring an NPN epitaxial planar type (Tr1) and a PNP epitaxial planar type (Tr2) integrated into a single SSMini5-F2 package. It operates with collector-emitter voltages of ±50 V and continuous collector currents of ±100 mA, dissipating up to 125 mW total power at 25°C. The device includes built-in base resistors (R1: 22 kΩ nominal, R2: 22 kΩ nominal) for digital circuit applications. Transition frequencies are specified at 80 MHz for the NPN element and 150 MHz for the PNP element.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in base resistors into a compact surface-mount package.
• Reduces mounting area and assembly costs by consolidating two discrete elements into one component.

Applications

• Digital logic circuits
• General electronic equipment
• Office equipment
• Communications equipment

Procurement Notes

Verify current lifecycle status directly with Panasonic or authorized distributors, as maintenance/discontinued information requires checking official channels. Confirm RoHS compliance documentation matches specific manufacturing dates. Ensure design reviews account for absolute maximum ratings regarding transient states during power-on or mode-switching to prevent device failure.

Selection Notes

Select this component when space constraints require combining complementary switching functions. Verify that the 22 kΩ internal base resistance aligns with the driving source impedance and required input voltage levels. Consider the 125 mW total power dissipation limit and derating requirements for ambient temperatures exceeding 25°C.
