UP04312G0L

Overview

The Panasonic UP04312G is a composite transistor array housed in an SSMini6-F2 surface-mount package. It integrates one silicon NPN epitaxial planar transistor (Tr1) and one silicon PNP epitaxial planar transistor (Tr2) into a single component. The device features built-in base resistors, with Tr1 utilizing a 22 kΩ input resistance (R1). Maximum ratings include a collector-emitter voltage of 50 V for both transistors, a maximum collector current of 100 mA, and a total power dissipation of 125 mW at 25°C ambient temperature. Transition frequencies are specified at 150 MHz for the NPN element and 80 MHz for the PNP element.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in resistors within a single compact package to reduce mounting area and assembly costs.

Applications

• Switching circuits
• Digital circuits

Procurement Notes

Verify the current product lifecycle status directly with Panasonic Industry before procurement. The datasheet indicates this component falls under maintenance or discontinued categories. Confirm availability through official distribution channels and ensure compliance with RoHS Directive requirements during acquisition.

Selection Notes

Select this component when space-constrained designs require paired switching elements with fixed biasing. Ensure the required transition frequency meets the 150 MHz NPN and 80 MHz PNP specifications. Verify that the 22 kΩ internal resistor value aligns with the target logic interface levels and drive currents.

Part Context

This part belongs to the UP043 series of composite transistors manufactured by Panasonic Industry. It serves as a discrete semiconductor solution for general-purpose electronic equipment, office appliances, and communication devices where standard reliability is sufficient.

Replacement Considerations

Consult the manufacturer's official replacement list for verified substitutes. Cross-referencing requires matching the SSMini6-F2 package, 50V rating, and integrated resistor values.
