NP043A300A

Overview

The Panasonic NP043A3 is a composite transistor featuring an NPN epitaxial planar type (Tr1) and a PNP epitaxial planar type (Tr2) integrated into a single SSSMini6-F1 package. It includes built-in base resistors with a nominal value of 47 kΩ for each element. The device supports a maximum collector current of ±80 mA, a total power dissipation of 125 mW, and operates within a junction temperature range of -55°C to +125°C.

Feature Summary

• Dual-element integration combining separate NPN and PNP transistors in one compact package
• Built-in base resistors designed for direct digital circuit interfacing
• Ultra-thin profile suitable for space-constrained equipment designs

Applications

• Digital logic interface circuits
• Switching applications requiring complementary transistor pairs
• General-purpose electronic equipment

Procurement Notes

Verify the current lifecycle status directly with Panasonic or authorized distributors, as the documentation indicates maintenance or discontinuation planning. Confirm availability of the specific SSSMini6-F1 package configuration before finalizing design-in decisions.

Selection Notes

Select this component when a matched NPN/PNP pair with fixed biasing is required. Ensure the design accommodates the 47 kΩ internal resistance values and verify that the 125 mW total power dissipation limit meets the thermal requirements of the target application environment.

Part Context

This part belongs to the series of composite transistors designed for digital circuits. It serves as a compact alternative to discrete transistor arrangements, reducing mounting area and assembly costs while maintaining standard electrical characteristics for general-purpose switching tasks.

Replacement Considerations

Consult official Panasonic resources for verified substitute part numbers. Cross-referencing with other manufacturers requires careful validation of pinout compatibility, resistor values, and absolute maximum ratings.
