UNR32A4G0L

Overview

The Panasonic UNR32A4G0L is a silicon NPN epitaxial planar pre-biased transistor designed for digital circuits. It integrates base resistor R1 (10 kΩ) and emitter-base resistor R2 (47 kΩ) within an SSSMini3-F2 package. Key electrical ratings include a collector-emitter voltage of 50 V, maximum collector current of 80 mA, and total power dissipation of 100 mW at 25°C. The device features a transition frequency of 150 MHz and a DC current gain (hFE) of 80 at IC = 5 mA. Saturation voltage is specified as 0.25 V at IC = 10 mA.

Feature Summary

• Integrates internal biasing resistors to simplify circuit design and reduce component count.
• Optimized for high-density mounting and equipment downsizing in surface mount applications.
• Designed to contribute to low power consumption in digital logic interfaces.

Applications

• General-purpose digital circuit interfacing
• Logic level conversion between microcontrollers and peripheral devices
• Switching applications in office and communications equipment

Procurement Notes

Verify the specific suffix 'G0L' against the manufacturer's official documentation to confirm exact packaging and lifecycle status. The datasheet indicates this product falls under maintenance or discontinued categories; consult the latest Panasonic Industry semiconductor catalog for current availability and obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN pre-biased transistor with 10 kΩ base resistance is required. Ensure the application operates within the 50 V collector-emitter limit and 80 mA current constraint. Verify that the SSSMini3-F2 footprint matches the PCB layout requirements and that the 100 mW power dissipation rating accommodates the thermal environment.

Part Context

The UNR32A4G0L belongs to the Panasonic UNR series of transistors with built-in resistors. This series utilizes silicon NPN epitaxial planar technology specifically engineered for digital switching applications. The part is housed in the SSSMini3-F2 package, which supports automated surface-mount assembly processes for consumer electronics and industrial control hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires matching the 50V/80mA rating, 10kΩ/47kΩ resistor values, and SSSMini3-F2 package dimensions using independent distributor databases.
