UNR32A5G0L

Overview

The Panasonic UNR32A5G0L is a silicon NPN epitaxial planar transistor with a built-in resistor, designed for digital circuits. It features an absolute maximum collector-emitter voltage of 50 V and a collector current rating of 80 mA. The device dissipates up to 100 mW of power at 25°C ambient temperature. Key electrical characteristics include a forward current transfer ratio (hFE) ranging from 160 to 460 at 5 mA, and a transition frequency of 150 MHz. The internal base resistor (R1) has a nominal value of 10 kΩ with a ±30% tolerance. The component is housed in the SSSMini3-F2 surface-mount package.

Feature Summary

• Suitable for high-density mounting and downsizing of equipment
• Contributes to low power consumption

Applications

• General electronic equipment such as office equipment
• Communications equipment
• Measuring instruments
• Household appliances

Procurement Notes

Verify the specific lifecycle status before procurement, as the datasheet indicates maintenance or discontinuation stages. Confirm that the application remains within standard general electronic equipment parameters, as specialized uses require direct consultation with sales staff. Ensure compliance with RoHS Directive standards during integration.

Selection Notes

Select this component for applications requiring compact digital switching with integrated biasing. The 10 kΩ internal resistor simplifies circuit design by reducing external component count. Verify that the required collector current does not exceed 80 mA and that the operating environment stays within the specified junction temperature limits.

Part Context

This part belongs to the UNR32A series of transistors with built-in resistors manufactured by Panasonic Semiconductor. These components are engineered to facilitate the miniaturization of digital circuits. The UNR32A5G variant specifically provides NPN configuration with defined hFE ranges suitable for standard logic interfacing tasks.

Replacement Considerations

Consult Panasonic sales for updated alternatives if the current stock is discontinued. Cross-reference with other UNR32 series parts only if pinout and electrical ratings match exactly. Do not substitute without verifying package compatibility and thermal performance.
