UNR5212G0L

Overview

The UNR5212G0L is a Silicon NPN epitaxial planar transistor with built-in bias resistors, designed for digital circuits. It features an SMini3-F2 surface-mount package with three pins: Base (Pin 1), Emitter (Pin 2), and Collector (Pin 3). The device has a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. Total power dissipation is limited to 150 mW at 25°C ambient temperature. The internal configuration includes two resistors, R1 and R2, both rated at 22 kΩ. The forward current transfer ratio (hFE) has a minimum value of 60 at IC = 5 mA and VCE = 10 V. The transition frequency is specified at 150 MHz.

Feature Summary

• Integrates dual bias resistors within the transistor package to reduce component count and board space.
• Utilizes the compact SMini3-F2 surface-mount form factor suitable for automated insertion via tape packing.
• Constructed using silicon NPN epitaxial planar technology optimized for digital switching applications.

Applications

• Digital logic interface circuits
• General-purpose switching in electronic equipment
• Office automation and communications devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm resistor values and packaging type. Confirm compliance with RoHS Directive (EU 2002/95/EC) requirements for the intended market. Check the latest product lifecycle status on the Panasonic semiconductor website as this series may be subject to maintenance or discontinuation phases.

Selection Notes

Select this component when a single NPN transistor with two specific bias resistors is required to simplify circuit design. Ensure the 22 kΩ resistor values match the base drive requirements. Verify that the 50 V voltage rating and 100 mA current capacity exceed the maximum operating conditions of the target application.
