UNR5215G0L

Overview

The UNR5215G0L is a Silicon NPN epitaxial planar transistor with built-in bias resistors, designed for digital circuits. It features an SMini3-F2 package with pin configuration of Base (1), Emitter (2), and Collector (3). Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a collector current (IC) of 100 mA, and total power dissipation (PT) of 150 mW at 25°C. The transition frequency (fT) is 150 MHz. For the UNR5215G variant, the internal base resistor (R1) is 10 kΩ. The forward current transfer ratio (hFE) ranges from 160 to 460.

Feature Summary

• Integrates a single NPN transistor with a built-in 10 kΩ base resistor to reduce component count and board space.
• Utilizes the compact SMini3-F2 surface-mount package suitable for automatic insertion via tape or magazine packing.

Applications

• Digital logic interface circuits
• Switching applications in general electronic equipment
• Driver stages for low-current loads

Procurement Notes

Verify the specific lifecycle status directly with Panasonic Industry, as the datasheet indicates maintenance or discontinuation phases for this series. Confirm RoHS compliance (EU 2002/95/EC) and ensure the ordering suffix matches the required packaging format. Cross-reference the marking symbol '8E' to validate the exact resistance configuration during procurement.

Selection Notes

Select the UNR5215G0L when a fixed 10 kΩ base drive resistor is required for NPN switching. Ensure the application operates within the 50 V collector-emitter voltage limit and 100 mA maximum collector current. Consider the 150 mW power dissipation constraint at ambient temperatures up to 25°C. Verify that the hFE range of 160 to 460 meets the circuit's gain requirements.
