UNR9215G0L

Overview

The UNR9215G0L is a Silicon NPN epitaxial planar transistor with built-in resistors, designed for digital circuits. It features an SS-Mini3-F3 package with three pins: Base (Pin 1), Emitter (Pin 2), and Collector (Pin 3). The device has a maximum collector current of 100 mA and a total power dissipation of 125 mW at 25°C. Absolute maximum ratings include a collector-base voltage of 50 V and a collector-emitter voltage of 50 V. The junction temperature range is -55 to +125 °C. For the UNR9215G variant, the internal configuration includes a single base resistor (R1) of 10 kΩ with no emitter resistor (R2). The forward current transfer ratio (hFE) ranges from 160 to 460 at VCE = 10 V and IC = 5 mA.

Feature Summary

• Integrates bias resistors directly into the transistor structure to reduce component count and board space.
• Utilizes an SS-Mini type package suitable for automatic insertion via tape packing.
• Complies with the RoHS Directive (EU 2002/95/EC).

Applications

• Digital circuit switching applications
• Equipment downsizing through part reduction

Procurement Notes

Verify the specific lifecycle status of the UNR9215G0L before procurement, as the datasheet indicates that the UNR921xG series may include products in maintenance or discontinued stages. Confirm availability and latest specifications directly with Panasonic Industry sales representatives, as product information can be modified or become unavailable due to specification changes or manufacturing suspensions.

Selection Notes

Select the UNR9215G0L when a fixed 10 kΩ base resistor is required without an emitter resistor. Ensure the application operates within the 100 mA collector current limit and 125 mW power dissipation constraints. Verify that the 50 V voltage rating meets the circuit requirements. Consider the hFE range of 160 to 460 for gain stability in digital switching designs.
