UNR221400L

Overview

The Panasonic UNR2214 is a Silicon NPN epitaxial planar transistor with built-in resistors, designed for digital circuits. It features a Mini3-G1 (SC-59) package. The internal configuration includes a base resistor R1 of 10 kΩ and a collector resistor R2 of 47 kΩ. Absolute maximum ratings at 25°C include a collector-emitter voltage of 50 V, a collector current of 100 mA, and a total power dissipation of 200 mW. The junction temperature limit is 150°C, with a storage temperature range from -55°C to +150°C.

Feature Summary

• Integrates an NPN transistor with two specific biasing resistors to reduce component count and board space.
• Utilizes a compact Mini3-G1 surface-mount package suitable for automated assembly processes.

Applications

• Digital logic interface circuits
• General-purpose switching applications in electronic equipment

Procurement Notes

Verify the exact ordering code against the manufacturer's official documentation before purchase. Confirm that the Mini3-G1 package dimensions align with your PCB footprint requirements. Ensure the design operates within the specified absolute maximum ratings to maintain reliability. Check for any lifecycle status updates regarding maintenance or discontinuation directly from the supplier.

Selection Notes

Select this component when a combined NPN transistor and dual-resistor network is required for signal conditioning or level shifting. The 10 kΩ base resistor and 47 kΩ collector resistor define the specific biasing characteristics. Verify that the 50 V voltage rating and 100 mA current capacity meet the circuit demands. Consider the thermal constraints given the 200 mW power dissipation limit in the small package.

Part Context

This device belongs to the UNR221x series of transistors with built-in resistors manufactured by Panasonic Electronic Components. The series offers various resistor combinations to suit different digital circuit needs. The UNR2214 specifically pairs a 10 kΩ base resistor with a 47 kΩ collector resistor. These components are intended for standard general electronic equipment applications.

Replacement Considerations

Consult the official Panasonic semiconductor catalog for verified substitute part numbers. Cross-reference electrical parameters such as VCEO, IC, and hFE with potential alternatives. Ensure the replacement component matches the Mini3-G1 package outline for physical compatibility.
