UNR211000L

Overview

The UNR211000L is a Silicon PNP epitaxial planar composite device featuring built-in bias resistors, designed for digital circuits. It operates with a maximum collector current of -100 mA and a collector-emitter voltage rating of -50 V. The component dissipates up to 200 mW of power and utilizes the Mini3-G1 (SC-59) surface-mount package. This specific variant includes a single base resistor (R1) with a nominal value of 47 kΩ.

Feature Summary

• Integrates a pre-biased transistor with an internal resistor to reduce external component count and board space.
• Utilizes a compact Mini3-G1 surface-mount package suitable for automated tape packing and magazine insertion.

Applications

• Digital logic interface circuits
• Switching applications in general electronic equipment
• Signal control within office and communication devices

Procurement Notes

Verify the exact part number against official Panasonic documentation to confirm availability status. Check for lifecycle stages such as planned maintenance or discontinuation before finalizing procurement plans. Ensure compliance with RoHS directives applicable to your region. Confirm that the SC-59 footprint matches your PCB design requirements prior to ordering.

Selection Notes

Select this component when a PNP transistor with a fixed base resistance is required for digital switching. Verify that the 47 kΩ internal resistor value aligns with your circuit's drive requirements. Ensure the -50 V voltage rating and -100 mA current capacity meet the load specifications. Consider the Mini3-G1 package dimensions for spatial constraints.

Part Context

This component belongs to the UNR211x Series, which encompasses various PNP transistors with different internal resistor configurations. The series is engineered for cost reduction through downsizing and part consolidation in digital circuit designs. It represents a standard solution for replacing discrete transistor and resistor combinations in compact electronics.

Replacement Considerations

Direct substitutes include other PNP pre-biased transistors with similar electrical ratings and resistor values. Verify pinout compatibility and package dimensions (SC-59/Mini3-G1) to ensure physical interchangeability without PCB redesign.
