UNR211900L

Overview

The UNR211900L is a Silicon PNP epitaxial planar transistor with built-in resistors, designed for digital circuits. It features a Mini3-G1 (SC-59) package with three pins. The device has a collector-base voltage of -50 V and a collector-emitter voltage of -50 V. Maximum collector current is -100 mA, with total power dissipation rated at 200 mW. The internal connection includes a base resistor (R1) of 1 kΩ and an emitter resistor (R2) of 10 kΩ.

Feature Summary

• Reduces equipment downsizing costs by integrating transistors and bias resistors into a single component.
• Miniature package design facilitates easy automatic insertion via tape packing and magazine packing.

Applications

• Digital circuit switching
• Logic interface applications
• General electronic equipment

Procurement Notes

Verify the specific suffix '00L' against Panasonic's official documentation to confirm availability status and packaging format. Check the manufacturer's website for the latest lifecycle stage information, as this series may be subject to maintenance or discontinuation plans.

Selection Notes

Select based on required resistance ratios between R1 and R2. The UNR2119 variant provides a 1:10 ratio suitable for specific biasing needs. Ensure the operating temperature range fits within the specified junction and storage limits for the target application environment.

Part Context

This component belongs to the UNR211x Series, which offers various combinations of integrated resistors. The UNR2119 specifically pairs a 1 kΩ base resistor with a 10 kΩ emitter resistor. Other series members provide different ratios like 1:1 or 1:47 to accommodate diverse circuit requirements.

Replacement Considerations

Compatible substitutes include other UNR211x variants such as UNR2118 or UNR211D if resistance values differ. Verify pinout compatibility in the SC-59 package before substitution.
