UNR511T00L

Overview

The UNR511T00L is a composite device from the Panasonic UNR511x Series, featuring a Silicon PNP epitaxial planar transistor with built-in bias resistors. It operates in an S-Mini (SC-70) package with three terminals: Base, Emitter, and Collector. The component supports absolute maximum ratings of -50 V for collector-base and collector-emitter voltages, -100 mA collector current, and 150 mW total power dissipation at 25°C. Electrical characteristics include a forward current transfer ratio (hFE) ranging from 80 to 400 under specific conditions, a transition frequency of 80 MHz, and integrated input resistance values of 22 kΩ and 47 kΩ.

Feature Summary

• Integrates a PNP transistor with two internal bias resistors to reduce component count and equipment size.
• Utilizes an S-Mini type package designed for automatic insertion via tape/magazine packing.

Applications

• Digital circuits requiring downsized components
• General electronic equipment
• Office equipment
• Communications equipment

Procurement Notes

Verify the exact ordering suffix against official Panasonic documentation to confirm packaging details such as reel quantity or tape width. Confirm the product lifecycle status, as the series includes maintenance and discontinued types. Ensure compliance with RoHS Directive requirements for your specific manufacturing region before finalizing procurement orders.

Selection Notes

Select this component based on the required hFE rank and internal resistor tolerance. Verify that the operating voltage does not exceed the -50 V limits for both collector-base and collector-emitter configurations. Consider the thermal derating curves for total power dissipation if ambient temperatures deviate significantly from the standard 25°C test condition.

Part Context

This part belongs to the UNR511x Series, which offers various combinations of built-in resistors. The 'T' suffix specifically denotes the 22 kΩ and 47 kΩ resistor configuration within the S-Mini package family. This series is designed to replace discrete transistor and resistor networks in compact digital designs.

Replacement Considerations

Consult the official Panasonic replacement list for equivalent parts with similar hFE ranks and resistor values. Verify pinout compatibility and package dimensions when substituting with other manufacturers' transistors with built-in resistors.
