Overview
The UNR511900L is a Silicon PNP epitaxial planar transistor with built-in resistors, designed for digital circuits. It features an S-Mini (SC-70) package with three pins: Base, Emitter, and Collector. The device integrates two internal resistors, R1 and R2, with nominal values of 1 kΩ and 10 kΩ respectively. Absolute maximum ratings include a collector-base voltage of -50 V, collector-emitter voltage of -50 V, collector current of -100 mA, and total power dissipation of 150 mW at 25°C ambient temperature. The junction temperature rating is 150°C.
Feature Summary
- Integrates dual resistors to reduce component count and equipment size
- Utilizes S-Mini type package for automatic insertion via tape/magazine packing
Applications
- Digital circuit interfaces
- Logic level conversion
- Switching applications in general electronic equipment
Procurement Notes
Verify the specific suffix '00L' against official Panasonic Industry documentation, as standard datasheets list 'UNR5119'. Confirm current lifecycle status, as the series includes maintenance or discontinued classifications. Ensure compliance with RoHS Directive requirements for the intended application environment.
Selection Notes
Select based on required resistor ratios and hFE gain ranks. The UNR5119 offers a 1k/10k configuration. Consider thermal derating for total power dissipation above 25°C. Verify input resistance tolerances (-30% to +30%) meet circuit biasing requirements.
Part Context
Part of the UNR511x Series (also referenced as UN511x), this component belongs to Panasonic's lineup of transistors with built-in resistors. These devices are engineered to simplify digital circuit designs by combining switching functionality with fixed biasing networks in a compact surface-mount form factor.
Replacement Considerations
Consult official Panasonic Industry resources for verified substitute part numbers. Cross-referencing should be performed carefully to ensure matching electrical characteristics, pinout compatibility, and package dimensions.
