Overview
The UNR9214J0L is a Silicon NPN epitaxial planar transistor with built-in resistors, designed for digital circuits. It features an SS-Mini (SC-89) package with three pins. The device includes two integrated bias resistors: R1 is 10 kΩ and R2 is 47 kΩ. Absolute maximum ratings at 25°C include a collector-base voltage of 50 V, collector-emitter voltage of 50 V, collector current of 100 mA, and total power dissipation of 125 mW. The transition frequency is specified at 150 MHz.
Feature Summary
- Integrates two bias resistors within a single compact package to reduce component count and equipment size.
- Utilizes the SS-Mini type package to facilitate automatic insertion via tape packing.
Applications
- Digital circuit switching
- Logic interface applications
- General electronic equipment
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. Ensure the component meets RoHS compliance requirements for the intended application. Confirm that the SS-Mini package dimensions align with the target PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a pre-biased NPN transistor with dual resistors is required for digital logic interfacing. The 10 kΩ and 47 kΩ resistor values provide specific base drive characteristics suitable for standard logic families. Consider the 125 mW power dissipation limit when designing thermal management solutions for dense circuit boards.
Part Context
This part belongs to the Panasonic UNR921xJ series of transistors with built-in resistors. The series offers various resistor combinations to suit different logic levels.
