Overview
The UNR9212J0L 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. Key electrical ratings include a collector-emitter voltage of 50 V, a collector current of 100 mA, and a total power dissipation of 125 mW at 25°C. The component integrates two bias resistors: R1 is 22 kΩ and R2 is 22 kΩ. The forward current transfer ratio (hFE) ranges from 60 to 400 under standard test conditions.
Feature Summary
- Integrates dual bias resistors to reduce circuit board space and component count.
- Utilizes the compact SS-Mini package suitable for automated tape packing insertion.
Applications
- Digital logic interface circuits
- Switching applications in general electronic equipment
- Signal level conversion
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging details. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the part number with official Panasonic Electronic Components catalogs to validate availability and current specifications before finalizing procurement plans.
Selection Notes
Select this component when a single NPN transistor with integrated base and emitter resistors is required to simplify digital switching designs. Verify that the 22 kΩ resistor values align with the target drive currents and logic levels. Confirm that the 50 V voltage rating and 125 mW power dissipation are sufficient for the operating environment.
Part Context
This device belongs to the UNR921xJ series of transistors with built-in resistors manufactured by Panasonic Electronic Components. The series offers various resistor combinations to suit different digital circuit requirements while maintaining a standardized small outline package format.
Replacement Considerations
Consult the official datasheet for direct substitute part numbers within the same series or equivalent components from other manufacturers. Verify pinout compatibility and electrical parameter margins before implementing any replacement.
