UNR9218J0L

Overview

The UNR9218J0L is a Silicon NPN epitaxial planar transistor with built-in resistors, designed for digital circuits. It features an SS-Mini (SC-89) surface-mount package. Absolute maximum 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 transition frequency is 150 MHz. Electrical characteristics specify a forward current transfer ratio (hFE) minimum of 20 at IC = 5 mA and VCE = 10 V. The internal bias network consists of a base resistor (R1) of 0.51 kΩ and an emitter resistor (R2) of 5.1 kΩ.

Feature Summary

Integrates bias resistors to reduce component count and equipment size.
Utilizes SS-Mini package for automatic insertion via tape packing.

Applications

Digital circuit switching
General electronic equipment

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm exact resistance values and marking symbols. Confirm availability status as distribution listings may indicate end-of-life conditions. Ensure the source document matches the manufacturer's latest product standards before finalizing procurement decisions.

Selection Notes

Select this component when a low-current NPN switch with integrated biasing is required for space-constrained designs. Verify that the 0.51 kΩ base resistor and 5.1 kΩ emitter resistor align with the target logic interface requirements. Check thermal constraints to ensure operation remains within the 125 mW dissipation limit.

Part Context

This part belongs to the UNR921xJ series of transistors with built-in resistors manufactured by Panasonic Industry. The series offers various resistor combinations tailored for different digital logic levels. The UNR9218J variant specifically provides a low base resistance configuration suitable for faster switching or higher drive currents compared to high-resistance variants in the same family.

Replacement Considerations

Consult official Panasonic cross-reference lists for verified substitutes. Generic equivalents may not match the precise R1/R2 ratios or hFE specifications defined in the datasheet.
