UNR91ALG0L

Overview

The Panasonic UNR91ALG0L is a PNP pre-biased single bipolar junction transistor (BJT) designed for surface-mount applications. It features a maximum collector-emitter voltage of 50V and a continuous collector current rating of 100mA. The device operates with a transition frequency of 80MHz and dissipates up to 125mW of power. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at 5mA and 10V, and a maximum saturation voltage of 250mV at 300µA base current and 10mA collector current. The component utilizes an SSMini3 (F3) package and exhibits a maximum collector cutoff current of 500nA.

Feature Summary

• Integrated biasing network simplifies circuit design by reducing external component count.
• Compact SSMini3 surface-mount package facilitates high-density PCB layouts.
• High-frequency operation capability supports signal processing in RF and switching applications.

Applications

• General-purpose switching circuits
• Driver stages for low-power loads
• Logic interface buffers

Procurement Notes

Verify the specific suffix code against official Panasonic documentation to confirm exact binning or tape-and-reel specifications. Confirm availability status as distribution data may indicate end-of-life or discontinuation phases. Ensure the ordering part number matches the required electrical tolerance and packaging format for production integration.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for 50V logic interfaces. Compare hFE and VCE(sat) requirements against load conditions. Consider thermal dissipation limits within the SSMini3 package for high-duty-cycle applications. Verify compatibility with automated placement equipment due to the small form factor.

Part Context

This component belongs to Panasonic's lineup of pre-biased transistors, which integrate resistors directly onto the die or package to simplify biasing networks. These devices are engineered to replace discrete resistor-transistor combinations, saving board space and assembly time in consumer electronics and industrial control systems.

Replacement Considerations

Cross-reference with other Panasonic pre-biased PNP transistors in the UNR series that share the SSMini3 package and 50V rating. Verify equivalent hFE bins and saturation voltages before substitution. Check for pin-compatible alternatives from other manufacturers if Panasonic supply is constrained.
