UNR91A6G0L

Overview

The UNR91A6G0L is a Silicon PNP epitaxial planar transistor with a built-in bias resistor, designed for digital circuits. It operates within an absolute maximum collector current of -80 mA and a collector-emitter voltage of -50 V. The device features a minimum forward current transfer ratio (hFE) of 160 at -5 mA and a transition frequency of 80 MHz. Total power dissipation is rated at 125 mW. It utilizes the SSMini3-F3 package, measuring 1.60 mm by 0.85 mm, which supports high-density mounting.

Feature Summary

• Integrates a single bias resistor to reduce component count and simplify circuit design.
• Optimized for high-density mounting and equipment downsizing.
• Contributes to low power consumption in digital applications.

Applications

• General electronic equipment
• Office equipment
• Communications equipment
• Measuring instruments

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation before procurement. Suffixes often dictate packaging formats or compliance standards rather than electrical function. Confirm availability status directly with the manufacturer, as components may be subject to planned maintenance or discontinuation schedules.

Selection Notes

Select this component when a compact PNP transistor with integrated biasing is required for standard digital logic interfaces. Ensure the operating environment remains within the specified temperature range of -55°C to +125°C. Verify that the load conditions do not exceed the 125 mW total power dissipation limit under worst-case ambient temperatures.

Part Context

This part belongs to the UNR91 series of transistors with built-in resistors manufactured by Panasonic Electronic Components. These devices are silicon PNP epitaxial planar types intended for general-purpose digital switching applications where space constraints and simplified biasing networks are critical design factors.

Replacement Considerations

Consult the official Panasonic cross-reference tools for verified substitutes. Generic replacements must match the PNP configuration, -50V rating, and SSMini3-F3 package dimensions to ensure physical compatibility and electrical performance equivalence.
