UNR32A6G0L

Overview

The Panasonic UNR32A6G0L is a Silicon NPN epitaxial planar transistor with a built-in resistor, designed for digital circuits. It features a collector-emitter voltage (VCEO) of 50 V and a maximum collector current (IC) of 80 mA. The device has a total power dissipation (PT) of 100 mW at 25°C and operates within a junction temperature range up to 125°C. Key electrical characteristics include a forward current transfer ratio (hFE) ranging from 160 to 460 at IC = 5 mA, and a transition frequency (fT) of 150 MHz. The internal base resistor (R1) is nominally 4.7 kΩ with a tolerance of ±30%. The component is housed in an SSSMini3-F2 surface-mount package.

Feature Summary

• Integrated base resistor simplifies circuit design by reducing component count.
• Compact SSSMini3-F2 package facilitates high-density mounting and equipment downsizing.
• Optimized for low power consumption in digital logic applications.

Applications

• Digital switching circuits
• General-purpose electronic equipment
• Office automation devices

Procurement Notes

Verify the specific ordering suffix against official distributor databases to ensure correct packaging and lifecycle status. Confirm RoHS compliance documentation matches the required regulatory standards for your region. Check for any recent maintenance or discontinuation notices directly from Panasonic Industry to avoid sourcing obsolete inventory.

Selection Notes

Select this component when a compact NPN pre-biased transistor is required for standard digital logic levels. Ensure the 50 V collector-emitter rating exceeds the maximum operating voltage. Verify that the 80 mA collector current capability meets the load requirements. Consider the 4.7 kΩ internal resistance value for appropriate base drive calculations.

Part Context

This part belongs to the UNR32 series of transistors with built-in resistors manufactured by Panasonic Industry. These components are specifically engineered as replacements for discrete resistor-transistor networks, offering space savings on printed circuit boards. The series is widely used in consumer electronics and industrial control systems where small form factors are critical.

Replacement Considerations

Consult official Panasonic cross-reference lists for verified substitutes. Generic equivalents may differ in hFE tolerances or internal resistor values. Ensure any replacement maintains the SSSMini3-F2 footprint and identical pinout configuration to prevent board redesign.
