UNR32AA00L

Overview

The UNR32AA00L is a Silicon NPN epitaxial planar type composite transistor manufactured by Panasonic Electronic Components. Designed for digital circuits, this pre-biased device integrates internal bias resistors to facilitate high-density mounting and equipment downsizing while contributing to low power consumption. The component operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 80 mA. It features a transition frequency of 150 MHz and a maximum power dissipation of 100 mW. The unit is housed in an SSS Mini3-F2 surface-mount package.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count
• Optimized for high-density mounting and physical downsizing of electronic equipment
• Engineered to contribute to overall system low power consumption

Applications

• Digital logic interface circuits
• Switching applications in compact consumer electronics
• Signal buffering in space-constrained printed circuit boards

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm exact electrical tolerances and packaging configurations. Confirm current availability status as manufacturing lifecycles may affect supply continuity. Ensure the selected variant matches the required pinout and thermal characteristics for the target application design.

Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required. Verify that the 50 V breakdown voltage and 80 mA current rating exceed the maximum operational loads. Consider the SSS Mini3-F2 package dimensions for PCB layout constraints and ensure the 150 MHz frequency response meets the signal processing requirements.

Part Context

This part belongs to the UNR32 series of pre-biased transistors from Panasonic. These devices are engineered specifically for digital circuit applications where board space is limited. The series utilizes silicon epitaxial planar technology to provide reliable switching performance in a miniature footprint suitable for modern portable and industrial electronics.

Replacement Considerations

Consult official Panasonic cross-reference data for verified substitutes. Generic equivalents may differ in internal resistor ratios or hFE characteristics. Validate any alternative component against the original 50 V rating and 80 mA current limit before implementation.
