UNR32A000L

Overview

The UNR32A0 is a Silicon NPN epitaxial planar transistor with a built-in resistor, designed for digital circuits. It features an SSS Mini3-F1 package and includes a base resistor (R1) of 47 kΩ with ±30% tolerance. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a collector current (IC) rating of 80 mA, and a total power dissipation (PT) of 100 mW at 25°C. The device exhibits a forward current transfer ratio (hFE) ranging from 160 to 460 at IC = 5 mA and VCE = 10 V. Transition frequency (fT) is specified at 150 MHz under conditions of VCB = 10 V and IE = -2 mA.

Procurement Notes

Verify the current lifecycle status directly with Panasonic Semiconductor before procurement, as the datasheet indicates maintenance or discontinuation stages. Confirm that the specific batch meets RoHS Directive compliance requirements. Ensure design margins respect absolute maximum ratings, particularly regarding transient states during power-on or mode-switching to prevent defects.

Selection Notes

Select this component when a compact NPN transistor with integrated biasing is required for standard digital logic applications. The 47 kΩ internal resistor simplifies circuit design by reducing external component count. Verify that the 80 mA collector current and 100 mW power dissipation limits accommodate the intended load and ambient temperature conditions without exceeding junction temperature specifications.

Part Context

The UNR32A0 belongs to the UNR series of transistors with built-in resistors manufactured by Panasonic Semiconductor. This series utilizes silicon NPN epitaxial planar technology optimized for digital switching applications. The product line focuses on miniaturization and efficiency, offering various resistance values within the same Mini3-F1 package format to support diverse circuit requirements.

Replacement Considerations

Consult Panasonic Semiconductor for verified substitute part numbers, as cross-referencing requires matching electrical characteristics and package dimensions. Ensure any replacement maintains compatibility with the 47 kΩ internal resistor value and the 50 V voltage rating.
