D45C8

Single Bipolar Transistors Overview

The D45C8 is a PNP power amplifier transistor manufactured by ON Semiconductor, originally sourced from Fairchild Semiconductor. It features a collector-emitter voltage of -60 V and a continuous collector current of -4.0 A. The device operates within a junction temperature range of -55 to +150 °C and provides a total device dissipation of 60 W at 25°C ambient temperature. Key electrical characteristics include a DC current gain (hFE) ranging from 20 to 120, a collector-emitter saturation voltage of -0.5 V at -1.0 A, and a current gain bandwidth product of 32 MHz. The component utilizes a TO-220 package with a thermal resistance of 2.1 °C/W from junction to case.

Single Bipolar Transistors Procurement Notes

Verify the exact part number against the official ON Semiconductor database, as historical Fairchild parts may have undergone nomenclature changes during integration. Confirm that the specific revision matches your design requirements. Ensure compliance with RoHS standards if applicable to your manufacturing process. Always validate final specifications directly with authorized distributors or the manufacturer before procurement.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a PNP power transistor with a 60V rating and up to 4A continuous current capability. Consider the TO-220 package for adequate heat dissipation in high-power scenarios. Evaluate the hFE range and saturation voltages to ensure compatibility with your drive circuitry. Verify thermal management strategies align with the specified junction-to-case and junction-to-ambient thermal resistances.
