BD648-S

Overview

The BD648-S is a PNP Darlington transistor manufactured by Bourns Inc., designed for through-hole mounting in the TO-220 package. It features an 80V collector-emitter voltage rating and an 8A continuous collector current capacity. The device provides a power dissipation of 2W, with thermal derating applied linearly to a case temperature of 150°C at a rate of 0.4 W/°C. Specific electrical values apply for pulse times up to 0.3 ms with a duty cycle not exceeding 10%.

Feature Summary

High-current PNP Darlington configuration
Through-hole TO-220 packaging
80V voltage and 8A current ratings

Applications

Power switching circuits
Motor control systems
Industrial equipment drivers

Procurement Notes

Verify the exact part number BD648-S against official Bourns documentation to confirm specifications. Ensure the TO-220 package type matches system requirements. Check datasheet notes regarding thermal derating and pulse conditions for accurate application design. Confirm manufacturer authenticity through authorized channels.

Selection Notes

Select this component for applications requiring high current handling in a PNP configuration. Consider the TO-220 package for adequate heat dissipation given the 2W power rating. Evaluate thermal management strategies due to the specified derating curve. Ensure voltage and current demands remain within the 80V and 8A limits respectively.

Part Context

This component belongs to Bourns' single bipolar transistor lineup. It serves as a discrete semiconductor device for power electronics. The Darlington structure offers high current gain suitable for driving loads directly.
