What are the key features of BDX54CG?
- PNP Darlington configuration with minimum DC current gain (hFE) of 750, enabling 8 A load switching from a small microamp-level base drive
- Higher 100 V collector-emitter voltage rating compared to 80 V alternatives, providing greater margin in higher-voltage motor and solenoid applications
- 65 W power dissipation capability in TO-221 package with integrated freewheeling diode and base resistors for simplified inductive load circuit design
What is BDX54CG used for?
The BDX54CG is suited for PNP high-side power switching in industrial motor controllers, relay and solenoid drivers, and linear power supply regulators that operate at up to 100 V and 8 A. Its 65 W rated dissipation and integrated protective diode make it a robust drop-in solution for lighting dimmers, heater controls, and battery charger circuits where elevated supply voltages require extra headroom beyond standard 80 V Darlington devices.

Frequently Asked Questions
How does BDX54CG's 100 V rating improve design margin versus 80 V Darlington alternatives?
The BDX54CG is rated for a collector-emitter voltage of 100 V compared to the 80 V of devices like the BDX54B, providing a 25% higher voltage margin for applications with line transients or back-EMF spikes in motor drives, reducing the risk of avalanche breakdown during switching at nominal 48 V or 60 V supply rails.
What continuous collector current and power dissipation can the BDX54CG sustain?
The BDX54CG supports a continuous collector current of 8 A and a maximum power dissipation of 65 W in the TO-221 package, making it suitable for sustained high-current load switching in motor control and linear regulator circuits without requiring derating at moderate ambient temperatures up to about 25 °C.
Can BDX54CG be used as a direct replacement for an 80 V PNP Darlington in a 48 V motor drive system?
Yes. The BDX54CG's 100 V, 8 A, and minimum hFE of 750 are fully compatible with circuits designed around 80 V PNP Darlingtons, offering the same integrated freewheeling diode and base resistors while adding extra voltage headroom of at least 20 V over the supply, which is beneficial for absorbing inductive transients in 48 V motor drive designs.
What leadform options exist for the BDX54CG and how do they affect PCB assembly?
ON Semiconductor lists additional leadform options for the BDX54CG in the TO-221 (221A) package, allowing straight or formed lead configurations to match different PCB mounting heights and through-hole pitch requirements, enabling the same 8 A, 100 V Darlington die to be used across multiple board layout constraints without changing the ordering base part number.
