BDX54BG

Single Bipolar Transistors Overview

The BDX54BG is a PNP silicon power Darlington transistor manufactured by onsemi. It features an 8 A maximum DC collector current and an 80 V collector-emitter sustaining voltage minimum. The device operates within a temperature range of -65 °C to +150 °C. Packaged in a TO-220-3 through-hole case, it includes built-in base-emitter shunt resistors for stability. The typical DC current gain (hFE) is 2500 at 4.0 A dc.

Single Bipolar Transistors Feature Summary

• Monolithic construction with integrated base-emitter shunt resistors
• High DC current gain suitable for general-purpose amplifier applications
• Low collector-emitter saturation voltage characteristics

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Low-speed switching applications
• Complementary power transistor pairs

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm lead-free packaging status and exact electrical tolerances. Ensure the procurement channel provides the original onsemi documentation rather than third-party summaries. Confirm RoHS compliance details directly from the component marking or official specification sheet before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high current gain and robust power handling in a standard through-hole package. Consider the complementary NPN variant for push-pull configurations. Evaluate thermal management requirements given the 65 W power dissipation capability. Verify that the 80 V voltage rating aligns with the circuit's peak operating conditions.

Single Bipolar Transistors Part Context

This part belongs to the BDX53B/BDX54B series of plastic medium-power complementary silicon transistors. The series is designed for applications demanding high current capabilities and reliable switching performance. The BDX54BG specifically denotes the PNP configuration within this complementary pair family.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists for pin-compatible alternatives. Verify that any substitute maintains the same Darlington topology and voltage/current ratings.
