BCP68-25,135

Overview

The Nexperia BCP68-25,135 is an NPN medium power transistor housed in a SOT223 (SC-73) surface-mounted plastic package. It features a collector-emitter voltage of 20 V and a continuous collector current capability of 2 A, with a peak pulse current of 3 A. The device offers two current gain selections; the -25 variant specifies a minimum DC current gain (hFE) of 160 at IC = 500 mA and VCE = 1 V. Total power dissipation reaches up to 1.35 W on a PCB with a 6 cm² collector pad. Transition frequency is typically 170 MHz.

Feature Summary

• High collector current capability for both continuous and pulsed operation
• Two distinct current gain selections available within the series
• High power dissipation capability supported by exposed heatsink design

Applications

• Linear voltage regulators
• MOSFET drivers
• Low-side switches
• Power management circuits
• Amplifiers
• Battery-driven devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and availability status. Confirm that the component meets RoHS3 compliance requirements as specified in the product data sheet. Ensure the selected part number corresponds to the correct current gain bin required for the circuit design specifications.

Selection Notes

Select this component when a 20 V NPN transistor with high current handling is required in a compact SMD form factor. The BCP68-25 variant provides higher minimum gain compared to the standard BCP68, ensuring better performance in linear applications. Evaluate thermal resistance values based on the specific PCB copper area allocated for the collector pad to ensure safe operating temperatures under load.

Part Context

This component belongs to the BCP68 series of NPN medium power transistors manufactured by Nexperia. The series utilizes the SOT223 package, which provides increased thermal conductivity through an exposed heatsink tab. The BCP68-25 designation indicates a specific binning for DC current gain, distinguishing it from the standard BCP68 model which has a lower minimum gain threshold.

Replacement Considerations

The BCP68-25 serves as a direct replacement for older Philips Semiconductors or NXP BCP68-25 units. Verify pinout compatibility with the SOT223 footprint. For automotive applications, consult Nexperia for qualified alternatives, as this specific product data sheet indicates non-automotive qualification.
