BC68PASX

Overview

The BC68PASX is an NPN medium power transistor manufactured by Nexperia, a subsidiary of NXP Semiconductors. It features a maximum collector-emitter voltage (Vceo) of 20 V and a continuous collector current (Ic) of 2 A. The device operates with a transition frequency (fT) of 170 MHz and supports a power dissipation of 420 mW. Packaged in a DFN2020D-3 surface-mount format, it includes an exposed heatsink for thermal management. The component is lead-free and RoHS compliant, designed for efficient heat transfer and reliable performance in compact electronic circuits.

Feature Summary

High current capability with a maximum rating of 2 A
Low voltage operation suitable for 20 V systems
Exposed heatsink design for superior thermal conductivity
Leadless very small SMD plastic package

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as the part is produced by Nexperia under the NXP Semiconductors portfolio. Confirm the specific suffix 'X' indicates the tape-and-reel packaging variant if required for automated assembly. Ensure compatibility with the DFN2020D-3 footprint and check for AEC-Q101 qualification status if automotive reliability is a mandatory project requirement.

Selection Notes

Select this component for applications requiring a compact NPN switch with moderate power handling. The 20 V rating limits usage to low-voltage logic or battery systems. The DFN2020D-3 package offers a balance between thermal performance and board space efficiency. Consider the PNP complement BC69PA for push-pull configurations. Evaluate thermal resistance requirements against the 420 mW dissipation limit.

Part Context

This transistor belongs to the BC68/BC69 series of medium power NPN/PNP transistors. It serves as a modern replacement for older through-hole packages like SOT223 variants, offering improved thermal performance via the exposed pad. The series is widely used in consumer electronics and industrial control boards where space constraints and switching speed are critical design factors.
