BC53-10PASTX

Single Bipolar Transistors Overview

The BC53-10PASTX is a PNP medium power transistor from the Nexperia BC53PAST series, housed in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD package with side-wettable flanks. It features a collector-emitter voltage of -80 V and a continuous collector current of -1 A. The device offers three current gain selections; the BC53-10 variant specifies a DC current gain range of 63 to 160 at VCE = -2 V and IC = -150 mA. Total power dissipation reaches 1 W on a PCB with a 1 cm² collector pad.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the BC53-10PAST designation aligns with the intended hFE binning requirements for your circuit design. Ensure the procurement documentation references the correct SOT1061D package outline for footprint compatibility.

Single Bipolar Transistors Selection Notes

Select this component when space constraints require an ultra-thin profile while maintaining medium power handling capabilities. The exposed heat sink facilitates efficient thermal transfer to the PCB copper area. Verify that the application environment supports the specified junction temperature limits and that the leadless package soldering process accommodates the side-wettable flank design.

Single Bipolar Transistors Part Context

This part belongs to the BC53PAST series, which includes complementary NPN types such as the BC56PAST. The series utilizes the DFN2020D-3 package to reduce printed-circuit board area requirements compared to traditional leads. The BC53-10PAST specifically provides a standardized gain range suitable for general-purpose amplification and switching tasks where compact form factors are prioritized.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible substitutes within the same package include other members of the BC53PAST series, such as the BC53PAST or BC53-16PAST, provided their respective current gain ranges meet the circuit requirements.
