BC56-10PAST-QX

Single Bipolar Transistors Overview

The BC56-10PAST-Q is an NPN medium power transistor from the Nexperia BC56PAST-Q series, rated for 80 V collector-emitter voltage and 1 A continuous collector current. It features a peak collector current capability of 2 A and operates within a junction temperature range of -55 °C to 150 °C. The device utilizes a DFN2020D-3 (SOT1061D) leadless package with side-wettable flanks. DC current gain (hFE) ranges from 63 to 160 at VCE = 2 V and IC = 150 mA. Thermal resistance from junction to ambient is 235 K/W in free air.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm reel packaging or tape-and-reel specifications, as datasheets typically list standard suffixes like 'Q'. Confirm AEC-Q101 qualification status directly with the manufacturer for automotive compliance requirements. Ensure the ordering code matches the exact gain bin required for the application design.

Single Bipolar Transistors Selection Notes

Select this component when space-constrained designs require medium power handling in a leadless footprint. The exposed heat sink facilitates efficient thermal dissipation compared to conventional packages. Verify that the required hFE bin aligns with the BC56-10PAST-Q specification (63 to 160). Consider the 80 V rating for applications exceeding standard 45 V logic levels but below higher voltage thresholds.

Single Bipolar Transistors Part Context

This part belongs to the BC56PAST-Q series, which includes complementary PNP transistors such as the BC53PAST-Q. The series is designed for automotive-grade reliability, meeting AEC-Q101 standards. It serves as a modern replacement for legacy through-hole or larger surface-mount transistors in compact electronics requiring robust switching and amplification capabilities.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible substitutes within the same family include BC56PAST-Q and BC56-16PAST-Q, differing primarily in gain bins. For general-purpose replacements, verify voltage and current ratings match or exceed 80 V and 1 A respectively.
