BCX56-16-QF

Overview

The BCX56-16-QF is an NPN medium power transistor from the Nexperia BCX56-Q series, housed in a SOT89 (SC-62) surface-mounted plastic package. It features an 80 V collector-emitter voltage rating and supports a continuous collector current of 1 A with a peak pulse capability of 2 A. The device offers three DC current gain selections; the BCX56-16 variant specifies a minimum hFE of 100 at IC = 150 mA. Qualified under AEC-Q101 standards, it operates within a junction temperature range up to 150 °C and includes thermal resistance values ranging from 250 K/W in free air to 93 K/W on specific PCB footprints.

Procurement Notes

Verify that the ordering suffix -QF corresponds to the standard BCX56-16-Q specification in the official Nexperia catalog. Confirm the package type remains SOT89 and check for any specific tape-and-reel requirements associated with the F suffix if applicable. Ensure the component meets the required AEC-Q101 qualification status for your target application environment.

Selection Notes

Select the BCX56-16-QF when a minimum DC current gain of 100 is required at 150 mA collector current. Consider this part for designs needing 80 V blocking capability and 1 A continuous current handling in a compact SMD footprint. Evaluate thermal performance based on the specific PCB copper area and ambient temperature conditions defined in the datasheet derating curves.

Part Context

This component belongs to the BCX56-Q series of NPN transistors designed for robust performance in industrial and automotive sectors. The series shares identical electrical characteristics and pinout configurations across its variants, differing only in current gain bins. The BCX56-16 variant provides a mid-range gain selection compared to the BCX56-Q and BCX56-10 options.

Replacement Considerations

Direct substitutes within the same family include BCX56-Q and BCX56-10-Q, which share identical electrical limits but offer different current gain ranges. Verify that the replacement part number matches the required hFE bin for your specific circuit design before implementation.
