PBSS4140DPNF

Overview

The Nexperia PBSS4140DPNF is an NPN/PNP low VCEsat transistor pair housed in a TSOP6 (SOT457) plastic package. It features a maximum collector-emitter voltage of 40 V and a continuous collector current of 1 A per transistor, with a peak pulse current capability of 2 A. The device provides a total power dissipation of 600 mW at 25 °C ambient temperature. Key electrical characteristics include a typical DC current gain (hFE) of 300 for the NPN section and 250 for the PNP section at specified currents. The transition frequency (fT) is rated at 150 MHz. The component is qualified to the AEC-Q101 standard for automotive applications.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and reel specifications. Confirm that the requested variant matches the required automotive qualification status and thermal performance parameters before finalizing procurement orders.

Selection Notes

Select this component when space constraints require replacing two discrete SOT23 packaged transistors with a single dual unit. Ensure the application operates within the 40 V voltage limit and 1 A current rating. Verify that the thermal resistance requirements align with the available board copper area for adequate heat dissipation.

Part Context

This part belongs to the PBSS4140DPN series of low VCEsat complementary transistor pairs. It utilizes the SC-74 (TSOP6) plastic package format designed for high-density surface mounting. The series is engineered to provide improved device reliability through reduced thermal stress during operation.

Replacement Considerations

Direct replacement requires verifying pin compatibility with the target footprint. Check if the original design utilized separate SOT23 packages, as this component consolidates them into one. Ensure the replacement maintains the required AEC-Q101 qualification if used in automotive systems.
