PBSS4240DPN,115

Overview

The PBSS4240DPN,115 is a complementary NPN/PNP low VCEsat transistor pair housed in the SOT457 (SC-74) plastic surface-mounted package. It features a maximum collector-emitter voltage of 40 V for both polarities. The NPN transistor supports a DC collector current of 1.35 A and a peak current of 3 A, while the PNP variant handles 1.1 A DC and 3 A peak. Equivalent on-resistance is rated at 200 mΩ for the NPN and 260 mΩ for the PNP. Total power dissipation reaches 600 mW per device under standard mounting conditions.

Feature Summary

• Complementary NPN/PNP configuration within a single compact package
• Low collector-emitter saturation voltage for high efficiency
• High collector current capability with elevated current gain
• Reduced printed-circuit board area requirements

Applications

• Complementary MOSFET driver circuits
• Dual supply line switching
• Half and full bridge motor drivers
• Multi-phase stepper motor drivers

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging quantity. Confirm that the component meets RoHS compliance standards required by your manufacturing process. Ensure the SOT457 footprint matches your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require matched NPN/PNP pairs with low saturation voltages. Verify that the thermal resistance characteristics align with your heat dissipation strategy. Ensure the base drive currents are sufficient to maintain the specified low VCEsat levels during operation.

Part Context

This part belongs to the PBSS series of low VCEsat transistors originally developed by NXP Semiconductors. Following the corporate restructuring in February 2017, the Standard Product business became Nexperia. The datasheet retains historical NXP references but identifies the current manufacturer as Nexperia B.V.

Replacement Considerations

Check for direct equivalents such as the PBSS4140DPN or other SC-74 packaged complementary pairs from Nexperia. Verify pinout compatibility and ensure that the replacement part meets or exceeds the 40 V voltage rating and current handling capabilities.
