PBSS2515YPN/ZLX

Overview

The PBSS2515YPN/ZLX is an NPN/PNP low VCEsat transistor pair housed in a SOT363 (SC-88) plastic surface-mounted package. It features a maximum collector-emitter voltage of 15 V and a continuous collector current of 500 mA per transistor, with peak currents reaching 1 A. The device offers a typical collector-emitter saturation resistance of 300 mΩ at 500 mA. Total power dissipation is rated at 300 mW for the dual device, with a junction temperature limit of 150 °C. Transition frequencies are specified at 420 MHz for the NPN section and 280 MHz for the PNP section.

Feature Summary

• Low collector-emitter saturation voltage for efficient switching
• High current capability supporting up to 500 mA continuous operation
• Compact SOT363 package replaces two SC-70 devices on the same PCB area
• Reduced pick and place costs due to single-component integration

Applications

• General purpose switching and muting circuits
• Low frequency driver circuits
• LCD backlighting control
• Supply line switching applications
• Battery driven equipment such as mobile phones and handheld devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and manufacturing site codes. Ensure that the selected variant matches the required tape and reel specifications for automated assembly processes. Cross-reference the part number with the latest datasheet revision history to confirm product status and availability before finalizing procurement orders.

Selection Notes

Select this component when space constraints require replacing two separate SC-70 transistors with a single dual package. Consider the 15 V voltage rating and 500 mA current capability for general-purpose switching tasks. Evaluate the thermal resistance characteristics if operating near the maximum junction temperature limits. Verify compatibility with standard SMT reflow soldering profiles defined for the SOT363 package outline.

Part Context

This device belongs to Nexperia's portfolio of low VCEsat bipolar junction transistor pairs designed for compact consumer electronics. The SOT363 package provides a significant footprint reduction compared to discrete SC-70 solutions. It serves as a direct replacement for older dual-transistor configurations in portable battery-powered devices where board real estate and assembly efficiency are critical design parameters.

Replacement Considerations

Direct replacements include other Nexperia PBSS2515 series variants within the SOT363 package. Verify pinout compatibility and electrical parameters against the original design requirements when substituting components from different manufacturers or package types.

FAQ

What is the difference between the NPN and PNP transition frequencies?

The NPN transistor (TR1) has a higher transition frequency of 420 MHz, while the PNP transistor (TR2) has a transition frequency of 280 MHz under specified test conditions.

How does the SOT363 package benefit PCB design compared to SC-70?

The SOT363 package allows the integration of both NPN and PNP transistors into a single component, effectively replacing two separate SC-70 packaged devices and reducing the required PCB area.

What is the maximum total power dissipation for the device?

The total power dissipation for the entire dual device is limited to 300 mW when mounted on an FR4 PCB with a single-sided copper tin-plated standard footprint.
