PMD5003K,115

Overview

The PMD5003K is a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor paired with a high-speed switching diode in an SOT346 (SC-59A/TO-236) package. It features a collector-emitter voltage of -40 V, a continuous collector current of -1 A, and a peak collector current of -2 A. The integrated diode supports a forward current of 0.2 A with a maximum forward voltage of 1.1 V at 200 mA.

Feature Summary

• Integrates a low saturation voltage PNP transistor with a high-speed switching diode for base-emitter junction protection.
• Features application-optimized pinout and internal connections to minimize layout effort and reduce component count.
• Provides a space-saving solution suitable for compact surface-mounted designs.

Applications

• Power MOSFET driver

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging configuration. Confirm that the SC-59A package variant matches the design footprint requirements. Cross-reference the marking code D6 with incoming inspection standards to validate authenticity and revision status before production integration.

Selection Notes

Select this component when a compact driver solution requires both switching capability and reverse base-emitter protection. The BISS technology ensures low saturation voltage for efficient power handling. Ensure the PCB thermal management strategy accounts for the specified junction-to-ambient thermal resistance values under expected duty cycles.
