SJPL-L4

Single Diodes Overview

The SJPL-L4 is a fast recovery diode manufactured by Sanken Electric USA Inc., rated for a maximum repetitive peak reverse voltage of 400 V and an average forward current of 3.0 A. It achieves a maximum reverse recovery time (trr) of 50 ns through optimized lifetime control. The device features a maximum forward voltage drop of 1.3 V at 25 °C and 3.0 A, with a thermal resistance from junction to lead of 20 °C/W. It operates within a junction temperature range of -40 °C to 150 °C and utilizes a bare lead frame compliant with RoHS standards.

Single Diodes Procurement Notes

Verify the specific datasheet revision (e.g., Rev.1.2) and manufacturing date code before procurement. Confirm that the bare lead frame packaging aligns with your soldering profile requirements, specifically flow or reflow limits. Ensure the component meets all applicable environmental regulations such as RoHS for your target market.

Single Diodes Selection Notes

Select this component when a 400 V blocking capability and 3.0 A continuous current are required in a compact surface-mount package. Consider the 50 ns reverse recovery time for high-frequency switching applications. Evaluate the thermal resistance of 20 °C/W against your system's heat dissipation capabilities to ensure the junction temperature remains within the specified operating range.

Single Diodes Part Context

The SJPL-L4 belongs to Sanken Electric's lineup of fast recovery diodes designed for general-purpose power conversion. It is housed in the SJP surface-mount package, which facilitates automated assembly. The device is engineered to replace through-hole alternatives in space-constrained designs while maintaining robust electrical performance for industrial and consumer electronics.

Single Diodes Replacement Considerations

Consult official Sanken Electric documentation for confirmed substitute part numbers. Verify that any replacement matches the 400 V rating, 3.0 A current capacity, and 50 ns reverse recovery time specifications.
