SJPB-H4VL

Single Diodes Overview

The SJPB-H4 is a Schottky diode manufactured by Sanken Electric USA Inc. It features a maximum repetitive peak reverse voltage (VRM) of 40 V and an average forward current (IF(AV)) rating of 2.0 A. The typical forward voltage drop (VF) is 0.49 V at IF = 2.0 A, with a maximum of 0.55 V. Reverse leakage current (IR) is limited to 200 µA at VR = VRM and 25 °C, rising to 70 mA at TJ = 150 °C. The device operates within a junction temperature range of −40 to 150 °C and has a thermal resistance (Rth(J-L)) of 20 °C/W.

Single Diodes Procurement Notes

Verify the specific datasheet revision (e.g., Rev.1.3) and manufacturing date code before procurement. Confirm that the bare lead frame meets RoHS compliance requirements for your assembly process. Ensure soldering parameters strictly adhere to the specified limits: flow soldering at 260 °C for 10 seconds or reflow preheat between 150 °C and 200 °C. Validate component authenticity through authorized Sanken distributors.

Single Diodes Selection Notes

Select this component for circuits requiring low forward voltage drop and fast recovery characteristics at 40 V blocking levels. Evaluate thermal management based on the 20 °C/W junction-to-lead resistance and derating curves provided in the official documentation. Consider the operating temperature range up to 150 °C for high-reliability automotive or industrial environments where standard silicon rectifiers may exhibit higher losses.

Single Diodes FAQ

What is the maximum surge forward current capability?

The SJPB-H4 can withstand a nonrepetitive peak surge forward current (IFSM) of 50 A for a half-cycle sine wave lasting 10 ms.

How is the junction temperature defined for absolute maximum ratings?

The junction temperature (TJ) rating spans from −40 °C to 150 °C. Derating curves are provided assuming a constant TJ of 150 °C.
