SJPB-D9V

Single Diodes Overview

The SJPB-D9 is a Schottky barrier rectifier diode manufactured by Sanken Electric USA Inc. It features a maximum repetitive peak reverse voltage (VRM) of 90 V and an average forward current rating (IF(AV)) of 1.0 A. The device exhibits a typical forward voltage drop (VF) of 0.74 V at 1.0 A, with a maximum limit of 0.85 V. Reverse leakage current (IR) is specified at 100 µA under standard conditions and increases to 30 mA at a junction temperature of 150 °C. The component operates within a junction temperature range of -40 °C to 150 °C and utilizes a surface-mount SJP package.
