Single Diodes datasheet and documents for SB140
Single Diodes Overview
The SB140 is a Schottky barrier rectifier diode manufactured by Diotec Semiconductor, designed for general-purpose applications. It features an average forward current (IFAV) of 1 A and a maximum repetitive peak reverse voltage (VRRM) of 40 V. The device exhibits a low forward voltage drop of less than 0.50 V at 1.0 A and 25°C, with a typical junction capacitance of 80 pF at 4 V. Reverse leakage current is specified as less than 0.5 mA at 25°C and less than 5 mA at 100°C when rated at VRRM. Peak forward surge current (IFSM) reaches 40 A under half-sine-wave conditions at 50 Hz. The component operates within a junction temperature range of -50°C to +150°C.
Single Diodes Feature Summary
