The SL22-E3/52T from Vishay is a surface-mount Schottky barrier rectifier rated for 2A average forward current and 20V repetitive peak reverse voltage. It is designed for low-voltage, high-frequency rectification and power-protection applications requiring low conduction loss.
The SL22 features a low forward-voltage drop. At 25°C, maximum forward voltage is 0.395V at 1A and 0.44V at 2A. At 125°C and 2A, maximum VF is 0.32V, helping reduce conduction losses in low-voltage power converters.
The device supports a 100A non-repetitive peak forward surge current for an 8.3ms single half-sine waveform. A guardring structure provides overvoltage protection, while the rated voltage slew capability reaches 10,000V/µs. Vishay specifies typical applications including low-voltage high-frequency inverters, freewheeling, DC/DC converters and polarity protection.
The SL22-E3/52T is supplied in a low-profile SMB (DO-214AA) surface-mount package and meets MSL Level 1 requirements. Junction temperature ranges from -55°C to +125°C. The E3 suffix identifies the RoHS-compliant commercial-grade version, while 52T specifies 750 pieces on a 7-inch plastic tape-and-reel.
