DSSK 20-013A DSSK 20-015A is a power Schottky rectifier with common cathode from IXYS, with very low VF and extremely low switching losses, suitable for switch mode power supplies (SMPS) and freewheeling diodes in low voltage converters.
The IXYS DSSK 20‑013A and DSSK 20‑015A are power Schottky rectifiers with a common cathode, offered in an international‑standard TO‑220 AB (TAB) package. They are intended for use as rectifiers in switch‑mode power supplies and as free‑wheeling diodes in low‑voltage converters.
Key features include a very low forward voltage drop, extremely low switching losses, low reverse‑current values and an epoxy that meets UL‑94V‑0 standards. The devices provide high reliability, low voltage peaks for reduced protection circuitry, and low noise switching. Technical data such as forward voltage, reverse voltage, current ratings and thermal characteristics are listed in the specifications.
