TSML1020 is a surface mount Schottky rectifier diode produced by Vishay. It is a low-profile and low-on-resistance device, with a maximum operating voltage of 20 volts and a continuous current rating of 1 amp. It is commonly used in low voltage applications such as in small inverters, DC to DC converters, and battery chargers. It has good surge current capabilities and offers outstanding protection against transient voltage overshoots. It has a very low forward voltage drop and is compliant to the RoHS directive 2011/65/EU.
