Engineered with a molybdenum barrier metal and an epitaxial construction featuring oxide passivation and an integrated guard-ring for reverse stress protection, this semiconductor delivers high-efficiency rectification with minimal switching noise. It is rated for a repetitive peak reverse voltage of 45V and supports a total average forward current of 20A (10A per diode leg) with a maximum forward voltage drop of 840mV. Designed to handle high current capacities, the device exhibits a non-repetitive peak forward surge current rating of 150A and operates across a wide junction temperature range from -65°C to 150°C. This Schottky rectifier is optimized for high-frequency, low-voltage power conversion topologies, making it suitable for use as a freewheeling diode, polarity protection element, or output rectifier in switch-mode power supplies (SMPS) and DC-DC converters. Its majority carrier conduction mechanism ensures low stored charge and reduced power loss, thereby improving overall system efficiency in industrial power distribution and motor drive auxiliary circuits. The TO-220AB package facilitates reliable thermal management through standard through-hole heatsink mounting, ensuring stable electrical performance under continuous high-load operating conditions. ## Specifications | Parameter | Value | |---|---| | No. Of Pins | 3Pins | | Product Range | - | | Qualification | - | | Diode Mounting | Through Hole | | Diode Case Style | TO-220AB | | Diode Configuration | Dual Common Cathode | | Forward Voltage Max | 840mV | | Forward Surge Current | 150A | | Average Forward Current | 20A | | Operating Temperature Max | 150°C | | Repetitive Peak Reverse Voltage | 45V | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2674306/) ## **Schottky Barrier Rectifiers** **Description** Using the schottky barrier principle with a molybdenum barrier metal.
