Product Description
Vishay VS-40HF20 is a high-efficiency standard recovery switching diode designed for demanding power electronics applications. It supports a maximum continuous forward current of 40 A and a peak reverse repetitive voltage of 200 V, making it suitable for medium power rectification and switching tasks.
This diode is mounted using a screw type on a stud cathode, enhancing thermal dissipation and reliable mechanical stability. The robust DO-203AB package is industry-standard with compact dimensions conducive to space-conscious designs - measuring 20.08 mm in length, 22.9 mm in height, and 17.4 mm in width and diameter.
The diode offers a maximum forward voltage drop of 1.3 V which helps maintain efficiency under load. With a peak non-repetitive forward surge current up to 595 A, it can survive transient surges often seen in electrical circuits.
Its operating temperature range from -65°C to 190°C ensures reliable performance even in harsh industrial environments. The diode configuration is stud cathode providing stable electrical characteristics.
This diode's stud cathode mount enhances heat transfer and durability. Low peak reverse current of only 9 mA reduces energy losses. The package and electrical standards comply with typical industrial requirements though no specific certifications apply.
Widely used in power supply rectifiers, inverters, and other power management circuits. Designed for industrial, construction, and laboratory electronic applications requiring robust diode switching performance.
Vishay is well known for quality semiconductor components, and the VS-40HF20 model lives up to expectations with its solid electrical and mechanical design. This diode brings reliable standard recovery function in a compact and practical footprint suitable for diverse engineering challenges.
