FSV20120V

Single Diodes Overview

The FSV20120V is a 20 A, 120 V ultra-low forward voltage Schottky rectifier manufactured by onsemi. It utilizes Trench Schottky technology to achieve a typical forward voltage drop of 0.79 V at 20 A and a maximum reverse leakage current of 35 µA at 120 V. The device operates within a junction temperature range of −55°C to +150°C and features a low thermal resistance of 40°C/W (maximum) with an optimized land pattern. Packaged in a TO-277 (CASE 340BQ) surface-mount configuration with a typical height of 1.1 mm, it supports non-DAP applications and complies with RoHS standards.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging details, as the standard FSV20120V is supplied in tape and reel quantities of 5000 units. Ensure compliance with environmental requirements, noting that this component is Pb-Free, Halogen Free, and RoHS compliant. Confirm that the application design accommodates the non-DAP option only, as specified in the datasheet features.

Single Diodes Selection Notes

Select the FSV20120V for designs requiring high efficiency and compact form factors due to its very low profile and ultra-low forward voltage characteristics. Consider the thermal management capabilities provided by the low thermal resistance when designing for high ambient temperatures or high average forward currents. Validate performance against the absolute maximum ratings, particularly the peak repetitive reverse voltage and non-repetitive surge current limits.

Single Diodes Part Context

This component belongs to onsemi's family of ultra-low VF Schottky rectifiers designed for high-efficiency power conversion. It is part of the broader portfolio of discrete semiconductor devices offered by onsemi, specifically targeting applications where minimizing conduction losses and reducing physical footprint are critical design constraints.

Single Diodes Replacement Considerations

Consult official cross-reference documentation or contact onsemi technical support for verified substitute part numbers. Do not assume functional equivalence based solely on matching electrical parameters without verifying package compatibility and thermal characteristics.
