SK12H45H

Single Diodes Overview

The SK12H45H is a silicon Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a single-phase, one-element configuration housed in the DO-201AD (DO-4) axial leaded package. The device is rated for a maximum average forward rectified current of 12 Amperes and offers a repetitive peak reverse voltage of 45 Volts. Key electrical characteristics include a low maximum forward voltage drop of 0.7 V at rated current and a non-repetitive peak forward surge current capability of 320 A. The component supports a maximum operating junction temperature of 200 °C and complies with RoHS standards.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging options. Ensure that the procurement documentation explicitly states compliance with relevant environmental directives such as RoHS. Cross-reference the part number with the latest revision history to avoid obsolete stock or discontinued variants. Confirm that the supplier provides traceable manufacturing data for quality assurance purposes.

Single Diodes Selection Notes

Select this component when an axial leaded Schottky rectifier is required for high-current applications up to 12A. The 45V rating suits low-voltage DC systems where low forward voltage drop is critical for efficiency. Consider the 200°C junction temperature limit for high-thermal environments. Compare against standard PN junction rectifiers if switching speed and reverse recovery charge are primary design constraints.

Single Diodes Part Context

This device belongs to the SK series of Schottky rectifiers from Taiwan Semiconductor. These components are designed to replace traditional PN junction rectifiers in applications requiring faster switching speeds and lower conduction losses. The DO-201AD package provides a balance between current handling capacity and board space efficiency for through-hole mounting designs.

Single Diodes Replacement Considerations

Direct replacements must match the 12A current rating, 45V reverse voltage, and DO-201AD package. Verify that substitute parts maintain equivalent forward voltage characteristics and thermal resistance values to ensure circuit performance parity.
