SRF1650

Diode Arrays Overview

The SRF1650 is a dual common cathode Schottky rectifier manufactured by Taiwan Semiconductor. It utilizes silicon technology and is housed in an isolated TO-220AB package with three terminals. The device supports a maximum average forward rectified current of 8 amperes per element and withstands a repetitive peak reverse voltage of 150 volts. It features a low forward voltage drop of approximately 1 volt at rated conditions and handles a non-repetitive peak forward surge current of 200 amperes. The component operates reliably within a junction temperature range from -55 degrees Celsius to +150 degrees Celsius.

Diode Arrays Feature Summary

• Dual common cathode configuration for efficient bridge-less PFC or full-wave rectification
• Low forward voltage drop to minimize conduction losses and heat generation
• Isolated case connection for direct mounting to heatsinks without electrical insulation requirements

Diode Arrays Applications

• High-efficiency DC-DC converter output rectification
• Free-wheeling diodes in synchronous rectifier circuits
• Bridge-less power factor correction (PFC) topologies

Diode Arrays Procurement Notes

Verify the specific suffix codes on the ordering information, as they may indicate variations in packaging or lead-free status. Confirm that the TO-220AB package dimensions match your thermal management design. Ensure the 150V rating provides adequate margin for your circuit's peak inverse voltage requirements. Check for RoHS compliance documentation if environmental regulations apply to your assembly process.

Diode Arrays Selection Notes

Select this component when a dual Schottky arrangement is required in a single through-hole package. The 8A rating suits moderate power applications where efficiency is critical. Consider the thermal resistance of the TO-220AB package for your heatsinking strategy. Compare the forward voltage characteristics against other 150V Schottky options to optimize system efficiency. Ensure the 200A surge capability meets your inrush current demands.

Diode Arrays Part Context

This part belongs to Taiwan Semiconductor's series of high-performance Schottky rectifiers designed for general-purpose switching applications. The SRF1650 complements other devices in the family, such as the SR1650C0, which offers similar electrical characteristics but may differ in packaging or specific parameter tolerances. These components are engineered to replace standard silicon rectifiers in applications requiring faster switching speeds and lower power loss.
