SRF1050

Diode Arrays Overview

The SRF1050 is a dual Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a common cathode configuration with two internal elements housed in an isolated TO-220AB flange mount package. The device is constructed from silicon and supports a maximum repetitive peak reverse voltage of 50V. It provides a continuous output current of 5A per element, with a maximum non-repetitive peak forward current of 120A. The unit operates within a temperature range of -65°C to 150°C and exhibits a maximum forward voltage of 0.75V.

• Guard ring design integrated for overvoltage protection
• High surge current capability suitable for demanding switching applications

Diode Arrays Applications

• Low voltage high frequency inverters
• Free wheeling rectification circuits
• Polarity protection implementations

Diode Arrays Procurement Notes

Verify the specific manufacturer designation on the component marking, as multiple vendors produce this part number. Confirm that the TO-220AB package variant matches the required thermal and mechanical specifications for the target assembly. Ensure compliance with RoHS 2002/95/EC standards if environmental regulations apply to the final product deployment.

Diode Arrays Selection Notes

Select this component when a dual common cathode Schottky rectifier is required for low voltage DC-DC conversion or freewheeling duties. The TO-220AB package facilitates direct heatsinking for thermal management. Consider the 50V rating and 5A current capacity against circuit load requirements. Verify that the 150°C maximum junction temperature aligns with the system's thermal envelope.

Diode Arrays Part Context

This device belongs to the SRF series of switchmode full plastic dual Schottky barrier power rectifiers. The series is designed for high-efficiency power supply applications where low forward voltage drop is critical. The TO-220AB form factor allows for robust mounting and heat dissipation compared to smaller surface-mount alternatives.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers' SRF1050 variants such as those from Jinan Jingheng or Shanghai Lunsure. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement maintains the same 50V reverse voltage and 5A current ratings.
