Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance details. The M3 suffix indicates halogen-free, RoHS-compliant construction and commercial grade classification. Confirm package code 4W corresponds to the tube delivery mode with a base quantity of 50 units per tube. Ensure technical parameters meet application requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring low forward voltage drops at elevated temperatures. The TMBS technology provides superior performance compared to standard Schottky rectifiers. Verify thermal management capabilities as the device has a typical thermal resistance of 4.0 °C/W from junction to case. Ensure the operating environment stays within the specified -55 °C to +150 °C junction temperature range.

Single Diodes Part Context

This part belongs to the VF series of high-voltage Trench MOS Barrier Schottky rectifiers from Vishay. These devices are engineered to minimize conduction losses while maintaining robust reverse blocking capabilities. The ITO-220AB package allows for effective heat dissipation through direct mounting to heatsinks, supporting high current applications in compact form factors.

Single Diodes Replacement Considerations

Direct replacements must match the 150 V rating, 20 A current capacity, and ITO-220AB package. Verify forward voltage specifications at relevant load currents to ensure equivalent efficiency. Check thermal resistance values to maintain adequate cooling performance in the existing design.

Single Diodes FAQ

What is the maximum instantaneous forward voltage at 20 A?

The maximum instantaneous forward voltage at 20 A is 1.60 V at 25 °C and 0.84 V at 125 °C.

Does the M3 suffix affect the electrical function of the device?

No, the M3 suffix denotes material compliance including halogen-free and RoHS status, along with meeting JESD 201 class 1A whisker test requirements, without altering electrical performance.
