MF30H100CTHE3_B/P

Overview

The MF30H100CTHE3_B/P is a dual common-cathode high-voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology to enhance high-temperature performance and features a guardring for overvoltage protection. The device is housed in an ITO-220AB package with matte tin-plated leads. Key electrical specifications include a maximum repetitive peak reverse voltage of 100 V, a total maximum average forward rectified current of 30 A (15 A per diode), and a peak forward surge current of 275 A. The typical thermal resistance per diode is 4.6 °C/W.

Feature Summary

• High Barrier Technology designed for improved high-temperature operation
• Guardring structure provides enhanced overvoltage protection
• Low forward voltage drop contributes to reduced power loss and high efficiency
• AEC-Q101 qualified for automotive reliability standards

Applications

• High frequency rectification in switching mode power supplies
• Freewheeling diodes in DC/DC converter circuits
• Polarity protection applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and delivery mode. The HE3 suffix indicates RoHS compliance and adherence to JESD 201 class 2 whisker testing requirements. Confirm that the ITO-220AB package variant matches the intended PCB footprint and mounting torque specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual common-cathode configuration is required for space-constrained designs. The ITO-220AB package offers isolation voltage capabilities not present in surface-mount alternatives. Ensure the application operates within the specified junction temperature range of -65 to +175 °C and accounts for the higher thermal resistance compared to D2PAK variants.

Part Context

This part belongs to the MB30HxxCT/MF30HxxCT family of dual common-cathode Schottky rectifiers. While the MF prefix denotes the ITO-220AB through-hole package, the MB prefix corresponds to the D2PAK (TO-263AB) surface-mount version. Both share identical electrical characteristics but differ in mechanical form factor and thermal resistance values.

Replacement Considerations

The MB30H100CTHM3/I serves as the direct surface-mount equivalent within the same product family. Verify that the target PCB supports the ITO-220AB footprint if substituting from a D2PAK design, as pin configurations and mounting requirements differ between the two packages.

FAQ

What is the difference between the MF30H100CT and MB30H100CT?

The primary difference is the package style. The MF30H100CT uses the ITO-220AB through-hole package, while the MB30H100CT utilizes the D2PAK (TO-263AB) surface-mount package. Electrical ratings remain identical.

Does the HE3 suffix affect the electrical performance?

No, the HE3 suffix indicates RoHS compliance and halogen-free material composition. It also ensures the component meets the JESD 201 class 2 whisker test requirement without altering the electrical parameters.

Is this component suitable for automotive applications?

Yes, the device is AEC-Q101 qualified, making it suitable for automotive electronics applications requiring high reliability and robust performance under varying temperature conditions.
