DMV1500MFD

RF Diode Overview

The DMV1500MFD is a high-voltage semiconductor diode assembly designed for horizontal deflection stages in video displays. It integrates a Damper diode and a Modulation diode within an insulated TO-220FPAB package. The Damper diode supports a repetitive peak reverse voltage of 1500 V, an average forward current of 6 A, and a maximum reverse recovery time of 135 ns. The Modulation diode provides a 600 V rating, 3 A average current, and a maximum reverse recovery time of 50 ns. Both components utilize planar technology to ensure low static and peak forward voltage drops for reduced power dissipation.

RF Diode Feature Summary

• Integrates Damper and Modulation diodes into a single insulated package
• Features very fast recovery characteristics with specified turn-on switching performance
• Utilizes planar technology for high quality and consistent electrical characteristics
• Provides low static and peak forward voltage drop to minimize thermal dissipation

RF Diode Applications

• Horizontal deflection stages in standard resolution video displays
• Horizontal deflection stages in high resolution video displays
• Video display systems requiring E/W (East/West) correction

RF Diode Procurement Notes

Verify the specific ordering suffix when sourcing this component. The base part number DMV1500MFD corresponds to the standard TO-220FPAB package configuration. An optional variant, DMV1500MFD5, utilizes the F5 bending lead configuration. Confirm that the required package style matches the intended PCB layout before procurement.

RF Diode Selection Notes

Select this component for applications requiring integrated damper and modulation functions in a single housing. Ensure the design accommodates the 1500 V rating for the damper section and the 600 V rating for the modulation section. Verify that the thermal management strategy accounts for the junction-to-case thermal resistance of 3.7 °C/W under expected operating loads.

RF Diode Part Context

This device belongs to the DMV series of damper modulation diodes manufactured by STMicroelectronics. It serves as a specialized solution for video display circuits, combining two distinct rectification functions into one physical unit. The series includes variants such as the DMV1500M and DMV1500MFD5, which share similar electrical specifications but differ in mechanical packaging details.
