DMV1500HDFD6

RF Diode Overview

The DMV1500HDFD6 is a high-voltage semiconductor device designed for horizontal deflection stages in standard and high-resolution video displays with E/W correction. It integrates two distinct diodes within a single insulated TO-220FPAB package: a damper diode rated at 1500 V repetitive peak reverse voltage (VRRM) and 6 A average forward current, and a modulation diode rated at 600 V VRRM and 3 A average forward current. Both diodes feature very fast recovery characteristics, with typical reverse recovery times of 150 ns for the damper and 60 ns for the modulation diode. The component utilizes planar technology to ensure low static and peak forward voltage drops, minimizing power dissipation during operation.

RF Diode Feature Summary

• Dual-diode integration combining a 1500 V damper diode and a 600 V modulation diode in one package
• Insulated TO-220FPAB package providing 2000 V RMS isolation between leads and external heat sink
• Ultra-fast recovery performance optimized for high-frequency switching applications
• Low forward voltage drop specifications to reduce conduction losses

RF Diode Applications

• Horizontal deflection circuits in standard definition television sets
• High-definition CRT display systems requiring E/W correction
• Video display driver stages utilizing Turbo 2 600 V technology

RF Diode Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm that the specific ordering suffix matches the required lead configuration, as FD6 indicates bent leads while FD denotes straight leads. Ensure compliance with RoHS standards if environmental regulations apply to the assembly process. Check for obsolescence status prior to finalizing design-in decisions.

RF Diode Selection Notes

Select this component when designing horizontal deflection circuits that require both high-voltage blocking capability and rapid switching speeds. The integrated dual-diode structure simplifies PCB layout by reducing component count compared to discrete solutions. Verify thermal management requirements based on the junction-to-case thermal resistance of 3.8 °C/W and the maximum operating junction temperature of 150 °C.

RF Diode Part Context

This part belongs to the DMV1500HD series, which represents a specialized family of high-voltage diodes tailored for CRT display technologies. The series leverages STMicroelectronics' Turbo 2 technology to achieve superior switching performance compared to standard rectifiers. It serves as a dedicated solution for legacy video display hardware rather than general-purpose power conversion.

RF Diode Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other DMV1500 series variants or comparable high-voltage dual diodes from alternative manufacturers, ensuring matching VRRM ratings, recovery times, and package dimensions.
