DMV1500HDFD

RF Diode Overview

The DMV1500HDFD is a high-voltage semiconductor device designed for horizontal deflection stages in standard and high-resolution video displays with E/W correction. 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 typical reverse recovery time of 150 ns. The modulation diode provides a 600 V reverse voltage rating, a 3 A average forward current, and a typical reverse recovery time of 60 ns. Both diodes feature low static and peak forward voltage drops to minimize dissipation.

RF Diode Feature Summary

• Integrates both damper and modulation diodes into a single insulated package
• Features very fast recovery characteristics with specified turn-on switching parameters
• Utilizes planar technology to ensure high quality and optimal electrical performance
• Provides insulation rated at 2000 V RMS with a capacitance of 7 pF

RF Diode Applications

• Horizontal deflection stages in standard resolution video displays
• Horizontal deflection stages in high-resolution video displays
