DMV1500L

RF Diode Overview

The DMV1500L is a high-voltage semiconductor component 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 section supports a repetitive peak reverse voltage of 1500 V and an average forward current of 4 A, while the modulation section handles 600 V and 3 A. Key electrical parameters include a maximum reverse recovery time of 170 ns for the damper and 50 ns for the modulation diode. Maximum forward voltage drops are specified at 1.5 V for the damper and 1.4 V for the modulation diode.

RF Diode Feature Summary

• Combines damper and modulation diodes into a single insulated package to reduce board space and simplify assembly.
• Features very fast recovery characteristics with specified turn-on switching performance for high-speed applications.
• Utilizes planar technology to ensure low static and peak forward voltage drop for reduced power dissipation.
• Provides high breakdown voltage capability suitable for demanding horizontal deflection circuits.

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 component status as obsolete before procurement planning. Confirm specific ordering suffixes such as FD5 for bent leads if required by mechanical constraints. Ensure compatibility with existing thermal management designs given the junction-to-case resistance values. Review datasheet specifications carefully to match circuit requirements against absolute maximum ratings.

RF Diode Selection Notes

Select this component when integrating both damper and modulation functions into a compact form factor is necessary. Consider the TO-220FPAB package for its insulation properties and thermal performance. Evaluate the trade-off between the 1500 V rating of the damper section and the 600 V rating of the modulation section against circuit voltages. Verify that the fast recovery times meet the switching frequency requirements of the target display application.
