DTV56F-E3/45

The Vishay General Semiconductor DTV56F-E3/45 is a high voltage damper diode designed for horizontal deflection circuits in CRT-based high-resolution displays and monitors. It has a maximum repetitive peak reverse voltage of 1500 V and an average forward current rating of 10 A, with a typical forward voltage of 1.5 V at 6 A and 125°C. The device features a very fast reverse recovery time of 135 ns and a typical forward recovery time of 350 ns, supporting high-efficiency low-switching-loss operation.

The diode is supplied in the ITO-220AC full-pack isolated-tab package, suitable for through-hole mounting. The package provides 1500 V isolation voltage between terminals and heatsink, and meets MSL level 1 and RoHS Directive 2002/95/EC compliance. It is designed to handle 130 A peak forward surge current under 8.3 ms single half-sine-wave conditions, making it robust in high-stress deflection circuits.

This part is classified by the manufacturer as End of Life and Not for New Design, with the last available purchase date of 31-May-2011. It has been used in legacy display equipment and may be available through remaining inventory or aftermarket sources. The E3 suffix indicates consumer grade with lead-free matte tin plated terminals that meet J-STD-002 and JESD 22-B102 solderability requirements.

The device operates over a junction and storage temperature range of -55°C to +150°C. With its fast recovery characteristics, good surge capability, and isolated package, it remains suitable for service and repair of high voltage damper applications in older display systems.
