DK020LTP

Single Diodes Overview

The Littelfuse DK020LTP is a standard rectifier diode rated for 1000 V DC reverse voltage and 12.7 A average forward current. It utilizes an electrically isolated TO-220AB (ITO-220AB) through-hole package, facilitating efficient heat dissipation and secure mounting. The device supports a maximum non-repetitive peak surge current of 255 A and operates within a junction temperature range of -40°C to +125°C. Designed for robust power conversion applications, it features a low forward voltage drop and high reliability under thermal stress.

Single Diodes Procurement Notes

Verify the specific suffix 'LTP' corresponds to the tube packaging configuration as indicated by distributor listings. Confirm the manufacturer's latest Product Change Notification regarding molding compound approvals before finalizing procurement orders to ensure compliance with updated material specifications.

Single Diodes Selection Notes

Select this component when electrical isolation between the cathode and heatsink is required in high-power designs. The TO-220AB form factor simplifies mechanical integration compared to insulated variants. Ensure thermal management strategies account for the 12.7 A continuous current rating and ambient operating conditions up to 125°C junction temperature.

Single Diodes Part Context

This part belongs to Littelfuse’s Teccor® series of standard rectifiers, which offer ratings from 200V to 1000V and currents from 15A to 25A RMS. The DK020LTP specifically addresses applications requiring robust, isolated power rectification in compact through-hole layouts, bridging the gap between general-purpose diodes and specialized high-frequency devices.

Single Diodes Replacement Considerations

Cross-reference with other 1000V, 12.7A TO-220AB isolated rectifiers from Littelfuse or compatible manufacturers. Verify pinout compatibility and thermal resistance characteristics to ensure equivalent performance in existing circuit designs without modifying the PCB footprint.
