DSK24 2A 40V Schottky Diode | Antminer S19jPro S19XP S21 Hashboard Repair
The DSK24 2A 40V Schottky diode (silkscreen mark K24) is a vital component on the Antminer S19jPro, S19XP, and S21 hashboards. Designed with major ratings tailored for ASIC mining applications, this Schottky diode delivers exceptional reliability and efficiency in the auxiliary rectification, freewheel, and protection circuits that surround the hashboard's primary power architecture.
Each DSK24 brings together the characteristics that matter most in mining hashboards: 2.0A average forward current (IF), ultra-fast reverse recovery, low forward voltage drop, and high surge capability up to 40A IFsM. The result is a part that sits in the hashboard's power path without wasting energy or generating excess heat — exactly what is required for sustained 24/7 operation. RoHS and WEEE compliant, ready for high-temperature soldering (260°C / 10s at terminals).
Reliable and Efficient Diode for Antminer Hash Boards
- Low-profile package — compact design for efficient use of board space.
- Automatic placement compatibility — facilitates easy integration into manufacturing processes.
- Ultra-fast reverse recovery — quick response and improved switching performance.
- Low power consumption, high efficiency — helps optimise energy usage on hashboards.
- Low forward voltage drop (0.50V / 0.55V / 0.70V / 0.85V depending on operating point) — minimises power loss.
- High surge capability — withstands sudden power surges up to 40A.
DSK24 Repair Use Case on Antminer S19j Pro / S19XP / S21
On the S19j Pro, S19XP, and S21 hashboards, K24-marked DSK24 diodes sit at multiple points in the power path. When one fails — typically as a short or open — the surrounding ASIC chain can lose its rail and drop offline, or the failed diode can pull down the local domain and produce a hash-rate cliff. Replacing the DSK24 with an original-spec part restores the power path and brings the chain back to full chip detection. Stock the DSK24 alongside ASIC chips and LDO ICs for a complete S19j Pro / S19XP repair kit.
