SMBJ15CA TVS Diode 15V 600W (BM) – Control Board Protection for Antminer / Whatsminer / Avalon

SMBJ15CA 15V TVS Diode – Surge Protection for ASIC Miner Control Boards

The SMBJ15CA (BM marking) is a high-reliability TVS (Transient Voltage Suppression) diode designed to protect ASIC miner control boards from voltage spikes and transient surges.

Widely used across Antminer, Whatsminer, Innosilicon, and Avalon control boards, this diode helps prevent damage caused by lightning, power surges, and switching transients.

With a 600W peak pulse power rating (10/1000 μs) and up to 4kW surge capability (8/20 μs), the SMBJ15CA ensures robust protection for sensitive electronic components.

Built using advanced planar technology, it offers low leakage current, high thermal stability, and long-term reliability in demanding environments.
