About the Product

10kV Surge Protection & 60ns Delay for Crypto Miner PSUs

Maximize uptime for your Whatsminer P21 with the SI8261BBD isolator, a 5kV RMS-rated gate driver engineered for crypto miner power supply repairs. Leveraging Silicon Labs’ proprietary isolation technology, this drop-in upgrade outperforms optocouplers with 10kV surge protection, 60ns propagation delay, and ±125°C thermal stability—critical for high-load ASIC mining environments.

 

Pin-Compatible Optocoupler Replacement for Reliable IGBT/MOSFET Control in Mining Rigs

Key crypto mining repair advantages:

  • Pin-compatible with optocouplers—no PCB redesign needed.
  • 4A peak output drives MOSFETs/IGBTs in mining PSUs and industrial inverters.
  • Rail-to-rail voltage and 0.6–4A adjustable current for precision control.
  • AEC-Q100 certified for reliability in extreme conditions.

Ideal for renewable energy inverters, UPS systems, and mining rig power modules, the SI8261BBD ensures longer lifespan and tighter performance matching than optocoupled alternatives.
