GBJ3510 1000V / 35A Bridge Rectifier for Whatsminer P21 PSU
Enhance the performance and reliability of your miner power supply with the GBJ3510 rectifier bridge. Specifically designed for miner PSU repair, this high-quality component offers exceptional surge capability and durability for AC-side rectification on Whatsminer P21 and similar high-power PSUs.
Impressive specifications: 1000V maximum repetitive peak reverse voltage and 1100V peak reverse non-repetitive. 35A maximum average forward rectified output current at 85°C handles the heavy AC-side current on mining PSU primary stages. 400A peak forward surge current capability provides reliable protection during line transients and inrush events — ensuring uninterrupted operation across years of 24/7 service.
Typical Use in Mining PSU Repair
- P21 PSU AC-side bridge failure — replacing failed bridge rectifier on primary input.
- Post-surge recovery — replacing bridges damaged by line transients / surge events.
- Aging recovery — replacing bridges showing thermal degradation after years of service.
- Production refurbishment — bulk bridge rectifier stock for high-volume P21 rebuild lines.
- General industrial SMPS repair — any 1000V+ high-current input-side rectification application.

FAQ — GBJ3510 Bridge Rectifier
Q: GBJ3510 vs GBU610 vs GBJ2010 — which to choose?
A: All are 1000V bridge rectifiers but at different current ratings. GBJ3510 = 35A (highest, P21-class PSU). GBJ2010 = 20A (mid-range, APW PSU). GBU610 = 6A (low-current, snubber / housekeeping). Match the rating to your PSU input current.
Q: How do I identify a failed bridge rectifier?
A: Typical signs: no DC bus voltage despite AC line present, blown input fuse, visible burn marks, audible "thump" at fault event. Test with multimeter diode mode — each of the 4 internal diodes should show forward Vf in one direction and open in the other. Short or open indicates failure.
Q: 400A surge — why such high spec?
A: Inrush current at PSU startup (charging bulk caps from 0V) can briefly hit hundreds of amperes. The 400A surge spec ensures the bridge survives without damage on each cold-start. Industrial mining PSUs cycle through thousands of starts over service life.
Q: Bulk pricing for P21 repair shops?
A: Yes — email contact@lys-sz.com with your monthly PSU rework volume for tier pricing on GBJ3510 stock.
