SSW47N60S 600V N-Channel MOSFET | High-Voltage Power Transistor for Antminer APW11 PSU Repair
The SSW47N60S is a new-generation 600V N-channel power MOSFET designed for efficient crypto-mining PSU repairs. Used on the Antminer APW11 power supply primary switching stage — features an advanced charge balancing mechanism for low RDS(on), reduced conduction losses, and excellent switching characteristics at the high frequencies of modern ASIC PSUs.
Headline specs: 600V VDS, 47A continuous ID, 70mΩ RDS(on), 391W power dissipation, 64nC total gate charge, 12ns rise time, TO-247 package. The combination of low Qg and fast switching keeps gate-drive losses low while delivering full primary-side switching power up to the APW11's 3000W+ envelope.
When to Replace the SSW47N60S
- APW11 PSU no output — primary-side switching MOSFET open or shorted.
- Blown mains fuse — shorted MOSFET took out the input fuse on power-up.
- Repeating over-current protection trip — degraded MOSFET causing controller to retry-and-fault.
- Visible cracking on the TO-247 body — overheat damage from cooling-fan failure or sustained over-temperature.
- Adjacent gate driver also degraded — voltage spike from a shorting MOSFET often kills the driver in the same event.

FAQ — SSW47N60S MOSFET
Q: Replace in pairs on the APW11 bridge stage?
A: Yes — when the PSU uses a bridge or half-bridge topology, replace in matched pairs to keep switching characteristics balanced. A single new MOSFET paired with an aged partner mismatches Qg and RDS(on), stressing both devices unevenly.
Q: Always check the gate driver IC when this MOSFET dies?
A: Strongly recommended. Voltage spikes from a shorting MOSFET often take out the driver in the same event. Skipping the driver replacement is a common cause of repeat failure within hours.
Q: TO-247 mounting torque?
A: Use the heat-sink manufacturer's torque spec. Overtightening cracks the package, undertightening lets junction temps climb. Re-paste the isolated mounting pad carefully before each install.
Q: Bulk pricing for APW11 PSU repair benches?
A: Yes — email contact@lys-sz.com for tape-and-reel quantities and matched gate-driver kits.
