DMP34M4SPS TPCA8128 MOSFET P-Channel Hashboard Antminer S11 S15 T15

DMP34M4SPS / TPCA8128 P-Channel MOSFET | 30V / 34A 4.8mΩ U-MOSVI Power MOSFET in 8-SOP Package for Antminer S11 / S15 / T15 Hashboard Repair and Low-Side-Switch Cryptominer Power Management Applications

The DMP34M4SPS / TPCA8128 P-Channel MOSFET is the workhorse switching element in Antminer S11, S15, and T15 hashboards. Drop-in replacement for failed P-channel MOSFETs during hashboard repair, refurbishment, or production-line assembly across the legacy Antminer S11 / S15 / T15 generation.

Designed specifically for cryptomining applications, the DMP34M4SPS-13 delivers exceptional power management with minimised RDS(on) and excellent switching performance. Drain-source voltage (Vdss) of 30V and continuous drain current (Id) of 34A at 25°C (Ta) make it ideal for handling the demanding power requirements of cryptomining hashboards. Low drive voltage requirements and maximum RDS(on) of 4.8 mΩ at 17A / 10V ensure efficient power flow and reduced conduction losses — important on hashboards running 24/7 where every milliwatt of conduction loss compounds into significant heat and electricity cost.

Typical Use in Antminer S11 / S15 / T15 Hashboard Repair

• Hashboard P-channel switch failure — most common P-channel MOSFET swap on S11 / S15 / T15 boards.
• Hot-failure recovery — replacing MOSFETs after thermal runaway events.
• Cold-failure recovery — replacing degraded MOSFETs showing efficiency drop.
• Production refurb workflow — bulk P-channel MOSFET stock for line-based hashboard rebuilds.
• General P-channel switching — high-current low-voltage P-channel applications outside mining.

FAQ — DMP34M4SPS P-Channel MOSFET

Q: Where does the DMP34M4SPS sit in the S11 / S15 / T15 hashboard schematic?
A: Typically used in the per-domain power-gate switching role on the hashboard — controlling power delivery to specific ASIC domains. Identify the failed device by part-number marking on the PCB silkscreen before ordering replacements. Visual check + ESR / R(D-S) test confirms which devices to swap.

Q: Can I substitute another 30V P-channel MOSFET?
A: Functionally yes — any 30V P-ch MOSFET in matching 8-SOP package with similar RDS(on) (~4.8mΩ) and Id (~34A) works. However, for OEM-spec repair, stick with DMP34M4SPS / TPCA8128 to avoid PCB pad mismatches and preserve the original thermal envelope.

Q: How do I diagnose a failed P-channel MOSFET on hashboard?
A: Failed P-channel MOSFETs typically show short circuit between drain and source (D-S short). Test with multimeter resistance mode (D-S should show open in the OFF state). Visible burn marks or cracked package confirm catastrophic failure.

Q: Bulk pricing for S11 / S15 / T15 repair shops?
