2N7002LT1G N-Channel MOSFET 60V 115mA – Whatsminer H3 CB2 V8 Motherboard Repair
The 2N7002LT1G (silk-screen marking 702) is an N-channel MOSFET rated at 60V / 115mA in a SOT-23 package, used on the Whatsminer H3 CB2 V8 control board for signal-level switching and logic interfacing. With an on-state resistance of 7.5Ω at 10V gate drive, a gate threshold of 2.5V and maximum power dissipation of 225mW, it handles the low-current switching tasks on the motherboard's supervisory and I/O circuits.
Role on the Whatsminer H3 Control Board
The CB2 V8 motherboard uses small-signal MOSFETs like the 2N7002 for logic-level switching — enabling or disabling peripheral circuits, driving indicator LEDs, and interfacing between the Allwinner H3 processor and the hashboard power sequencing logic. A failed 2N7002 can cause a control board to lose communication with one or more hashboards, prevent the miner from starting, or disable a monitoring function that the firmware relies on for normal operation.
Replacement Procedure
Power off the miner and remove the control board. Locate the failed 2N7002 — it is a 3-pin SOT-23 package marked 702, typically found near the processor or I/O connector area. Verify failure by checking gate-drain and gate-source resistance with a multimeter. Desolder with a fine-tip iron or hot air at 280–310 °C, clean pads, place the new device with correct pin orientation and reflow. Reinstall the board and confirm normal miner startup and hashboard detection.
