Dopoochai Set 3mp4001 -
The unit features three dials on the front face:
In high-current DC-DC converters (e.g., 24V to 5V at 50A+), using a matched set like the 3MP4001 for the high-side and low-side switches minimizes shoot-through and ringing.
The output relay contacts (terminals 6-7-8) should be wired in series with the magnetic contactor coil. Do not attempt to switch the motor load directly with the 3MP4001; it is a signal-level relay, not a power contactor. dopoochai set 3mp4001
One of the biggest selling points of this set is its versatility. Here are three ways you can style the 3MP4001:
The dopoochai set 3mp4001 can directly replace the following popular part numbers without changing the gate drive circuitry: The unit features three dials on the front
| Original Part | Replacement Notes | | :--- | :--- | | IRFZ44N | Vds is 40V vs 55V (check your voltage first). Rds(on) is 1.8mΩ vs 17.5mΩ – huge improvement. | | IRFB4110 | Very close match. 3MP4001 has slightly lower gate charge, so switching losses are lower. | | Toshiba TK150E04 | Identical specs. Direct drop-in. | | STP120N4F6 | Superficial. The 3MP4001 has better ESD protection. |
Warning: Do not use the 3MP4001 in circuits designed for 60V+ MOSFETs (e.g., IRFZ48). The 40V absolute maximum will cause immediate avalanche breakdown. For Google Home:

Connect the incoming phases strictly to L1, L2, L3 as marked on the relay case. If you use the Phase Sequence protection feature, reversing any two wires will cause the relay to trip immediately. This is normal behavior—swap the wires back.
