Does anyone have the part No of the power Mosfets used in the Pololu 36V8 Stepper controller ?
Mosfet Part No needed.

Hi Max,
Web clip.
The Pololu 36V8 Stepper Motor Driver uses
N-channel MOSFETs in a discrete dual H-bridge arrangement controlled by a Texas Instruments DRV8711 IC. The specific model numbers of the MOSFETs used are FDMC8858 (N-channel) and FDM8854 (N-channel) manufactured by ON Semiconductor (formerly Fairchild).
The board has eight N-channel MOSFETs in total (four for each motor phase), with four on the top side (marked 8858) and four on the bottom side (marked 8854). These are power MOSFETs designed for high efficiency and high-current applications, enabling the board to deliver up to 8 A continuous per phase without a heat sink.

On the bottom side of the module I see 9 chips marked "BV1MVH" are those the mosfets?

They appear to be dual MOSFETs; if so, they would only need four, not eight, as there appears to be??
The BV1MVH is a single channel mosfet.
Pins 1-3 are the Source
Pin 4 is the Gate
Pins 5-8 are the Drain
Can't seem to locate a spec sheet or source to purchase for these devices (BV1MVH)??
It is a little low on the power-current values.
BTW, Digikey shipping has gone from a flat rate CAN$8.00 to US$20.00, since tariffs were introduced!
Makes it a little hard for small orders, too bad, they used to be my first go-to!
I am looking at NTD20N03L27T4G .
