Protected Mosfet
A protected MOSFET contains integrated transient surge protection circuitry and is less susceptible to electrostatic discharge and other transients, as compared to standard, unprotected MOSFETs.
Examples of protected MOSFETS in RepRap electronics are:
| Electronics | MOSFET Part Number | Notes |
|---|---|---|
| RAMPS | STMicroelectronics STP55NF06L | STripFETTM II Power MOSFET -- Integrated source-drain zener |
| Pololu Electronics | STMicroelectronics VNP14NV04-E | MOSFET OMNIFETII 40V 12A 0.02 ohm TO-220 -- Thermal, short, overvoltage, feedback, ESD |
| R2C2 electronics | Unprotected MOSFETS | External protection provided on board with zeners |
| Generation 7 Electronics | IRLB8743 & IRFZ44N | 30V 78A 0.0032 ohm & 55V 49A 0.017 ohm, internal zeners |
| Sanguinololu | Fairchild RFP30N06LE | 30A, 60V, ESD Rated, 0.047 Ohm, Logic Features
Level N-Channel Power MOSFETs -- 2KV esd, integrated source-drain zener, integrated gate-source zeners |
