Sanan SMS1200032P2 1200 V / 32 mOhm SiC Power MOSFET
1200 V SiC MOSFET with 32 mOhm typical on-resistance in TO-263-7L
Overview
The SMS1200032P2 is a 1200 V, 32 mOhm silicon carbide power MOSFET from Sanan Semiconductor supplied in a surface-mount TO-263-7L package. It combines high blocking voltage with low on-resistance, low switching losses and a fast intrinsic body diode, and operates up to a 175 C junction temperature. The part is RoHS compliant and targeted at solar inverters, uninterruptible power supplies, switch-mode power supplies and motor drives.
Key highlights
- 1200 V drain-source voltage with 32 mOhm typical RDS(on) at VGS = 18 V
- 57 A continuous drain current at 25 C and 41 A at 100 C case temperature
- Low switching loss: 286 uJ Eon and 89 uJ Eoff at 40 A, 25 C
- Fast body diode with 11 ns turn-on delay and 7 ns fall time at 25 C
- 0.45 C/W junction-to-case thermal resistance, 175 C maximum junction temperature
- Surface-mount TO-263-7L package, 143 A pulsed drain current
