Introduction to ThermaFlat SiC MOSFET Family
Para Light Electronics has introduced the ThermaFlat SiC MOSFET family, addressing a significant thermal challenge in high-power design. The new semiconductor portfolio utilizes Para Light's Ultra-Low RDS(on) Drift Technology to deliver exceptional thermal stability, reduced conduction losses, and unmatched reliability.
Solving Power Electronics' Most Persistent Bottleneck
The global transition towards electrification is driving the need for higher output within smaller, cooler, and more efficient footprints. However, conventional silicon and SiC MOSFETs face a built-in constraint: temperature-dependent RDS(on) drift. As junction temperatures rise, escalating on-resistance can trigger a cycle of higher conduction losses, excessive heat generation, and expanded cooling requirements, ultimately degrading system efficiency and long-term reliability.
ThermaFlat Technology: Redefining Thermal Stability
Para Light's ThermaFlat technology directly addresses this thermal challenge. Unlike standard SiC MOSFETs, ThermaFlat devices maintain virtually flat on-resistance across wide operating temperatures while sustaining exceptionally low switching losses. In benchmark testing, the 650 V, 21mΩ TO-247 device exhibited an RDS(on) change of only approximately 8% as junction temperature swung from -25°C to +125°C.
Comparison of ThermaFlat and Conventional SiC MOSFETs
| Feature | ThermaFlat SiC MOSFET | Conventional SiC MOSFET |
|---|---|---|
| RDS(on) Drift | ~8% | Up to 20% |
| Operating Temperature | -25°C to +125°C | -25°C to +125°C |
| Switching Losses | Exceptionally low | Higher |
| System Efficiency | Improved | Reduced |
| Reliability | Unmatched | Lower |
