The Advantages of TOLT Technology

- Switching frequency determined by device design (gate charge, capacitance Rds(on))
- Superior ruggedness under thermal cycling 
- Low-profile design for space-constrained systems 
- Enhanced power density without added complexity

**Cooler, Stronger, More Reliable** 

Heat is always the dreaded, silent killer in power electronics. MCC’s MCTT1D7N10Y in the TOLT package turns that challenge into an advantage. With topside cooling,  low RDS(on), and high current capability, this MOSFET empowers you to build compact, cooler-running, and power-dense systems that last. 

## Applications
