600V CoolMOS S7 family expanded with MOSFETs
Summary
The CoolMOS S7 10mΩ has a unique low on-resistance (R DS(on)) for 600V superjunction MOSFETs, making it ideal for applications where minimal conduction losses are critical, such as off-the-shelf solid-state relays (SSR). In contrast, the automotive-grade CoolMOS S7A addresses system performance requirements set by solid-state circuit breakers (SSCB) and diode paralleling/replacement for high power/performance designs in automotive applications, such as the High Voltage (HV) eFUSE, HV eDisconnect battery disconnect switch, as well as on-board chargers. As a result, the new devices can offer the price-performance ratio at the high quality standards, placing even greater emphasis on conduction performance, energy efficiency, power density, and improved thermal resistance. Additionally, they have been integrated into an innovative top-side cooled (TSC) QDPAK SMD package, which offers excellent thermal behaviour, making it a smaller alternative to THD devices such as TO-247. Moreover, with moving from THD to a surface-mounted device with QDPAK, a 94% reduction of height can be achieved, enabling higher power density solutions.
