Ultra miniature IGBTs/MOSFETs
In December 2011, Toshiba Electronics Europe (TEE) launched two ultra miniature IGBT/MOSFET gate drive photocouplers.
Features and USP: The TLP700H and TLP701H are supplied in SDIP6 packaging and are designed to directly drive IGBTs and power MOSFETs without the need for additional components. Maximum peak output current ratings are ±2.0 A for the TLP700H and ±0.6 A for the TLP701H. Despite their size (the mounting area is just half that of a DIP8 package), each device has a minimum withstand voltage of 5000 Vrms.

Super junction MOSFETs
In April 2012, Infineon Technologies launched its 650V super-junction MOSFET device—CoolMOS CFDA.
Features and USP: The 650V CoolMOS CFDA has been specifically designed for resonant topologies such as battery charging, DC/DC converters and HID (High Intensity Discharge) lighting, and also for hybrid and electric vehicles. Some of its features include better light load efficiency, reduced gate charge, lower switching losses, easy implementation as well as outstanding reliability. The CoolMOS CFDA provides lower area specific on-resistance while offering easy control of switching behavior, as well as the highest body diode ruggedness in the market.

Disconnect relays
In April 2012, Johnson Electric launched a disconnect relay product line for smart electric meters.
Features and USP: The Ledex-EM product line is a bi-stable latching relay designed to provide the highest electrical performance in a compact package. The product line provides industry leading switching performance and reliability, resulting from a unique design that minimises contact bounce and resistance. This disconnect relay has the highest magnetic tamper resistance in any position, preventing switching by an external magnetic field. It is designed with a circuit breaking capacity of up to 120 amps.
