| LF New Fast-Switching Teccor Thyristors |
Thursday, April 17, 2008
Des Plaines, IL, April 16, 2008 – Littelfuse, Inc. (NASDAQ/NGS:LFUS) today introduced the EV Series - Enhanced Version Teccor brand Thyristors. These thyristors feature a minimum rated blocking voltage (Vdrm/Vrrm) of up to 800 V, a maximum turn-on time (tq) as low as 25 µs, and a minimum rated static dv/dt of up to 75 V/µs – a five times improvement over earlier thyristors of this type.
The high blocking voltage and dv/dt immunity are attractive to designers creating circuits for high-stress and/or high-reliability applications. These features help a triac to better survive transient voltages, minimize false triggering, and prevent unstable activation. For example, one of the more common failure mechanisms in thyristors is a permanent short caused by a transient that exceeds the dv/dt rating.
In addition to being more robust, this feature helps prevent excess energy from being passed to the circuit or load being protected. Fast turn-on time is important in applications such as ground fault circuit interruption, where it helps ensure proper operation of the associated electromechanical breaker.
The new EV Series of thyristors includes four families:
The SxX8xSx EV family of 0.8 amp sensitive gate SCRs
The Sx02xS EV family of 1.5 amp sensitive gate SCRs
The LX8 EV family of 0.8 amp sensitive gate triacs
The L01 EV family of 1.0 amp sensitive gate triacs
