India, April 28 -- Toshiba Electronic Devices & Storage Corp. has launched a photovoltaic-output photocoupler, "TLX9920", in a thin, long-creepage-distance SO6L package, for solid state relays (SSR) in automotive equipment. Volume shipments start now.

Demand is growing for automotive equipment relay units with a longer life, a trend that has led to increased use of SSR instead of mechanical relays. As automotive systems continue to evolve, the shift to SSR is expected to accelerate further.

TLX9920 is suitable for use as a gate driver for the high-voltage power MOSFET used in SSR. Combined with a high-voltage power MOSFET, it can achieve high-voltage and high-current switching that is difficult with photorelays. As SSR have no physical ...
