New device is suited for high voltage automotive batteries
KAWASAKI, Japan— Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched “TLX9160T,” a normally open (NO) 1-Form-A photorelay suited for high voltage automotive batteries. Housed in an SO16L-T package, the new device is Toshiba’s first to feature a high output withstand voltage of 1500V (min). Volume shipments start today.
Incorporation of high voltage MOSFETs in the new device achieves an output withstand voltage of 1500V (min). An SO16L-T package made of a resin in the IEC 60664-1 international standard material group I, which has CTI exceeding 600 and four fewer pins (pins from 11 to 14 are removed from existing SO16L package), realizes creepage of 5mm or more at the device’s detector. This ensures support for 1000V supply voltage under IEC 60664‐1, suiting the photorelay for high voltage automotive applications with a battery voltage of up to 1000V.
 IEC 60664-1 groups molded materials according to CTI value.: CTI 600
 Comparative Tracking Index: IEC 60112 defines CTI as the maximum possible voltage before droplets of ammonium chloride solution on the surface of the insulating material cause tracking, under the given test conditions.
 @Working voltage=1000V, material group I, pollution degree 2 (the degree of pollution of the operating environment where electrical equipment is used; pollutants are entirely non-conductive, but could potentially be rendered conductive by condensation.)
