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^[1], which has CTI^[2] exceeding 600 and four fewer pins (pins from 11 to 14 are removed from existing SO16L package), realizes creepage of 5mm or more^[3]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.

Notes:
[1] IEC 60664-1 groups molded materials according to CTI^[2]value.: CTI 600
[2] 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.
[3] @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.)
