Toshiba Released High Voltage 1500 Automotive Photorelay

The new device is suitable for high voltage automotive batteries


Kawasaki, Japan : Toshiba Electronic Devices and Storage Corporation has launched the “ TLX9160T ” which is a normally open (NO) 1-Form-A photorelay suitable for high voltage automotive batteries. Encased in a SO16L-T package, this new device is Toshiba’s first device to feature a high output resistance voltage of 1500V (Min). Its bulk dispatch is starting from today.

Incorporation of a high voltage MOSFET (MOSEFT) into the new device achieves an output resistance voltage of 1500V (Min). One SO16L-T package made of resins in IEC 60664-1 International Standard Materials Group I [1] , with more than 600 CTI[2] and four firer pins (pins 11 to 14 have been omitted from current SO16L packages) When engaged, the instrument achieves creepage of 5 mm or more [3] upon detection. This ensures support for 1000V supply voltage under IEC 60664-1, suitable for photorelays for high voltage automotive applications with battery voltages up to 1000V.

[1] CTI [2] Groups molded goods by value to IEC 60664-1: CTI 600
[2] Comparative Tracking Index: IEC 60112 defines CTI as the first maximum possible voltage drop of ammonium chloride solution on the surface of the insulating material under the current test conditions.
[3] @Working Wootage = 1000V, Substance Group I, Pollution Level 2 (Pollution level of the operating environment where electrical equipment is used; pollutants are completely non-conducting, but likely to conduct by condensation Huh.)
