HV automotive photorelay targets vehicle battery management systems
The new TLX9160T consists of an infrared emitting diode optically coupled to a photo-MOSFET and is Toshiba’s first device with a high output withstand voltage (VOFF) of at least 1500V. The device is capable of operating from a supply voltage (VDD) of up to 1000V, ensuring that it is compatible with the vast majority of traction batteries.
Housed in a modified SO16L-T package that is made from a resin material in IEC60664-1 material group I, which has a Comparative Tracking Index (CTI) exceeding 600, the TLX9160T has four fewer pins (pins 11 to 14 are removed from the standard SO16L package). The product features a creepage distance of at least 5mm at its detector, ensuring that it is compatible with supply voltages up to 1000V – as defined by IEC60664-1. As a result, the isolation voltage (BVS) is 5000Vrms (min.) and internal creepage and clearance distances are 8mm.
The maximum forward current (IF) is 30mA while the On-state current (ION) is 50mA with an Off-state current (IOFF) of just 100nA. Suitable for the rugged automotive environment, the device is fully AEC-Q101 qualified with an operating temperature from -40°C to +125°C.
The device is available for shipping.
