Driving records also implement the ADAS function, ADAS refers to the advanced driver assistance system, mainly through environmental perception, to predict the danger, and then to warn the driver. As a product on the car, it will be affected by a variety of surges in the car, especially in the case of throwing load, huge surge energy is easy to damage the car products, for the car surge SOCAY Electronics launched a car surge special protection device.
The device adopts patch package and is easy to produce. The pin adopts a large pad structure, which is conducive to the heat dissipation of the device, so its surge resistance is very strong. The power of the device itself can reach 6600W, and it can pass the ISO 7637-2:2004 standard, 24V system, 174V, and 4 euro surge grade。For ADAS protection, can pass the on-board surge test.

The operating voltage of the device is 33V, the clamping voltage is within 53.3V, and the operating voltage range is -55 ~ +175℃.

SM8E33A Transient suppression diode Features:
Working voltage V_R: 33V
Breakdown voltage V_BR@ (1mA) : 36.7V-40.6V
Clamp voltage V@ (150A) : 53.3V
Leakage current I_R@ (33V) : 5μA

Use in sensitive electronics protection against voltage transients induced by inductive load switching and lighting, especially for automotive load dump protection application.
