The Automotive-grade Transient Voltage Suppression Diode SM8S33A is Used for Surge Protection of Vehicle
Car GPS locator, we can also call it a car position tracker. It has a terminal with built-in GPS module and mobile communication module, which is used to transmit the positioning data obtained by the GPS module to a server on the Internet through the mobile communication module, so that the terminal location can be queried on the computer. However, when a car is driving, transient phenomena such as power supply and load disconnection or sudden interruption of current often occur, causing abnormal high voltage in the circuit and causing damage to the on-board GPS locator on the car.
In order to better protect the vehicle-mounted GPS locator on the car from the impact of surges, SOCAY Electronics （www.socay.com）recommends SM8S33A, which is designed for vehicle-mounted surge protection of the vehicle-mounted GPS locator of the 24V system. The device adopts DO-218AB patch package, which is beneficial to the protection effect. Provides one-way protection, has low leakage current and low forward voltage drop, and has fast response time, usually less than 1PS. It complies with AEC-Q101 automotive standards and can pass ISO7637-2 (5a) automotive load dump test 174V, 350ms, 4Ω surge level test.
The device operates with a voltage of 33V and a maximum power of 6600W.
It has strong high temperature resistance and the working temperature range is -55℃~﹢175℃.
Typical parameters of SM8S33A TVS diode:
Off-state voltage VR: 33V
Leakage current IR: 150μA
Breakdown voltage VBR: 36.7~40.6V
Clamping voltage VC (at IPP=124A): 53.3V
Maximum power Ppp: 6600W
Applications of SM8S33A Automotive-grade Transient Voltage Suppression Diode:
Car GPS locator
car charger
driving recorder
car atmosphere light
Car audio and video
