MQ1N8170US Circuit Protection

TVS Diodes have become an integral component in the design of modern electronics systems. The MQ1N8170US is a 6-pin, 3.3V surge protection TVS Diode designed to protect components in automotive body/ECU applications. Its ESD immunity is IEC 61000-4-2 level 4 Compliant.

The MQ1N8170US is an avalanche diode and it features a 6-pin SOT-23-5 package. As an avalanche diode, the device is designed to protect against electrical overstress from electrostatic discharge (ESD) and electrical transients. It has an operating forward voltage of 1.5V, a breakdown voltage of 4.2V, and an operating temperature range of -40°C to +125°C.

The working principle of the MQ1N8170US is as follows: in a stable state, the internal protection diode is forward biased, allowing current to flow freely. When a transient or ESD event occurs, the diode suddenly reverse-biases and allows the current to be drawn away from the circuitry, protecting it from damage. The device then quickly returns to its forward-biased state, providing uninterrupted protection to the circuit.

The MQ1N8170US is suitable for use in a variety of different applications, such as automotive body/ECU, automotive injector/solenoid, industrial control, telecom, consumer electronics, and medical devices. It offers an excellent leakage current level and fast response times, making it the perfect solution for these kinds of applications. In addition, it has a high surge current capability, providing superior protection against ESD and transient events.

In conclusion, the MQ1N8170US is an ideal protection device for protecting components from ESD and electrical transients. It features a 6-pin SOT-23-5 package, an operating forward voltage of 1.5V, a breakdown voltage of 4.2V, and an operating temperature range of -40°C to +125°C. It is suitable for use in a variety of different applications, such as automotive body/ECU, industrial control, telecom, consumer electronics, and medical devices.
