TVS-Diodes are used in the semiconductor industry to protect fragile components from excessive current in the event of an electrical surge. The PGSMAJ78A R3G is a Transient Voltage Suppressor (TVS) that offers an ultra-high surge rated protection in a compact outline package and is widely used in applications to protect delicate electronics from voltage transients and electrical surges.

The PGSMAJ78A R3G is a unidirectional or bidirectional parallel diode, that able to protect against over-voltage transients in a wide range of applications. The device has a low leakage current (< 0.1µA ) and exhibits excellent dv/dt immunity (> 1000V/ns). The PGSMAJ78A R3G has a breakdown voltage of 78 Volts that allows it to handle high-ranked reverse transient overvoltage.

The PGSMAJ78A R3G can be used in various applications such as data and power line surge protection, Ethernet protection, LED lighting protection, audio video and telecom protection, automotive electronics protection, AC line surge protection, digital TV surge protection, fixed equipment surge protection, and AC motor surge protection.

The PGSMAJ78A R3G\'s working principle is based on a reverse breakdown characteristic that causes a rapid increase in current when the device is exposed to over-voltage which is greater than its rated breakdown voltage. This phenomenon converts the applied voltage to heat dissipating its excess energy, limiting the surge voltage to a safe level and protecting the circuit.

The PGSMAJ78A R3G is a reliable solution as it has a low clamping voltage, excellent clamping efficiency, fast response time, and excellent surge endurance characteristics. It is also reliable in harsh environments with high vibration, wide operating temperature range (-55°C to 175°C).

The PGSMAJ78A R3G is an excellent choice for protecting delicate electronics by limiting the surge voltage to a desired value, protecting the circuit from further damage. This device is widely used in various electronic circuits and offers a reliable and cost-effective solution for over-voltage protection.
