Surge protection diodes, commonly known as TVS (transient voltage suppressor) diodes, are used to protect electronic equipment from electrostatic discharge, lightning-induced transients, and slowly varying stress caused by surges. The SMF15CT1G is a TVS Diode designed for optimal and reliable surge protection. It provides cost-effective, high-performance protection against transients in automotive, consumer, industrial, medical, military, and telecommunications environments.

The SMF15CT1G is designed to protect sensitive circuitry from voltage spikes or transients caused by lightning, power supply surges, electrostatic discharge (ESD), or induced electrical noise. The device is a low-capacitance unidirectional diode with a 5.0 Volt breakdown voltage and a 1.5 Amperes peak current rating. It also offers low 2.0V turn-on voltage with AC performance, Reverse Stand-Off Voltage (Vrwm) of 13Volts, and RoHS compliance.

The device has an ultra-low dynamic resistance of 0.09 Ohms, which allows for very low voltage drops across its structure. This low resistance ensures that the device can handle high peak pulse currents without saturation. The device also features a low parasitic capacitance and inductance, allowing for ESD protection of up to 15KV and up to 40A peak pulse power handling capability.

The SMF15CT1G has been designed primarily for automotive, consumer, industrial, medical, military, and telecommunications usage. The device is ideal for use in ESD (electrostatic discharge) protection in automotive and industrial assemblies. It can also be used for EMI (electromagnetic interference) protection in consumer appliances and medical devices. Furthermore, the device can be used for EMC (electromagnetic compatibility) protection in industrial, medical, military, and telecommunications electronics.

The SMF15CT1G’s working principle involves the current flowing through the device in one direction only. When a transient voltage disturbance occurs, the device begins to conduct, creating a short circuit that quickly diverts the transient energy away from the circuitry. The device’s high peak current rating helps to ensure that the transient energy is dissipated quickly, preventing damage to connected components.

The device is designed to provide reliable and cost-effective surge protection in a wide range of operating environments, including automotive, consumer, industrial, medical, military, and telecommunications applications. The device is available in a variety of packages, allowing it to be used in a variety of board layouts and applications. With its high peak current rating, low parasitic capacitance and inductance, and RoHS compliance, the SMF15CT1G is ideal for surge protection in a variety of applications.
