TVS (Transient Voltage Suppressor) diodes are a type of protection device utilized to safeguard downstream components from transients. Transients are inaccurate spikes of voltage caused by outside factors that can cause catastrophic harm to a system if left unprotected. The SMF7V5A-E3-18 is a uni-directional bidirectional TVS diode that, when connected between two power supplies, can shunt damaging transients away from sensitive electronics.The SMF7V5A-E3-18 TVS diode is designed to protect against overvoltage transients ranging from 5.5 to 18 volts. It has a peak surge capacity of 24A (8/20µs) and an ESD protection capacitance of 12pF. The diode also has a low breakdown voltage of 6V and a low clamping voltage of 18V (45A). This makes it well suited for low voltage applications such as computer motherboards, disk drives, electronic lighting, and other consumer electronic gadgets. Additionally, it is able to withstand the high surge currents of up to 50A (8.3ms).The working principle of the SMF7V5A-E3-18 is relatively simple. When correctly connected, the diode helps redirect transient voltage to ground.The diode acts by forming a conduction path for the transient current. This ensures that the transient current is diverted away from sensitive electronic components and towards the ground.In order for the SMF7V5A-E3-18 to be effective, it must be correctly placed within the power system it is protecting. The diode should be placed in series between the source of the transient and the ground devices. This allows the conductive path to work effectively and redirect the current. The diode should also be placed as close as possible to the component it is protecting, as this will reduce any inductive and capacitive effects that could reduce its effectiveness. The SMF7V5A-E3-18 offers excellent protection against high transient spikes by providing a low clamping voltage and low capacitance. With its low breakdown voltage and high surge capability, it can also act as a voltage limiter. This makes it well suited for use in consumer electronics, computer motherboards, and other sensitive electronic systems. The TVS diode is also available in alternate packages such as PowerDI®, SOD-323, and HSOP-4.To sum up, the SMF7V5A-E3-18 is an efficient uni-directional bidirectional TVS diode that is well suited for low voltage applications. With its low breakdown voltage, low clamping voltage, and high surge capacity, it is capable of protecting sensitive electronic components against damaging transient spikes. Additionally, it is also able to serve as a voltage limiter.
