TVS (Transient Voltage Suppression) diodes are semiconductor components that are highly effective at providing a one way path for surges of transient current at peak voltages. The SMCG5634E3/TR13 is a Surge Protection Diode application designed to protect consumer, industrial and automotive circuits from various transient surge events.

Application Field

The SMCG5634E3/TR13 is a 3.3 V logic drive, bidirectional voltage clamping device, well-suited for IEC-61000-4-5 lightning surge immunity in communications and non-communications circuits. This device features an ultra-low or nearly zero leakage current and low clamping voltage. This TVS Diode is ideal for protecting against Electrostatic Discharge (ESD) immunity up to 25 kV, Electrical Fast Transient (EFT) immunity up to 40 A, and surge immunity up to 8/20 μs pulse. It is suitable for protecting networking equipment, high-frequency RF devices, lines for set-top boxes, routers, switches, security systems, and automotive controllers.

Working Principle

TVS diodes work on the principle of voltage clamping, which is the process of controlling a transient voltage by keeping it within an acceptable voltage range for a given application. A voltage clamping TVS Diode is installed in parallel to a circuit to limit the current flowing through it in the case of a voltage spike or surge. The TVS Diode prevents unwanted voltage spikes or surges by clamping the voltage by dissipating and redirecting the power into the load which is connected to the diode.

The SMCG5634E3/TR13 can handle ESD, EFT and surge with respective peak pulse currents of up to 50 A, 25 A and 25 A. It is a bidirectional device, meaning that it protects against voltage transients from either direction, making it a more versatile choice than other options on the market. With its low profile (1.2mm) and wide variety of operating temperature ranges, the SMCG5634E3/TR13 is well-suited for any application.

TVS Diodes also provide valuable protection against Overvoltage (OV), which can happen if the incoming power exceeds its designed limits. OV can cause system crashes, data corruption and even damage to devices. The SMCG5634E3/TR13 is designed with a breakdown voltage of 8 V, meaning it will act as a clamp to any voltage exceeding 8 V, preventing the overvoltage from damaging the connected device.

In short, the SMCG5634E3/TR13 is an ideal TVS Diode choice for protecting against Electrostatic Discharge (ESD) immunity up to 25 kV, Electrical Fast Transient (EFT) immunity up to 40 A, and surge immunity up to 8/20 μs pulse. This device can be used in a wide range of applications such as networking equipment, high-frequency RF devices, lines for set-top boxes, routers, switches, security systems, and automotive controllers.
