TVS – Diodes

TVS (Transient Voltage Suppression) diodes are components designed to protect other semiconductor devices from voltage transients such as electrostatic discharges (ESD), or other voltages that exceed the normal operating range. These devices are ideal for applications where the input or output signal levels may be exposed to large voltage changes in a short period of time.

TPD4E004DRYRG4 application field and working principle

The TPD4E004DRYRG4 is a 400V SMA (surface-mount) diode ideal for applications requiring a high-speed response. It is specifically designed to protect other components from transient voltage events. The device features an ESD rating of greater than 8kV (Human Body Model) and an operating temperature range of -55°C to +150°C. It has an average junction capacitance of 7.9pF and a reverse leakage current of 1.0µA at 4V.The working principle of the TPD4E004DRYRG4 is based on its ability to quickly absorb electrical disturbances within a certain range by relying on the “avalanche breakdown” mechanism. This mechanism works by allowing a large current to flow, while clamping the voltage to a safe level. It is important to remember that the device does not have an overvoltage protection function, so it is necessary to add an extra protection circuit.The application field of the TPD4E004DRYRG4 includes home and industrial power supplies, digital and communications equipment, automotive systems, consumer electronics, computer peripherals, and many other systems.

The TPD4E004DRYRG4 is also suitable for applications such as ESD and Lightning protection for DATA lines and Video lines, Automotive power and signal line protection, Cable protection and short-circuit protection in LiPo batteries. This device is also suitable for military standard applications.

The TPD4E004DRYRG4 is a great choice for applications that require a high-reliability, high-speed response. It is easy to mount and use, and is designed to protect sensitive devices from transient voltage events. With its high ESD rating and wide operating temperature range, the TPD4E004DRYRG4 is an ideal choice for many applications.
