TVS - Diodes

The Transient Voltage Suppression diode, commonly referred to as TVS diode, is a device that helps protect electronic components from overvoltage and electrostatic discharge (ESD). TVS diodes are designed to suppress ESD, transients, and other voltage stress conditions. The circuit containing the TVS diode is connected between the circuit elements to be protected and ground. TVS diodes can also be used as protection against overvoltage, lightning strikes, and other high energy events.

SLD30U-017-B application field and working principle

The SLD30U-017-B is a unidirectional bipolar diode with surge capability, designed for high current transient suppression in equipment vulnerable to voltage transients and electrostatic discharge (ESD). It is suitable for applications where EMI and RFI suppression is required. The SLD30U-017-B is a three-terminal device which is offered in a through-hole package. The maximum Ipp rating is 17A and its peak pulse power rating is 60V. The bipolar diode is rated for reverse working voltage of +15Vdc, a current of 10mA and a capacitance of 440pF.

The working principle of the SLD30U-017-B is simple. When a voltage transient occurs, the diode activates and clamps the voltage to a safe operating level. The device operates as a fast-acting "crowbar" that limits the voltage to a safe level. The device is designed to restrict the maximum voltage to a preset value and not to actuate until a given current is passed through it. The diode is characterized by its high surge capability, high drain current, and high surge energy absorption.

The SLD30U-017-B is used in applications where EMI and RFI suppression is required. It is used in automotive, subwoofer, and audio electronics, and as a transient protection for general DC/DC converters and power supplies. The device can be also be used in testing or emergency equipment which requires sustained transients. The SLD30U-017-B provides the increased clamping capability and surge degradation performance necessary to protect sensitive electronics.

The SLD30U-017-B is a high-power diode that is designed for high-current applications such as automotive and industrial inrush current protection, TVS protection, and high-power DC to DC converters. It is a unidirectional diode with low leakage current and fast response time. The diode is designed to suppress high-frequency voltage transients and pulses, while maintaining high power dissipation.

The SLD30U-017-B is a TVS diode which provides superior overvoltage protection to electronic components and circuitry. It has a high peak current capability and can withstand high power dissipation. Furthermore, the device has low leakage current and fast response time.
