A TVS diode is a three-terminal semiconductor device that provides protection from transient voltage surges.The GL24T-HE3-18 is a unidirectional, low capacitance, TVS diode specifically designed for high-speed data lines and automotive applications. It is manufactured by Gennum Corporation and is a member of their GuardChip family of products.

The GL24T-HE3-18 is designed to provide robust overvoltage protection in automotive, telecom and industrial applications. The device protects motor control circuit, communication equipment, and other equipment from damages caused by transient voltage and/or currents. It is designed to protect high speed data board traces from transients induced by either ESD or EFT events. The device is housed in a small & thin SOT-23 RoHS (Green) compliant package, making it ideal for automotive applications.

The GL24T-HE3-18 TVS diode consists of two Schottky diodes and a Zener diode connected in a back-to-back configuration. This configuration allows the device to provide transient protection at both low and high clamping voltages over multiple current ranges for different types of transient events. In addition, the device features low capacitance and switching time of just 14ps, making it an ideal choice for high speed data lines.

The GL24T-HE3-18 is designed to operate in the -55C to 125C temperature range and is resistant to ESD pulses up to ±30kV contact discharge, making it suitable for applications in automotive as well as industrial environments. The device has a breakdown voltage of 18V and an operating voltage of 16.5V. It can dissipate a maximum breakdown surge current of 9A and clamping voltage of 32V.

The GL24T-HE3-18 TVS diode is designed to protect high speed data lines, automotive electronics, and other sensitive components from transient overvoltages. The device can clamp voltages up to maximum breakdown voltage and can dissipate high surge current. Its low capacitance and fast switching time makes it ideal for high speed data lines and automotive applications. It is also highly resistant to ESD pulses and can operate in temperatures ranging from -55C to 125C.
