Transient voltage suppressors (TVS) are an indispensable part of modern devices, safeguarding sensitive components from tripping due to a surge in voltage. IXBOD1-38R, a non-linear TVS device made up of mixed technologies, is one of the most commonly used TVS’s. This article explains the working principle and applications of this device in a comprehensive manner.

An IXBOD1-38R TVS contains a multilayer ceramic chip capacitor (MLCC), a fast recovery diode, and a diode array. While the MLCC provides dc blocking capabilitiy, the diodes and the diode array provide clamping. This device also has a robust construction to withstand high energy transients. The IXBOD1-38R has a fast response time (1 nsec) and offers a Rated Standoff Voltage of 6V to 48V, and a Maximum Clamping Voltage of 15V to 78V.

This TVS is mainly used for protecting high-speed, I/O signals which are particularly vulnerable to transients. This device can also be used for protecting high-speed data lines which experience severe transients. The IXBOD1-38R also offers good protection for automotive AC lines, lines connected to switching DC-DC converters, and lines connected to AC/DC adapters. It also provides ESD protection as it can withstand up to 8kV air-gap discharge and 15kV contact discharge.

This device can be used in a variety of applications including mobile phones, digital cameras, and other consumer electronics. It is best suited for applications that require high speed data transmission, due to its fast response time. The IXBOD1-38R also offers excellent protection against lightning and electrostatic discharges.

In Measuring Mode, the IXBOD1-38R can measure current and voltage. It also has an Over-voltage Protection (OVP) feature which detects when the voltage exceeds the set limit, and shuts off the power supply to protect the connected equipment.

The operating principle of the IXBOD1-38R can be simply explained in three stages. In the first stage, the diode array sends the voltage to a filtering MLCC. The MLCC helps to ensure that the voltage is constant and within the acceptable limits. In the second stage, the diode array absorbs the excess energy during over voltages. This prevents the connected components from damage due to an over voltage. In the third stage, the fast recovery diode quickly switches off the power supply when the voltage exceeds the set maximum limit.

Overall, the IXBOD1-38R is an excellent choice for high-speed and high-voltage applications. This device not only offers good protection, but also provides an Over-voltage Protection (OVP) feature. It is capable of withstanding high energy transients and its fast response time makes it ideal for applications that require high speed data transmission.
