Transient Voltage Suppressors (TVS) Diodes are used in many applications such as protecting delicate circuits and components from damaging electrical transients generated externally or internally. They are highly reliable surge protection devices that can safely divert and absorb large voltage transients that are produced by lightning and electrical switching and can protect power supplies, logic circuits, and data transmission lines. The ATV30C260JB-HF is a Transient Voltage Suppressor (TVS) Diode designed for protecting automotive components, specifically ECUs, against adverse electrical transients. It is an axial leaded two-terminal component packaged in an AEC-Q101 compliant and RoHS-compliant SOD-323F package.

The ATV30C260JB-HF has a 400 Watts maximum peak pulse power rating and operates over a -55°C to +150°C temperature range. It is designed for applications with an operating voltage range of 12V to 18V and has an 8V operating voltage. It is rated for working on both AC and DC circuits, and features transient protection on the anode side, reverse polarity protection, and an excellent capacitive response. The ultrashort recovery time helps ensure quick protection against transients and ensures comprehensive overvoltage protection for automotive ECUs.

The ATV30C260JB-HF is a MOSFET-equipped TVS Diode that works by sensing the surge voltage and switching on the MOSFET when the voltage threshold is exceeded. This triggers the TVS diode to clamp the voltage and protect the connected device from transient overvoltage. The diode is constructed with a glass passivated junction, along with a full glass body construction, which provides superior performance in harsh environments and excellent device life and reliability.

The ATV30C260JB-HF is designed to provide superior protection against fluctuations in the vehicle’s electrical system. It utilizes two elements for its protection; the breakdown voltage is determined by the MOSFET trigger voltage and the surge current by the silicon diode’s characteristics. The MOSFETs ability to be accurately triggered at low current levels and the fast response of the diode provide the user with excellent protection against electrical transients as quickly as possible.

The fast reaction time of the ATV30C260JB-HF makes it suitable for use in automotive ECUs, where fast protection against transients and surges is essential. The device also provides excellent protection against reverse polaritiy, which can damage sensitive components in automotive electronics. The 400 watt peak pulse power rating and the full glass body construction of the ATV30C260JB-HF make it an excellent choice for surge and transient protection in automotive electronics.
