TVS (transient protection devices) diodes provide high surge and transient protection in a robust, easy-to-use package. The SMF14A-HM3-08 TVS diode is a unidirectional, high-power transient- voltage-suppression (TVS) device that combines proven silicon-avalanche-technology with integrated protection circuitry to ensure optimum protection. It provides superior protection from electrical transients for systems� sensitive components.

When transient disturbances are applied, the diode switches into the avalanche mode breaking down the PN junction. This process typically lasts a few hundred nanoseconds, making the SMF14A-HM3-08 TVS diode ideal for high energy transient protection applications. It also offers an advantage in its ability to withstand extremely high current surges, up to 1,000 amps.

The SMF14A-HM3-08 TVS diode is designed for use in a wide range of consumer, industrial, telecommunications, automotive and other applications that require transient voltage protection. It provides an economic solution for protecting sensitive circuits from electrical transients caused by lightning, ESD, and other sources.

Applications of the SMF14A-HM3-08 TVS diode include:

• Car electronic devices (e.g. ECUs, electronic instrument clusters, and airbag systems)
• Telecommunications (e.g. cellular base stations and switching equipment)
• Data and signal line protection from lightning and ESD
• Consumer electronics, such as computers, home entertainment, and gaming systems
• Industrial controllers

The SMF14A-HM3-08 TVS diode is designed to provide protection from ESD, lightning-induced surge, as well as other high-voltage transients. It has an ultra-low rise time, high peak-pulse-current capability, and provides excellent clamping capability for high-speed data lines. The diode offers superior performance compared to traditional ceramic-based transient protection components, offering up to 20,000-V ESD protection.

The diode�s low capacitance and low clamping voltage make it well-suited for signal-line protection in applications involving high-speed serial data transfer up to 1.5 Gbps, such as RS-232, CAN-bus, CAN FD, USB, HDMI, DVI,Firewire, and others. The diode�s small size (SOD-323, SMA and mini-SMA package) makes it especially suitable for space-constrained designs.

The SMF14A-HM3-08 TVS diode is designed to protect electronic systems from a wide range of transient voltages from 40V to 14V, making it suitable for a wide range of applications. It is a bidirectional device, which can be connected in parallel to provide additional levels of transient protection. The device is also RoHS-compliant.
