Vishay Bi-Directional TVS Diode 3 kW Surface Mount DO-214AB Package SMC3K36CAHM3_A/H

Vishay SMC3K36CAHM3_A/H Bi-Directional TVS Diode is a transient voltage suppressor designed for protecting sensitive electronics against transient voltage spikes caused by inductive load switching and lightning. This device features a peak pulse power dissipation of 3 kW with a 10/1000 μs waveform, providing robust protection in a compact surface mount DO-214AB (SMC) package.

The diode operates in a bi-directional mode, suitable for protecting circuits where transient voltages can occur in both directions. It has a minimum breakdown voltage (Vbr) of 40 V and a maximum reverse stand-off voltage (Vwm) of 36 V, ensuring normal operation under these voltages with an effective clamping voltage of 58.1 V during transient events. The device can withstand a maximum peak pulse current (Ippm) of 51.6 A, making it capable of handling high surge currents typical in industrial, automotive, telecommunications, computer, and consumer electronics applications.

Designed to operate reliably within a temperature range from -55°C to 150°C, this TVS diode is qualified to the automotive standard AEC-Q101 and includes electrostatic discharge (ESD) protection. The product is compliant with RoHS, supporting modern environmental standards.

The small size and low incremental surge resistance offer excellent clamping capability and enable quick response times to transient voltages, protecting components like integrated circuits (ICs), MOSFETs, and sensor signal lines effectively. This device is not recommended for PCB bottom side wave soldering but meets MSL level 1 per J-STD-020 standard with a maximum lead-free peak solder temperature of 260 °C.

Its reliable performance makes it ideal for use in numerous industrial sectors such as automotive electronics, telecommunications, manufacturing equipment, and general industrial electronics where transients pose a significant risk.
