Product Description
Vishay SMAJ18CA-E3/61 is a high-performance 1-element bi-directional transient voltage suppressor (TVS) diode designed for surface mount applications. Housed in a DO-214 package, it offers a peak pulse power dissipation of 400 W, making it suitable for robust protection of electronic circuits against transient voltage spikes.
This TVS diode features a single-element, bi-directional configuration, providing symmetrical voltage protection. It has a minimum breakdown voltage of 20 V and a maximum reverse stand-off voltage of 18 V, protecting circuits by clamping transient voltages to a maximum of 29.2 V, ensuring safety and longevity of sensitive components.
The device operates reliably over a wide temperature range from -55°C to 150°C and complies with the automotive AEC-Q101 qualification, making it suitable for automotive and harsh industrial environments.
Compact dimensions of 4.5 mm length, 2.79 mm width, and 2.087 mm height allow for easy integration into modern PCB designs with only 2 pins for streamlined mounting. It also features effective electrostatic discharge (ESD) protection and a low maximum reverse leakage current of 1 μA to minimize power loss in steady-state conditions.
