Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 400W 2-Pin DO-214 SMAJ20CA R3

Taiwan Semiconductor SMAJ20CA R3 is a 1-element bi-directional Transient Voltage Suppression (TVS) diode designed for protecting electronic components from voltage spikes and transient surges. With a peak pulse power dissipation rating of 400W, it provides robust clamp protection in a durable 2-pin DO-214 surface-mount package.

The diode configuration is single and bi-directional, supporting transient voltage suppression in both voltage polarities, making it well suited for protecting sensitive semiconductors and circuits from electrostatic discharge (ESD) and other transient events.

This model features a minimum breakdown voltage of 22.2V and a maximum reverse stand-off voltage of 20V, ensuring reliable operation under normal voltage conditions. Its clamping voltage is 32.4V, effectively limiting the voltage during surges to safe levels. The maximum peak pulse current is 12.3A, enabling it to handle significant transient current without damage.

The device operates over a wide temperature range from -55°C to +150°C, providing reliable performance in harsh industrial or automotive environments. Its compact physical dimensions (4.6mm length, 2.83mm width, 2.3mm height) allow easy integration in space-constrained PCB layouts.

The surface mount assembly type makes it ideal for automated manufacturing processes, improving production efficiency in electronics assembly lines. Its low reverse leakage current of 5μA ensures minimal power loss, enhancing energy efficiency in electronic designs.

Taiwan Semiconductor SMAJ20CA R3 is commonly employed in industrial, electronics manufacturing, automotive, and communication equipment to protect circuits from voltage transients, surges, and electrostatic discharge (ESD) events.
