Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 400 W 2-Pin DO-214 SMAJ54CA R3

Taiwan Semiconductor SMAJ54CA R3 is a single-element bi-directional TVS (Transient Voltage Suppressor) diode designed for surface mount technology in a compact 2-pin DO-214 package. It offers a robust power dissipation of 400 W, making it effective in protecting sensitive electronic circuits from voltage spikes caused by transient surges and electrostatic discharge. This diode is engineered for industrial, consumer electronics, and communication equipment applications where voltage transient protection is critical.

The diode configuration is single-element bi-directional, providing symmetrical voltage suppression in both directions. It features a minimum breakdown voltage of 60 V and maximum reverse stand-off voltage of 54 V, ensuring swift clamping to a voltage of 87.1 V during surges. The peak pulse current rating stands at 4.6 A, allowing it to handle sudden high current transients.

Designed to operate in extreme environmental conditions, this diode functions reliably over a wide temperature range from -55°C to 150°C. Its small footprint (4.6 mm length, 2.83 mm width, 2.3 mm height) supports space-constrained PCB layouts without sacrificing performance. The maximum reverse leakage current is only 5 μA, minimizing power losses during normal operation.

This device includes ESD protection integrated to safeguard circuits from electrostatic discharge events. Although it does not comply with specific automotive standards, it is ideally suited for a wide range of applications in telecommunications, power supplies, industrial electronics, and consumer gadgets requiring transient voltage suppression. The SMAJ series from Taiwan Semiconductor is recognized for reliability and consistent performance.
