Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 400W, 2-Pin DO-214 SMAJ48CA R3

Taiwan Semiconductor SMAJ48CA R3 1-Element Bi-Directional TVS Diode offers robust transient voltage suppression rated at 400 watts peak pulse power, housed in a compact 2-pin DO-214 surface mount package. This diode is designed for stability and protection in sensitive electronic circuits, providing effective voltage clamping in industrial, electronic components, and power management applications.

Its bi-directional configuration allows it to protect circuits against both positive and negative transient voltage surges, making it useful for automotive electronics, industrial systems, and consumer electronic devices where voltage spikes are common hazards. The device operates reliably under a broad temperature range from -55°C to 150°C, suitable for harsh environments.

With a minimum breakdown voltage of 53.3 volts and clamping voltage of 77.4 volts, it ensures fast response and limits voltage spikes to safe levels. The maximum peak pulse current capacity of 5.2 amperes and maximum reverse leakage current of just 5 microamperes make this diode highly efficient in transient voltage suppression while minimizing power loss.

Measuring 4.6mm in length, 2.83mm in width, and 2.3mm in height, the compact DO-214 package is ideal for automated PCB assembly and space-constrained circuit designs. The device is part of the SMAJ series, known for durable and reliable performance in transient voltage suppression.
