Taiwan Semiconductor 1-Element Uni-Directional TVS Diode, 1.5 kW, 2-Pin DO-214 SMCJ51A

Taiwan Semiconductor SMCJ51A is a 1-element uni-directional transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transients. It dissipates a peak pulse power of 1.5 kW, making it suitable for industrial and commercial applications requiring robust transient voltage protection.

Packaged in a compact DO-214 surface mount type, this TVS diode features a single diode configuration with a minimum breakdown voltage of 56.7 V and a maximum reverse stand-off voltage of 51 V, ensuring effective safeguarding of circuits against voltage stress. The device delivers a peak pulse current capacity of 18.2 A, allowing it to handle high surge currents commonly encountered in industrial environments.

The diode operates reliably across a wide temperature range from -55°C to 150°C, enabling deployment in harsh and demanding conditions. Its glass-passivated junction construction offers enhanced durability and stable electrical characteristics. The device also boasts low reverse leakage current (5 μA), minimizing power dissipation during normal operation.

Additional advantages include excellent clamping voltage performance with a rating of 82.4 V, fast response time to voltage transients, and a low incremental surge resistance which improves protection efficiency. The SMCJ51A is certified with UL94V-0 flammability classification and meets FBI standards, underscoring its compliance with safety and reliability requirements.
