STMicroelectronics 1-Element Uni-Directional TVS Diode, 1.5 kW, 2-Pin SMC Package SMCJ22A-TR

STMicroelectronics SMCJ22A-TR is a high-performance 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes and transient surges. With a peak pulse power dissipation capability of 1.5 kW, this device effectively clamps high transient voltages, safeguarding circuits in critical applications.

This TVS diode is provided in a standard 2-pin Surface Mount Device (SMD) SMC package, suitable for automated PCB assembly processes. The uni-directional configuration allows it to protect against positive polarity voltage transients.

Its electrical characteristics include a minimum breakdown voltage (Vbr) of 24.4 V, a maximum reverse standoff voltage (Vwm) of 22 V, and a clamping voltage (Vc) of 48.3 V, making it ideal for protecting circuits operating in this voltage range. Withstanding a wide operating temperature range from -55°C up to 150°C, it provides reliable performance in industrial, automotive, and commercial environments.

The diode features a maximum peak pulse current (Ippm) of 207 A and test current of 1 mA, ensuring effective transient event suppression. The device exhibits very low reverse leakage current (1 μA max), contributing to minimal leakage and enhanced circuit efficiency.

Compact physical dimensions of 7.15 mm in length, 6.25 mm in width, and 2.45 mm in height facilitate easy integration in space-constrained applications.

This component is suitable for protection in electronic, power, and communication circuits where transient voltage spikes could cause damage. Common use cases include industrial automation systems, power supplies, telecommunication devices, and automotive electronics.
