onsemi 1-Element Bi-Directional TVS Diode 1.5 kW, Surface Mount DO-214 Package SMCJ33CA

onsemi SMCJ33CA is a high-performance 1-Element Bi-Directional Transient Voltage Suppressor (TVS) Diode, designed for surface mount applications requiring superior transient voltage protection in electronic circuits. This device offers a peak pulse power dissipation rating of 1.5 kW, making it ideal for protecting sensitive components from voltage spikes, surges, and ESD events in various industrial, commercial, and consumer electronics.

The diode configuration is bidirectional and single-element, delivering symmetrical clamping to safeguard against voltage transients in both forward and reverse directions. With a minimal breakdown voltage of 36.7 V and a maximum reverse standoff voltage of 33 V, the SMCJ33CA provides precise voltage regulation. It features a clamping voltage of 53.3 V and supports a maximum peak pulse current of 28.2 A during surge conditions.

The device is housed in a compact DO-214 package, with dimensions measuring 7.15 mm in length, 6.25 mm in width, and 2.45 mm in height, enabling efficient PCB layout and integration. Its operational temperature spectrum ranging from -65°C to 150°C ensures reliable performance in demanding environments such as automotive electronics, industrial automation, and power supplies.

ESD protection capabilities add an additional safeguarding layer against electrostatic discharge. The maximum reverse leakage current is limited to 1 μA, helping maintain low power dissipation during standby or normal operations.

Typical applications include surge protection in power supplies, telecommunication lines, automotive systems, and semiconductors requiring robust transient voltage mitigation. Bidirectional diode configuration provides symmetrical voltage protection.
