Product Description
The onsemi SMCJ33CA is a single-element, bi-directional transient voltage suppression (TVS) diode intended to protect sensitive electronics from voltage spikes and electrostatic discharge (ESD). It is optimized for surface mount PCB applications in various industrial, automotive, and consumer electronic circuits requiring reliable transient voltage protection.
This TVS diode offers a peak pulse power dissipation rating of 1.5 kW, providing robust defense against high-energy transient surges. It features a minimum breakdown voltage of 36.7 volts and clamps voltage to a maximum of 53.3 volts during an event. The maximum reverse stand-off voltage is 33 volts, making it well suited for protecting low-voltage sensitive components.
The device is housed in a compact DO-214 package with dimensions of 7.15mm length, 6.25mm width, and 2.45mm height, facilitating easy integration into surface mount technology manufacturing processes. It operates reliably within a broad temperature range from -65°C to 150°C ensuring functionality in demanding environments.
Additional benefits include low incremental surge resistance, fast response time to voltage spikes, and a glass-passivated junction that improves long-term reliability. The diode supports electrostatic discharge protection with a maximum peak pulse current of 28.2 amperes and a test current of 1 mA.
This component is ideal for industrial power supply protection, automotive electronics, communications equipment, consumer devices, and other applications where safeguarding circuits from transient events is critical.
