Product Description
Taiwan Semiconductor SMCJ33CA is a high-performance 1-Element Bi-Directional Transient Voltage Suppressor with a power rating of 1500 W, packaged in a compact 2-pin DO-214AB (SMC) surface mount package. Designed to safeguard electronic circuits from voltage transients caused by inductive load switching and lightning, this device offers reliable protection for sensitive components in industrial, automotive, manufacturing, and consumer electronics applications.
The device features a single diode configuration, providing bi-directional clamping action that efficiently suppresses voltage spikes in both polarities. It has a minimum breakdown voltage (Vbr) of 36.7 V and a clamping voltage (VC) of 53.3 V to limit the voltage to safe levels during transient events. The peak pulse power dissipation capability of 1500 W with a 10/1000 µs waveform and the maximum peak pulse current (Ippm) of 29 A ensure robust transient protection under high-energy surges.
Constructed with a glass passivated junction and built-in strain relief, the SMCJ33CA provides excellent durability and long-term reliability. It operates in a wide temperature range from -55°C to 150°C, accommodating harsh environments and diverse industrial conditions. The compact dimensions of length 7.11 mm, width 6.22 mm, and height 2.62 mm make it suitable for high-density PCB layouts.
This transient voltage suppressor complies with UL 94V-0 flammability rating and RoHS regulations, representing safe and environmentally-friendly design. The low leakage current (maximum of 1 µA) minimizes energy loss during normal operation. It is an ideal choice for protecting power supplies, communication systems, and consumer electronics from damaging voltage spikes.
Package contains the Taiwan Semiconductor SMCJ33CA device, ready for surface mount integration into various electronic assemblies. This product is sourced from China and is supplied in a reel for automated assembly efficiency.
Single diode, bi-directional transient voltage suppression for dual polarity protection. High peak pulse power capability of 1500 W offers robust surge handling. Compact DO-214AB package saves PCB space. Wide operating temperature range from -55°C to 150°C suits industrial applications.
Built-in strain relief and glass passivation enhance durability. Meets UL 94V-0 and RoHS standards for safety and compliance. Low leakage current improves efficiency during normal operation. Perfect for automotive, industrial, and consumer electronic transient protection.
