Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 1.5 kW 2-Pin DO-214 SMCJ78CA

Taiwan Semiconductor SMCJ78CA is a high-performance 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed to protect electronic circuits from voltage transients and surges. It features a peak pulse power dissipation capability of 1.5 kW and is packaged in a compact 2-pin DO-214 surface mount configuration, making it ideal for integration on printed circuit boards.

This device is suited for industrial, consumer electronics, and telecommunications applications that require shielding from sudden voltage spikes. Its single-element bi-directional configuration effectively clamps voltage surges from either polarity, ensuring robust protection for sensitive semiconductor components.

The diode offers a minimum breakdown voltage of 86.7 V and a maximum reverse stand-off voltage of 78 V, ensuring precise triggering during transient events. It delivers a clamping voltage of 126 V to limit transient voltages to safe levels while supporting a peak pulse current of 11.9 A.

Designed to operate in extreme temperature environments between -55°C and 150°C, the SMCJ78CA provides reliability and longevity in harsh industrial and commercial settings. Its small form factor of 7.15 mm length, 6.25 mm width, and 2.75 mm height enables use in compact assemblies without compromising performance.

The device features a glass-passivated junction that minimizes leakage current, rated at a maximum of 5 μA, enhancing efficiency and stability in normal operation. Although it does not comply with automotive standards, it meets the FBI standard and UL94V-0 flammability rating, confirming its safety in various applications.

Typical use cases include power supply protection, data line safeguarding, and transient voltage suppression in telecommunications, industrial controls, and consumer electronics equipment. This TVS diode helps prevent damage to components by rapidly clamping and diverting transient voltages, thereby enhancing system reliability.

This 1-element bi-directional TVS Diode handles transients up to 1.5 kW with excellent clamping performance. Surface mount DO-214 package simplifies installation on PCBs in electronic and industrial devices. Operational temperature range from -55°C to 150°C supports harsh environment applications.

Robust glass-passivated junction technology ensures low leakage current and long-term stability. Certified to UL94V-0 flammability and FBI standards for electrical safety.
