Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 600 W Surface Mount DO-214 SMBJ20CA

Taiwan Semiconductor SMBJ20CA is a 1-Element Bi-Directional Transient Voltage Suppressor (TVS) Diode designed for surface mount applications. It delivers a high peak pulse power dissipation of 600 W to protect delicate electronic components against transient voltage spikes.

This TVS Diode features a bi-directional diode configuration in a compact DO-214 package, making it suitable for bidirectional transient voltage protection applications. The device is ideal for safeguarding power lines and signal circuits in industrial, commercial, and electronics manufacturing environments.

The diode has a minimum breakdown voltage of 22.2 V and a maximum reverse stand-off voltage of 20 V, ensuring effective clamping action at 32.4 V. Its maximum peak pulse current capability is 18.5 A, suitable for handling high surge conditions. Operating temperature range from -55°C to 150°C permits use in diverse environmental conditions.

The SMBJ20CA employs a glass-passivated junction to guarantee fast response times and excellent clamping capabilities. Its compact dimensions (4.75 mm length, 3.95 mm width, and 2.45 mm height) enable efficient PCB mounting and space optimization. Although it does not meet automotive standards, it complies with FBI standards, ensuring quality and reliability in electronic circuit protection.

Typical applications include power management systems, industrial electronics, automotive electronics (non-automotive standard certified), and consumer electronic devices requiring robust transient voltage suppression.

The diode features a bi-directional configuration enhancing protection in both polarities. It offers a minimum breakdown voltage of 22.2 V and a clamping voltage of 32.4 V. The maximum reverse stand-off voltage is rated at 20 V for stable operation.

The diode is rated for a maximum peak pulse current of 18.5 A, ensuring reliable transient suppression. It operates reliably within a temperature range of -55°C to 150°C. Designed with a glass-passivated junction for improved reliability and fast response time.
