Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 600 W, 2-Pin DO-214 SMBJ12CA

Taiwan Semiconductor SMBJ12CA is a single-element bi-directional transient voltage suppression diode designed for protection against voltage spikes in electronic circuits. Featuring a 600 W peak pulse power dissipation capacity, this device is housed in a compact 2-pin DO-214 surface mount package, making it suitable for high-reliability applications in electronic, industrial, and communication equipment.

The diode supports a minimum breakdown voltage of 13.3 V and a maximum reverse stand-off voltage of 12 V, effectively clamping transient voltage surges to a maximum of 19.9 V. Its peak pulse current rating of 30.2 A ensures robust surge absorption capability. It operates safely within a temperature range from -55°C to 150°C, accommodating demanding environmental conditions. The glass-passivated junction structure provides enhanced reliability and longevity, while the compliance with FBI standards and UL94V-0 flammability rating attests to the safety certifications relevant in industrial and commercial environments.

Physical dimensions are 4.75 mm in length, 3.95 mm in width, and 2.45 mm in height, allowing for dense PCB layouts. This TVS Diode is ideal for circuit protection in power supplies, telecom devices, automotive systems without specific automotive certifications, and other industrial electronics requiring transient voltage suppression.
