STMicroelectronics 1-Element Bi-Directional TVS Diode 600 W, 2-Pin DO-214 SMBJ8.5CA-TR

STMicroelectronics SMBJ8.5CA-TR is a single-element bi-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from transient voltage spikes and surges. It is engineered to safely absorb and clamp voltage transients up to 600 W of peak pulse power in a compact DO-214 surface mount package.

This diode features a bi-directional configuration allowing for protection in both directions, making it suitable for a wide range of applications in electronic circuits requiring surge protection. The device exhibits a minimum breakdown voltage of 9.4 V and a maximum reverse stand-off voltage of 8.5 V, which ensures effective suppression while maintaining normal circuit operation.

With a peak pulse current rating of 205 A and a clamping voltage of 19.5 V, the SMBJ8.5CA-TR provides robust safeguarding against voltage transients typically caused by inductive load switching, lightning surges, and electrostatic discharge. Its low maximum reverse leakage current of 20 μA helps minimize unwanted power loss during standard operation.

The diode is rated for a broad operating temperature range from -55°C to 150°C, ensuring reliable performance in diverse industrial, electronic manufacturing, automotive, and telecommunications environments. The physical dimensions are compact, measuring 4.6 mm in length, 3.95 mm in width, and 2.45 mm in height, facilitating easy integration into densely packed circuit boards.

This SMBJ series TVS diode is ideal for transient voltage suppression applications requiring high pulse power capability and reliable bi-directional protection. Its surface mount DO-214 form factor optimizes automated assembly and maximizes space efficiency on printed circuit boards.
