Bourns, Inc. Diode, Full Reel; Product Range Bourns SMBJ28CA.

The Bourns SMBJ series diode, specifically part number 30AC0289, is a transient voltage suppressor (TVS) diode designed for surge and electrostatic discharge (ESD) protection. It features a bidirectional polarity with a reverse standoff voltage of 28V and a maximum clamping voltage of 45.4V. The diode is housed in a DO-214AA (SMB) case style and has two pins. This diode offers a minimum breakdown voltage of 31.1V and is compliant with RoHS standards. It is suitable for applications in portable communications, computing, and video equipment, where compact size and high performance are essential. The device is capable of handling a peak pulse power dissipation of 600 watts and a peak forward surge current of 100 amps. Its operating temperature range is from -55¬8C to +150¬8C, making it versatile for various environmental conditions. Engineers considering this diode for their projects should note its fast response times, which are less than 1.0 picosecond for unidirectional devices, ensuring effective protection against voltage transients.
