The SMBJ28CA-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage transients induced by system inductance or lightning. This TVS diode is particularly suitable for the protection of voltage-sensitive devices in a wide array of applications including industrial, commercial, and consumer markets.

Key Features

• Stand-off Voltage: The SMBJ28CA-TR has a stand-off voltage of 28V, which makes it ideal for protecting circuits with a working voltage around this level.
• Peak Pulse Power: It can handle a peak pulse power of 600W (10/1000μs), providing a high degree of protection against transient voltage spikes.
• Bi-directional Protection: As a bi-directional TVS, the SMBJ28CA-TR can protect circuits from voltage spikes occurring in both directions along the signal or power line.
• Low Clamping Voltage: The device has a low clamping voltage, ensuring that the voltage spike is kept to a minimum, thus protecting sensitive components from overvoltage.
• Fast Response Time: The TVS diode reacts in picoseconds to voltage transients, providing immediate protection against surge events.
• DO-214AA Package: The SMBJ28CA-TR comes in the popular DO-214AA (SMB) surface-mount package, which is suitable for high-volume production and is easy to integrate into various PCB designs.
