SMBJ15A-TR

The SMBJ15A-TR is a transient voltage suppressor (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients and electrostatic discharge (ESD) events.

Description:

The SMBJ15A-TR is a high-speed, bidirectional TVS diode that provides excellent protection against high-energy transients and ESD events. It is available in a DO-214AA surface-mount package, which is compact and easy to integrate into a wide range of electronic devices.

Features:

1. Bidirectional protection: The SMBJ15A-TR provides protection in both the forward and reverse directions, making it suitable for applications where the polarity of the transient voltage is unknown or variable.
2. High surge current capability: The device can handle high-energy transients and surge currents, making it suitable for protecting power lines and other critical circuits.
3. Low clamping voltage: The SMBJ15A-TR has a low clamping voltage, which means it can quickly respond to transient voltages and limit the voltage across the protected circuit to a safe level.
4. High reliability: The device is designed for high reliability and long-term stability, making it suitable for use in demanding applications where reliability is critical.
5. Compact package: The DO-214AA surface-mount package is compact and easy to integrate into a wide range of electronic devices.
