The SMBJ40A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode, specifically designed to protect sensitive electronic equipment from voltage spikes and transient voltage events. This TVS diode is a member of the SMBJ series, housed in a compact DO-214AA (SMB) surface-mount package, making it suitable for high-density circuit board designs.

Product Features:

• Stand-off Voltage: The SMBJ40A-TR has a stand-off voltage of 40V, which is the maximum voltage that can be applied over the TVS diode without causing it to conduct in avalanche mode.
• Peak Pulse Power: It offers a peak pulse power dissipation of 600W for a 10/1000μs waveform, ensuring protection against high energy transients.
• Clamping Voltage: Upon encountering a voltage surge, the clamping voltage of this device activates, capping the voltage to a safe level of approximately 64.5V at 10A, protecting downstream components.
• Low Leakage Current: With a low leakage current under normal operating conditions, the SMBJ40A-TR ensures minimal impact on the overall power consumption of the system.
• Fast Response Time: The TVS diode reacts almost instantaneously (<1ps) to transient over-voltages, providing immediate protection to the circuitry.

Applications:

The SMBJ40A-TR is versatile and can be used in a wide range of applications, including:

• Industrial systems
• Consumer electronics
• Communication systems
• Automotive electronics
• Power supply protection
