The SMBJ70A-TR from STMicroelectronics is a robust transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage spikes and transients. This device is part of STMicroelectronics' SMBJ series, which is engineered to safeguard circuits against the damaging effects of voltage transients induced by inductive load switching and lightning disruptions.

Key Features

• High Surge Capability: With its ability to handle surges up to 600W (10/1000µs), the SMBJ70A-TR offers reliable protection for your circuits against high energy transients.
• Stand-off Voltage: The device has a stand-off voltage of 70V, which makes it suitable for a range of applications that operate under this voltage threshold.
• Uni-directional Functionality: As a uni-directional TVS diode, the SMBJ70A-TR is optimized for protecting circuits from positive voltage transients.
• Low Clamping Voltage: Upon encountering a voltage spike, the SMBJ70A-TR clamps to a low voltage, reducing the chance of damage to the protected component.
• Fast Response Time: The device reacts almost instantaneously (<1ps) to transient voltages, providing prompt protection when it is most needed.
• DO-214AA Package: Housed in a surface-mount DO-214AA (SMB) package, the SMBJ70A-TR is suitable for automated assembly and allows for efficient use of board space.
