STMicroelectronics SMBJ15CA-TR Transient Voltage Suppressor

The SMBJ15CA-TR from STMicroelectronics is a robust Transient Voltage Suppressor (TVS) diode, designed to protect sensitive electronics from voltage spikes and surges induced by lightning and other transient voltage events. This high-performance component is a go-to solution for safeguarding circuits in a variety of applications, ranging from consumer electronics to industrial systems.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 15V, which makes it suitable for protecting circuits that operate at or below this voltage level.
• Bidirectional Protection: As a bidirectional TVS, the SMBJ15CA-TR can protect circuits from surges occurring in both directions, making it versatile for AC applications or where the polarity may reverse.
• High Surge Capability: With its ability to handle surge currents up to 600W (10/1000μs), it can effectively clamp and withstand significant transient events, ensuring reliable protection for connected devices.
• Fast Response Time: The diode reacts in picoseconds to overvoltage events, providing immediate protection and minimizing the risk of damage to sensitive components.
• Low Clamping Voltage: The SMBJ15CA-TR has a low clamping voltage, which ensures that the voltage to which components are exposed during a surge is kept to a minimum, thus preserving the integrity of the protected device.
• Compact Package: Housed in a small SMB (DO-214AA) surface-mount package, it is ideal for high-density circuit board designs where space is at a premium.
