SMCJ22A-TR Transient Voltage Suppressor by STMicroelectronics

The SMCJ22A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This high-performance device is specifically engineered to safeguard voltage-sensitive components which can be damaged or disrupted by these types of sudden voltage spikes.

Key Features

• Stand-off Voltage: The SMCJ22A-TR has a stand-off voltage of 22 volts, which is the maximum reverse voltage that can be applied without causing any significant current flow.
• Peak Pulse Power: It can handle a peak pulse power of 1500 Watts at 10/1000 microseconds, ensuring effective protection against high energy transients.
• Clamping Voltage: With a clamping voltage of 35.5 volts, this device can clamp the overvoltage to a safe level, preventing potential damage to the circuit.
• Uni-directional: As a uni-directional TVS, the SMCJ22A-TR is specifically designed to provide protection in one direction, making it ideal for DC voltage applications.
• Low Leakage Current: It features a low leakage current, minimizing any power loss when the device is in the stand-by mode.
• ISO 9001 and ISO 14001 Certified: Manufactured by STMicroelectronics, a leader in the semiconductor industry, ensuring high-quality standards and environmental management.
