The SM4T26CAY from STMicroelectronics is a robust Transil™ diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. This high-performance TVS (Transient Voltage Suppressor) is specifically engineered to safeguard voltage-sensitive components from destruction or degradation, ensuring reliability and longevity in a variety of applications.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 26V, making it suitable for a range of applications where this level of protection is required.
• Peak Pulse Power: It can handle a peak pulse power of 400W (10/1000 µs), providing effective protection against high energy transients.
• Low Clamping Voltage: The low clamping voltage ensures that the protected component is exposed to a minimal voltage during a transient event, thereby reducing the risk of damage.
• Fast Response Time: The diode's fast response time ensures that it reacts almost instantaneously to transient events, offering immediate protection to the circuit.
• Low Leakage Current: With its low leakage current, the SM4T26CAY minimizes power loss and maintains efficiency in the circuit.
• Unidirectional Device: This unidirectional TVS diode is specifically designed to protect one polarity over the other, making it ideal for DC voltage applications.
