The SM15T36CAY from STMicroelectronics is a robust transient voltage suppressor (TVS) designed to protect sensitive electronics from voltage spikes induced by voltage transients caused by lightning, load switch, and other disruptive events. This TVS diode is specifically engineered to safeguard circuits in a wide range of applications including automotive systems, industrial platforms, and consumer electronics.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 36V, making it suitable for a variety of operating conditions and ensuring that it remains non-conductive under normal voltage levels.
• Peak Pulse Power: With a peak pulse power dissipation of 1500W (10/1000µs), the SM15T36CAY can handle significant power surges, providing reliable protection against transient overvoltage events.
• Low Clamping Voltage: The low clamping voltage ensures that when the TVS is triggered, the voltage is clamped to a safe level, preventing damage to the protected components.
• High Temperature Stability: Built to withstand high temperatures, the SM15T36CAY operates effectively across a wide temperature range from -55°C to +150°C.
• Package: The device comes in a molded plastic over glass passivated junction in SMB (DO-214AA) package which offers a compact footprint and robustness for surface mount applications.
• Compliance: It is compliant with the following standards: ISO 7637-2 & 3 for automotive applications, IEC 61000-4-2 for ESD protection, and IEC 61000-4-5 for surge immunity.
