The SM15T82CAY is a robust and reliable transient voltage suppressor (TVS) diode designed and manufactured by STMicroelectronics, a global semiconductor leader known for its cutting-edge technology and high-quality electronic components. This component is specifically engineered to protect sensitive electronic equipment from voltage spikes and surges, making it an essential part of any circuit where transient overvoltage protection is required.

Key Features

• Stand-Off Voltage: The device has a stand-off voltage of 82V, which refers to the maximum voltage that can be applied to the TVS diode without causing it to conduct significantly.
• Peak Pulse Power: It offers a peak pulse power dissipation of 1500W (10/1000µs), ensuring effective protection against high-energy transients.
• Breakdown Voltage: The breakdown voltage range is specified with a minimum of 91.1V and a maximum of 100.9V, providing a precise protection window for your circuits.
• Low Clamping Voltage: Upon triggering, the SM15T82CAY clamps the overvoltage to a safe level, thereby protecting the downstream components from damage.
• Package: The device is available in a molded plastic, over glass passivated junction, SMB (DO-214AA) package, which offers a compact footprint and is suitable for high-volume production.
• Compliance: It complies with the following standards: IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge), ensuring compatibility with the most stringent industry requirements.
• Operating Temperature Range: The operating junction temperature range is from -55°C to +150°C, allowing the device to function reliably in a wide range of environmental conditions.
