The SM15T24AY is a high-performance transient voltage suppressor (TVS) diode designed by STMicroelectronics, a global leader in semiconductor solutions. This robust component is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system-level events such as load dump, lightning, and the switching of inductive loads.

Key Features

• Stand-off Voltage: The SM15T24AY has a stand-off voltage of 24V, making it suitable for a wide range of applications that require protection against high transient voltages.
• Peak Pulse Power Dissipation: With a peak pulse power dissipation of 1500W (10/1000μs surge), this TVS diode can handle significant power surges, ensuring the protection of the circuitry it is connected to.
• Clamping Voltage: It features a low clamping voltage, which is the maximum voltage the device will allow through after a surge event. This characteristic ensures minimal impact on the protected component after a voltage spike.
• Package: The SM15T24AY comes in a molded plastic over glass passivated junction in a DO-214AB (SMC) package. This package offers a compact footprint and is suitable for high-density circuit board designs.
• Compliance: It complies with IEC 61000-4-2 and IEC 61000-4-4 standards, which are related to electrostatic discharge (ESD) and electrical fast transient (EFT) immunity, respectively.
• Operating Temperature Range: The device operates effectively over a wide temperature range from -55°C to +150°C, accommodating various environmental conditions.
