SM15T30CAY Transil™ TVS Diode from STMicroelectronics

The SM15T30CAY is a state-of-the-art Transil™ transient voltage suppression (TVS) diode, designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This robust device is engineered to protect sensitive electronic equipment from voltage transients induced by system-induced surge events or external events such as lightning strikes.

Key Features

• Bi-directional surge protection: The SM15T30CAY provides symmetrical (bi-directional) transient voltage protection, making it suitable for AC line protection or applications where the polarity reverses.
• Stand-off voltage: It has a stand-off voltage of 30V, which ensures that it remains non-conductive under normal operating conditions and only activates when a transient voltage spike occurs.
• Peak pulse power: The device can handle peak pulse power dissipation of 1500 W (10/1000 μs), offering robust protection against high energy transients.
• High temperature stability: Constructed with high-temperature materials, the SM15T30CAY operates reliably over a wide temperature range, ensuring consistent performance under various environmental conditions.
• Package: The device comes in an SMB (DO-214AA) package, which provides a compact footprint and is suitable for high-density circuit board designs.
• Compliance: It meets the IEC 61000-4-2 and IEC 61000-4-5 surge immunity standards, and it is RoHS compliant, adhering to current environmental regulations.
