The SM15T18A is a unidirectional TVS (transient voltage suppression) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, ESD, and other surge events. The device offers a reverse standoff voltage of 15.3V and a maximum clamping voltage of 32.5V at a peak pulse current of 308A (8/20µs waveform). With a peak pulse power rating of 1500W, it can handle high-energy transients. The SM15T18A is a single-channel unidirectional device, making it suitable for applications where only one polarity protection is needed. It is not intended for power line protection, as indicated by the 'No' value for power line protection. The operating temperature range is -55°C to 150°C, allowing use in harsh environments. The device is housed in a DO-214AB (SMC) surface-mount package, which is compact and suitable for automated assembly. It is classified as a general-purpose TVS diode, suitable for a wide range of electronic equipment requiring transient voltage protection.
