Additional Details

The SM5S24 features a standoff voltage of 24 V. At a peak pulse current of 34.7 A, it exhibits a typical clamping voltage around 38.9 V. It is housed in an SMC (DO-214AB) package for easy surface mounting. This device is designed to withstand high surge currents, making it suitable for applications where protection from transient voltage events is critical. Its operating temperature range typically spans from -55°C to +150°C.

The unidirectional version is commonly used in DC circuits, while the bidirectional version is suitable for AC circuits or DC circuits where reverse polarity protection is needed. Optimal board layout is crucial for achieving peak performance; it is recommended to minimize trace lengths to reduce parasitic inductance. The device is lead-free and compliant with RoHS standards, reflecting its environmentally friendly design.
