Additional Details

The STF203-15.TC has a standoff voltage of 15V, a clamping voltage of approximately 20V (depending on test conditions), and a peak pulse power dissipation of 200W for an 8/20µs pulse. It is available in a small SOT-23 package, which is ideal for space-constrained applications. The device's bidirectional protection capability ensures that it can protect against both positive and negative voltage transients.

The low leakage current of the STF203-15.TC minimizes power consumption and prevents interference with sensitive signals. Its fast response time enables it to effectively suppress fast-rising transients, providing robust protection for downstream components. The device is also compliant with RoHS standards, ensuring that it does not contain any hazardous substances.
