Specifications

The STF202-30.TCT typically features a reverse standoff voltage of 30V, a peak pulse power of several hundred watts (depending on the test waveform), and a low clamping voltage. Specific values can be found in the manufacturer's datasheet. Package type is typically a small outline transistor (SOT) package, such as SOT-23 or similar. It is designed to protect one I/O line or power line from transient overvoltages by clamping the overvoltage to a safe level. The device also offers low leakage current, which helps to minimize power consumption in the protected circuit.
