SA9.0CA 500 W Bidirectional TVS Diode – 9 V Standoff

SA9.0CA is a bidirectional tvs diode for transient-voltage suppression, with a 9 V reverse standoff voltage and 500 W peak pulse capability on a 10/1000 µs waveform. Its axial through-hole package suits compatible PCB assemblies and repair work.Key specifications Parameter Specification Part number SA9.0CA Device type Bidirectional TVS Diode Reverse standoff voltage (VRWM) 9 V Breakdown voltage range (VBR) 10.0–11.1 V Maximum clamping voltage (VC) 15.4 V at the reference datasheet's specified peak pulse current Peak pulse power 500 W (10/1000 µs waveform) Package DO-15 / DO-204AC Mounting / terminals Through hole / 2 axial leads Polarity Bidirectional Typical applications Transient protection on compatible low-voltage circuits Input and interface protection with verified capacitance and clamp requirements Repair of boards originally designed for SA9.0CA Selection notesChoose the standoff voltage above the circuit's highest normal operating voltage and verify the clamping voltage, pulse energy and thermal derating against the protected circuit. A TVS suppresses short transients; it does not regulate a continuous overvoltage.Frequently asked questionsWhat is SA9.0CA used for?SA9.0CA limits short voltage transients in circuits whose normal voltage, clamping limit and pulse requirements match its datasheet.Does SA9.0CA clamp at exactly 9 V?No. 9 V is its reverse standoff voltage. Breakdown starts within the specified 10.0–11.1 V range, and the reference maximum clamping voltage is 15.4 V at the specified pulse current.Is 500 W a continuous power rating?No. It is a peak pulse rating for the specified transient waveform. Continuous dissipation is much lower and depends on mounting and thermal conditions.Does SA9.0CA have polarity?It is a bidirectional TVS and can suppress transients in either direction.
