Selection Notes
Exact comparison anchors for SMBJ30CA: Polarity: Bidirectional; Reverse Standoff Voltage (VRWM): 30V; Clamping Voltage: 48.4V; Peak Pulse Current (IPP): 12.4A.
Coordinate VRWM with the normal signal/rail voltage and verify clamping voltage plus pulse-current/power capability for the surge waveform.
Design Considerations
- Coordinate VRWM with the normal signal/rail voltage and verify clamping voltage plus pulse-current/power capability for the surge waveform.
