The SMBJ12CA is a bidirectional TVS diode designed for transient voltage suppression.
- Pin Count: 2 (standard SMB package)
- Function: Protects circuits from voltage transients (e.g., ESD, surges) by clamping excessive voltage (12V breakdown). It operates bidirectionally, meaning it safeguards against both positive and negative voltage spikes.
Key Parameters:
- Standoff Voltage (V_RWM): 12V
- Breakdown Voltage (V_BR): 13.3V (min)
- Peak Pulse Current (I_PP): High (varies by standard, e.g., 24.2A per IEC 61000-4-5).
Commonly used in power lines, data interfaces, and automotive systems for surge protection.
