Pinout

The SMAJ24CA-TR is a bidirectional TVS diode designed for transient voltage suppression.
- Pin Count: 2 pins (standard DO-214AC/SMA package).
- Function: Protects circuits from voltage spikes by clamping transient voltages (e.g., ESD, surges) to a safe level.
- Key Parameters:
- Standoff Voltage (V₃₀): 24V
- Breakdown Voltage (VBR): 26.7V (min)
- Peak Pulse Power: 400W (8/20μs waveform)
- Bidirectional Operation: Clamps both positive and negative transients.
Commonly used in power lines, communication ports, and automotive systems for surge protection.
