SMBJ58CA

The SMBJ58CA is a bidirectional TVS (Transient Voltage Suppressor) diode designed to protect sensitive electronics from voltage transients, such as ESD (electrostatic discharge) and lightning-induced surges.
### Key Features:
- Voltage Rating: 58V (standoff)
- Peak Pulse Power: 600W (8/20µs waveform)
- Bidirectional Operation: Clamps both positive and negative transients
- Low Clamping Voltage: Limits overvoltage effectively
- Fast Response Time: Reacts in nanoseconds
### Applications:
- Power supply protection
- Communication lines (RS-485, Ethernet)
- Automotive and industrial systems
### Package:
- SMB (DO-214AA) surface-mount package
The SMBJ58CA is robust, reliable, and compliant with industry standards like IEC 61000-4-5 for surge protection. It’s ideal for safeguarding circuits against transient events in harsh environments.

The SMBJ58CA is a bidirectional TVS diode designed for transient voltage suppression.
- Pin Count: 2 (anode and cathode).
- Function: Protects circuits from voltage spikes by clamping transient voltages to a safe level (58V breakdown voltage). It operates bidirectionally, meaning it safeguards against both positive and negative voltage transients.
Commonly used in power lines, communication ports, and other sensitive electronics to prevent damage from ESD, lightning, or other surges.
Key Specs:
- Breakdown Voltage (V_BR): 64.4V (min) to 71.2V (max).
- Peak Pulse Power: 600W (8/20μs waveform).
- Package: SMB (DO-214AA).
Concise and effective for surge protection.
