- **Peak Pulse Current (IPP):** 23.1A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**
- The SMDJ43A is designed to protect sensitive electronics from high-voltage transients, such as ESD, lightning, and inductive load switching.  
- It is a bidirectional TVS diode, meaning it can suppress both positive and negative voltage transients.  
- The device is RoHS compliant and halogen-free.  

### **Features:**
- **High Power Handling:** Capable of absorbing large transient energy.  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **Surface Mount Package:** Suitable for automated PCB assembly.  
- **Bidirectional Operation:** Protects against both positive and negative voltage spikes.
