Description and Introduction

TECHNICAL SPECIFICATIONS OF SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMBJ11A is a surface mount transient voltage suppressor (TVS) diode manufactured by CR (likely referring to CR Microelectronics or another manufacturer with the "CR" designation). Below are the factual specifications, descriptions, and features based on available knowledge:

### **Specifications:**
- **Voltage Rating (Vₓ):** 11V  
- **Breakdown Voltage (VBR):** 12.2V (min) – 13.5V (max) at 1mA  
- **Peak Pulse Power Dissipation (Pppm):** 600W (10/1000μs waveform)  
- **Clamping Voltage (Vc):** 17.9V at 1A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Reverse Standoff Voltage (Vrwm):** 11V  
- **Leakage Current (Ir):** 1μA (max) at Vrwm  
- **Junction Capacitance (Cj):** Typically 300pF (at 0V, 1MHz)  

### **Description:**  
The SMBJ11A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients, electrostatic discharge (ESD), and electrical surges. It is housed in an SMB (DO-214AA) package, making it suitable for surface-mount applications.  

### **Features:**  
- **Fast Response Time:** Typically <1ns  
- **Low Clamping Voltage:** Provides effective protection for downstream components.  
- **High Surge Capability:** Handles high transient energy.  
- **Unidirectional Polarity:** Protects against positive voltage spikes.  
- **RoHS Compliant:** Meets environmental standards.  

For exact details, always refer to the manufacturer's datasheet.

Alternative Part Number

  • P6SMB11A --: Same 600W SMB unidirectional TVS with 11V standoff, drop-in form factor and equivalent clamping performance.
  • 1SMB11AT3G --: 600W SMB unidirectional TVS with matching 11V standoff voltage, widely available and electrically equivalent.
  • SMAJ11A --: 400W SMA unidirectional TVS with same 11V standoff; lower power rating but suitable for many clamping needs and a different series for easy distinction.
