Description and Introduction

500 mW LL-34 Hermetically Sealed Glass Zener Voltage Regulators The TCLLZ20V is a transient voltage suppressor (TVS) diode manufactured by ON Semiconductor.  

### **Specifications:**  
- **Voltage - Reverse Standoff (VRWM):** 20V  
- **Voltage - Breakdown (VBR):** 22.2V (Min)  
- **Voltage - Clamping (VC):** 32.4V at 10A  
- **Peak Pulse Current (IPP):** 10A (8/20μs)  
- **Power - Peak Pulse (PPP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SOD-123  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).  
- Low clamping voltage for effective protection.  
- RoHS compliant.  

### **Features:**  
- Fast response time.  
- High surge capability.  
- Low leakage current.  
- Bidirectional TVS diode for versatile protection.

Application Scenarios & Design Considerations

500 mW LL-34 Hermetically Sealed Glass Zener Voltage Regulators

Alternative Part Number

  • BZT52C20 --: 20V zener diode in SOD-123 package, same voltage and function as the original, widely available and pin-compatible.
  • MMSZ5250B --: 20V zener diode in SOD-123, same manufacturer and electrical characteristics, direct functional replacement.
  • 1N4747A --: 20V 1W zener diode in DO-41 axial package, suitable alternative when through-hole mounting is acceptable.
