Description and Introduction

500 mW LL-34 Hermetically Sealed Glass Zener Voltage Regulators The TCLLZ7V5 is a transient voltage suppressor (TVS) diode manufactured by TC (Taiwan Semiconductor). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Part Number:** TCLLZ7V5  
- **Type:** Unidirectional TVS Diode  
- **Working Voltage (VWM):** 6.4V  
- **Breakdown Voltage (VBR):** 7.5V (Min) – 8.3V (Max)  
- **Clamping Voltage (VC):** 12.4V (Max) at 1A  
- **Peak Pulse Current (IPP):** 1A (8/20μs waveform)  
- **Maximum Reverse Leakage Current (IR):** 1μA (at VWM)  
- **Power Dissipation (PPK):** 400W (8/20μs pulse)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SOD-123  

### **Description:**
The TCLLZ7V5 is designed to protect sensitive electronics from voltage transients, such as electrostatic discharge (ESD), lightning surges, and inductive load switching. It provides fast response time and low clamping voltage for effective overvoltage protection.

### **Features:**
- **Unidirectional TVS Diode** (protects against positive transients)  
- **Low Clamping Voltage** for enhanced circuit protection  
- **High Surge Capability** (1A peak pulse current)  
- **Fast Response Time** (typically <1ns)  
- **Compact SOD-123 Package** for space-constrained applications  
- **RoHS Compliant** (lead-free and environmentally friendly)  

This information is based solely on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations
