Description and Introduction

Zeners The IN4745A is a Zener diode manufactured by ONTC. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Zener Voltage (Vz):** 16V  
- **Power Dissipation (Pz):** 1W  
- **Tolerance:** ±5%  
- **Maximum Zener Impedance (Zzt):** 20Ω  
- **Test Current (Izt):** 17mA  
- **Reverse Leakage Current (Ir):** 5μA (at 12.2V)  
- **Operating Temperature Range:** -65°C to +200°C  

### **Descriptions:**  
- The IN4745A is a 1W Zener diode designed for voltage regulation applications.  
- It operates in the reverse breakdown region to maintain a stable voltage across its terminals.  
- The device is housed in a DO-41 axial-lead package for easy mounting.  

### **Features:**  
- **High Reliability:** Suitable for voltage stabilization in various circuits.  
- **Low Impedance:** Ensures stable voltage regulation under varying load conditions.  
- **Wide Operating Temperature Range:** Can function in extreme environments.  
- **Standard DO-41 Package:** Compatible with through-hole PCB assembly.  

This information is strictly based on the available knowledge base for the IN4745A Zener diode from ONTC.
