Description and Introduction

PRECISION 4.0 VOLT MICROPOWER The part **ZRA400A03** is manufactured by **ZETEX**. Below are the factual specifications, descriptions, and features from the available knowledge base:  

### **Specifications:**  
- **Type:** Zener Diode  
- **Voltage (Vz):** 40V  
- **Power Dissipation (Ptot):** 400mW  
- **Tolerance:** ±5%  
- **Package:** SOD-323 (Small Outline Diode)  
- **Operating Temperature Range:** -65°C to +150°C  

### **Descriptions:**  
- The **ZRA400A03** is a surface-mount Zener diode designed for voltage regulation and protection in electronic circuits.  
- It provides a stable reference voltage of **40V** with a tight tolerance of **±5%**.  
- Suitable for low-power applications due to its **400mW** power dissipation capability.  

### **Features:**  
- **High reliability** for voltage stabilization.  
- **Compact SOD-323 package**, ideal for space-constrained PCB designs.  
- **Low leakage current** for improved efficiency.  
- **RoHS compliant**, meeting environmental standards.

Alternative Part Number

  • LM4040A30 --: Precision 3.0V shunt voltage reference with tight tolerance, functionally equivalent to the ZRA400A03 reference.
  • TL431A --: Adjustable shunt reference that can be set to 3.0V, widely available and commonly used as a substitute for Zetex shunt references.
  • KA431 --: Adjustable precision shunt regulator suitable for 3.0V reference applications, low cost and broadly stocked alternative.
  • LM4040A30IDBZR --: Precision 3.0V shunt voltage reference in SOT-23, a common functional replacement for a 3V reference with tight tolerance.
  • TL431AIDBZR --: Adjustable shunt reference that can be set to 3.0V, widely available and cost-effective for general reference applications.
  • ADR4530ARZ --: High-precision 3.0V series voltage reference offering low drift and low noise for demanding designs.
