Description and Introduction

500 WATT PEAK POWER TRANSIENT VOLTAGE SUPPRESSORS The part SA70A is manufactured by ON Semiconductor. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** ON Semiconductor  
- **Part Number:** SA70A  
- **Type:** Schottky Barrier Diode  
- **Package:** SOD-123  
- **Maximum Reverse Voltage (VR):** 70 V  
- **Average Rectified Forward Current (IO):** 1 A  
- **Peak Forward Surge Current (IFSM):** 30 A  
- **Forward Voltage Drop (VF):** 0.55 V (at 1 A)  
- **Reverse Leakage Current (IR):** 100 µA (at 70 V)  
- **Operating Temperature Range:** -65°C to +125°C  

### **Descriptions:**  
The SA70A is a high-performance Schottky barrier diode designed for applications requiring low forward voltage drop and fast switching. It is housed in a compact SOD-123 package, making it suitable for space-constrained designs.  

### **Features:**  
- **Low Forward Voltage Drop:** Enhances efficiency in power applications.  
- **Fast Switching Speed:** Ideal for high-frequency circuits.  
- **High Surge Current Capability:** Ensures reliability under transient conditions.  
- **Compact Package (SOD-123):** Suitable for surface-mount applications.  
- **High Reverse Voltage (70 V):** Provides robust protection in circuits.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

500 WATT PEAK POWER TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • P6KE75A --: Unidirectional 600W TVS diode with similar standoff voltage and clamping characteristics, widely available and commonly used as a drop-in replacement for SA-series 500W parts in many designs.
  • 1.5KE75A --: Unidirectional 1500W TVS diode offering higher surge capability than the SA70A; suitable when extra transient protection margin is acceptable and package size allows.
  • SMAJ70A --: Surface-mount 400W unidirectional TVS diode with 70V standoff, a good fit for space-constrained boards needing similar clamping performance to the SA70A.
  • BZW06-70 --: 600W unidirectional transient voltage suppressor with 70V standoff, functionally equivalent to the SA70A and readily sourced.
