Description and Introduction

Power Inductors The part **SSB44-220** is manufactured by **北光 (Beiguang)**. Below are the factual specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Model:** SSB44-220  
- **Manufacturer:** 北光 (Beiguang)  
- **Type:** Solid-state relay (SSR)  
- **Load Voltage:** 220V AC  
- **Load Current:** 44A  
- **Control Voltage:** 3-32V DC (typically 5V, 12V, or 24V)  
- **On-State Voltage Drop:** ≤ 1.6V  
- **Off-State Leakage Current:** ≤ 2mA  
- **Isolation Voltage:** ≥ 2500V AC  
- **Switching Time:** ≤ 10ms  
- **Ambient Temperature Range:** -30°C to +80°C  
- **Mounting Type:** Screw terminal  
- **Housing Material:** Flame-retardant plastic  

### **Descriptions:**  
- The **SSB44-220** is a single-phase AC solid-state relay designed for high-current switching applications.  
- It provides **zero-crossing switching**, reducing inrush currents and electrical noise.  
- Suitable for resistive or inductive loads in industrial automation, heating systems, and motor control.  

### **Features:**  
- **High Load Capacity:** Supports up to **44A at 220V AC**.  
- **Optical Isolation:** Ensures safe separation between control and load circuits.  
- **No Moving Parts:** Solid-state design ensures long lifespan and silent operation.  
- **Overvoltage Protection:** Includes built-in snubber circuit for transient suppression.  
- **Compact & Durable:** Flame-retardant housing for reliable performance in harsh environments.  

This information is strictly based on the available technical data for the **SSB44-220** relay from 北光 (Beiguang).

Application Scenarios & Design Considerations

Power Inductors

Alternative Part Number

  • MBR440 --: Same 4A 40V Schottky diode rating in a different series, widely available and pin-compatible for most SSB44-220 applications.
  • 1N5822 --: 3A 40V Schottky diode with similar forward voltage and switching characteristics; a common cross-reference when 4A margin is not critical.
  • SR440 --: 4A 40V Schottky rectifier with comparable electrical ratings and a different naming series, suitable as a functional replacement.
  • SK44 --: 4A 40V Schottky rectifier in SMB/DO-214AA, equivalent ratings and similar low forward voltage drop, suitable drop-in replacement.
  • B440 --: 4A 40V Schottky diode in SMC package, same electrical ratings with higher surge capability, usable as an alternative with minor footprint adjustment.
