Description and Introduction

TRIACs 8 AMPERES RMS 200 thru 800 VOLTS The **MAC228A8** is a specific part manufactured by **ON Semiconductor**. Below are the factual details about its specifications, descriptions, and features based on available knowledge:  

### **Specifications:**  
- **Manufacturer:** ON Semiconductor  
- **Part Number:** MAC228A8  
- **Type:** Triac (Thyristor)  
- **Voltage Rating:** Typically 600V or 800V (exact value depends on datasheet)  
- **Current Rating:** Typically 8A (exact value depends on datasheet)  
- **Gate Trigger Current (I_GT):** Typically in the range of 5mA to 50mA  
- **On-State Voltage (V_T):** Low voltage drop in conducting state  
- **Package Type:** TO-220AB (common for Triacs)  

### **Descriptions:**  
- The **MAC228A8** is a high-performance **Triac** designed for AC power control applications.  
- It is commonly used in **lighting controls, motor drives, and heating regulation** circuits.  
- Suitable for **phase-angle and zero-crossing switching** applications.  

### **Features:**  
- **High Voltage Capability** – Designed for mains voltage applications (110V–240V AC).  
- **Sensitive Gate** – Low gate trigger current for improved control efficiency.  
- **High Noise Immunity** – Robust against electrical noise in switching environments.  
- **Isolated Tab** – Allows easier mounting on heat sinks without electrical isolation.  

For precise values, always refer to the official **ON Semiconductor datasheet** for the **MAC228A8**.

Alternative Part Number

  • Q6008L5 --: Triac rated 600V/8A in TO-220, functionally equivalent to the MAC228A8 with similar current and voltage ratings.
  • BT138-600E --: 8A 600V sensitive-gate triac in TO-220, a common drop-in replacement for MAC228 series triacs.
  • BTA08-600C --: 8A 600V snubberless triac in TO-220, widely available and suitable as an alternative to the MAC228A8.
  • Q4008L4 --: Triac in the same 8 A / 400 V class with similar gate sensitivity, suitable for AC switching applications.
  • BTA08-600B --: 8 A 600 V snubberless triac with higher voltage margin, a common replacement for 400 V class triacs.
  • BT136-600E --: 4 A 600 V triac with sensitive gate; usable in lower-current designs where the original 8 A rating is not fully utilized.
