Description and Introduction

8A SCRS The TYN608 is a thyristor (SCR - Silicon Controlled Rectifier) manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Voltage Rating (VDRM/VRRM):** 600V (repetitive peak off-state voltage)  
- **Current Rating (IT(RMS)):** 8A (RMS on-state current)  
- **Non-Repetitive Peak On-State Current (ITSM):** 80A (for 10ms half-sine wave)  
- **Gate Trigger Current (IGT):** 5mA (typical)  
- **Gate Trigger Voltage (VGT):** 1.5V (typical)  
- **Holding Current (IH):** 5mA (typical)  
- **On-State Voltage Drop (VTM):** 1.7V (typical at IT = 8A)  
- **Critical Rate of Rise of Off-State Voltage (dv/dt):** 50V/µs (minimum)  
- **Operating Junction Temperature (Tj):** -40°C to +125°C  

### **Descriptions:**
- The TYN608 is a standard planar passivated thyristor designed for general-purpose switching applications.  
- It is suitable for AC power control, motor control, and industrial automation.  
- The device is housed in a TO-220AB package, providing good thermal performance.  

### **Features:**
- **High Surge Current Capability:** Supports high non-repetitive peak currents.  
- **Planar Passivated Construction:** Ensures reliability and stability.  
- **Low Trigger Current:** Allows easy interfacing with control circuits.  
- **Isolated Tab (TO-220AB Insulated Package):** Provides electrical isolation for mounting on heatsinks.  

This information is based solely on the manufacturer's datasheet. For detailed application notes, refer to STMicroelectronics' official documentation.

Application Scenarios & Design Considerations

8A SCRS

Alternative Part Number

  • BT151-600R --: 600V 12A SCR in TO-220, widely available and a common substitute for TYN608-class thyristors with similar gate sensitivity.
  • 2N6507 --: 600V 16A SCR in TO-220 with comparable gate trigger current, a classic industry-standard alternative for TYN608 applications.
  • C106M --: 600V 4A sensitive-gate SCR in TO-202/TO-220, suitable for lower-current replacements where TYN608 is used in light-load switching.
  • BTB08-600B --: 8 A 600 V logic-level triac in TO-220, same package and current/voltage class as the TYN608, suitable drop-in for most switching loads.
  • BTA08-600B --: Snubberless 8 A 600 V triac from ST's BTA series, electrically comparable to the TYN608 with improved commutation performance.
  • MAC08BT1G --: 8 A 600 V triac from a different manufacturer and series, offering a second-source option with similar ratings and TO-220 package.
