Description and Introduction

1A TRIACS **Part Number:** Z0109NA 2AL2  
**Manufacturer:** STMicroelectronics (ST)  

### **Specifications:**  
- **Type:** TRIAC (bidirectional thyristor)  
- **Voltage Rating (VDRM/VRRM):** 600V  
- **Current Rating (IT(RMS)):** 1A  
- **Gate Trigger Current (IGT):** 5mA (typical)  
- **On-State Voltage (VTM):** 1.7V (typical at IT = 1A)  
- **Holding Current (IH):** 5mA (typical)  
- **Critical Rate of Rise of Off-State Voltage (dv/dt):** 50V/µs (minimum)  
- **Isolation Voltage (Visol):** 2500V RMS  
- **Package:** TO-92 (through-hole)  

### **Descriptions and Features:**  
- Designed for general-purpose AC switching applications.  
- Suitable for resistive or inductive loads.  
- Snubberless operation (high commutation capability).  
- Sensitive gate triggering for low-power control.  
- High noise immunity.  
- Compliant with RoHS standards.  

This TRIAC is commonly used in light dimmers, motor controls, and heating regulation circuits.

Application Scenarios & Design Considerations

1A TRIACS

Alternative Part Number

  • MAC97A8 --: Sensitive-gate triac in TO-92 with similar 0.8A/600V ratings and low gate trigger current, a common drop-in replacement for Z0109 series.
  • BT136-600E --: Widely available 4A/600V triac with sensitive gate, higher current margin than the original and suitable for most Z0109NA applications.
  • L0109NE --: 1A/800V sensitive-gate triac in TO-92 package, offers higher voltage margin and similar gate sensitivity for direct substitution.
  • MAC97A6 --: Sensitive-gate triac in TO-92 with similar 400V/0.8A ratings, widely available and a common drop-in for small AC switching applications.
