The Q0170RA is a logic-level gate Triac manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It is designed for switching AC loads and is particularly suited for applications where the gate drive current is limited, such as microcontroller-based control systems. This Triac offers reliable performance and is a good choice for controlling inductive and resistive loads in AC circuits.

Applications:

• Solid-state relays
• Light dimmers
• Motor speed controls
• Solenoid controls
• Heater controls

Features:

• Logic-level gate triggering
• High blocking voltage (VDRM = 600 V)
• Low on-state voltage
• High surge current capability
• Isolation voltage up to 2500 Vrms
• RoHS compliant

Benefits:

• Easy interface with microcontrollers and logic circuits
• Suitable for high-voltage AC applications
• Efficient switching performance due to low on-state voltage
• Robust performance under surge conditions
• Provides isolation between the control circuit and the AC load
• Environmentally friendly due to RoHS compliance

Additional Details:

The Q0170RA typically has a repetitive peak off-state voltage (VDRM) and VRRM of 600V, allowing it to safely switch AC voltages up to this level. The on-state RMS current (IT(RMS)) is typically around 1 Ampere. The gate trigger current (IGT) is typically low, making it compatible with logic-level outputs from microcontrollers. It often comes in a TO-92 or similar through-hole package. The operating junction temperature range is typically from -40°C to +125°C. It is widely used in appliances, industrial controls, and lighting systems where AC loads need to be switched efficiently and reliably.
