The BT136X-800 is a triac from Teccor Electronics (now Littelfuse). Triacs are bidirectional thyristors, making them suitable for AC switching and phase control applications.

Applications:

• AC Motor Control: Used in controlling the speed of small AC motors in appliances and industrial equipment.
• Lighting Control: Enables dimming and switching of incandescent, halogen, and some LED lighting systems.
• Heater Control: Used to regulate the temperature of electric heaters, ovens, and other heating elements.
• Solid State Relays (SSRs): Functions as the switching element in SSRs for controlling AC loads.

Features:

• Bidirectional Switching: Can switch AC current in both directions, simplifying circuit design.
• High Blocking Voltage: Withstands high voltage levels in the off-state, preventing unwanted triggering. The '-800' designation indicates a voltage rating of 800V.
• Low On-State Voltage: Minimizes power dissipation during conduction, improving efficiency.
• High Surge Current Capability: Can handle brief, high-current surges without damage, enhancing reliability.
• Sensitive Gate Triggering: Requires a relatively small gate current to trigger the device, simplifying interface with control circuits.

Benefits:

• Efficient AC Switching: Provides a reliable and efficient means of switching AC loads.
• Precise Phase Control: Enables precise control of AC power, useful for dimming lights and controlling motor speed.
• Reduced Circuit Complexity: Bidirectional switching simplifies circuit design compared to using individual SCRs.
• Improved Reliability: High surge current capability and robust construction enhance reliability in demanding applications.

Additional Details:

The BT136X-800 is typically available in a through-hole package, such as a TO-220. The specific dimensions and pinout are standard for this package type. It is crucial to consult the product datasheet from Littelfuse for detailed specifications, including voltage and current ratings, gate trigger characteristics, thermal resistance, and package dimensions. The datasheet also provides guidance on proper mounting, heat sinking, and protection circuitry. Ensure proper heat sinking to prevent overheating, especially in high-power applications. Snubber circuits may be required to suppress voltage transients and prevent false triggering. Always adhere to the manufacturer's recommended operating conditions and safety guidelines.
