The BTA26-700B is a high-performance 25 Ampere Triac designed for AC switching and phase control applications. Manufactured by Kersemi Electronic Co., Ltd., it offers robust performance and reliability for controlling various AC loads. The suffix 'B' likely indicates specific characteristics or a particular grade/version. It is commonly packaged in a TO-220 or similar through-hole package.

Applications:

• Heavy-duty light dimmers
• Industrial motor speed controllers
• Solid-state relays for high current applications
• Heater control systems
• AC power switching in industrial equipment

Features:

• High blocking voltage (700V)
• High surge current capability (250A)
• Triggering in all four quadrants
• Isolated mounting base (depending on package type)
• RoHS compliant

Benefits:

• Reliable and robust AC power control for high current loads
• Reduced component count simplifies designs
• Improved energy efficiency compared to electromechanical relays
• Long lifespan and minimal maintenance
• Enhanced safety due to high blocking voltage

Additional Details:

The BTA26-700B Triac has a repetitive peak off-state voltage of 700V, suitable for 230V AC line applications. It typically has a gate trigger current (Igt) less than 50mA in quadrants I and III, and less than 100mA in quadrants II and IV. The device's high surge current capability ensures reliable performance under transient load conditions, with a typical surge current rating of 250A for a single cycle. The holding current (Ih) is typically around 50mA. It operates over a temperature range of -40°C to +125°C. The TO-220 package (or similar) allows for efficient heat dissipation, and heatsinking may be required for high current applications. It provides a robust solution for AC power control in demanding industrial and commercial applications.
