What are the key features of BTA26-600BW?
- 25 A RMS on-state current and 600 V repetitive peak voltage rating handles demanding AC line switching in industrial heaters and motor controls
- 500 V/µs minimum critical rate of rise of off-state voltage (dV/dt) ensures robust noise immunity in high-di/dt switching environments
- Isolated TO-3P (TOP3) package decouples the heat-sink tab from line potential, simplifying thermal design without additional insulating hardware
What is BTA26-600BW used for?
BTA26-600BW is well suited for phase-angle control of resistive and inductive AC loads such as electric heaters, lighting dimmers, and single-phase motor speed controllers. Its 600 V blocking voltage and 25 A current rating cover the full range of 115 V and 230 V mains applications. The isolated package makes it easy to mount on a grounded heat sink in household appliances, HVAC systems, and industrial process-control panels.

Frequently Asked Questions
Can BTA26-600BW control a 2 kW resistive heater on a 230 V AC mains supply?
Yes. At 230 V RMS, a 2 kW heater draws approximately 8.7 A RMS, well within BTA26-600BW's 25 A RMS continuous rating. The device's 600 V repetitive peak voltage provides a margin of more than 2× over the 325 V peak of a 230 V supply, ensuring reliable long-term operation.
What gate drive current is required to trigger BTA26-600BW reliably in all four quadrants?
BTA26-600BW requires a maximum DC gate trigger current of 50 mA and a gate trigger voltage not exceeding 1.5 V. In practice a gate pulse of 20–50 mA for at least 10 µs, sourced from a simple opto-triac driver, ensures consistent firing in quadrants I, II, and III across the full –40 °C to 125 °C temperature range.
How does the isolated TOP3 package of BTA26-600BW reduce insulation requirements compared to non-isolated TRIACs?
In non-isolated packages the metal tab is electrically connected to the main terminal, requiring an insulating pad and bushing on the heat sink. BTA26-600BW's isolated TOP3 case separates the tab from live terminals up to 600 V, eliminating the insulating pad and allowing direct mounting on a grounded chassis—saving assembly time and 2–5 °C/W of additional thermal resistance introduced by mica or silicone insulators.
