BTA26-600B TRIAC 600V 25A TOP-3 Insulated
The BTA26-600B TRIAC 600V 25A TOP-3 Insulated is a high-current silicon-controlled rectifier in an insulated TOP-3 package designed for mains AC switching and phase control applications, offering 600V repetitive peak off-state voltage, 25A RMS on-state current capability, strong non-repetitive surge performance, and well-defined thermal characteristics suitable for heatsink mounting and reliable industrial operation.
Features
- 600V repetitive peak off-state voltage rating for mains applications.
- 25A RMS on-state current capability for continuous AC conduction.
- High non-repetitive surge current tolerance for inrush and transient events.
- Low on-state voltage for efficient conduction and reduced power loss.
- Robust gate triggering performance with standard IGT for reliable turn-on.
- High dv/dt immunity to minimise false triggering on inductive loads.
- Insulated TOP-3 package with defined junction-to-case thermal resistance for predictable thermal design.
- Epoxy body meeting UL94 V-0 flammability for safe PCB mounting and handling.
