BTA40-600B TRIAC 600V 40A RD91 Insulated
The BTA40-600B TRIAC 600V 40A RD91 Insulated is a rugged, high-current silicon TRIAC supplied in an insulated RD91 package and designed for mains AC switching and phase-control applications, offering 600V repetitive peak off-state voltage, 40A RMS continuous on-state capability, high non-repetitive surge rating, robust dv/dt immunity and low junction-to-case thermal resistance for reliable heatsink mounting and industrial operation.
Features
- 600V repetitive peak off-state voltage for mains-rated applications.
- 40A RMS on-state current capability for continuous AC conduction.
- High non-repetitive surge on-state current for inrush and transient tolerance.
- Low on-state voltage (VTM) for efficient conduction and reduced power dissipation.
- High commutation capability and low dynamic resistance for robust switching.
- High dv/dt immunity to minimise false triggering on inductive loads.
- Insulated RD91 package with low junction-to-case thermal resistance for predictable thermal design.
- RoHS-compliant epoxy package with UL94 V-0 flammability rating for safe handling and PCB mounting.
