BTA40-600B TRIAC 600V 40A RD91 Insulated

Description

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.
