The BT1306-400D is a logic level sensitive gate triac designed for direct interfacing with microcontrollers, logic integrated circuits, and other low power gate trigger circuits. It operates as a general purpose bidirectional switch suitable for phase control applications. The device features a repetitive peak off-state voltage (VDRM) of up to 400 V and an on-state RMS current (IT(RMS)) rating of 0.6 A. Non-repetitive peak on-state current (ITSM) reaches 8 A for 20 ms pulses. The component utilizes a TO-92 plastic single-ended leaded package.
Verify the specific part number suffix against the manufacturer's official documentation to confirm exact electrical ratings and package variations. Ensure compatibility with existing circuit designs regarding thermal management and gate drive requirements before finalizing procurement decisions.
Select this component when interfacing directly with low power logic or microcontrollers requiring a sensitive gate trigger. Consider the 400 V off-state voltage limit and 0.6 A RMS current capacity relative to the load requirements. Evaluate thermal resistance characteristics for appropriate heat dissipation in the target application environment.
This component belongs to the BT1306 series of logic level triacs manufactured by NXP Semiconductors. The series includes variants with different voltage ratings, such as the BT1306-600D which supports up to 600 V. These devices are standardized within the SOT54 (TO-92) package family for general purpose switching tasks.
The BT1306-600D serves as a higher voltage variant within the same series. Verify functional equivalence and package compatibility when considering substitutes from other manufacturers.
