Overview
The Littelfuse S4006L is a bidirectional triac belonging to the Qxx06xx series, designed for AC switching and phase control applications. It features a 400V repetitive peak off-state voltage (VDRM) and supports a continuous on-state current (IT(RMS)) of 6A. The device utilizes a TO-220-2 package with an electrically isolated tab, rated at 2500V rms isolation from leads to mounting surface. Key electrical parameters include a maximum gate trigger voltage (VGT) of 25mA equivalent drive capability, an on-state voltage drop (VTM) of 1.6V, and a holding current specification. The component incorporates glass-passivated junctions for parameter stability and reliability under thermal stress.
Feature Summary
- Integrated bidirectional AC switching capability for phase control circuits
- Electrically isolated TO-220-2 package eliminates need for external insulators
- Glass-passivated junctions ensure long-term parameter stability
Applications
- AC speed controls
- Temperature modulation controls
- Lighting controls requiring noise immunity
Procurement Notes
Verify the specific suffix against the official Littelfuse datasheet to confirm exact electrical tolerances and packaging options. Ensure the procurement channel provides authentic Littelfuse components with traceable documentation. Check for RoHS compliance status in the latest product change notification before finalizing orders.
Selection Notes
Select this component when a 400V rating and 6A continuous current are required for AC load switching. The TO-220-2 package facilitates heatsinking for higher power dissipation scenarios. Consider the 2500Vrms isolation feature if direct mounting to grounded chassis is necessary without additional insulation barriers.
Part Context
This part belongs to the Teccor brand Quadrac/triac family from Littelfuse, which specializes in thyristor solutions for power control. The Qxx06xx series denotes a standard triac line offering robust performance for industrial and consumer AC control applications, distinct from the integrated Quadrac variants that include internal diacs.
Replacement Considerations
Consult Littelfuse official substitution guides for compatible triacs within the same voltage and current ratings. Verify pinout compatibility and thermal resistance characteristics when replacing with devices from other manufacturers or different Littelfuse series.
