Overview
The TIC201D-S is a silicon triac from the TIC201 series, featuring a glass-passivated wafer and sensitive gate design. It offers a repetitive peak off-state voltage (VDRM) of 400 V and supports a full-cycle RMS on-state current (IT(RMS)) of 2.5 A at case temperatures up to 85°C. The device handles a peak on-state surge current (ITSM) of 12 A. Electrical characteristics include a maximum gate trigger current (IGT) of 5 mA in Quadrant 1 operation. Thermal management specifies a junction-to-case thermal resistance (RθJC) of 10 °C/W. The component operates within an operating case temperature range of -40°C to +110°C and utilizes a TO-220 package.
Feature Summary
- Sensitive gate triac architecture for reliable triggering with low gate current requirements.
- Glass passivation provides enhanced protection against environmental stressors.
- Robust surge handling capability suitable for inductive load switching applications.
Applications
- Solid-state relays
- Motor speed control circuits
- Lighting dimmer controls
Procurement Notes
Verify the obsolete status of this specific part number before initiating any procurement activities. Confirm that the 400 V rating aligns with system voltage requirements. Ensure the TO-220 package dimensions fit the designated PCB layout. Validate thermal dissipation calculations against the specified RθJC values for the intended operating environment.
Selection Notes
Select the TIC201D-S when a 400 V blocking voltage is required alongside a 2.5 A continuous current capacity. Consider the sensitive gate characteristic for compatibility with low-power control logic. Evaluate the TO-220 package for adequate heat sinking solutions given the thermal resistance specifications. Compare against higher voltage variants if system transients exceed 400 V.
Part Context
The TIC201D-S belongs to the broader TIC201 series of silicon triacs manufactured by Bourns Inc. This series includes variants with different off-state voltage ratings, specifically the TIC201M (600 V) and TIC201S (700 V). All members share common physical packaging and general electrical performance traits, differing primarily in their voltage blocking capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic TO-220 triac replacements by matching the 400 V VDRM, 2.5 A IT(RMS), and sensitive gate trigger specifications.
