Overview
The S2004DS1TP is a sensitive gate silicon controlled rectifier (SCR) manufactured by Littelfuse Inc. It features a 200V repetitive peak off-state voltage and a 4A average on-state current rating. The device is housed in a surface-mount TO-252 (DPAK) package, designed for automated assembly processes. This component serves as a switching element in low-power electronic circuits requiring reliable gate triggering characteristics.
Feature Summary
- Sensitive gate structure for efficient triggering
- Surface mount TO-252 package design
- High thermal stability capabilities
Applications
- Low power AC/DC switching circuits
- General purpose thyristor applications
- Consumer electronics protection
Procurement Notes
Verify the specific suffix 'TP' to confirm the tape and reel packaging configuration required for surface mount manufacturing lines. Ensure that the procurement source provides documentation confirming the component's compliance with relevant environmental standards, such as RoHS directives, if applicable to your project requirements. Cross-reference the manufacturer's part number directly to avoid substitutions with non-compatible variants.
Selection Notes
Select this component when a surface mount SCR with a 200V blocking capability and 4A current handling is required. The sensitive gate characteristic makes it suitable for applications where low gate drive current is necessary. Consider the thermal dissipation limits of the TO-252 package when designing the PCB layout to ensure reliable operation under continuous load conditions.
Part Context
This part belongs to the Littelfuse SCR family, specifically designed for surface mount technology integration. It complements other thyristors in the portfolio by offering a compact footprint suitable for modern printed circuit board designs. The series focuses on providing robust switching performance in space-constrained electronic assemblies.
Replacement Considerations
The S2004DS1RP is a listed equivalent variant from the same manufacturer. Verify pinout compatibility and electrical specifications before substitution. Ensure that any replacement maintains the sensitive gate requirement and surface mount package integrity.
