Overview
The S2SRP is a Silicon-Controlled Rectifier (SCR) manufactured by Littelfuse Inc., designed for low-current switching applications. It features a peak off-state voltage of 200V and an on-state current rating of 800mA. The device utilizes a surface-mount DO-214 package, facilitating automated assembly on printed circuit boards. Key electrical parameters include a maximum gate trigger voltage of 800mV and a maximum gate trigger current of 200µA, indicating sensitive gate operation suitable for direct microprocessor interfacing. The component is classified as obsolete in current distribution channels.
Feature Summary
- Sensitive gate architecture enabling direct interface with low-power control logic
- Surface-mount DO-214 packaging for compact PCB integration
- High-reliability construction utilizing glass passivated junctions
Applications
- Strobe light triggering circuits
- Fluid level sensor interfaces
- Capacitive-discharge ignition systems
Procurement Notes
Verify the obsolete status of the S2SRP before initiating procurement processes. As the component is no longer actively produced or stocked by primary distributors, sourcing may require inventory from third-party suppliers or alternative authorized channels. Confirm availability and authenticity through verified distributors to ensure component integrity and compliance with quality standards prior to purchase.
Selection Notes
Select the S2SRP for applications requiring low-voltage, low-current SCR switching with minimal gate drive requirements. The 200V blocking capability and 800mA on-state current define its operational limits. Consider the surface-mount form factor for space-constrained designs. Evaluate compatibility with existing gate control circuitry due to the specific 800mV trigger voltage threshold and sensitive gate characteristics.
Part Context
The S2SRP belongs to the discrete Silicon-Controlled Rectifier category within Littelfuse's power semiconductor portfolio. These devices are engineered for precise, efficient switching in low-current electronic controls. The product line emphasizes durability through glass passivation and compatibility with lead-free reflow soldering processes, aligning with modern manufacturing standards for consumer and industrial electronics protection.
Replacement Considerations
Publicly confirmed substitute part numbers for the S2SRP are not available in the provided documentation. Due to the obsolete status of this specific model, engineers should consult Littelfuse technical support or authorized distributors for qualified alternatives that match the 200V/800mA specifications and DO-214 package constraints.
