Overview
The S602TSRP is a Silicon Controlled Rectifier (SCR) from the Littelfuse EV Series, designed for surface mount applications in the SOT-223 package. It features a sensitive gate architecture with a rated repetitive off-state voltage of 600 V and an RMS on-state current capability of 1.5 A. The device exhibits a maximum gate trigger voltage of 0.8 V and a maximum gate trigger current of 200 µA, facilitating direct microprocessor interfacing. Key electrical parameters include a maximum on-state voltage of 1.5 V, a holding current of 5 mA, and a non-repetitive surge current rating of 25 A at 60 Hz. The component operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- Sensitive gate design enables direct interface with low-power logic circuits and microprocessors.
- High static dv/dt noise immunity provided by planar construction design.
- Improved turn-off time (tq) less than 35 microseconds for enhanced switching performance.
- Glass-passivated junctions ensure long-term reliability and parametric stability.
Applications
- General purpose AC power control circuits
- Lighting dimmer applications
- Motor speed control systems
Procurement Notes
Verify the specific suffix 'RP' against the manufacturer's official datasheet to confirm packaging configuration, as ordering suffixes may indicate variations in reel or cut tape specifications. Ensure the requested part matches the exact voltage and current ratings required for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a surface mount SCR with 600 V blocking capability and 1.5 A RMS current handling is required. The sensitive gate characteristic makes it suitable for low-power drive applications. Verify that the SOT-223 thermal dissipation characteristics meet the system's heat management requirements under continuous load conditions.
Part Context
The S602TSRP belongs to the Sx02xS series of 1.5 Amp sensitive gate SCRs manufactured by Littelfuse. This series utilizes small die planar construction to achieve high dv/dt immunity and fast turn-off times. The product line includes both through-hole and surface mount variants to accommodate different PCB layout constraints.
Replacement Considerations
Direct replacements within the same series include S602TS1RP and S602CSRP. Verify pinout compatibility and thermal resistance differences between SOT-223 and alternative packages like TO-92 or SOT-89 before substituting.
