Overview
The S602CSRP is a silicon-controlled rectifier (SCR) from the Littelfuse Sx02xS series, rated for 1.5 A RMS on-state current and 600 V repetitive peak off-state voltage. It utilizes a sensitive gate design requiring low trigger current for direct microprocessor interfacing. The device features glass-passivated junctions for reliability and offers high static dv/dt noise immunity with an improved turn-off time of less than 35 microseconds. It is housed in a compact package suitable for surface mount applications.
Feature Summary
- Sensitive gate architecture enabling direct interface with microprocessors
- High static dv/dt noise immunity for stable operation
- Improved turn-off time (tq) under 35 microseconds
- Glass-passivated junctions ensuring long-term parametric stability
Applications
- Strobe light control circuits
- Fluid level sensing systems
- Capacitive-discharge ignition systems
Procurement Notes
Verify the specific package type and pinout configuration against the official datasheet before integration, as surface mount variants may differ from through-hole equivalents within the same series. Confirm RoHS compliance status and halogen-free certification requirements for your manufacturing process. Ensure the selected component matches the required voltage and current ratings for the target application circuit to prevent failure.
Selection Notes
Select this component when a sensitive gate SCR is required for low-power switching applications involving microprocessor control. The 600 V rating suits general-purpose AC/DC switching tasks. Consider the surface mount form factor for automated assembly processes where space constraints exist. Evaluate the turn-off time specifications against the frequency requirements of the load being controlled to ensure reliable commutation.
Part Context
This part belongs to the Teccor brand Sx02xS series of 1.5 Amp sensitive SCRs. The series is characterized by planar construction designs that provide robust performance in low-current circuits. These devices are engineered for efficiency and precise switching, offering a range of packages including surface mount options to accommodate diverse PCB layout needs.
Replacement Considerations
Cross-reference with other Sx02xS series parts such as S602TS1RP or S602ES if package compatibility differs. Verify that substitute components maintain the 600 V blocking voltage and 1.5 A current ratings. Ensure the replacement also features sensitive gate characteristics to preserve microprocessor interface functionality without additional driver circuitry.
