Overview
The Littelfuse S602ECSAP is a Silicon Controlled Rectifier (SCR) belonging to the Teccor HF Sx02xS series. It features a sensitive gate design suitable for direct microprocessor interface and offers high static dv/dt noise immunity. The device utilizes small die planar construction with glass-passivated junctions for reliability. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 600 V, an on-state RMS current (It RMS) of 1.5 A, and a maximum gate trigger current (IGT) of 200 uA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Sensitive gate architecture enabling direct interfacing with low-power logic circuits
- High static dv/dt noise immunity for stable operation in electrically noisy environments
- Glass-passivated junctions ensuring long-term parametric stability and reliability
Applications
- Motor speed control circuits
- Lighting dimmer applications
- Solid-state relay inputs
- General purpose switching
Procurement Notes
Verify the specific suffix 'ECSAP' against official Littelfuse documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required mounting style and packaging format for your assembly process. Cross-reference datasheets for exact mechanical dimensions and handling instructions.
Selection Notes
Select this component when a 1.5 A SCR with 600 V blocking capability is required. The sensitive gate characteristic makes it ideal for designs driven by microcontrollers or low-current logic outputs. Consider thermal management requirements for the TO-92 or surface mount package depending on the specific suffix configuration.
Part Context
This part belongs to the Sx02xS family of 1.5 Amp sensitive SCRs from Littelfuse. The series is characterized by improved turn-off times and robust construction. Variants within this family differ primarily in package style (through-hole vs. surface mount) and voltage ratings, sharing common gate sensitivity and noise immunity features.
Replacement Considerations
Direct substitutes may include other 1.5 A, 600 V sensitive gate SCRs in compatible packages. Verify pinout compatibility and gate trigger characteristics before substitution. Consult manufacturer cross-reference guides for equivalent parts from other thyristor suppliers.
