S602ECS

Scrs Overview

The Littelfuse S602ECS is a silicon-controlled rectifier (SCR) from the Sx02xS series, designed for sensitive gate triggering in low-current switching applications. It features a rated repetitive off-state voltage of 600 V and an on-state RMS current of 1.5 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-92-3 through-hole package. Key electrical parameters include a maximum holding current of 3 mA, a forward voltage of 1.7 V, and a non-repetitive peak on-state current of 15 A.

Scrs Feature Summary

• Sensitive gate architecture enables direct interfacing with microprocessors using minimal trigger current.
• Glass passivated junction construction ensures durability against environmental stressors.
• Compatible with lead-free reflow soldering processes for modern manufacturing requirements.

Scrs Applications

• Capacitive-discharge ignition systems
• Fluid level sensors
• Strobe light control circuits

Scrs Procurement Notes

Verify the specific suffix 'ECS' against official Littelfuse documentation to confirm exact packaging or tape-and-reel specifications, as standard listings often default to bulk or reel formats. Confirm RoHS compliance status directly with the manufacturer datasheet before finalizing procurement orders.

Scrs Selection Notes

Select this component when a 600 V blocking voltage and 1.5 A continuous current rating are required in a compact through-hole form factor. Ensure the application circuit can provide at least 800 mV gate voltage and 100 uA gate current for reliable turn-on. Verify thermal management capabilities for operation up to 125°C ambient conditions.

Scrs Part Context

This SCR belongs to the Sx02xS family, which offers various package options including surface mount and axial configurations. The S602ECS specifically provides a through-hole solution suitable for general-purpose power control where space constraints allow for larger packages compared to SMD alternatives.

Scrs Replacement Considerations

Direct pin-compatible replacements may include other 600 V, 1.5 A SCRs in TO-92 packages from manufacturers like Vishay or Microsemi. Verify gate sensitivity and holding current specifications match the original design requirements before substitution.
