S602ESAP

Scrs Overview

The Littelfuse S602ESAP is a Silicon Controlled Rectifier (SCR) from the HF Sx02xS series, designed for sensitive gate applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 1.5 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-92 through-hole package. Key electrical parameters include a maximum holding current of 5 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 200 uA. It exhibits a forward voltage drop of 1.7 V and a non-repetitive peak on-state current of 15 A.

Scrs Feature Summary

• Sensitive gate architecture enabling direct interface with microprocessors
• High static dv/dt noise immunity for reliable operation in noisy environments
• Improved turn-off time (tq) less than 35 microseconds
• Glass-passivated junctions ensuring long-term reliability and parametric stability

Scrs Applications

• Microprocessor-controlled switching circuits
• AC power control systems requiring high noise immunity
• General purpose thyristor applications in consumer electronics

Scrs Procurement Notes

Verify the specific suffix 'AP' against official Littelfuse documentation to confirm it denotes the standard tape-and-reel or bulk packaging variant for the S602ES component. Ensure the ordering part number matches the required package style and compliance status, as suffixes may indicate specific manufacturing lot or environmental certifications distinct from the base model.

Scrs Selection Notes

Select this component when a 600 V, 1.5 A SCR with sensitive gate drive characteristics is required. The TO-92 through-hole package suits prototyping and low-volume assembly. Verify that the 200 uA gate trigger current aligns with the driving circuit's output capability, and ensure the 5 mA holding current is sufficient to maintain conduction in the target load application.

Scrs Part Context

The S602ESAP belongs to the Littelfuse Teccor brand HF Sx02xS series of 1.5 Amp sensitive SCRs. This family emphasizes small die planar construction for improved performance metrics like turn-off time and dv/dt immunity compared to older generations. The 'ES' designation typically indicates the 600 V rating and TO-92 package configuration within this product line.

Scrs Replacement Considerations

Direct replacements must match the 600 V VDRM, 1.5 A IT(RMS), and TO-92 package. Check datasheets for equivalent sensitive gate SCRs from other manufacturers, ensuring comparable IGT and IH values. Verify pinout compatibility and thermal characteristics before substituting.
