S6055NTP

Overview

The Littelfuse S6055NTP is a Silicon Controlled Rectifier (SCR) belonging to the Teccor Sxx55x series. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 55 A. The device has a maximum gate trigger current of 40 mA and a forward voltage of 1.8 V. It operates within a temperature range of -40°C to +125°C and utilizes an SMTO-218 through-hole package.

Feature Summary

• Sensitive gate design allows for direct interfacing with microprocessors using minimal gate current.
• Glass passivated junction structure ensures durability against environmental stress.
• Compatible with lead-free reflow soldering processes for modern manufacturing requirements.

Applications

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

Procurement Notes

Verify the specific suffix 'NTP' against official Littelfuse documentation, as standard listings often use 'RTP' or 'MTP'. Confirm RoHS compliance status and ensure the SMTO-218 package matches the target PCB footprint before ordering.

Selection Notes

Select this component for applications requiring 600V blocking capability and 55A continuous current handling in a through-hole configuration. Ensure the gate drive circuit can supply at least 40mA to guarantee reliable triggering under all operating conditions.

Part Context

This part belongs to the Littelfuse Teccor Sxx55x family of high-power SCRs. These devices are engineered for efficient switching in low-current control circuits and offer robust surge capabilities suitable for demanding electronic controls and industrial applications.

Replacement Considerations

S6055RTP and S6055MTP are confirmed substitutes within the same series offering identical electrical ratings. Verify that the alternative package type is compatible with the existing assembly process.
