X0402NF 1AA2

Scrs Overview

The X0402NF 1AA2 is a 4.0 Amp, 800 Volt Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics. It belongs to the Z04/X04 series and utilizes a TO-202 package for through-hole mounting. Key electrical parameters include a rated repetitive off-state voltage of 800 V, an on-state voltage of 1.8 V, and a gate trigger current of 0.2 mA. The device supports a non-repetitive peak on-state current of 33 A and operates within a temperature range of -40°C to +125°C.

Scrs Feature Summary

High sensitivity gate design requiring minimal trigger current for reliable activation in control circuits.
Robust thermal and electrical performance suitable for industrial systems and power tools.
Halogen-free molding and lead-free plating compliant with environmental standards.

Scrs Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm package type and pinout compatibility with existing PCB layouts. Check for end-of-life status or discontinuation notices from the manufacturer. Ensure storage conditions meet semiconductor handling requirements to prevent degradation prior to assembly.

Scrs Selection Notes

Select this SCR for applications requiring high current handling up to 4A RMS with sensitive gate drive capabilities. Consider the 800V blocking voltage for mains-connected loads. Evaluate thermal management needs given the TO-202 package constraints. Compare against similar series members like X0402MF if lower voltage ratings are sufficient for the specific circuit design.

Scrs Part Context

This component is part of STMicroelectronics' general-purpose SCR lineup designed for AC switching applications. It shares architectural similarities with other devices in the Z04/X04 family, offering standardized performance metrics for industrial and consumer electronics. The TO-202 package provides mechanical stability and efficient heat dissipation for through-hole implementations.
