X0202NA2BL2

Scrs Overview

The X0202NA2BL2 is a logic-level Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics in the X02 series. It features a TO-92 through-hole package with three pins. Key electrical parameters include an on-state RMS current of 1.25 A, repetitive peak off-state voltage ratings of 600 V or 800 V, and a gate triggering current range of 50 to 200 µA. The device supports a surge current rating of 25 A and operates within a temperature range of -40°C to 125°C.

Scrs Feature Summary

• Optimized for low forward voltage drop and high inrush current capabilities to reduce power losses.
• Logic-level gate sensitivity suitable for applications with limited gate drive current.
• Designed for high reliability in harsh environments.

Scrs Applications

• On/off switching functions where topology does not offer high current for gate triggering
• AC switch applications requiring reduced power losses
• Power switching circuits demanding high reliability

Scrs Procurement Notes

Verify the specific voltage rating (600 V or 800 V) required for your application, as the X02 series offers both options. Confirm that the TO-92 package and through-hole mounting method align with your PCB design constraints. Ensure the gate trigger current requirements fall within the specified 50 to 200 µA range for reliable operation.

Scrs Selection Notes

Select this component when a logic-level SCR is needed for AC switching with moderate current demands. The low gate trigger current makes it suitable for control circuits with limited drive capability. Consider the thermal-electrical characteristics if operating in high-temperature environments, ensuring the junction temperature remains within safe limits under load.

Scrs Part Context

The X02 series comprises logic-level SCRs designed for AC switching applications. These devices are optimized for performance in terms of forward voltage drop and inrush current handling. They are intended for use in systems where standard SCRs might require excessive gate drive current, providing a solution for low-power triggering scenarios.

Scrs Replacement Considerations

Check datasheets for alternative logic-level SCRs with similar I_T(RMS) and V_DRM ratings. Verify pinout compatibility for TO-92 packages. Ensure equivalent gate trigger current specifications to maintain circuit functionality without redesigning the gate drive network.

Scrs FAQ
