ST36ARP

Overview

The ST36ARP is a DIAC thyristor manufactured by Littelfuse Inc., designed for triggering applications in power control circuits. It features a breakover voltage range of 32 to 40V and supports a peak output current of 2A. The device operates within a temperature range of -40°C to +125°C, with a maximum breakover current of 15 µA. Packaged in the DO-214AA (SMB) surface-mount format, it utilizes tape and reel packaging for automated assembly. This component is currently classified as obsolete.

Feature Summary

Symmetrical bidirectional switching capability for phase control applications
Surface-mount DO-214AA package design for compact circuit integration
High thermal stability supporting operation up to 125°C

Applications

Triac gate triggering circuits
Light dimmer controls
Motor speed regulation systems

Procurement Notes

Verify component availability status carefully as the ST36ARP is listed as obsolete. Confirm exact datasheet revisions when sourcing from distributors. Ensure replacement strategies account for end-of-life status. Validate package markings against official Littelfuse documentation to prevent counterfeit risks during procurement.

Selection Notes

Select this component only if legacy compatibility or specific historical design requirements necessitate its use. Consider modern alternatives due to obsolete status. Verify that the 32-40V breakover range matches the target circuit's triggering threshold. Ensure the SMB package footprint aligns with existing PCB layouts.

Part Context

The ST36ARP belongs to the DIAC/SIDAC category of discrete semiconductor products from Littelfuse Inc. It serves as a bilateral trigger device for thyristors and triacs. The component is part of Littelfuse's broader portfolio of protection and switching solutions, though this specific part number represents an older generation of surface-mount DIAC technology.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, engineers should consult Littelfuse technical support or authorized distributors for recommended cross-reference components that meet identical electrical specifications.
