ST35

Overview

The Littelfuse ST35 is a standard bidirectional DIAC trigger thyristor designed for phase control applications. It operates within a breakover voltage range of 30V to 40V at 50/60Hz sine wave conditions. The device features a maximum pulse on-state current of 2A and supports an operating junction temperature range from -40°C to +125°C. Packaged in the DO-214 (SMD) format, it utilizes high-quality junctions and white wafer selections to ensure reliable performance.

Feature Summary

Bidirectional triggering capability for full-wave phase control circuits
High-quality junction construction with white wafer selection
DO-214 surface-mount package design for space-saving integration

Applications

Lamp dimming circuits
Universal motor speed control systems
Heat control applications
Solid state ballast lighting controls

Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm packaging configuration and exact voltage tolerance ranges. Ensure compatibility with RoHS compliance requirements and lead-free soldering processes before finalizing procurement orders.

Selection Notes

Select the ST35 variant when a breakover voltage between 30V and 40V is required for triggering triacs or SCRs. Consider the DO-214 package dimensions for PCB layout constraints and verify thermal dissipation capabilities relative to the ambient operating temperature limits specified in the datasheet.

Part Context

The ST35 belongs to the HTxxx & HTMxxx & STxxx series of standard bidirectional DIAC triggers manufactured by Littelfuse under the Teccor brand. This series provides a comprehensive range of voltage characteristics from 27V to 70V, offering designers flexible options for various phase control and switching applications across different package formats.

Replacement Considerations

Compatible substitutes within the same family include ST32, ST34B, ST36A, ST36B, ST40, and ST60. These alternatives share identical DO-214 packaging and functional characteristics but differ in their specific breakover voltage ranges.
