2N6394TG

Scrs Overview

The Littelfuse 2N6394TG is a surface mount SCR rated for a peak repetitive off-state voltage of 50 V and an on-state RMS current of 12 A. It features glass-passivated junctions and thermowatt construction for low thermal resistance. The device operates within a junction temperature range of -40 to +125 °C, with a maximum lead soldering temperature of 260 °C. Electrical characteristics include a typical gate trigger voltage of 1.5 V, a holding current of up to 50 mA, and a turn-off time of 15 µs at 25 °C. It is housed in a TO-220AB package.

Scrs Procurement Notes

Verify the specific ordering suffix 'TG' against the manufacturer's official documentation to confirm packaging details. The datasheet indicates this variant ships in boxes of 1000 units. Ensure compatibility with RoHS compliance requirements and confirm that the Pb-Free designation matches project specifications before finalizing procurement orders.

Scrs Selection Notes

Select the 2N6394TG when a 50 V blocking voltage and 12 A RMS current capacity are required for surface mount designs. Consider the 2.0 °C/W thermal resistance for heatsinking calculations. Verify that the 1.5 V gate trigger voltage aligns with the available drive circuit capabilities for reliable switching under varying temperature conditions.

Scrs Part Context

This component belongs to the 2N639x series of surface mount SCRs, which includes variants with blocking voltages ranging from 50 V to 800 V. All devices in this family share similar rugged thermowatt construction and glass-passivated junction technologies. The 2N6394G and 2N6394TG represent the 50 V rating options within this product line.

Scrs Replacement Considerations

Direct replacements within the same series include the 2N6394G, which shares identical electrical ratings and package dimensions. Other series members like the 2N6395 or 2N6397 offer higher voltage ratings but maintain the same physical footprint and thermal characteristics.
