2N6395

Scrs Overview

The onsemi 2N6395 is a silicon controlled rectifier (SCR) from the 2N6394 Series, designed for half-wave AC control applications. It features glass passivated junctions with center gate geometry for parameter uniformity and stability. The device operates in a TO-220AB package with a maximum repetitive off-state voltage of 100 V and an RMS on-state current of 12 A at a case temperature of 90°C. It supports a peak non-repetitive surge current of 100 A and has a thermal resistance from junction to case of 2.0 °C/W. The component is lead-free and functions within a junction temperature range of -40°C to +125°C.

Scrs Feature Summary

• Glass passivated junctions with center gate geometry ensure greater parameter uniformity and stability.
• Thermowatt construction provides low thermal resistance, high heat dissipation, and durability.
• Lead-free packaging meets environmental standards.

Scrs Applications

• Motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package style and shipping quantity. The standard bulk configuration contains 500 units per container. Confirm that the Pb-Free designation aligns with project requirements. Ensure the selected variant matches the required blocking voltage rating for the intended circuit application.

Scrs Selection Notes

Select this component when a 100 V blocking voltage SCR is required for half-wave AC control circuits. Evaluate the 12 A RMS current capability against the load requirements at the expected operating case temperature. Consider the 2.0 °C/W thermal resistance for heatsink design calculations. Verify compatibility with the TO-220AB mounting style and pin assignment for the target PCB or chassis layout.

Scrs Part Context

The 2N6395 belongs to the 2N6394 Series of reverse blocking thyristors manufactured by onsemi. This series includes variants with different voltage ratings: 2N6394 (50 V), 2N6395 (100 V), 2N6397 (400 V), and 2N6399 (800 V). All devices share identical current ratings and physical package dimensions, differing primarily in their peak repetitive off-state voltage specifications.

Scrs Replacement Considerations

Direct functional substitutes within the same series include the 2N6394, 2N6397, and 2N6399, provided the lower voltage rating of the 2N6394 or the higher voltage rating of the other variants does not compromise circuit safety margins. Cross-manufacturer replacements must match the 12 A RMS current, 100 V blocking voltage, and TO-220AB package constraints.
