2N6395G

Scrs Overview

The Littelfuse 2N6395G is a surface mount silicon-controlled rectifier (SCR) designed for half-wave AC control applications. It features glass-passivated junctions and rugged Thermowatt construction for low thermal resistance and high heat dissipation. The device operates with a peak repetitive off-state voltage of 100 V and supports an on-state RMS current of 12 A at a case temperature of 90°C. It withstands a peak non-repetitive surge current of 100 A. The component functions within an operating junction temperature range of -40 to +125°C and utilizes a TO-220AB package.

Scrs Procurement Notes

Verify the specific part number against the manufacturer's official datasheet to confirm electrical ratings and package style before ordering. Ensure that the procurement specifications align with the required blocking voltage and current capabilities for the intended circuit design. Confirm lead-free status if environmental compliance is mandatory for the application.

Scrs Selection Notes

Select this component based on the required 100 V blocking voltage and 12 A RMS current rating. Consider the thermal resistance characteristics when designing the heatsinking strategy, as the device dissipates significant heat during operation. Verify that the gate trigger requirements match the driving circuit capabilities to ensure reliable turn-on under all operating conditions.

Scrs Part Context

The 2N6395G belongs to the 2N639x series of surface mount thyristors from Littelfuse. This family includes variants with different voltage ratings, such as the 2N6394 (50 V), 2N6397 (400 V), and 2N6399 (800 V). All devices in the series share similar physical dimensions and thermal characteristics, allowing for flexible design options within the same footprint constraints.

Scrs Replacement Considerations

Direct replacements include other 2N639x series parts with matching or higher voltage ratings, such as the 2N6397G or 2N6399G, provided the lower voltage does not impact circuit functionality. Cross-brand equivalents must be verified for identical pinout, thermal resistance, and electrical performance parameters.
