2N6565AP

Scrs Overview

The Littelfuse 2N6565AP is a sensitive silicon-controlled rectifier (SCR) from the Teccor line, designed as a half-wave unidirectional gate-controlled rectifier. It features an electrically isolated TO-220 package with a maximum repetitive peak off-state voltage of 400 V and an average on-state current rating of 0.8 A at 25 °C. The device exhibits high gate sensitivity with a maximum DC gate trigger current of 200 µA and a peak one-cycle forward surge current capability of 100 A. Constructed with glass-passivated junctions for parameter stability, it operates within a junction temperature range of -65 °C to +125 °C.

Scrs Feature Summary

• Electrically isolated TO-220 package allowing direct mounting to heatsinks without external insulators
• Glass-passivated chip construction providing a rugged barrier against junction contamination
• High gate sensitivity suitable for low-power control circuits

Scrs Applications

• Phase control applications requiring sensitive gate drive
• AC switching circuits with isolation requirements
• Temperature modulation controls

Scrs Procurement Notes

Verify the specific suffix 'AP' against official Littelfuse documentation to confirm if it denotes a distinct electrical variant or packaging configuration compared to the standard 2N6565. Ensure the ordered component matches the required electrical isolation rating of 2500 V rms from leads to mounting tab. Confirm package dimensions align with the intended PCB layout constraints.

Scrs Selection Notes

Select this component when a sensitive SCR with 400 V blocking capability and 0.8 A current handling is required in an isolated package. Consider the thermal resistance characteristics for heat dissipation design. Evaluate the gate trigger current specifications to ensure compatibility with the available control circuit drive strength.

Scrs Part Context

The 2N6565AP belongs to the JEDEC registered 2N Series within the Teccor sensitive SCRs product line. This series complements higher power SCRs by offering lower current ratings with enhanced gate sensitivity. The device shares common family features such as glass passivation and standardized JEDEC testing conditions.

Scrs Replacement Considerations

Direct replacements include other 2N6565 variants with identical electrical ratings. Verify that any substitute maintains the same TO-220 isolated package form factor and 400 V voltage rating.
