CYNB25-1200PT

Scrs Overview

The CYNB25-1200PT is a standard recovery silicon controlled rectifier (SCR) manufactured by Sensata-Crydom. It features a 1.2 kV off-state voltage rating and a 25 A average on-state current capacity. The device is housed in a TO-220AB package with through-hole mounting. Key electrical specifications include a non-repetitive surge current of 320 A at 50 Hz or 350 A at 60 Hz, and a maximum gate trigger voltage of 1.3 V. It operates within a temperature range of -40°C to 125°C.

Scrs Feature Summary

• Standard recovery SCR technology for reliable switching
• High surge current handling capability
• Through-hole TO-220AB package design

Scrs Applications

• Industrial power control systems
• Motor drive circuits
• Inverter applications

Scrs Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors as stock may be limited. Ensure the TO-220AB package dimensions match your PCB layout requirements. Validate that the 1.2 kV voltage rating meets your circuit's peak reverse voltage demands. Check for RoHS compliance documentation if required for your specific manufacturing standards.

Scrs Selection Notes

Select this part when a through-hole SCR with 1.2 kV blocking voltage and 25 A continuous current is required. Consider the TO-220AB package for ease of manual assembly or wave soldering. Evaluate the thermal management needs given the 125°C junction temperature limit. Compare surge ratings against potential inrush currents in the target application to ensure adequate safety margins.

Scrs Part Context

This component belongs to the Crydom thyristor family, designed for robust industrial applications. It serves as a discrete semiconductor switch for controlling AC power. The TO-220AB form factor allows for direct heatsinking. It is distinct from module-based SCRs like the M2540 series, offering a lower-power alternative for specific board-level designs.

Scrs Replacement Considerations

Public sources list this part as obsolete. No specific substitute part numbers are confirmed in the provided data. Engineers should consult manufacturer cross-reference guides for equivalent TO-220AB SCRs with matching 1.2 kV and 25 A ratings.
