Overview
The CS220-16B is a Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp, housed in a TO-220 case. It features a peak repetitive off-state voltage of 200 V and an RMS on-state current rating of 16 A at 90°C. The device supports a peak one-cycle surge current of 160 A with an I²t value of 128 A²s for fusing. Key electrical characteristics include a gate trigger current of up to 15 mA, a holding current of 20 mA, and a critical rate of rise of on-state current (di/dt) of 100 A/μs. Thermal resistance values are specified as 2.5 °C/W junction-to-case and 60 °C/W junction-to-ambient.
Feature Summary
- Epoxy molded construction designed for sensing circuit and control system applications
- High thermal efficiency with low junction-to-case thermal resistance
- Robust surge handling capability with defined I²t fusing values
Applications
- Sensing circuits
- Control systems
- Power switching applications requiring high surge tolerance
Procurement Notes
Verify the End of Life status before procurement planning. The manufacturer indicates that no replacement part numbers are available for this specific component. Last purchase orders must be placed within six months of the notice date, with final shipments occurring twelve months after the notice. Contact engineering support for potential alternate sourcing assistance if standard supply channels are exhausted.
Selection Notes
Select this component only if the application requires a 200 V blocking voltage and 16 A continuous current handling in a TO-220 package. Ensure the design accounts for the specified gate trigger parameters and thermal management requirements given the junction-to-ambient resistance. Confirm availability constraints due to the discontinued status before finalizing the bill of materials.
Part Context
This device belongs to the CS220 series of Silicon Controlled Rectifiers, which covers voltage ratings from 200 V to 800 V. All variants in this series share the same 16 A RMS on-state current rating but differ in their peak repetitive off-state voltage specifications. The series utilizes a standardized TO-220 mechanical outline for mounting compatibility across different voltage classes.
Replacement Considerations
No direct replacement part numbers are listed by the manufacturer for the CS220-16B. The datasheet explicitly states 'N/A' for all replacements in this series. Designers must evaluate alternative SCR manufacturers or redesign the circuit to accommodate currently available components with similar electrical ratings.
