Overview
The S4016R is a standard phase control silicon controlled rectifier (SCR) from Littelfuse, rated for 400V repetitive peak off-state voltage and 16A average on-state current. It features a non-isolated TO-220 package suitable for through-hole mounting. Key electrical parameters include a maximum holding current of 40 mA and a non-repetitive on-state surge current capability of 225 A. The device is designed for low-power applications requiring reliable switching in phase control circuits.
Feature Summary
- Electrically isolated package option available within the series
- Low gate trigger current requirement for efficient control
- Standard recovery characteristics optimized for phase control
Applications
- Heating element control systems
- Motor speed control circuits
- General purpose phase control devices
Procurement Notes
Verify the specific suffix against the official Littelfuse datasheet to confirm pinout and isolation status. Ensure the ordered component matches the required voltage and current ratings for the target application. Confirm RoHS compliance status if environmental regulations apply to the end product.
Selection Notes
Select this component for applications requiring robust phase control with moderate current handling. Compare holding current specifications against the load requirements to ensure reliable latching. Consider thermal management solutions appropriate for the TO-220 package when designing the heat dissipation strategy.
Part Context
This SCR belongs to the Low Power SCR series up to 1200V, designed specifically for heating and motor speed control applications. The series emphasizes ease of triggering with minimal gate current, making it suitable for cost-sensitive industrial and consumer electronics where standard phase control is required.
Replacement Considerations
Cross-reference with other 400V 16A SCRs in the TO-220 package. Verify that substitute parts meet or exceed the 40 mA holding current and 225 A surge current specifications to maintain circuit performance.
