Overview
The Panasonic Electric Works APT1211S is a zero-cross switching solid-state relay in the APT1 series, designed for PCB mounting. It features an SOP-4 package with dimensions of 4.3 mm length. The device supports a maximum load voltage of 600 V and a maximum continuous output current of 50 mA. Control parameters include a typical forward voltage of 1.21 V and a maximum trigger current of 10 mA. Operating temperature ranges from -40°C to +100°C, with a maximum turn-on time of 100 µs.
Feature Summary
- Zero-cross switching functionality to reduce electrical noise
- Low zero-cross voltage design for enhanced noise reduction
- Triac output configuration for AC load control
Applications
- AC load switching in industrial control systems
- Solid-state relay applications requiring low noise operation
- PCB-mounted isolation circuits for AC power management
Procurement Notes
Verify the specific suffix 'S' indicates the SOP-4 package variant distinct from the standard DIP-4 APT1211. Confirm datasheet alignment for trigger current and package dimensions prior to integration. Ensure compliance with RoHS and safety certifications such as UL and VDE for the intended market.
Selection Notes
Select this component when low-profile SOP-4 packaging is required instead of the standard DIP format. The zero-cross feature is critical for minimizing electromagnetic interference in sensitive AC switching environments. Verify that the 50 mA continuous output current meets the load requirements.
Part Context
This part belongs to the Panasonic APT1 series of solid-state relays. The APT1211S specifically denotes the SOP-4 package version, differing from the APT1211 which uses a DIP-4 package. Both share similar electrical characteristics but differ in physical footprint and mounting style.
Replacement Considerations
The APT1211 serves as a direct functional substitute if the DIP-4 package is acceptable. Verify pinout compatibility and ensure the replacement matches the SOP-4 form factor if space constraints are critical.
FAQ
What is the difference between APT1211 and APT1211S?
The primary difference is the package type; APT1211 uses a DIP-4 package, while APT1211S uses an SOP-4 package.
Does the APT1211S support zero-cross switching?
Yes, it features zero-cross switching to minimize electrical noise during AC load activation.
