Overview
The MID400SD is a single-channel logic output optocoupler designed for AC line monitoring applications. It features an open collector output and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum continuous output current of 20 mA, a forward current of 30 mA, and a forward voltage of 1.5 V. The device provides 2500 Vrms insulation voltage and has a power dissipation rating of 115 mW. It is housed in an 8-SMD surface-mount package.
Feature Summary
- Provides optical isolation between AC line voltage and logic circuits
- Features open collector output suitable for direct logic interface
- Designed for high-speed data transmission up to 10 MBit/s
Applications
- AC line monitoring systems
- Logic gate applications requiring electrical isolation
- Fast data transmission interfaces
Procurement Notes
Verify the specific suffix (SD) against the official onsemi datasheet to confirm the 8-SMD package configuration. Confirm RoHS compliance status through the manufacturer's documentation. Check for end-of-life or limited availability status as indicated by distributor records. Ensure the ordering part number matches the required tape and reel or cut tape packaging format specified in the procurement requirements.
Selection Notes
Select this component when an AC line monitor with logic output is required. Ensure the system design accommodates the 2500 Vrms isolation requirement. Verify that the 20 mA output current capability meets the load requirements. Consider the SMD-8 package constraints for PCB layout. Confirm operating temperature range suitability for the intended environment.
Part Context
The MID400SD belongs to the MID400 series of optically isolated AC line-to-logic interface devices manufactured by onsemi. This series includes variants such as the MID400M, which offers similar functionality in a DIP package. The device serves as a specialized isolator for converting AC line signals to compatible logic levels while maintaining electrical safety separation.
Replacement Considerations
The MID400S is a related variant within the same family. Verify pinout and package compatibility before substitution. Consult the official datasheet for detailed electrical parameter comparisons between the SD and other series members.
