MID400V

Overview

The MID400V is a logic output optocoupler designed for AC line monitoring applications. It features an open collector output and supports through-hole installation in an 8-DIP package. The device provides 2500 Vrms insulation voltage between input and output channels. Key electrical parameters include a maximum continuous output current of 20 mA, a forward current (If) of 30 mA, and a forward voltage (Vf) of 1.5 V. Power dissipation is rated at 115 mW. The component operates within a temperature range of -40°C to +85°C. Propagation delays are specified with typical values of 1 ms for both low-to-high and high-to-low transitions.

Feature Summary

• Optically isolated interface for converting AC line signals to logic levels
• Open collector output configuration for flexible interfacing
• High insulation voltage capability for safety isolation
• Certified by UR and VDE standards

Applications

• AC line monitoring systems
• Logic interface for AC power detection
• Safety isolation circuits requiring AC signal conversion

Procurement Notes

Verify the specific suffix variant against official datasheets, as packaging and mounting styles differ across the MID400 family. Confirm end-of-life status and obsolescence notices from onsemi before design finalization. Check RoHS compliance documentation for environmental regulations. Ensure the selected package matches the PCB footprint requirements, distinguishing between DIP and SMD variants. Validate that the application environment stays within the specified operating temperature range.

Selection Notes

Select this component when AC line monitoring requires galvanic isolation with logic-level output. Compare propagation delay specifications against system timing requirements. Evaluate thermal management needs based on the 115 mW power dissipation rating. Consider the open collector output drive capability for load matching. Verify that the 2500 Vrms isolation rating meets the safety standards required for the target application environment.

Part Context

The MID400V belongs to the MID400 series of optocouplers manufactured by onsemi. This series includes various packages such as PDIP and SMD options. The MID400V specifically utilizes an 8-lead plastic DIP package. It is part of a broader family of AC monitor-to-logic devices designed for industrial and consumer electronics applications requiring reliable AC signal detection.

Replacement Considerations

Public confirmed substitute part numbers include MID400TVM and MID400SDVM. These alternatives offer similar functionality but may differ in package type or mounting style. Verify pinout compatibility and electrical specifications before substitution.
