Overview
The onsemi 4N29SD is a single-channel transistor output optocoupler featuring a photodarlington detector. It utilizes surface mount technology in a 6-SMD, Gull Wing package. Key electrical specifications include a collector-emitter voltage of 30 V and a maximum collector current of 150 mA. The device provides an isolation voltage of 5300 Vrms. It operates within a temperature range of -40°C to +100°C and has a power dissipation rating of 250 mW.
Feature Summary
- Photodarlington output configuration for high gain
- Surface mount 6-pin gull wing packaging
- High insulation voltage capability
Applications
- General purpose signal isolation
- Logic circuit interfacing
- Industrial control systems
Procurement Notes
Verify the specific suffix 'SD' against the manufacturer's official datasheet to confirm the SMD package variant. Confirm end-of-life status with the supplier prior to procurement. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Validate that the 5300 Vrms isolation rating meets system safety requirements.
Selection Notes
Select this component when a surface mount solution is required for applications needing high current transfer ratio from a phototransistor output. Compare against through-hole variants like the 4N29TM if board space allows. Verify that the 30 V collector-emitter voltage is sufficient for the load circuit. Consider the operating temperature range for environmental constraints.
Part Context
This part belongs to the 4N29 series of optocouplers produced by onsemi. It shares functional similarities with other devices in the family but differs in package type. The SD suffix typically denotes the surface mount version, distinguishing it from the through-hole PDIP-6 packages found in other series members.
Replacement Considerations
Check for direct pin-compatible surface mount replacements from onsemi or other manufacturers. Verify that substitute parts maintain the 5300 Vrms isolation and photodarlington output characteristics. Ensure the replacement supports the same 6-SMD gull wing footprint.
