Overview
The SFH690ABT is a single-channel transistor output optocoupler from Vishay. It features a GaAs infrared emitting diode optically coupled to a silicon planar phototransistor detector. The device provides 3750Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a DC forward current of 50mA, and a typical forward voltage of 1.15V to 1.4V. The current transfer ratio ranges from 50% to 300% at 5mA input. Switching characteristics include typical rise and fall times of 3µs and 4µs respectively, with a saturation voltage of 300mV maximum.

Procurement Notes
Verify the specific suffix 'ABT' corresponds to the required Current Transfer Ratio (CTR) bin, as the SFH690 family includes variants with different CTR specifications. Confirm RoHS compliance status and REACH registration details with the manufacturer or authorized distributor prior to final procurement. Ensure the ordering quantity matches the standard reel or cut tape packaging options available.
Selection Notes
Select this component when a low-cost, general-purpose transistor output isolator is required. The SFH690ABT offers a balance of speed and isolation voltage. Consider the CTR variation (50-300%) when designing bias networks to ensure reliable switching across all units. Verify that the 70V collector-emitter voltage meets the load requirements of the isolated circuit side.
Part Context
The SFH690ABT belongs to the SFH690 series of surface-mount optocouplers manufactured by Vishay Semiconductor Opto Division. This series utilizes a GaAs infrared emitter paired with a silicon phototransistor. The 'ABT' designation specifically identifies the CTR binning and packaging configuration within the broader SFH690 product line, which also includes variants like SFH690AT, BT, CT, and DT.
Replacement Considerations
Direct replacements within the same family include SFH690AT, SFH690BT, SFH690CT, and SFH690DT. These parts share identical pinouts and mechanical dimensions but may differ in Current Transfer Ratio (CTR) specifications. Verify that the CTR range of the substitute part aligns with the design requirements before substitution.
