It provides 5300 Vrms galvanic isolation between input and output sides, making it suitable for isolating digital logic interfaces in industrial motor drives, PLCs, and power-supply feedback loops. ## 5300 Vrms isolation and 5 kV/µs CMTI — what they mean for noisy environments The 5300 Vrms isolation rating qualifies this part for reinforced insulation in mains-connected equipment per IEC 60747-5-5. The 5 kV/µs minimum common-mode transient immunity ensures the output does not glitch when fast voltage transients couple across the isolation barrier — critical in variable-frequency drives and switch-mode power supplies where switching nodes swing hundreds of volts in nanoseconds. For a 5 V logic interface, the open-drain output with 50 mA per-channel sink capability can drive a terminated twisted pair or a standard CMOS load directly. ## Propagation delay and timing margin at 10 MBd With a maximum propagation delay of 100 ns for both low-to-high and high-to-low transitions, and typical rise/fall times of 23 ns and 7 ns respectively, the VO2631 supports 10 MBd NRZ signalling. The symmetrical tpHL/tpLH spec simplifies timing closure in bidirectional isolation channels — no need to budget asymmetric skew. The 100 ns max delay leaves comfortable margin for most 5 V logic families at 10 MHz clock rates, though for daisy-chained SPI isolators you may want to sum delays across the link. ## Active lifecycle, DIP-8 footprint, and sourcing posture Because this is a through-hole DIP-8 part, it remains a popular choice for prototyping, low-volume production, and legacy-board repairs where SMT rework is impractical. If you are evaluating a pin-compatible alternative, the HCPL-2631 from Broadcom (formerly Avago) shares the same footprint and 10 MBd open-drain specification, though always cross-check the forward current and isolation ratings against your design.","metaTitle":"VO2631 10MBd Dual-Channel Optocoupler, 5300Vrms, Open Drain","metaDescription":"VO2631 dual-channel optocoupler: 10 MBd data rate, 5300 Vrms isolation, open-drain outputs, 8-DIP through-hole.

Both are dual-channel 10 MBd optocouplers with open-drain outputs in an 8-DIP package. The VO2631 offers 5300 Vrms isolation versus the HCPL-2631's 3750 Vrms (typical), so verify your isolation voltage requirement before swapping. Forward voltage and current thresholds are similar, but always compare the datasheet limits for your operating conditions."},{"question":"What is the data rate of VO2631?","answer":"The VO2631 is rated for 10 MBd (megabaud) data rate, which corresponds to 10 Mbps NRZ signalling. With a maximum propagation delay of 100 ns and rise/fall times of 23 ns / 7 ns typical, it comfortably handles 10 MHz clocked interfaces like SPI or parallel bus isolators."},{"question":"Does VO2631 come in a surface mount package?","answer":"No, the VO2631 is only offered in a through-hole 8-DIP package (0.300 inch body width, 7.62 mm lead spacing). There is no surface-mount variant listed for this order code. For an SMT alternative, consider the VO2630 or VO2631-X017T (if available) in SOIC-8 wide-body, but confirm pin-compatibility and isolation ratings separately."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/VO2631","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/VO2631 when reusing this data.
