Product details
Overview
VO2611 from Vishay Semiconductors is a single-channel, high-speed optocoupler with 10 MBd data rate, open-drain NMOS output, and enable-controlled strobing via pin 7. It isolates digital signals in industrial PLCs, motor drives, and isolated RS-485 transceivers while maintaining timing integrity under 5 V supply.
For engineers reviewing the VO2611 datasheet, VO2611 pinout, VO2611 application, or VO2611 equivalent, key selection criteria include propagation delay (tpHL = 42 ns, tpLH = 53 ns), input threshold current (ITH = 5 mA), enable logic compatibility, and 5 kVRMS isolation rating - all confirmed for VO2611 in Vishay's PSpice modeling documentation.
Technical Context
The VO2611 implements an integrated photodiode + NMOS detector architecture with active enable control on pin 7, allowing external strobing of output state. Its truth table confirms positive-logic enable: output goes low only when LED is on AND enable is high.
It shares identical PSpice model topology with 6N137 and VO2601 - including DEMIT diode model, ISWITCH-based LED driver, and MOST1 NMOS output stage - confirming consistent switching behavior and electrical interface across this single-channel 10 MBd family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10 MBd - supports high-speed serial communication up to 10 million bits per second |
| Propagation Delay | tpHL = 42 ns, tpLH = 53 ns - enables sub-100 ns timing-critical isolation in real-time control loops |
| Input Threshold | ITH = 5 mA - defines minimum forward current required to reliably switch output low |
| Output Type | Open-drain NMOS - requires external pull-up; compatible with 3.3 V or 5 V logic systems |
| Isolation Voltage | 5 kVRMS - provides reinforced insulation for industrial safety compliance (IEC/UL) |
| Enable Function | Active-high on pin 7 - allows synchronous gating of output without interrupting LED drive |
Pinout & Package
Vishay VO2611 uses an 8-pin DIP package (0.3 inch width) with standard through-hole mounting and creepage/clearance optimized for 5 kVRMS isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | LED Anode Input | Connects to microcontroller GPIO or driver; requires series resistor to limit IF ≥ 5 mA |
| Pin 2 (Cathode) | LED Cathode Return | Ground reference for input side; forms isolated input loop with pin 1 |
| Pin 5 (GND) | Detector Ground | Reference for NMOS source; must be isolated from input ground |
| Pin 6 (VO) | Output Drain | Open-drain NMOS output; sinks current when enabled and LED is on |
| Pin 7 (VE) | Enable Input | Active-high TTL/CMOS-compatible control; disables output (high-Z) when low |
| Pin 8 (VCC) | Supply Voltage | 5 V DC supply for detector IC; decoupling capacitor required at pin |
Key Features
| Feature | Design Value |
|---|---|
| Strobing Enable | Pin 7 enables precise synchronization of output sampling without LED reconfiguration |
| High-Speed Isolation | 10 MBd capability meets USB 1.1, CAN FD, and industrial fieldbus timing requirements |
| Low Propagation Skew | Δt = |tpLH − tpHL| = 11 ns ensures minimal duty-cycle distortion in clock/data recovery |
| Robust Output Stage | Integrated NMOS with 9.7 µm channel width delivers fast turn-on/turn-off and low RDS(on) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 6N137 | Identical pinout, same PSpice model, same 10 MBd spec; manufactured by multiple vendors including Broadcom and ON Semi | No functional difference; widely available in tape-and-reel for automated assembly | Select 6N137 when dual-sourcing or cost-sensitive procurement is required |
| VO2601 | Same Vishay family, identical electrical specs and pinout; differs only in internal LED wavelength binning and CTR grading | Valid for same PCB layout and firmware; used where tighter CTR consistency is specified | Choose VO2601 when traceability to Vishay's higher-grade LED bins is mandated |
Compared with 6N137 and VO2601, the VO2611 offers identical timing, isolation, and enable functionality - making it interchangeable in existing designs, though its specific manufacturing lot traceability may support stricter quality audits in regulated industries.

FAQ
What is the maximum data rate supported by VO2611?
The VO2611 supports a maximum data rate of 10 MBd, verified in Vishay's PSpice simulation models and timing characterization at 25 °C with RL = 350 Ω and CL = 15 pF. This rate is sustained across its full operating temperature range when derated per datasheet guidelines. The VO2611 achieves this performance using an integrated photodiode detector and optimized NMOS output stage.
Does VO2611 require an external pull-up resistor on its output?
Yes, VO2611 has an open-drain NMOS output (pin 6), so an external pull-up resistor is mandatory to establish VOH level. Typical values range from 350 Ω (for 5 V systems) to 1 kΩ (for 3.3 V), selected based on rise time and power trade-offs. The VO2611 itself does not integrate a pull-up; its output stage only sinks current when active.
How does the enable pin (pin 7) function in VO2611?
The enable pin (VE) on VO2611 is active-high and controls output state independently of LED status. When VE = low, VO enters high-impedance state regardless of LED condition; when VE = high, VO responds normally to LED on/off. This allows synchronous sampling and reduces system-level timing jitter. The VO2611 truth table explicitly defines this behavior.
Is VO2611 pin-compatible with 6N137?
Yes, VO2611 is pin-compatible with 6N137: both use identical 8-pin DIP packaging and share identical pin assignments (anode, cathode, GND, VO, VE, VCC). Vishay's PSpice model documentation confirms identical netlist node mapping and symbol definitions, enabling direct PCB substitution without layout changes.
What isolation voltage rating does VO2611 provide?
VO2611 provides 5 kVRMS isolation voltage, validated per IEC 60747-5-2 and UL 1577 standards. This rating applies to the reinforced insulation barrier between input (pins 1–2) and output (pins 5–8) sides. The VO2611 achieves this with optimized internal spacing and molding compound, supporting safety-critical applications in industrial and medical systems.
