Product details
Overview
VO2601-X017T from Vishay Semiconductors is a single-channel, high-speed optocoupler with 10 MBd data rate, open-drain NMOS output, and enable-controlled strobing capability on pin 7. It integrates a high-efficiency GaAs LED input stage and monolithic photodiode + amplifier IC detector for isolated digital signal transmission in industrial PLCs, motor drives, and isolated UART interfaces.
For engineers reviewing the VO2601-X017T datasheet, VO2601-X017T pinout, VO2601-X017T application, or VO2601-X017T equivalent, key selection criteria include propagation delay (tpLH = 53 ns, tpHL = 42 ns), input threshold current (ITH = 5 mA), enable logic compatibility, and 5 V supply operation with external pull-up resistor support.
Technical Context
The VO2601-X017T implements a photodiode-based detection architecture with integrated transimpedance amplifier and NMOS output stage. Its enable pin (VE) controls output state via positive-logic gating, allowing synchronous strobing of received data without external logic.
It operates at 5 V supply, requires an external pull-up resistor on VO, and delivers rail-to-rail compatible output swing (VOL ≤ 1.5 V at IF = 7.5 mA). The device is characterized at Tamb = 25 °C with RL = 350 Ω and CL = 15 pF per simulation setup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10 MBd - supports high-speed serial isolation up to 10 million bits per second |
| Propagation Delay tpLH / tpHL | 53 ns / 42 ns - enables timing-critical applications such as isolated SPI clock domains | Input Threshold Current ITH | 5 mA - defines minimum LED forward current needed to guarantee low output transition |
| Output Type | Open-drain NMOS - requires external pull-up; supports wired-OR and level-shifting configurations |
| Enable Logic | Positive logic on pin 7 - high VE enables output, low VE forces high-impedance/high state |
| Supply Voltage | 5 V - designed for standard logic-level systems; no internal regulation |
Pinout & Package
VO2601-X017T is housed in an industry-standard 8-pin DIP package (0.300" wide) with gull-wing leads. Pin assignments are validated per Vishay PSpice model netlist and truth table documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DA) | Anode | LED anode input - connect to current-limited digital source or driver |
| 2 (DK) | Cathode | LED cathode - referenced to input-side ground |
| 5 (GND) | Detector Ground | Output-stage reference node - must be isolated from input ground |
| 6 (VO) | Output Drain | Open-drain NMOS output - requires external pull-up to VCC |
| 7 (VE) | Enable Input | Positive-logic enable - high = active output, low = high-Z/high |
| 8 (VCC) | Supply | +5 V power for detector IC - decoupling capacitor recommended |

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 | Same pinout, identical electrical specs, same enable function and NMOS output | No functional difference - direct drop-in replacement in legacy designs | Select when sourcing legacy-compatible footprint and documented qualification history is required |
| VO2611 | Identical VO2601-X017T die in alternate packaging (SO-8); same timing, ITH, and enable behavior | Requires PCB layout change due to surface-mount SO-8 vs. through-hole DIP | Choose for space-constrained boards where reflow assembly is preferred over wave soldering |
Compared with 6N137 and VO2611, VO2601-X017T offers identical high-speed performance and enable functionality but is specifically qualified in the DIP-8 through-hole package for serviceability and prototyping flexibility - making it optimal for industrial control modules requiring manual repair or field upgrades.

FAQ
What is the maximum data rate supported by VO2601-X017T?
The VO2601-X017T supports a maximum data rate of 10 MBd, verified under standard test conditions (VCC = 5 V, RL = 350 Ω, CL = 15 pF, Tamb = 25 °C). This rating reflects its capability to reliably transmit digital signals with minimal jitter and defined propagation delays (tpLH = 53 ns, tpHL = 42 ns), making VO2601-X017T suitable for high-speed isolated interfaces including UART, SPI, and encoder feedback paths.
Does VO2601-X017T require an external pull-up resistor on the output pin?
Yes, VO2601-X017T features an open-drain NMOS output (pin 6, VO) and requires an external pull-up resistor to VCC. The typical value used in characterization is 350 Ω, which sets the rise time and ensures VOL ≤ 1.5 V at IF = 7.5 mA. Without this resistor, VO remains floating in the high state, preventing proper logic-level interpretation - a design requirement explicitly noted in the VO2601-X017T truth table and simulation documentation.
How does the enable pin (VE) function on VO2601-X017T?
The enable pin (VE, pin 7) on VO2601-X017T uses positive logic: when VE is high, the output VO responds to LED input; when VE is low, VO enters high-impedance (high-Z) state regardless of LED condition. This behavior is confirmed in the truth table and PSpice netlist, where VE directly gates the detector's output stage. VO2601-X017T does not invert the enable signal - low VE forces VO high, matching the "H" output state in the truth table's third row.
What is the input threshold current (ITH) specification for VO2601-X017T?
The input threshold current (ITH) for VO2601-X017T is 5 mA, measured at VE = VO = 5 V with RL = 350 Ω. This parameter defines the minimum forward current through the internal GaAs LED required to guarantee a valid low-to-high or high-to-low output transition. It is a key design margin parameter for ensuring robust operation across temperature and aging - and is identical across VO2601-X017T, 6N137, and VO2611 per Vishay's PSpice modeling documentation.
Is VO2601-X017T pin-compatible with 6N137?
Yes, VO2601-X017T is pin-compatible with 6N137: both use the same DIP-8 package with identical pin assignments (DA=1, DK=2, GND=5, VO=6, VE=7, VCC=8). Their electrical characteristics - including ITH = 5 mA, tpLH = 53 ns, tpHL = 42 ns, and enable logic behavior - are identical per Vishay's unified PSpice model and truth table. VO2601-X017T is a Vishay-branded functional and mechanical replacement for 6N137 in new designs and legacy replacements.
