Product details
Overview
VO14642AABTR from Vishay Semiconductors is a high-speed, single-channel, normally open solid-state relay (SPST, Form A) in a DIP-6 package, integrating an infrared LED input and high-performance MOSFET output stage. It delivers <800 μs turn-on/turn-off times, 0.25 Ω maximum on-resistance (AC/DC), 5300 VRMS isolation voltage, 60 V load voltage rating, and supports up to 2 A DC load current - used for bounce-free switching in industrial control signal isolation.
For engineers reviewing the VO14642AABTR datasheet, VO14642AABTR pinout, VO14642AABTR application, or VO14642AABTR equivalent, this device is selected for low-RON, TTL/CMOS-compatible optically isolated switching where AC/DC or DC-only load configurations are required, and safety-rated insulation (UL 1577, VDE 0884-5) is mandatory.
Technical Context
The VO14642AABTR uses a multi-chip hybrid construction with an efficient infrared LED driving a high-voltage MOSFET output stage. Its dual-mode operation (AC/DC or DC-only) is enabled by internal configuration - no external components needed - and it achieves clean, bounce-free switching via zero-crossing–independent MOSFET control logic.
Isolation performance meets UL 1577 (5300 VRMS, 1 min), DIN EN 60747-5-5 (VIORM = 890 Vpeak), and includes ≥7 mm creepage/clearance with ≥0.4 mm insulation thickness. Thermal design relies on θEB = 176 °C/W (junction emitter to board) and θDB = 67 °C/W (junction detector to board), supporting operation from –55 °C to +85 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode input - connect to MCU GPIO or driver with current-limiting resistor (IF ≤ 50 mA). |
| 2 | Cathode | LED cathode input - referenced to system ground; defines input polarity and logic-active low capability. |
| 3 | NC | No connection - internally unconnected; must remain floating, not tied to any net. |
| 4 | Load | Output source terminal - connects to positive side of load (e.g., solenoid, lamp, relay coil). |
| 5 | Load | Output sink terminal - connects to return path (ground or negative rail); completes MOSFET output loop. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS CPC1976Y | Higher RON (0.35 Ω max), same DIP-6 package, 4000 VRMS isolation, 1.5 A DC rating. | Limited to lower-current loads; lacks DC-only configuration pin; requires higher IF for turn-on. | Select when lower cost is prioritized over 2 A capability and dual-mode flexibility. |
| Infineon IL420 | Triac-based AC-only SSR, 400 V blocking, 100 mA load current, SO-6 package, no DC capability. | Not suitable for DC loads or mixed AC/DC operation; limited to low-power AC switching only. | Choose only for pure AC mains switching where DC operation is unnecessary and space constraints favor SMD. |
Compared with VO14642AABTR, CPC1976Y offers reduced isolation and current handling but lower unit cost, while IL420 provides AC-specific triac switching in a smaller footprint but cannot replace VO14642AABTR in DC or dual-mode applications.

FAQ
What is the maximum load current rating for VO14642AABTR in DC-only mode?
The VO14642AABTR supports up to 2 A DC load current when configured for DC-only operation (Pin 6 grounded). This rating is validated at Tamb = 25 °C and derates linearly above 25 °C per the absolute maximum ratings curve in the datasheet. At 85 °C ambient, the usable DC load current drops to approximately 1.2 A to maintain safe junction temperatures.
Does VO14642AABTR support AC load switching, and what is its AC voltage limit?
Yes, VO14642AABTR supports AC/DC load operation with a maximum load voltage of 60 V - applicable to both DC and peak AC values. For sinusoidal AC, this corresponds to ~42 V RMS. The device uses MOSFET output architecture (not triac), so it conducts bidirectionally only when externally configured with back-to-back MOSFETs - VO14642AABTR itself is unidirectional and intended for DC or half-wave rectified AC loads unless paired with external circuitry.
How is the VO14642AABTR pinout configured for AC/DC versus DC-only operation?
VO14642AABTR uses Pin 6 (labeled "DC") to select operating mode: leave Pin 6 open for AC/DC mode (default), or tie Pin 6 to ground for DC-only mode. In DC-only mode, on-resistance improves to 0.07 Ω max (vs. 0.25 Ω in AC/DC mode), enhancing efficiency for continuous DC loads like solenoids and valves.
What safety certifications does VO14642AABTR hold, and under what conditions are they valid?
VO14642AABTR is certified to UL 1577 (5300 VRMS, 1 min), cUL, DIN EN 60747-5-5 (VDE 0884-5), and FIMKO. These approvals are valid only for operation within the ambient temperature range of –40 °C to +85 °C. Certification covers reinforced insulation with ≥7 mm creepage/clearance and ≥0.4 mm insulation thickness, meeting IEC 61010-1 requirements for measurement category II equipment.
Can VO14642AABTR be used with 3.3 V microcontroller GPIOs without additional circuitry?
Yes, VO14642AABTR is TTL/CMOS compatible and can be driven directly by 3.3 V or 5 V logic outputs. With a typical LED forward voltage of 1.4 V and minimum turn-on current of 0.5 mA, a series resistor of ~4.7 kΩ suffices for 3.3 V drive - delivering ~0.57 mA IF, which exceeds the guaranteed turn-on threshold. No level shifter or buffer IC is required.
