Product details
Overview
VOR1142B4 from Vishay Semiconductors is a 400 V, 140 mA single-channel normally open optically isolated solid-state relay (SPST, Form A) with 22 Ω typical on-resistance, 5300 VRMS isolation voltage, and SMD-4 package. It uses a GaAlAs IRED input and high-performance MOSFET output to switch DC/AC loads in telecom switching, metering, and industrial control systems.
For engineers reviewing the VOR1142B4 datasheet, VOR1142B4 pinout, VOR1142B4 application, or VOR1142B4 equivalent, this page delivers verified electrical specs, safety-rated insulation data, timing characteristics, thermal derating curves, and real-world use context for reliable system-level integration.
Technical Context
The VOR1142B4 integrates an infrared LED input stage coupled via optical isolation to a high-voltage MOSFET output stage. Its hybrid architecture enables clean bounce-free switching with 0.13 ms typical turn-on and 0.05 ms typical turn-off times at IF = 5 mA and IL = 50 mA.
It complies with UL, cUL, and DIN EN 60747-5-5 (VDE 0884-5) safety standards, featuring 8 mm creepage/clearance, ≥0.4 mm insulation thickness, and 890 Vpeak maximum repetitive peak isolation voltage (VIORM), supporting safe operation in reinforced insulation applications up to 400 V load voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Load Voltage | 400 V DC or peak AC - supports mains-connected switching in metering and industrial controls without external snubbers. |
| Continuous Load Current | 140 mA at 25 °C - sufficient for driving relays, solenoids, and low-power AC/DC loads in automated test equipment. |
| On-Resistance (RON) | 22 Ω typical - limits power dissipation to ≤550 mW at rated current, enabling compact PCB layout without forced cooling. |
| Isolation Voltage | 5300 VRMS - meets reinforced insulation requirements per UL1577 and VDE 0884-5 for safety-critical isolation barriers. |
| Ambient Temperature Range | −40 °C to +100 °C - validated for operation in harsh environments including battery management systems and outdoor security equipment. |
| Turn-On / Turn-Off Time | 0.13 ms / 0.05 ms typical - enables precise timing control in high-speed automatic test equipment and programmable logic interfaces. |
| Input Forward Current (IFon) | 0.25 mA typical - allows direct drive from low-power microcontrollers or logic outputs without external amplification. |
Pinout & Package
SMD-4 surface-mount package (7.62 mm × 6.65 mm × 2.54 mm height), RoHS-compliant, moisture sensitivity level 1, lead-free reflow compatible per J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VOR1142B1 | Tape-and-reel packaging (VOR1142B4T), identical electrical specs and SMD-4 footprint. | No difference in circuit function or board layout; differs only in packaging format and reel quantity (1000 vs. tube). | Select VOR1142B1 for automated SMT assembly; VOR1142B4 remains optimal for prototyping, repair, or low-volume hand-soldering. |
| VO1263AD | Lower load voltage (240 V), higher RON (35 Ω typical), same 140 mA rating and SMD-4 package. | Not suitable for 400 V AC mains applications; limited to sub-240 V DC/AC systems like automotive body control or lab equipment. | Choose VO1263AD only when 400 V capability is unnecessary and cost sensitivity outweighs voltage margin requirements. |
Compared with VOR1142B4, VOR1142B1 offers identical performance in tape-and-reel form for production lines, while VO1263AD trades 400 V capability for lower cost in lower-voltage applications-neither is pin-compatible nor drop-in; both require validation against load voltage, thermal, and safety constraints.

FAQ
What is the maximum load voltage rating for the VOR1142B4?
The VOR1142B4 is rated for a maximum DC or peak AC load voltage of 400 V. This rating is validated per absolute maximum specifications and supported by safety certifications including UL, cUL, and DIN EN 60747-5-5. Operation above this voltage risks permanent device failure and violates isolation barrier integrity. The VOR1142B4 must not be used in circuits where transient overvoltages exceed 400 V without external clamping.
Does the VOR1142B4 support bidirectional AC load switching?
Yes, the VOR1142B4 supports bidirectional AC load switching due to its MOSFET-based output stage with symmetrical pin 3 (source) and pin 4 (drain) configuration. Electrical characteristics specify performance under ±350 V load conditions, and the device is explicitly characterized for AC/DC operation in the datasheet's RON and leakage current tables. No external polarity protection is required for standard AC line switching.
What is the minimum input forward current needed to reliably turn on the VOR1142B4?
The VOR1142B4 requires a minimum input forward current of 0.05 mA (typical 0.25 mA, max 2 mA) to achieve guaranteed turn-on within 10 ms at 100 mA load current. This low drive threshold allows direct interfacing with microcontroller GPIOs, open-collector logic, or low-power comparators without additional driver stages. At 0.25 mA, the device achieves full specification timing and RON performance across its operating temperature range.
Can the VOR1142B4 replace an electromechanical relay in a high-cycle application?
Yes, the VOR1142B4 is specifically designed to replace electromechanical relays in high-cycle applications such as automatic test equipment and programmable logic controllers. With no moving parts, it delivers bounce-free switching, >10⁶ operational cycles, and immunity to vibration and contact wear. Its 0.13 ms turn-on and 0.05 ms turn-off times further enable precise timing control unattainable with mechanical counterparts.
Is the VOR1142B4 compliant with RoHS and REACH regulations?
Yes, the VOR1142B4 is RoHS-compliant (lead-free) and conforms to REACH SVHC requirements as confirmed in Vishay's official compliance documentation (www.vishay.com/doc?99912). The SMD-4 package uses matte tin terminations, and the device meets J-STD-020 reflow profiles. Material categorization is defined per Vishay document 99912, and full substance declarations are available upon request through Aetrix Electronics' technical support.
