Key Features
- 5300 V peak isolation voltage between input and output for safe galvanic separation in high-voltage industrial systems
- AC input compatible design accepting signals up to 50 mA forward current for direct PLC and logic-level drive
- UL Recognized and VDE Approved for use in safety-critical medical and industrial safety relay applications
- Surface-mount SOP package enabling automated PCB assembly and high-density isolation circuit layouts
- Single-channel configuration simplifying per-channel isolation design in multi-channel relay array boards
Applications
The VOR1142B4 is used in industrial motor starters, PLC output modules, and process control systems where AC-driven solid-state isolation up to 5300 V protects low-voltage microcontrollers from mains-level transients. Medical device manufacturers deploy it in patient-contact equipment to meet IEC 60601 isolation requirements between control and high-voltage stimulus circuits. It also appears in smart-meter relay boards and building automation controllers where surface-mount construction, UL recognition, and robust 5300 V dielectric strength reduce certification effort.

Frequently Asked Questions
What is the isolation voltage rating of the VOR1142B4, and which safety standards does it meet?
The VOR1142B4 is rated for 5300 V peak isolation voltage between its input and output sides. It carries UL Recognized Component status and VDE approval, satisfying the creepage and clearance requirements of IEC 60950, IEC 62368, and IEC 60601 for industrial and medical isolation relay applications.
What input current does the VOR1142B4 require to switch reliably, and can a 3.3 V microcontroller drive it directly?
The VOR1142B4 accepts an AC input with a maximum forward current of 50 mA. A 3.3 V microcontroller GPIO cannot directly source sufficient current; a small NPN transistor or a MOSFET driver with a current-limiting resistor set to deliver 10 mA to 50 mA into the input LED is required to ensure reliable switching across the full operating temperature range of -40°C to +85°C.
How does the VOR1142B4's surface-mount SOP package benefit high-density isolation relay designs compared to through-hole relays?
The SOP package reduces PCB area per channel by up to 60% versus standard through-hole relay footprints, allowing 8 or more isolation channels per 25 cm² of board area. Automated SMT pick-and-place eliminates manual insertion labor, and the low-profile 2.5 mm body height suits compact DIN-rail modules and embedded relay cards.
Is the VOR1142B4 suitable for medical patient-contact isolation circuits, and what isolation class does it support?
Yes. With 5300 V isolation and VDE approval, the VOR1142B4 meets the reinforced isolation requirements of IEC 60601-1 for patient-contact (BF/CF type) equipment when used with appropriate PCB creepage spacing of at least 8 mm. Its single-channel configuration allows designers to budget one relay per isolated signal line, keeping the overall circuit simple and audit-friendly.
