Quiver AI Summary

Vishay Intertechnology has launched the new Automotive Grade VOLA617A phototransistor optocoupler, designed for high galvanic isolation in electric vehicles (EVs) and industrial automation systems, particularly those using 800 V battery architectures. The device features an isolation voltage of 5000 VRMS, a VIORM of 1414 Vpeak, and a VIOTM of 8000 Vpeak, all in a 4-pin LSOP low profile package. It is suitable for various applications, including on-board chargers and battery management systems, standing out from typical automotive optocouplers which are limited to 500 V. The VOLA617A is rated for a broad temperature range, exhibits low coupling capacitance, and meets stringent Automotive Grade standards. Samples and production quantities are already available, with eight-week lead times.

Potential Positives

  • Introduction of the VOLA617A optocoupler enhances Vishay's portfolio with a product specifically designed for high voltage electric vehicles and industrial automation systems.
  • The VOLA617A's capability to handle voltages up to 1000 V allows Vishay to cater to next-generation 800 V battery architectures, positioning the company well in the EV market.
  • The device meets dual AEC-Q102 qualification standards, reinforcing its reliability and performance for automotive applications.
  • Vishay's commitment to sustainability is highlighted by the RoHS-compliant and halogen-free design of the VOLA617A, appealing to environmentally conscious manufacturers.

Potential Negatives

  • While the press release highlights the new optocoupler's capabilities, it lacks specific information on the competitive landscape, which could indicate that the company is facing significant competition in this area.
  • The mention of lead times of eight weeks for samples and production quantities may signal potential supply chain or production challenges that could affect customer satisfaction and revenues.
  • There is no mention of clear customer partnerships or existing contracts for the new product, raising concerns about market acceptance and demand for the VOLA617A.

Full Release

Device Offers Isolation Voltage of 5000 V RMS , V IORM of 1414 V peak , and V IOTM of 8000 V peak in 4-pin LSOP Low Profile Package

MALVERN, Pa., June 25, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new Automotive Grade phototransistor optocoupler designed to deliver signal transmission with high galvanic isolation for electric vehicles (EV) — including emerging 800 V battery architectures — and industrial automation systems. The Vishay Semiconductors VOLA617A combines an isolation voltage of 5000 V RMS with a V IORM of 1414 V peak and V IOTM of 8000 V peak in a 4-pin LSOP low profile package.

The device released today is ideal for grid-connected on-board chargers (OBC), DC/DC converters, battery management systems (BMS), isolated wake-up signals, and any system control with galvanic and noise isolation. While most automotive optocouplers can’t be used for battery voltages exceeding 500 V — limiting them to traditional 400 V EV platforms — the ability of the VOLA617A to isolate DC voltages up to 1000 V enables its use in next-generation high voltage EV architectures.

The VOLA617A consists of an infrared emitting diode, optically coupled to a silicon planar phototransistor detector in a low profile package with creepage and clearance distances of ≥ 8 mm. The device is available in four current transfer ratio (CTR) ranges and features a high 80 V collector-emitter voltage rating, allowing for more design flexibility.

The optocoupler operates over a wide -40 °C to +125 °C operating temperature — with a junction temperature capability up to +145 °C — while providing low coupling capacitance of 0.5 pF and high common mode transient immunity. Exceeding rigorous requirements for Automotive Grade performance and reliability, the VOLA617A’s robust package provides an extra safety margin by meeting dual AEC-Q102 qualification standards. The device is RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the VOLA617A are available now, with lead times of eight weeks.
