Key Points

  • The VOLA617A optocoupler provides high isolation voltage ratings including 5000 VRMS and VIOTM of 8000 Vpeak, designed for 800 V EV battery platforms.
  • It supports critical automotive applications such as on-board chargers, DC/DC converters, and battery management systems by offering high reliability and meeting dual AEC-Q102 standards.
  • Operating across wide temperature ranges (-40°C to +125°C), the device ensures robust performance with low coupling capacitance and high transient immunity, aiding automotive and industrial sectors.

Device Offers Isolation Voltage of 5000 VRMS, VIORM of 1414 Vpeak, and VIOTM of 8000 Vpeak 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 VRMS with a VIORM of 1414 Vpeak and VIOTM of 8000 Vpeak 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.

Risks

  • Lead time of eight weeks could delay adoption in some production schedules, impacting supply chain responsiveness in automotive and industrial sectors.
  • Any unforeseen manufacturing or quality control issues with new device lines could affect product reliability and client trust, particularly critical for automotive safety applications.
  • Emergence of alternative isolation technologies or supplier innovations may limit market share growth for Vishay's new optocoupler, affecting competitive positioning in semiconductor components.
