Vishay Intertechnology today introduced the VOx619A series of phototransistor optocouplers, a new line engineered for high‑temperature, low‑forward‑current operation. The devices deliver a 0.5 mA forward current, a current‑transfer ratio (CTR) exceeding 75 % across a temperature range up to +125 °C, and isolation voltages of 5000 VRMS in DIL‑4 and LSOP‑4 packages and 3750 VRMS in SOP‑4 and SSOP‑4 packages. The series is available in four compact packages—DIL‑4, LSOP‑4, SOP‑4, and SSOP‑4—providing design flexibility for space‑constrained boards while cutting forward current by 50 % compared with the previous generation.
The VOx619A’s performance gains are driven by a new silicon‑on‑insulator (SOI) design that reduces junction leakage and improves thermal stability. The 75 % CTR at +125 °C outpaces the 65 % CTR typical of earlier Vishay optocouplers, enabling reliable operation in harsh industrial and automotive environments. The 5000 VRMS isolation in the larger packages meets the stringent safety requirements of power‑management and telecom applications, while the 3750 VRMS rating in the smaller SOP and SSOP packages keeps the series attractive for consumer and energy‑metering devices.
The optocoupler market is projected to grow from USD 3.26 billion in 2026 to USD 5.08 billion by 2031, a CAGR of 9.29 %. The phototransistor segment, which accounts for 31.85 % of the market, is expanding fastest in industrial automation and automotive/e‑mobility sectors, where high‑temperature, low‑power isolation is critical. Vishay’s new series positions the company to capture a share of this growth, competing with players such as ON Semiconductor, Toshiba, Broadcom, and Renesas Electronics. By offering a lower‑current, higher‑temperature product, Vishay addresses a key headwind—thermal stress in SiC‑based traction inverters—while reinforcing its foothold in energy‑efficient signal isolation.
Strategically, the VOx619A launch aligns with Vishay’s “Vishay 3.0” initiative, which seeks to accelerate revenue growth, enhance profitability, and broaden the company’s high‑performance, low‑power portfolio. The new optocouplers complement Vishay’s existing discrete semiconductor offerings and support the company’s focus on industrial automation, micro‑mobility, and power‑management markets. The eight‑week lead time for samples and production units signals a rapid go‑to‑market capability that can help Vishay secure early orders from key customers in the automotive and industrial sectors.
The introduction of the VOx619A series is expected to strengthen Vishay’s revenue mix by adding a high‑margin, high‑volume product line that serves both existing and emerging markets. While the launch itself may not immediately shift quarterly earnings, it expands the company’s product breadth and positions Vishay to capture demand from energy‑efficient, high‑temperature applications. The strategic emphasis on low‑forward‑current, high‑temperature optocouplers reflects broader industry trends toward sustainability and miniaturization, and it signals Vishay’s intent to maintain a competitive edge in a rapidly evolving market.
