Vishay VIA isolation amplifiers: a second source to ensure supply continuity
High-precision motion control with Bogen Magnetics’ miniaturized sensors
Is your design ready to ensure supply continuity?
In today’s power electronics landscape, the rapid expansion of AI infrastructure, data centers, EV chargers, photovoltaic inverters, and industrial automation has sharply increased demand for key components. As a result, many manufacturers are facing serious supply chain strain for isolation amplifiers, compromising lead times and the continuity of their production lines.
Relying on a single supplier for critical projects exposes companies to risks such as allocation constraints, cost increases, and production stoppages. Qualifying a second semiconductor source is not just a risk‑mitigation strategy — it is an essential requirement to safeguard supply continuity. Having pin‑to‑pin qualified alternatives allows fast reaction without the need to redesign printed circuit boards (PCBs).
Vishay VIA family: continuity without compromising quality
The Vishay VIA family offers a reinforced isolation solution designed for demanding industrial applications. Its devices provide functional and pin‑to‑pin compatibility with widely used market references, making it easier to qualify a second source when availability is critical. In addition, the family stands out for its high transient immunity, with a CMTI of up to 150 kV/µs, a wide operating temperature range (-40 °C to +125 °C), and versions ready to meet immediate availability needs.
