Renesas has announced End of Life (EOL) for its Lateral MOSFET range, which includes the popular 2SK1058. Several parts have already passed Last Time Order (LTO) and Last Time Buy (LTB) status, creating immediate challenges for manufacturers supporting existing designs or developing next generation products.
For engineers and purchasing teams seeking a dependable Renesas MOSFET replacement, Profusion offers a proven, production ready alternative: Exicon Lateral MOSFETs.
The Proven Lateral MOSFET Solution for Audio and Power Applications
With decades of experience supplying the audio industry, Exicon Lateral MOSFETs provide a secure migration path for manufacturers currently relying on Renesas equivalents, allowing designers to maintain or even improve audio performance and reliability without costly redesign.
Key benefits of adopting Exicon MOSFETs:
Long Term Availability
Exicon will continue to manufacture and support MOSFETs for the foreseeable future.
Excellent Linearity
Ideal for audio applications where signal purity matters.
Easy Paralleling for High-power Designs
Build scalable designs without added complexity.
High Quality Audio Reproduction
Trusted by leading audio brands for the most demanding applications.
Simpler, More Robust Designs
Stable lateral MOSFET characteristics mean no driver transistor required and no thermal runaway, removing the need for complex protection circuitry.
Excellent Linearity
This equates to lower distortion ideal for audio and precision amplification applications where signal purity matters.
Higher Power Versions Available
Including the 250W ECW20N20-W6 and ECW20P20-W6 for more compact designs.
Trusted by Leading Audio Manufacturers Worldwide
Exicon Lateral MOSFETs have been a popular choice for over 30 years, widely used by leading brands in high power, high quality audio and power applications, including:
- Professional and consumer power amplifiers
- Active speaker PA systems
- High end and boutique audio equipment
- Ultrasonic systems such as sonar and wire bonders
- Low field, low MHz MRI imaging systems
A Straightforward Migration Path from Renesas Obsolescence
If your designs currently specify Renesas MOSFETs, specifically the 2SJ352, 2SJ162, 2SK2221 or 2SK1058, Exicon offers proven, pin-compatible alternatives.
Profusion holds stock and provides technical guidance to support a smooth transition from Renesas MOSFETs to modern Exicon replacements.
