上海长园维安电子线路保护有限公司(原名上海维安热电材料股份有限公司)创建于1996年,是全球领先的线路防护元器件及保护模块组件提供商。公司控股股东为香港实业家李嘉诚旗下的上市公司深圳市长园集团股份有限公司。公司主要产品包括PPTC、CPTC、PCM、Chip Fuse、TVS、SESD、Thyristor、PESD 等,应用领域涵盖通讯、可充电电池、IT设备、汽车电子、工控设备及消费类电子等产品。公司自1996年起连续被评为上海市高新技术企业,拥有独立的知识产权体系和100多项专利。公司通过ISO9001、TS16949质量体系认证和ISO14001环境体系认证,产品通过UL、TUV、CSA等安全认证。
长园维安采用先进的超洁工艺技术和优化的设计结构,相比较传统的高压VDMOS,长园维安WMOS-SJ系列产品更具有极低的特征导通电阻及栅极电荷,可以显著改善电源系统效率,降低温度。相比较传统VDMOS,500V/600V/650V/700V/800V/900V高压超级结MOSFET(SJ-MOS)系列产品更具有更好性价比,并且重点改善了传统SJ-MOS存在的浪涌及EMI性能不佳的问题。应对电源系统小型化趋势,开发了SOT-223-2L(最小化封装),TO-220 ISO(内绝缘)等先进的封装技术。
长园维安提供各类功率器件产品,包括600V/650V/700V高压VDMOS(HV-VDMOS)系列产品、500V/600V/650V/700V/800V/900V高压超级结MOSFET(SJ-MOS)系列产品、低压MOSFET(LV-MOS)系列产品、肖特基二极管(Schottky Diode)等。该类产品在充电器、适配器、LED照明及PC领域被广泛应用。
继2012年推出第一代SJ-MOS C1后,2015年,长园维安推出第二代SJ-MOS C2系列产品。C2采用优化的设计结构,品质因数FOM比较C1系列提升38%,同时提升SJ-MOS产品性价比,在系统应用中具有更优的EMI表现,尤其适用于对效率和功率密度要求较高的各类电路,如充电器、适配器、照明、PC、TV、服务器等领域。
长园维安坚持以客户为中心、以市场为导向的理念,强调高品质与领先技术竞争力,经验丰富极具开创能力的研发团队,能对市场需求做出快速响应,不断推陈出新,追求以最短研发周期使创新产品从实验室走向客户端。连续18年被评为上海市高新技术企业,拥有独立知识产权体系及100多项专利,被评为“上海市知识产权示范企业”。
