安森美标准产品系列将互补集成电路与保护及信号分立器件相结合，可缩小设计尺寸、强化接口，为汽车、工业和消费类系统提供高效可靠的性能。除LDO稳压器、放大器、逻辑器件、EEPROM和隔离器件外，产品组合还涵盖齐纳二极管、ESD/浪涌保护器件、肖特基二极管及标准整流器、双极晶体管/双极晶体管-晶体管、结型场效应管、晶体管-晶体管-晶体管、 达林顿管、射频分立器件及电磁干扰滤波器。产品提供微型封装选项（最小尺寸约0.62×0.32 mm²及1.0×0.6 mm²），配备低钳位ESD阵列（含最大插入损耗保证选项），并推出针对Vf/IF优化的肖特基二极管——包括业界首创的01005封装500mA/30V型号。
工程师可组合运用这些器件实现更快速的开发与更少的元器件：BRT集成偏置功能（17种电阻组合），CCR提供无开关EMI的恒流LED驱动，低Miller效应JFET确保射频放大器稳定性，EMI滤波阵列则为单端线路提供高衰减与卓越的钳位性能。依托Treo平台，该系列提供超过170种封装的6,000余种型号，通过标准化互操作性模块化组件，简化采购流程的同时满足汽车、工厂及消费电子设备对能效、稳健性和接口保护的全面需求。
onsemi protection devices guard every interface with low‑clamping ESD andsurge coverage from ~1–70 V, offered as singles, duals, and arrays tailoredfor high‑speed, power, GPIO, and battery lines. Selected parts provideguaranteed maximum insertion loss to preserve signal integrity, withminiaturized packages down to ~1.0 × 0.6 mm² for dense automotive,industrial, and consumer designs.EMI filters with integrated ESD deliver highattenuation in the bands that matter and excellent clamping, withcommon‑mode and LC/RC options for single‑ended lines. ComplementaryZeners spanning ~1.8–200 V and ~0.2–5 W add controlled voltage limiting, allsupported by the Treo Platform to accelerate system‑level design cycles.
