PGB1010603NRHF 产品概述

一、产品简介

PGB1010603NRHF 是 Littelfuse(美国力特)推出的一款单路双向聚合物(Polymer)ESD 抑制器,封装为 0603(1608 metric)两端 2‑Pin 结构。器件面向对信号完整性要求高且需抗静电放电的接口保护场景,典型标称反向截止电压(Vrwm)为 24V,钳位电压约 150V,结电容极低(Cj = 0.06pF),工作温度范围宽(-65℃ ~ +125℃),并满足 IEC 61000-4-2 静电放电防护要求。

二、主要特性

  • 双向(Bi‑Dir)保护,适用于可能出现双极性瞬态的信号线或电源线的防护;
  • 单通道设计,2‑Pin 0603 封装,便于在空间受限的高密度 PCB 上使用;
  • 低结电容 0.06pF,最大限度降低对高速差分/单端信号(如高速串行、视频、射频前端等)的影响;
  • 反向截止电压 Vrwm = 24V,适配 24V 级别的系统工作电压边界;
  • 钳位电压约 150V,在发生 ESD 暴击时能限制瞬态电压,保护下游器件;
  • 工作温度 -65℃ 到 +125℃,适合汽车级和工业级环境;
  • 符合 IEC 61000‑4‑2 规范的 ESD 防护特性。

三、典型应用场景

  • 高速数传接口的输入/输出保护(如摄像头接口、差分对、低电容数据线);
  • 工业控制模块、传感器接口、通信端口的抗静电保护;
  • 消费电子与便携设备在 I/O 口和外部连接器处的防护;
  • 需要小封装、高带宽且可靠性的电子系统。

四、关键电气参数(要点)

  • 类型:ESD Suppressor,聚合物材料,双向;
  • 通道数:单路(Single channel);
  • 反向截止电压 Vrwm:24V;
  • 钳位电压:150V(典型);
  • 结电容 Cj:0.06pF(极低,利于信号完整性);
  • 封装:0603(1608 Metric),2‑Pin;
  • 工作温度:-65℃ ~ +125℃;
  • 防护等级:符合 IEC 61000‑4‑2。

五、PCB 布局与安装建议

  • 器件应尽量靠近被保护的连接器或引脚放置,走线尽量短且宽,减小回路电感与串联电阻;
  • 双向器件两端直接接入被保护信号线,不要在器件与接口之间放置较长走线或大电感元件;
  • 对于共地保护,确保旁路或地平面具有低阻抗连接以便快速泄放能量;
  • 采用标准无铅回流焊工艺贴装,具体回流温度曲线与可焊性需参考 Littelfuse 官方资料和器件封装说明。

六、选型建议与注意事项

  • 若系统工作电压持续高于 Vrwm(24V),应选用更高 Vrwm 的型号以避免误触发;
  • 对于多通道差分信号,推荐为每个信号线独立配置低电容抑制器,或根据参考设计使用配对器件;
  • 在要求更低钳位电压或更高能量吸收能力时,比较同系列其他型号的钳位性能与脉冲吸收能力;
  • 进行系统级 ESD 测试时,以 IEC 61000‑4‑2 为基准验证器件在实际 PCB 上的防护效果,包含接地布局与接头机械结构的综合影响。

七、结论

PGB1010603NRHF 以其 0603 超小封装、极低结电容(0.06pF)、双向保护与 24V 工况兼容性,适合对信号完整性要求高且空间受限的接口防护应用。结合 -65℃ 至 +125℃ 的宽温特性与 IEC 61000‑4‑2 的防护要求,它是工业、汽车与消费电子中保护高速信号线抗静电的优选之一。选型时请结合系统工作电压、所需钳位水平与 PCB 接地方案进行验证,并参照 Littelfuse 的详细数据手册完成最终设计与可靠性评估。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
