SMD0603-020/09N 产品概述

一、产品简介

SMD0603-020/09N 为 BORN(伯恩半导体)推出的小型自恢复贴片保险器(PTC),采用0603封装(尺寸约 1.85 × 1.05 × 0.7 mm),专为便携电子与空间受限电路的过流保护设计。在正常工作时呈现极低阻值,遇到过流或短路时自动跳闸并恢复,可有效保护电源线、USB/数据接口、电池与继电器驱动等负载。

二、主要参数

  • 耐压 (Vmax):9 V
  • 最大电流 (Imax):35 A(器件承受的短时浪涌/峰值能力)
  • 保持电流 (Ihold):200 mA(长期不致跳闸的最大电流)
  • 跳闸电流 (Itrip):500 mA(典型触发过流电平)
  • 消耗功率 (Pd):500 mW(额定功耗)
  • 初始阻值 (Rmin):550 mΩ(常态低阻)
  • 跳断后阻值 (R1max):≤ 3.5 Ω(跳闸后电阻)
  • 动作时间:600 ms(典型动作响应)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 外形尺寸:长 1.85 mm × 宽 1.05 mm × 高 0.7 mm
  • 封装:0603(表贴)

三、主要特性

  • 超小0603体积,适合高密度PCB布局。
  • 正常工作阻值低,压降小,适合低压电源保护。
  • 支持较大瞬态浪涌(Imax 35A),对短时冲击电流有良好承受能力。
  • 自恢复功能,触发后无需更换,降低维护成本。
  • 宽工作温度范围,适合工业与民用环境。

四、典型应用场景

  • 手机、平板、可穿戴设备等便携设备的电源线及充电保护;
  • USB、数据接口与配件(音频、外设等)过流防护;
  • 小型电池管理与保护电路;
  • 物联网终端、传感器电源保护;
  • 工业控制中低压电源模块的局部保护。

五、选型与使用建议

  • 选型时以 Ihold 与 Itrip 为关键依据:运行电流应低于 Ihold(200 mA),而可能出现的异常峰值若超过 Itrip(500 mA)就会触发保护。
  • 对可能出现的高能量短时浪涌,应确认 Imax(35 A)是否足够承受。
  • 考虑器件 Pd(500 mW)与周围散热条件,环境温度升高会降低持续电流承受能力,应适当留有裕量并在热源附近避免并排密封。
  • 放置建议靠近被保护电源入口或器件,缩短故障点到保护器的距离以提升保护即时性。

六、安装与工艺注意事项

  • 采用标准0603表贴工艺,使用与元件尺寸匹配的贴装吸嘴与贴片机参数。
  • 推荐采用厂家或行业推荐的焊盘尺寸与锡膏量以保证焊点可靠性,避免“立碑”或偏位。
  • 遵循推荐回流焊工艺曲线,避免超过规定高温峰值与过长热浸时间以防损伤元件特性。
  • 装配与维修时避免对封装施加过大机械应力,防止内部结构损伤。

七、可靠性与测试建议

  • 量产前进行样品的 I–V 曲线测试、热稳定性测试与多次触发恢复测试,验证 Ihold/Itrip 与跳断后电阻等关键参数。
  • 在目标应用的最高工作温度与最低温度下进行功能验证,评估温漂与触发一致性。
  • 建议进行湿热、振动与焊接可靠性测试以满足长期使用需求。

八、注意事项与采购

  • 切勿在电路中超过 9 V 的持续电压,超压可能导致器件失效。
  • 跳闸后器件会升高至 ≤3.5 Ω,需等待充分冷却恢复至低阻状态;频繁重复触发可能影响寿命与恢复性能。
  • 订购与大批量使用前,请向 BORN(伯恩半导体)索取详细数据表、回流焊工艺建议及包装形式(卷带/盘装等),以确认最终应用的兼容性与质量保证。

Sourcing availability signal

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
