SMD0805-010/60N 产品概述

一、产品简介

SMD0805-010/60N 是伯恩半导体(BORN)推出的一款0805封装可恢复保险丝(聚合物自恢复熔断器,PPTC)。该器件针对表面贴装(SMT)小功率保护应用设计,提供短路、过流保护并在故障解除后自动恢复,适合便携设备和板级保护场景。主要物性数据如下:耐压60V,保持电流100mA,跳闸电流250mA,最大可承受冲击电流10A,封装尺寸0805(2.3mm×1.5mm×1.15mm)。

二、主要技术参数

  • 品牌:BORN(伯恩半导体)
  • 型号:SMD0805-010/60N
  • 封装:0805(2.3 × 1.5 × 1.15 mm)
  • 耐压(Vmax):60 V
  • 最大电流(Imax,短时脉冲能力):10 A
  • 保持电流(Ihold):100 mA(在规定环境下不触发)
  • 跳闸电流(Itrip):250 mA(典型或测试条件下触发)
  • 消耗功率(Pd):500 mW(额定功耗)
  • 初始态阻值(Rmin):1 Ω(典型通电前阻值)
  • 跳断后阻值(R1max):7.5 Ω(触发后的最大电阻)
  • 动作时间:1.5 s(典型值,测试条件下)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、性能特点

  • 小型化表面贴装封装(0805),便于高密度PCB布局与自动化贴装。
  • 可恢复保护:在过流或短路故障解除后,器件会随温度下降恢复低阻状态,适合重复保护需求。
  • 快速动作:在超过触发电流时可在典型1.5秒内动作,提供对持续过流的有效保护。
  • 高频冲击耐受:短时冲击电流高达10A,能承受启动浪涌或偶发大电流脉冲(注意连续承受会损坏器件)。
  • 低初始阻抗:典型初始阻值1 Ω,在正常工作电流下只会产生较小的压降(例如100mA时约0.1V)。
  • 触发后限流能力:触发后电阻上升至最高约7.5 Ω,可显著限制故障电流,具体限流值取决于电源电压(例如12V时限流约1.6A)。

四、典型应用场景

  • USB、串口或低压接口的过流保护(输入保护、外设供电保护)。
  • 便携式设备与移动电源电路的板级保护。
  • 通信设备、传感器模块和IoT终端电源线路。
  • 小功率电源轨、检测电路与信号线的防短路方案。

五、选型与使用建议

  • 工作电流裕量:建议稳态工作电流留有裕量,一般将实际工作电流控制在Ihold的70%~90%以下,以避免因环境温度或长期漂移导致误触发。
  • 温度影响:Ihold和Itrip会随环境温度上升而下降;在高温环境中请采用更低的工作电流或选用额定更高的型号。
  • 冲击电流考虑:Imax为短时冲击能力,非长期承载值;若线路存在频繁大浪涌或恒定大电流,应选择额定更高的保护器件或并联方案(并联时需注意不均流问题)。
  • 电源电压关系:触发后的限流电流取决于电源电压与触发后电阻,设计时按最坏情况(最大电压)评估限流效果与元件功耗。
  • 与其他保护并用:可与熔断器、TVS二极管等组合使用,TVS负责吸收瞬变脉冲,PPTC负责持续过流保护。

六、封装与焊接注意事项

  • 本品为0805 SMD封装,支持常见回流焊工艺。建议遵循元器件制造商或JEDEC推荐的回流曲线(控制峰值温度和停留时间)以避免材料老化。
  • 焊接后避免在高温环境下长时间暴露,以保证恢复性能和寿命。
  • 装配时避免对器件施加过大的机械应力或剪切力,焊盘设计应考虑热均衡以防局部过热影响I-V特性。

七、可靠性与储存

  • 储存环境建议干燥、无腐蚀性气体、避免阳光直射,温度与湿度按常规电子元件要求保存。
  • 长期使用中PPTC的触发特性可能随循环次数和环境条件发生漂移,关键产品应进行寿命验证与场景加速老化测试。
  • 在设计验证阶段,应做实际工况下的温升、触发时间和恢复时间测试,确保满足整机保护要求。

八、常见问题与排查

  • 若出现误触发:检查工作电流是否接近或超过Ihold、环境温度是否偏高、周围热源是否影响器件。
  • 若触发后不能恢复:可能器件受到了过度能量冲击或高温损伤,建议更换并检查故障原因。
  • 若压降过大:确认器件初始阻值和工作电流,必要时选择低阻型号或并联解决(并联需均流设计)。

SMD0805-010/60N 以其小体积与可恢复保护特性,适合对空间敏感且需重复过流保护的低功率应用。在实际使用中注意温度、工作电流裕量与浪涌特性即可获得可靠的过流保护效果。若需更详细的回流曲线、典型I–V曲线或可靠性数据,请联系伯恩半导体获取完整器件数据手册。

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.
