SMD0805-010/30N 产品概述

一、产品简介

SMD0805-010/30N 是伯恩半导体(BORN)推出的一款 0805 封装自恢复保险丝(PTC 可恢复保险丝),专为便携设备、小型电源模块及保护信号/电源线的过流保护设计。器件在过流时阻值迅速上升以限制电流,故障解除后自动恢复低阻状态,适合需要多次保护与自动恢复功能的场合。

二、主要参数

  • 耐压(Vmax):30 V
  • 最大电流(Imax,峰值脉冲可承受):100 A
  • 保持电流(Ihold):100 mA
  • 跳闸电流(Itrip):300 mA
  • 消耗功率(Pd):500 mW
  • 初始态阻值(Rmin):1 Ω
  • 跳断后阻值(R1max):7.5 Ω
  • 动作时间:1.5 s(在规定的过流条件下)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 尺寸:长度 2.3 mm,宽度 1.5 mm(0805 尺寸)

三、产品特点与优势

  • 小型化:0805 封装,适合高密度 PCB 布局与自动贴片生产工艺。
  • 自动恢复:过流解除后自动恢复到低阻态,避免更换元件,提高系统可维护性。
  • 快速响应:典型动作时间约 1.5 秒,可在短时间内限制过流对后级器件的冲击。
  • 高峰值承受能力:能承受较高的瞬态脉冲电流(标称 100 A 峰值),适配电源开关瞬态或浪涌场景。
  • 宽温度范围:-40 ℃ 至 +85 ℃,可用于工业级温度环境。

四、典型应用场景

  • 移动终端与便携式设备的充电保护与过流保护。
  • 电源输入与分支线路的短路/过载保护(低功率设备)。
  • 通信设备、物联网模块、传感器前端的电流保护。
  • PCB 上需要可自动恢复保护的小功率电路。

五、封装与安装建议

  • 器件为标准 0805 表贴封装,尺寸 2.3 × 1.5 mm,适用自动贴片与回流焊工艺。
  • 建议在 PCB 走线与器件周围留有适当的热隔离区,避免邻近大功率器件持续加热导致误动作。
  • 回流焊时遵循厂商推荐的温度曲线,避免超过材料极限温度,并防止多次回流造成性能退化。

六、使用与选型注意事项

  • 选型时 Ihold 应高于正常运行电流的最大值(含容差与工况波动),以避免工作时频繁跳闸。
  • 若电路存在长期较大启动电流或浪涌,应关注 Imax(峰值承受能力)与 Pd,必要时采用并联或选择更高额定型号。
  • 环境温度对跳闸电流有显著影响:高温会降低器件的保持电流,应在最高工作温度条件下验证电路可靠性。
  • 初始阻值较小(Rmin = 1 Ω),适用于信号与小功率供电路径,但对精密测量回路需评估影响。

七、可靠性与测试建议

  • 在样机阶段进行温度升高试验、过流循环试验及浪涌承受试验,验证长期使用下的动作一致性与恢复性能。
  • 对关键应用建议做环境应力筛选(ESS)与长期老化测试,评估在高温、高湿、振动条件下的稳定性。
  • 存储与运输应避免潮湿与强烈机械冲击,贴片前如吸湿需按干燥规范处理。

总结:SMD0805-010/30N 以其小尺寸、可恢复保护与较高的瞬态承受能力,适合用于低中功率电路的过流防护。合理的选型与 PCB 热设计、以及在目标工作温度下的验证是确保可靠应用的关键。

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
