SMD0603-001/60N 产品概述

一、产品简介

SMD0603-001/60N 是 BORN(伯恩半导体)推出的一款 0603 封装自恢复熔断器(聚合物正温度系数保护器),额定耐压 60V,适用于对微弱电流进行过流保护的表贴场合。器件在过流或短路时能迅速增阻限制电流并在故障解除后自动恢复,为小型化电子产品提供可靠的重复性保护。

二、主要性能参数

  • 品牌:BORN(伯恩半导体)
  • 型号:SMD0603-001/60N(0603 封装)
  • 最大耐压 Vmax:60V
  • 最大通过电流 Imax(短时):20A
  • 保持电流 Ihold:10mA(器件在此电流下长期不动作)
  • 跳闸电流 Itrip:30mA(通常在 1s 内动作)
  • 跳闸响应时间:约 1 秒(典型条件下)
  • 功耗 Pd:500mW
  • 初始态阻值 Rmin:15Ω
  • 跳断后阻值 R1max:100Ω
  • 工作温度范围:-40℃ ~ +85℃
  • 尺寸(典型):长 1.85mm × 宽 1.05mm × 高 1.00mm

三、工作原理与典型特性

该器件为自恢复型 PTC(聚合物)熔断器。在正常工作状态下呈低阻值(典型 Rmin = 15Ω),通过保持电流 Ihold(10mA)时不会发生显著升温或动作;若电流超过设定跳闸值(Itrip≈30mA),器件内部温度上升导致电阻迅速增大(最高可达 R1max = 100Ω),从而限制故障电流并保护下游电路。故障解除并冷却后,电阻逐步回落,器件恢复初始状态,实现可重复使用的保护功能。

简单计算示例:

  • 在 Ihold = 10mA 时,电压降约 V = I·R ≈ 0.01A × 15Ω = 0.15V,功耗约 1.5mW(远低于 Pd)。
  • 在短时极限电流(Imax = 20A)时,器件可承受短脉冲能量,但不适合长期通过此类大电流,需参考厂方冲击能力曲线与 PCB 热设计。

四、封装与机械特性

  • 封装:0603(符合 SMT 工艺的超小型表贴封装),适合高密度 PCB 布局。
  • 机械强度适合自动贴装与回流焊接。具体回流温度曲线、焊接窗口请参照制造商官方资料,以避免过高回流温度影响器件特性。

五、典型应用场景

  • 移动/便携设备的输入端过流/短路保护(如耳机、蓝牙模块)
  • 低功耗传感器与 IoT 节点电源保护
  • USB/通信接口的过流限流保护(对微安至几十毫安级敏感电路)
  • 小功率 LED 灯串、监控模块、表计电子负载保护

六、设计与装配注意事项

  • 由于 Ihold 与 Itrip 之间的裕量较小(10mA vs 30mA),在系统设计时应保证正常工作电流远小于 Ihold,以避免误动作。
  • 若电路存在反复脉冲或升温环境,应评估器件在工作温度下的实际保持电流下降特性并适当留有裕量。
  • 回流焊工艺需遵循厂家推荐;若需手工焊接,避免长时间高温加热或直接烙铁接触器件。
  • 布线时避免将器件置于持续高温源附近,保证良好散热与热回流路径。

七、储存与可靠性

  • 建议干燥、常温环境存放,避免潮湿、强光或有害化学气体环境。
  • 在高温或长期振动环境中使用前建议做可靠性评估;关键应用建议索取并参考厂家的可靠性测试报告(温度循环、湿热、冲击与振动)。

八、选型与采购建议

SMD0603-001/60N 适合对毫安级电流和短路风险有严格保护需求且空间受限的电路。采购时请确认:工作环境温度、系统最大瞬态电流、长期工作电流和焊接工艺是否与器件额定值匹配。如需更高电流等级或不同响应时间的版本,可咨询 BORN(伯恩半导体)提供的完整产品系列与数据手册。

如需更详细的电气特性曲线(温度对 Ihold/Itrip 的影响、能量承受能力、脉冲曲线)与推荐布局,请提供要求,我可以协助解析厂方数据表或给出 PCB 布局建议。

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.
