SMD1206-200/06N(BORN)产品概述

一、产品简介

SMD1206-200/06N 是 BORN(伯恩半导体)推出的一款 1206 封装聚合物自恢复保险丝(PTC resettable fuse)。该器件适用于低压直流保护场合,额定耐压 6V,保持电流(Ihold)2A,跳闸电流(Itrip)4A,针对短路或过流故障提供可复位的过流保护,避免一次性熔断元件更换成本与维护复杂性。

二、主要电气与机械参数

  • 耐压(Vmax):6V(适用于 5V/3.3V 等低压电路)
  • 最大电流(Imax):100A(短时突发浪涌能力,非连续工作电流)
  • 保持电流(Ihold):2A(长期不触发的最大电流)
  • 跳闸电流(Itrip):4A(导通到高阻状态的典型触发电流)
  • 消耗功率(Pd):800mW(额定条件下的功耗参考)
  • 初始态阻值(Rmin):18mΩ;跳断后阻值(R1max):85mΩ
  • 动作时间:500ms(在规定过流条件下的典型动作时间)
  • 工作温度:-40℃ ~ +85℃
  • 尺寸:3.2mm × 1.6mm(1206 封装)

三、产品特性与优势

  • 小型 SMD 封装,适合高密度 PCB 布局与自动化贴装。
  • 自恢复设计:过流后进入高阻状态限制电流,故障清除后能自动恢复导通,减少维护。
  • 低初始电阻,降低正常工作时的功率损耗与发热。
  • 较高的浪涌承受能力(Imax),能够应对短时启动或突波电流。
  • 宽温度工作范围,适合便携设备与工业级温度要求。

四、典型应用场景

  • USB、移动电源、单节锂电池保护与电源轨短路保护(5V 或更低电压系统)。
  • 便携式电子设备、蓝牙音箱、摄像头、可穿戴设备等对维修成本敏感的产品。
  • 低压控制线路、模块化电源保护以及初级过流保护方案。

五、选型与使用建议

  • 确认系统工作电压低于或等于 6V,避免超过器件最大耐压。
  • 正常工作电流应低于 Ihold(2A),如存在较大稳态电流需选用更高 Ihold 的型号。
  • 注意 Imax 为短时浪涌能力,不可作为连续工作电流依据。长期过流会导致过热或损坏。
  • 环境温度会影响 Ihold/Itrip,较高温度下保持电流会降低,应在设计裕度中考虑温升和散热条件。
  • 贴片焊接时遵循厂商推荐的回流工艺,避免过高峰值温度或长时间高温暴露。

六、可靠性与检测要点

  • 建议在样机阶段进行过流与反复触发测试,验证跳闸/恢复特性与 R1max 一致性。
  • 在最终产品中设置合适的板级保护与热管理,避免频繁触发导致寿命下降。
  • 对关键应用场景(如电池保护)可结合电路级断路方案共同使用,提升安全冗余。

总结:SMD1206-200/06N 为一款适配低压、空间受限、需可复位过流保护的理想选择。合理评估电流等级与工作环境后,可在消费电子与便携式电源设计中替代一次性保险元件,实现更高的可靠性与维护便利性。若需最终焊接规范与更详细的电流-温度曲线,请参照 BORN 官方数据手册。

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
