SMD1206-075/30N 产品概述

一、产品简介

SMD1206-075/30N 是 BORN(伯恩半导体)推出的一款 1206 封装表贴自恢复保险器(聚合物 PTC / PPTC)类保护元件,专为表面贴装电路的过流、短路保护设计。器件在正常工作电流下呈现低阻抗,在过流或短路时快速升温并增大阻值,从而限制电流,故障消除后可自动恢复初始阻值,适合需要多次保护恢复的便携与消费类电子设备。

二、主要电气与环境参数

  • 耐压(Vmax):30 V(器件最大允许直流电压)
  • 最大电流(Imax):100 A(瞬态或冲击条件下可承受的极限电流)
  • 保持电流(Ihold):0.75 A(750 mA,器件在此电流下可长期保持不动作)
  • 跳闸电流(Itrip):1.5 A(器件在此电流水平下将进入高阻态以限制电流)
  • 消耗功率(Pd):600 mW(器件最大耗散功率)
  • 初始态阻值(Rmin):90 mΩ(典型/最小初始接触阻值)
  • 跳断后阻值(R1max):500 mΩ(跳闸后稳态高阻值上限)
  • 动作时间:200 ms(在标准测试条件下的典型动作响应时间)
  • 工作温度:-40 ℃ ~ +85 ℃(推荐环境温度范围)
  • 封装:1206 SMD(适配常见表贴生产工艺)
  • 品牌:BORN(伯恩半导体)

三、典型应用场景

  • USB、Type-C 接口与外围电源保护(5V/12V 等低压系统,电压不得超过 30V)
  • 手机充电器、移动电源、蓝牙音箱等便携设备的输入/输出保护
  • 主板、显示器、IoT 终端与消费电子小电流总线保护
  • 电池管理与保护电路中的过流与短路防护(配合电池保护 IC 使用)

四、选型与使用建议

  • 连续工作电流:选择 Ihold 高于设备正常最大工作电流;若设备最大持续电流接近 0.75 A,应选用留有裕量的型号或并联/替代方案。
  • 瞬时浪涌与冲击电流:Imax 为极限峰值能力,但不代表长期承受能力,建议对冲击能量和次数进行评估。
  • 动作时间:200 ms 属于中等响应速度,不适合要求亚毫秒级保护的敏感器件,可作为次级或电源侧保护元件。
  • 环境与热设计:器件热敏,应避免在高温密闭空间中使用或紧邻发热元件,必要时在 PCB 设计中留有散热间隙并进行热仿真验证。
  • 焊接工艺:遵循 1206 SMD 标准的回流焊工艺与制造商推荐的焊接资料,避免超出制造商允许的回流温度曲线以免影响性能。

五、注意事项与可靠性说明

  • 工作电压不得超过 30 V,超压可能造成器件损坏或失效。
  • 跳闸后阻值上升(最高至 500 mΩ),可能导致电路电压降增大,需评估保护后对下游电路的影响。
  • 产品为自恢复型,反复动作会影响长期特性,关键应用建议进行加速热循环与寿命评估。
  • 在实际设计中建议基于目标系统的温漂、布局和环境温度进行样机测试,确认动作点与恢复行为满足要求。

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
