SMD0603-075/06N 产品概述

一、产品简介

SMD0603-075/06N 为 BORN(伯恩半导体)出品的微型表面贴装自恢复保险元件(PPTC),封装尺寸为 0603(1.85 × 1.05 × 1.15 mm)。该器件用于低压直流电路的过流保护,耐压 6V,具有快速动作和可复位的特点,适合空间受限的移动设备与消费电子产品。

二、主要特性

  • 耐压(Vmax):6 V,适用于常见的 5V/3.3V 等低压系统保护。
  • 最大瞬时承受电流(Imax):35 A(短时浪涌能力,用于应对瞬态冲击)。
  • 保持电流(Ihold):750 mA(在该电流下长期保持低阻态)。
  • 跳闸电流(Itrip):1.4 A(典型触发点,超过该电流将进入高阻限流态)。
  • 功耗(Pd):500 mW(稳态允许功耗,设计时需考虑功耗与温升)。
  • 初始电阻(Rmin):60 mΩ(低压降,适合电源线保护)。
  • 跳断后电阻(R1max):450 mΩ(限流后的高阻态,保护下游电路)。
  • 动作时间:100 ms(对短路和过载有较快反应)。
  • 工作温度:-40 ℃ 至 +85 ℃。
  • 封装:0603,体积小、适合高密度 PCB 布局。

三、典型应用场景

  • USB、OTG 接口、电源口过流与短路保护。
  • 移动设备、便携式仪器和物联网终端的电源线保护。
  • LED 驱动和背光模块的输入保护。
  • DC-DC 模块和电源管理芯片的前端保护。
  • PCB 上多路电源分配的局部保护元件。

四、设计与选型建议

  • 选型原则:保持电流(Ihold)应略高于正常工作电流以避免误触发,推荐留 20%~50% 的裕量;跳闸电流(Itrip)决定保护灵敏度。
  • 温度影响:环境温度升高会降低器件的保持电流和触发特性,设计时按最高工作温度下的实际电流考虑。
  • 电压与功耗:在接近 Pd(500 mW)工作点时,器件会显著升温,应保证足够的散热空间并评估电阻引起的压降。
  • 浪涌能力:Imax=35A 表明可承受短时冲击,但不作为长期过流值使用;对有频繁冲击的场合需评估寿命影响。

五、布局与焊接要点

  • 尺寸微小,建议严格按制造商的封装图设计焊盘并留足焊接面积以保证可靠焊接。
  • 推荐采用无铅回流焊工艺,遵循元件对温度敏感性及 PCB 组装规范;避免多次高温回流以防性能漂移。
  • 焊接后避免在元件上施加机械应力(弯曲或挤压),装配与测试过程中注意防止过大的插拔力直接作用于 0603 元件。

六、可靠性与安全注意

  • 长期在高温或高负载近 Pd 条件下工作,会加速老化并可能导致保持/跳闸特性变化,建议做加速寿命评估。
  • 发生跳闸后器件会冷却并自动复位,若频繁跳闸表明故障未清,应排查下游短路或设计缺陷。
  • 存储与搬运避免受潮、挤压,贴片前按厂商建议回流前的烘烤和防潮措施处理。

七、订购信息与替代

  • 品名:SMD0603-075/06N
  • 品牌:BORN(伯恩半导体)
  • 封装:0603(SMD)
  • 订购时请确认批次、打样与大货一致,并索取完整数据手册与封装图。
  • 可替代型号应匹配 Ihold/Itrip、Vmax、Pd 与封装尺寸,并注意 Rmin 与 R1max 对系统压降与保护效果的影响。

以上为 SMD0603-075/06N 的产品概述与工程应用要点,建议在最终设计前参考伯恩半导体正式数据手册,并进行样机验证以确保系统可靠性。

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
