SMD2920-150/60N 产品概述

SMD2920-150/60N 是 BORN(伯恩半导体)推出的一款表面贴装型保险器,面向需在有限空间内实现过流保护的电子设备。器件基于 SMD 2920 封装设计,兼顾体积与热性能,适用于多种消费及工业电子应用的短时过流保护与自恢复保护场景。

一、主要电气与热参数

  • 耐压(Vmax):60 V
  • 最大电流(Imax):40 A(极限峰值能力)
  • 保持电流(Ihold):1.5 A(长期允许通过而不触发)
  • 跳闸电流(Itrip):3 A(在标准条件下开始动作)
  • 动作时间:2 s(从触发条件到进入高阻态的典型时间)
  • 功耗(Pd):1.5 W(稳态功耗参考)
  • 初始态阻值(Rmin):35 mΩ(未动作时低阻特性)
  • 跳断后阻值(R1max):230 mΩ(动作后限制电流的高阻特性)
  • 工作温度:-40 ℃ ~ +85 ℃

二、功能特性与行为说明

该型号在正常工作时保持低阻抗,最大限度减少功率损耗与电压降;当电流超过 Itrip 并在动作时间内持续,器件进入高阻态以限制故障电流。随后在故障解除并冷却后可恢复到低阻态,用于可复位过流保护(自恢复)场合。Rmin 与 R1max 的指标可用于计算动作前后电压降和热耗散。

三、典型应用场景

  • 移动设备与充电器的输入/输出过流保护
  • 工业控制模块、传感器电源保护
  • 汽车电子的低压子系统(符合工作温度与电压要求)
  • 通信设备、电源管理模块与USB/外围接口保护

四、选型与设计注意事项

  • 确认系统工作电流在 Ihold 之下,瞬时冲击电流不会持续超过 Itrip 的 2 s 动作窗口;若有更长时间的过流需求,应选用额定更高的型号或复合保护方案。
  • 考虑 Pd 及封装散热,PCB 布线与铜箔面积应足以带走热量,避免因散热不良导致误动作或寿命下降。
  • 在40 A 的 Imax 情形下为瞬态峰值能力,连续工作不能依赖此值;以 Ihold/Itrip 为长期设计依据。
  • 跳断后阻值 R1max 用于估算故障时电压降与残留功耗,必要时在电路中设置指示或断路策略以避免长期低效耗散。

五、封装与可靠性

2920 SMD 封装适合自动贴装与回流焊工艺;出厂前应遵循厂商的焊接温度曲线与回流限制,避免超过规定的温度对材料性能造成影响。长期工作在高温或频繁动作场景会影响器件寿命,应在设计中留有裕量并考虑定期检测或替换策略。

六、使用与储存建议

  • 建议在干燥环境下储存,避免潮气和有害化学气体;贴片存放应遵循抗潮包装和保质期要求。
  • 贴装时采用标准回流工艺,避免二次加热与机械应力集中;检验焊点可靠性以保障散热与电气接触。
  • 在系统级调试阶段,结合实际工况对 Itrip、动作时间与热回路进行验证,确保在异常情况下能达到预期保护效果。

SMD2920-150/60N 以其紧凑封装、明确的保持/跳闸特性及宽工作温度范围,是需要空间受限且要求可复位过流保护应用的可靠选择。选择与布局时,请结合系统实际电流波形与热条件做最终确认。

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
