BAV23C 产品概述

一、产品简介

BAV23C 为扬杰(YANGJIE)出品的双二极管(1对共阴极)高速整流/开关器件,采用 SOT-23 小型封装,面向高电压、小体积、低功耗的开关与整流应用。器件工作结温范围宽,-55℃~+150℃,适用于工业级与民用高可靠性电子系统。

二、主要特性

  • 双二极管共阴极结构(1对共阴极),便于构成电平隔离、双向保护与整流网络。
  • 直流整流电流:200 mA,满足小功率整流与电平转换需求。
  • 正向压降:Vf = 1.25 V @ 200 mA,便于估算功耗与热耗散。
  • 非重复峰值浪涌电流 Ifsm = 4 A,用于吸收短时浪涌能量(非重复、峰值)。
  • 反向耐压:Vr = 250 V,适合高压开关与高压保护场景。
  • 反向恢复时间 Trr = 50 ns,高速开关响应,适合中高频率开关应用。
  • 极低反向电流 Ir = 100 nA,利于高阻态电路与微弱信号场景的漏电控制。
  • 耗散功率 Pd = 350 mW,需在 PCB 布局与散热设计中注意功率限额。

三、电性能指标(关键参数)

  • 正向电流(整流):IF = 200 mA(连续)
  • 正向压降:Vf = 1.25 V @ IF = 200 mA
  • 反向耐压:VR = 250 V(最大)
  • 反向电流:IR = 100 nA(典型/最大,随温度上升而增加)
  • 反向恢复时间:Trr = 50 ns(高速开关能力)
  • 非重复峰值浪涌电流:Ifsm = 4 A(短时脉冲)

这些指标决定了器件在高压、快速切换及低漏电场景下的适用性,同时也要求在设计时注意电流、电压及温升的边界条件。

四、封装与热管理

  • 封装:SOT-23(小型三引脚封装,共阴极两引脚为阳极/阴极组合)
  • 耗散功率 Pd = 350 mW,封装热阻较大,建议在 PCB 上增加铜箔面积或与散热平面相连,以降低结温。
  • 推荐设计:在 SOT-23 下方和引脚附近扩展铜箔、引出热过孔(via)到散热层,并在布局中避免高密度热源集中在此器件周围。
  • 工作温度范围:-55℃~+150℃,在高温环境下需进行功率降额(derating)。

五、典型应用

  • 高压信号保护与钳位(250 V 反向耐压适合线路保护)
  • 高速开关与小功率整流(Trr = 50 ns,IF = 200 mA)
  • 电平转换、逻辑隔离、混合信号路径保护
  • EMI 抑制与输入端反向保护(结合限流元件使用)
  • 便携与消费类电子中高压小电流路段的整流/保护元件

六、使用注意事项与可靠性

  • 注意功率和结温:Pd = 350 mW 为器件耗散上限,实际设计应考虑降额以保证长期可靠性,特别在高环境温度下。
  • 浪涌与瞬态:Ifsm = 4 A 为非重复峰值,禁止在循环或重复浪涌条件下依赖该参数。
  • 反向电流随温度显著上升,高温下 IR 可能超出设计容限,应对敏感电路作温度评估。
  • 焊接与工艺:SOT-23 常用回流焊工艺,遵循制造商推荐的温度曲线与湿敏等级(MSL)。
  • PCB 布局:缩短关键回路走线,避免在高速切换路径上产生寄生电感,必要时加 RC 缓冲或抑制元件。

七、采购与替代建议

  • 品牌:YANGJIE(扬杰),适合对性价比与国产供应链有需求的项目。
  • 订购信息请确认完整型号 BAV23C 与封装 SOT-23、包装形式(卷带或散装)。
  • 可考虑的替代型号需匹配:共阴极双二极管、Vr ≥ 250 V、IF ≥ 200 mA、Trr ≈ 50 ns、SOT-23 封装,以保证在电气与封装层面的可互换性。

总结:BAV23C(扬杰)是一款面向高压、高速切换与低漏电场景的小型双二极管器件,适用于多种保护与整流任务。设计时须关注功率耗散与结温管理,以确保长期稳定可靠。

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
