BAV70 产品概述(GOODWORK 固得沃克)

一、产品简介

GOODWORK(固得沃克)BAV70 为一款高可靠性的开关二极管,封装为 SOT-23,内部为一对共阴极(双二极管共阴)配置。器件针对高速开关和小信号整流场景设计,具有低反向电流、短反向恢复时间和适中的正向压降,适合在信号整形、逻辑隔离与峰值夹位等应用中使用。

二、主要电气参数

  • 二极管配置:1 对共阴极(双二极管)
  • 最大耗散功率(Pd):0.225 W
  • 允许直流正向电流(IF):200 mA(连续)
  • 典型正向压降(Vf):1.25 V @ 150 mA
  • 直流反向耐压(Vr):70 V(产品规格线)
  • 非重复峰值浪涌电流(Ifsm):500 mA
  • 反向电流(Ir):2.5 μA @ 25 V
  • 反向恢复时间(Trr):6 ns(快速恢复,适合高速开关)
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-23(表面贴装)

以上参数反映了 BAV70 在低功耗高速切换场合的平衡表现:低 Ir 有利于低漏电要求电路,6 ns 的 Trr 使其在 MHz 级别切换仍保持良好响应。

三、典型应用场景

  • 高速开关与脉冲整形电路:快速反向恢复适合开关频率较高的信号链路。
  • 射频前端和混频器(作为检波/限幅):在非严苛 RF 功率条件下可用作信号整流与限幅。
  • 逻辑电平隔离与钳位:共阴极配置便于构建二路输入共享同一参考的钳位网络。
  • TVS 前级、小信号整流与峰值保持电路:低反向漏电和中等正向压降有利于小信号处理。
  • 通用表面贴装电子设备与消费类电子的小功率整流/保护电路。

四、封装与散热建议

BAV70 采用 SOT-23 小型封装,适合高密度 PCB 布局。由于 Pd = 0.225 W,实际应用中应注意热管理:

  • 尽量将器件焊接到有散热铜箔的焊盘上,增加热扩散面积。
  • 避免长期在额定最大 IF 和环境温度下工作;建议在高温环境下进行电流降额。
  • 对于脉冲或浪涌条件,参考 Ifsm 限值并保证脉冲宽度及占空比在安全范围内。

五、选型与注意事项

  • 若电路需承受更高反向电压或更低正向压降,请参考同系列或替代型号(注意 Vr 与 Vf 的平衡)。
  • 高频或射频应用中需关注封装寄生电容、引线电感对性能的影响;SOT-23 的并联/布局会影响带宽。
  • 在有严格漏电要求的设计中,注意 Ir 随温度上升会增加,必要时留有裕量。
  • 电路设计时应考虑反向恢复(Trr)对开关损耗和电磁干扰的影响,必要时加缓冲/吸收网络。

六、小结

GOODWORK BAV70 是一款面向高速开关与小信号整流的双二极管(共阴极)器件,SOT-23 封装、短反向恢复时间(6 ns)、低反向电流与中等正向压降(1.25 V@150 mA)使其在消费电子、通信和信号处理电路中具有较强的适用性。设计时应留意功耗与热管理,依据实际工况适当降额使用以保证长期可靠性。若需替代、量产建议或更详细的封装与热阻数据,可联系 GOODWORK 或查看完整数据手册。

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.
