BAV70 开关二极管 — 产品概述
一、产品简介
BAV70（品牌：BORN/伯恩半导体）是一款高速开关二极管，采用SOT-23小封装，内部为一对共阴极（二个二极管的阴极引脚共用）。该器件针对高速开关和信号整形场合优化，具有较低的反向恢复时间和适合中小电流整流的电气性能，适用于便携式设备和数字电路中的快速切换及保护用途。
二、主要特性
- 两结共阴极（1对共阴极），方便在双路信号或整流电路中并联使用或作为钳位结构。
- 正向压降 Vf = 1.25V（在 If = 150mA 条件下）。
- 最大直流反向耐压 Vr = 70V，反向漏电流 Ir = 2.5μA @ 70V。
- 额定整流电流 If(DC) = 200mA，非重复峰值浪涌 Ifsm = 500mA。
- 反向恢复时间 Trr ≈ 6ns，适合高速开关场合。
- 耗散功率 Pd = 225mW（封装与散热条件影响器件允许功耗）。
三、电气参数（概览）
- 正向压降（Vf）：1.25V @ 150mA
- 直流反向耐压（Vr）：70V
- 反向电流（Ir）：2.5μA @ 70V
- 整流电流（If）：200mA（连续）
- 反向恢复时间（Trr）：6ns（典型值）
- 非重复峰值浪涌电流（Ifsm）：500mA
- 耗散功率（Pd）：225mW
四、封装与机械信息
- 封装：SOT-23（小体积、表面贴装）
- 引脚形式：共阴结构，便于双路对称布板和快速切换电路设计。
（具体引脚排列请参照厂商数据手册以确保焊盘设计和封装尺寸无误。）
五、典型应用
- 数字电路中的高速开关和整形：门电路、脉冲整形、钳位电路。
- 信号检测与整流：小功率整流、取样电路。
- 保护电路：反向保护、瞬态电压钳位（配合限流元件使用）。
- 便携式与消费电子：由于SOT-23小尺寸，适合手机、便携终端和可穿戴设备中的信号通道使用。
六、设计与使用注意事项
- 正向压降在150mA时约1.25V，若设计中长期大电流通流，应考虑功耗和热升高对可靠性的影响。
- Pd 为225mW，SOT-23 封装散热能力有限，建议在高占空比或高环境温度下采取降额使用或加大PCB散热铜箔。
- 反向漏流在高电压下会增加，若电路对漏电敏感，请留足裕量或选用漏电更低的型号。
- 反向恢复时间短，但在极高频率或极端条件下仍需验证是否满足系统要求。
七、总结
BAV70（BORN）为一款性能均衡的双二极管开关器件，适合中等电流下的高速开关与信号处理应用。其70V耐压、6ns恢复时间和SOT-23小封装使其在许多消费电子与工业控制的低功耗、高密度电路中具备良好的实用性。选型时请参照完整数据手册以确认环境、封装和热管理方案，确保设计长期可靠运行。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
