BAS16D-E3-08 产品概述

一、产品简介

BAS16D-E3-08(品牌:VISHAY 威世)是一款高速开关二极管,采用 SOD-123 小型表面贴装封装,适用于低功耗、高速切换场合。器件设计能在较高反向电压下保持低漏泄电流,并在小电流条件下提供稳定的整流与开关性能。其宽广的工作结温范围(-55℃ 至 +150℃)使其在工业与消费电子领域具备良好的环境适应性。

二、主要电气特性(典型/额定值)

  • 正向压降 (Vf):1.25 V @ 150 mA
  • 直流整流电流:250 mA
  • 非重复峰值浪涌电流 (Ifsm):2 A(一次性短时峰值)
  • 直流反向耐压 (Vr):75 V
  • 反向电流 (Ir):1 μA @ 75 V
  • 反向恢复时间 (Trr):约 6 ns(指示器件高速开关能力)
  • 耗散功率 (Pd):350 mW
  • 工作结温范围:-55 ℃ ~ +150 ℃

以上参数表明该器件在小信号高速开关和低功耗整流场合具有优势,尤其适合需要较高反向耐压但电流不大的应用场景。

三、特性亮点与应用场景

  • 低漏电与高反压:1 μA @ 75 V 的反向电流配合 75 V 的反向耐压,适合用于高压脉冲或反向电压较高的接口保护与整流。
  • 快速恢复:约 6 ns 的反向恢复时间,适合高速数字信号切换、开关电源的小信号路径和视频/射频前端的快速整流。
  • 小型封装:SOD-123 便于自动贴装,节约 PCB 面积,适合移动设备、消费电子和空间受限的工业控制板。
  • 浪涌容限:2 A 的非重复峰值浪涌能力允许器件在遭遇短时浪涌事件(如电源突变、电感释放)时短暂承受高电流冲击。

典型应用包括:逻辑信号整形与保护、键盘/开关去抖、隔离与反向保护、小功率整流、钳位电路、开关电源的驱动级/取样回路等。

四、封装与热管理建议

  • 封装:SOD-123,适合表面贴装工艺(SMT),利于回流焊处理和自动化生产。
  • 热管理:器件Pd 为 350 mW,属于低功耗器件。在实际布局时建议:
    • 在二极管焊盘处增加铜箔面积以帮助散热;
    • 对仍需更高散热的场合,可在焊盘下方或附近布置热铜平面并通过过孔连接散热层;
    • 避免将其置于高功率发热元件的旁侧,以降低结温上升风险。
  • 环境适应:工作结温范围宽,适合工业级温度要求,但在高结温环境下应考虑合适的电流/功耗余量。

五、使用与布局注意事项

  • 峰值与重复应力:Ifsm 为非重复峰值,仅适用于短时浪涌;在有持续高峰值脉冲的应用中应选用更高浪涌能力的型号或并联/保护电路。
  • 反向恢复与寄生:6 ns 的 Trr 说明器件适合常规高速应用,但在超高频或高速脉冲中应评估寄生电容与回路阻抗对波形的影响。
  • 极性标识:安装时注意极性,SOD-123 封装极性标记要与 PCB 严格对应。
  • 焊接工艺:遵循 VISHAY 和 SOD-123 的回流焊温度规范,避免过度加热影响器件可靠性。

六、选型参考与替代

BAS16D-E3-08 适合小电流、高反压、快速开关的场合。若需要更高整流电流或更低正向压降,可考虑同类封装中额定电流更大的器件;若追求更低 Trr 或更高峰值浪涌能力,可选用专用高速恢复型或肖特基二极管。常见对比参考型号包括 1N4148、BAS16 等小信号开关二极管(选型时请核对电压、电流、Trr 与封装要求)。

七、订购与合规信息

  • 品牌:VISHAY(威世)
  • 封装:SOD-123,适配自动贴装制造流程
  • 尾缀说明:E3 通常表示符合无铅/RoHS 要求,-08 可能指特定卷带包装规格(详情请参照厂商数据手册与订购信息)。

在实际采购与设计前,建议参考 VISHAY 官方数据手册获取完整的电气特性曲线、封装尺寸图与回流焊工艺规范,以确保在目标应用中的可靠性与性能满足要求。

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.
