BAS40TW 产品概述

一、产品简介

BAS40TW(创基 CBI)是一款面向高密度表面贴装电路的高速开关二极管阵列器件。器件在微小的 SOT-363 封装中集成了三只独立的二极管,提供低正向压降与快速开关特性,适合对体积与性能均有较高要求的便携式及消费类电子产品中做信号整流、整流保护或高速开关应用。

二、主要电气参数

  • 二极管配置:3 个独立式(单封装内三只独立二极管)
  • 正向压降(Vf):1.0 V @ IF = 40 mA
  • 直流反向耐压(Vr):40 V
  • 整流电流(最大):200 mA(单只)
  • 反向电流(Ir):200 nA @ VR = 30 V
  • 工作结温范围:-65 ℃ ~ +125 ℃
  • 特性:低正向压降、快速开关

以上参数为典型/额定值,设计时应参考器件的详细数据表并考虑温度、浪涌等工况对参数的影响。

三、封装与机械特性

  • 封装:SOT-363(超小型六引脚封装),适合高密度贴片组装
  • 优势:封装体积小、占板面积低,利于便携设备、多通道设计以及节省 PCB 空间。
  • 可获得性:适合自动化贴装工艺(回流焊),常见于带卷供货,便于大批量生产。

四、典型应用场景

  • 高频信号整流与开关电路:利用快速开关特性用于高速脉冲、开关电源的辅助回路。
  • 信号路由/防反接保护:在多通道输入或保护路径中作为低压降的防反接或隔离元件。
  • 移动与消费电子:耳机接口、便携充电器、蓝牙设备等体积敏感设备的整流与保护。
  • 电平移位与夹位电路:在高速数字或模拟前端用于夹位、钳位与电平控制。

五、设计与使用建议

  • 热性能与电流降额:尽管单只整流电流可达 200 mA,长期高电流或密集并联时需考虑封装散热与 PCB 铜箔面积,避免结温过高。
  • 反向泄漏注意:反向电流为 200 nA @ 30 V,适合大多数通用用途;但在超高阻抗或精密测量电路中需评估泄漏对电路的影响。
  • 布局建议:将二极管尽量靠近开关结点或保护对象放置,缩短走线,降低寄生电感与电阻带来的开关损耗。
  • 焊接与回流:遵循常规无铅回流曲线与 IPC 标准进行焊接,避免超过器件允许的峰值回流温度和时间。
  • 并联与保护:若需更大电流,可考虑并联多只二极管,但要注意电流分担与热均衡;必要时在电路中增加限流或热保护措施。

六、可靠性与环境适配

  • 工作温度范围宽(-65 ℃ ~ +125 ℃),适用于工业级与商用温度环境。
  • 典型应用中器件表现稳定,但在高湿、腐蚀或强振动环境下应结合封装及 PCB 保护(如涂覆、密封)以提升可靠性。
  • 若项目有特殊认证(如 AEC-Q 或严格汽车级要求),请向供应商确认器件具体认证状态。

七、小结

BAS40TW(创基)以 SOT-363 小体积封装集成三只独立高速二极管,具备低正向压降(1 V @ 40 mA)、40 V 反向耐压与微小反向漏电流等优点,适合高密度 PCB 的快速开关、整流与保护应用。在设计中应关注散热、反向泄漏与贴装工艺,合理布局可发挥其在便携与消费类电子中的成本与空间优势。若需进一步的电气特性曲线、封装尺寸图或可靠性数据,建议向创基(CBI)索取完整版技术手册。

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.

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
