B340A-13 产品概述

一、产品简介

B340A-13 为 GOODWORK(固得沃克)出品的独立式肖特基整流二极管,封装为 SMA (DO-214AC),面向需要低正向压降与高速整流的电源和保护电路。此型号在直流整流电流 3A 的工况下,典型正向压降仅 0.50V,适合降额设计或要求高效率的小功率开关电源与续流路径。

二、主要参数

  • 二极管类型:肖特基二极管(独立式)
  • 正向压降 Vf:0.50V @ IF = 3A(典型值)
  • 直流反向耐压 Vr:40V
  • 额定整流电流 IF(AV):3.0A(基于良好散热条件)
  • 反向漏电流 Ir:200 µA(常见测量条件 Vr=40V,Ta=25°C)
  • 非重复峰值冲击电流 Ifsm:100A(8.3ms 半正弦波脉冲)
  • 工作结温范围:-65°C ~ +150°C
  • 封装:SMA (DO-214AC)
  • 品牌:GOODWORK(固得沃克)

三、性能特点

  • 低正向压降:0.5V@3A 的典型 Vf 有助于降低整流功耗与发热,适合需要提高效率的应用。
  • 快速开通特性:肖特基结构无恢复时间,适合高频开关电源和快速脉冲整流。
  • 良好冲击承受力:100A 的峰值浪涌能力能承受短时启动或故障浪涌电流。
  • 宽温度范围:-65°C 至 +150°C 的结温范围适应工业级环境。

四、典型应用

  • 开关电源输出整流(SMPS)与同步整流替代方案
  • 电池充电与保护电路的防回流/续流二极管
  • 车载电子(需注意汽车级认证要求)
  • 逆变器及太阳能微型逆变系统的小功率整流
  • 功率管理、稳压模块中的低压差整流

五、封装与热管理建议

SMA 封装体积小,便于自动贴装与波峰/回流焊接,但散热依赖 PCB 版图与铜箔面积。建议:

  • 在二极管焊盘下方和周围增加散热铜箔与过孔,以降低结到环境的热阻。
  • 对于连续 3A 工作,应按实际 PCB 温升和环境温度评估结温,必要时扩大散热面积或采用散热片。
  • 焊接工艺应遵循 GOODWORK 的回流温度曲线,避免超温和长时间加热导致器件应力。

六、可靠性与使用注意事项

  • 反向漏电流随温度显著上升,高温工况下 Ir 可能大幅增大,设计时需留有裕量。
  • 反向耐压为 40V,避免在高于额定 Vr 的场合使用或在突发过压时采取限流保护。
  • 长时间承受接近额定 IF 的电流会导致器件发热,需验证在目标使用环境下的寿命和温升。
  • 峰值浪涌能力为短时指标,不应将其作为连续工作依据。

七、选型与替代

B340A-13 适用于要求低 Vf、3A 连续整流和 40V 耐压的场景。若需更高耐压或更低漏电,可考虑其它肖特基或快速恢复二极管;若需更高电流等级,则选择更大封装(如 DO-214AA/DO-214AB)或并联使用并做好热均流设计。订购时请确认 GOODWORK 的完整型号、批次与质量认证,以确保可靠性与可追溯性。

如需封装尺寸图、热阻参数或典型电气特性曲线(Vf‑If、Ir‑Vr‑T),可基于具体应用索要 GOODWORK 的详细 datasheet,以便进行精确的热设计与电气仿真。

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
