SS34-SMB 产品概述
一、产品简介
SS34-SMB（品牌：GOODWORK 固得沃克）是一款独立式肖特基整流二极管，采用SMB（DO-214AA）封装，专为中等电流、低压降整流和保护电路设计。肖特基结特性使其具有低正向压降和快速恢复性能，适合开关电源、DC-DC转换器及整流应用。
二、主要参数
- 器件类型：肖特基二极管（独立式）
- 型号：SS34-SMB（GOODWORK）
- 额定整流电流（If）：3 A（直流）
- 正向压降（Vf）：典型 0.55 V @ 3 A（25℃）
- 直流反向耐压（Vr）：40 V
- 反向漏电流（Ir）：100 μA（典型，25℃）
- 非重复峰值浪涌电流（Ifsm）：80 A（常见测量条件为 8.3 ms 半波）
- 工作结温范围：-65 ℃ 至 +150 ℃
- 封装：SMB（DO-214AA）
三、性能特点
- 低正向压降：0.55 V @ 3 A，有效降低整流损耗与发热。
- 快速响应与低恢复时间：肖特基结特性适合高频开关场合，减少反向恢复造成的干扰与损耗。
- 良好的浪涌承受能力：Ifsm 80 A，可承受短时启动或冲击电流。
- 宽温度范围：工作结温覆盖工业级至军规边界，适应恶劣环境。
四、典型应用
- 开关电源输出整流与续流二极管（SMPS）
- DC-DC 转换器整流与自由轮二极管
- 逆向极性保护与电源反向保护电路
- 电池充放电管理、电源ORing
- 一般工业电源与通信设备的整流与保护
五、设计与使用注意事项
- 热设计：在 3 A 工况下，二极管功耗约 Pd = Vf × If ≈ 0.55 V × 3 A = 1.65 W，需通过PCB铜箔扩展与散热设计降低结温，避免长期高温工作降额。
- 漏电随温升增大：100 μA 为典型室温值，高温时漏电会显著上升，热敏感电路需考虑温漂影响。
- 浪涌测量条件：Ifsm 标注通常为 8.3 ms 半波峰值，设计中应区分重复与非重复冲击并预留防护。
- 焊接与可靠性：建议按制造商推荐的回流焊曲线和工艺进行焊接，避免超时超温对结点可靠性影响；批量生产请参考 GOODWORK 正式数据手册。
- 替代与选型：SS34 为通用型号，市场上多家厂商有等效件；在替换时注意正向压降、Vr、If、Ifsm 及封装一致性。
六、封装与订购信息
- 封装形式：SMB（DO-214AA），适合自动贴装及波峰/回流焊接。
- 标记与包装：请参考 GOODWORK 出货标签与包装说明，批量采购时建议索取物料表（MFG PN）与检验报告以确认参数一致性。
- 选购建议：若系统电压或浪涌能量超出 40 V/80 A 等级，请选用更高耐压或更大浪涌能力的型号；对更低正向压降有要求时，可比较同类低Vf肖特基或并联使用方案（并联时需注意电流均分措施）。
备注：以上参数与建议基于常规试验条件与典型器件特性，具体的热阻、回流焊曲线与测试条件请以 GOODWORK 官方数据手册为准。

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.
