SS34（BLUE ROCKET）产品概述
一、产品简介
SS34 为 BLUE ROCKET 系列独立式肖特基整流二极管，封装为 SMA（DO-214AC）。该器件面向中低压大电流整流场合，具有低正向压降、较高浪涌承受能力和宽工作结温范围，适用于开关电源、DC-DC 转换、整流及反向保护等应用。
二、主要电气参数
- 正向压降 Vf：约 550 mV @ 3A（典型测试点）
- 直流整流电流 If(DC)：3A
- 直流反向耐压 Vr：40V
- 反向漏电流 Ir：约 500 μA @ 40V（室温条件下）
- 非重复峰值浪涌电流 Ifsm：80A
- 工作结温范围：-55℃ ~ +150℃
三、特点与优势
- 低正向压降：减小导通损耗，提高效率，适合高电流路径使用。
- 高浪涌能力：80A 峰值浪涌电流应付启动与短时冲击能力强。
- 宽温度范围：-55℃ 至 +150℃，适合工业级和汽车电子环境（需按应用评估整体可靠性）。
- 封装可靠：SMA 具备良好散热和 PCB 可焊性，便于自动化焊接与组装。
四、典型应用场景
- 开关电源整流与续流二极管
- DC-DC 转换器输出整流
- 反向极性保护、肖特基电源路径选择
- 电池充电/保护电路与功率路由控制
五、设计与使用注意事项
- 散热管理：尽管 Vf 低，但在连续 3A 工作下仍会产生热量，建议在布局上提供足够铜箔散热或采用散热垫。
- 反向漏电随温度上升显著增加，若在高温或高压反向工况下使用需评估漏电对系统的影响。
- 峰值浪涌仅为短时能力，长期或反复冲击需避免超过器件额定热应力。
- 焊接工艺应符合封装焊接温度规范，避免长时间高温暴露影响可靠性。
六、小结
BLUE ROCKET SS34 是一款性能均衡的 3A/40V SMA 肖特基整流二极管，适合需要低压降、高效率和中等浪涌能力的功率整流场合。在电路设计中关注散热与反向漏电特性即可获得稳定、可靠的应用表现。

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.
