SS54-SMB是固得沃克(GOODWORK)推出的独立式肖特基整流二极管,采用SMB(DO-214AA)表面贴装封装,针对中小功率低压整流场景设计,核心参数覆盖5A持续整流电流、40V直流反向耐压,且正向压降低至550mV@5A,在效率与可靠性之间实现平衡,是电子设备电源系统、控制电路等领域的常用器件。
该器件属于独立式肖特基二极管(区别于阵列式或桥式整流器),可单独作为整流单元使用,无需依赖其他封装内的并联/串联结构。肖特基二极管的本质是利用金属-半导体接触的势垒效应工作,相比普通硅整流管,具有开关速度快、正向压降低的核心优势,但反向耐压通常低于快恢复二极管,40V的直流反向耐压恰好匹配其“低压整流”的定位,避免了耐压冗余带来的成本增加。
SS54-SMB的电气参数明确了其适用边界,核心参数如下:
SS54-SMB采用SMB(DO-214AA)表面贴装封装,具有以下特点:
结合参数与封装特性,SS54-SMB的主要应用场景包括:
固得沃克(GOODWORK)作为国内专注功率半导体的品牌,SS54-SMB经过以下验证:
该器件的独立式封装避免了阵列器件的串扰问题,适合空间、成本敏感的量产场景,是替代同类器件的可靠选择。
SS54-SMB肖特基二极管以“低正向压降、5A持续电流、SMB紧凑封装”为核心竞争力,精准匹配中小功率低压整流需求,覆盖消费电子到汽车电子的多个领域。固得沃克的品牌保障与参数一致性,使其在量产可靠性与成本控制上具有优势,是电子设计中优化效率、节省空间的实用器件。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
