SS54A 产品概述（Hottech 合科泰）
一、产品简介
SS54A 为 Hottech（合科泰）出品的独立式肖特基整流二极管，封装为 SMA（DO-214AC）。器件面向中小功率整流与保护场合，凭借低正向压降和快速恢复特性，在开关电源、DC-DC 转换器、续流回路与反向保护电路中具有良好性价比。
二、主要参数
- 工作结温范围：-55 ℃ ~ +125 ℃
- 正向压降：典型 600 mV @ IF=5 A
- 直流反向耐压（Vr）：40 V
- 反向电流（Ir）：500 μA @ Vr=40 V（常温）
- 平均整流电流：5 A
- 封装：SMA（DO-214AC）
- 封装形式：独立式（单颗封装）
三、产品特点
- 低正向压降：在高电流条件下仍能保持较低的压降，有助于降低整流损耗和发热。
- 低损耗与快速响应：肖特基结结构带来快速恢复性能，适合高频开关场合。
- 宽温度范围：-55 ℃ 至 +125 ℃，适应工业级工作环境。
- 紧凑封装：SMA 封装便于表面贴装（SMT），适合自动化生产与空间受限的 PCB 布局。
四、典型应用
- 开关电源（反向续流、输出整流）
- DC-DC 转换器与降压模块
- 充电设备与电源管理（反接保护）
- 汽车电子（在符合温度与振动要求时）与工业电源
五、热管理与可靠性建议
在接近额定电流 5 A 或高环境温度时，应注意功耗与结温管理：
- 在 PCB 上为二极管提供适当的铜箔散热区或散热铜毯，提高导热面积以降低结温。
- 正向压降随温度略有下降，但反向漏电流随温度大幅上升，应在高温工况下按漏电流和功耗进行裕量设计。
- 建议在长期高负载应用中进行电流热应力可靠性验证和寿命评估。
六、封装与焊接注意
SMA（DO-214AC）为常见表贴封装，推荐根据焊接工艺使用合适的回流曲线（参照无铅或有铅工艺规范），并在布板时预留足够的焊盘尺寸与散热铜箔。器件引脚与极性在 PCB 设计中需明确标识，防止装配反向。
总结：SS54A（Hottech 合科泰）为一款性能均衡的 40V/5A 肖特基二极管，适用于中小功率整流与保护场合。在实际设计中应重视热管理与反向漏电随温升的影响，以保证可靠运行。

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.
