SS54LC 产品概述 — JUXING(钜兴) 肖特基二极管
一、产品简介
SS54LC 是钜兴（JUXING）推出的一款独立式肖特基整流二极管，封装为 SMC。该器件以低正向压降、快速恢复特性及较高整流电流能力为主要卖点，适合各类开关电源、整流及保护电路。工作结温范围宽（-55℃ ~ +125℃），适应工业级工作环境。
二、主要参数
- 二极管类型：肖特基（Schottky）
- 封装形式：独立式 SMC
- 型号：SS54LC（品牌：JUXING/钜兴）
- 额定反向耐压 Vr：40 V
- 正向压降 Vf：约 450 mV（典型值，随电流和温度变化）
- 连续整流电流 If：5 A
- 反向电流 Ir：典型 200 μA（在额定反向电压及室温条件下，随温度升高显著增加）
- 工作结温：-55 ℃ 至 +125 ℃
三、性能特点
- 低正向压降：约 0.45 V 的典型正向压降可降低整流损耗和发热，提升效率。
- 低恢复与快速响应：肖特基结特性使其无显著反向恢复时间，适合高频开关场合。
- 高整流能力：5 A 连续整流电流，配合 SMC 封装良好散热，适用于中大功率应用。
- 宽温度范围：可在工业级温度范围内稳定工作，但高温下反向漏电流会增加，应注意热设计。
四、典型应用
- 开关电源整流与自由轮二极管
- DC-DC 转换器输出整流
- 车载电源、充电器与适配器
- 电池反向保护与电源路径选择
- 快速开关与高频能量回收场合
五、设计与使用建议
- 散热设计：SMC 封装具备良好功率散热性能，但在高持续负载下仍需在 PCB 设计中安排足够散热铜箔、散热片或热过孔以降低结温。
- 温度对性能的影响：注意高温下 Ir 增大及 Vf 轻微下降，电路设计应考虑反向漏电对待机和低功耗模式的影响。
- 电流与浪涌：推荐依据实际负载和环境温度进行电流退载（derating），避免长期满载在高环境温度下工作。
- 焊接与储存：遵循无铅或有铅焊接曲线及厂商存储、回流焊工艺要求，避免超温或潮湿引起元件性能退化。
- ESD 与极性：肖特基对静电较敏感，装配与测试时注意防静电措施；正确标注极性以免反接损坏。
六、比选与注意事项
与普通硅整流二极管相比，SS54LC 的优势在于更低的正向压降和更快的开关响应，但其反向漏电流通常较高，尤其在高温下。选型时如要求非常低的漏电流或高反向耐压，应考虑其它型号或规避方案。最终参数与性能请以钜兴官方数据手册为准，并在关键应用中进行实际热、效率与寿命验证。
如需完整电气特性曲线、封装尺寸图和焊接规范，建议向钜兴供应商索取 SS54LC 的详细数据手册。

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.
