SS84C 产品概述 — 肖特基二极管（晶导微电子）
一. 产品简介
SS84C 是晶导微电子推出的一款独立式肖特基整流二极管，封装为 SMC，面向高电流整流和开关电源应用。其典型电气参数包括：正向压降 Vf = 0.55V（在 8A 条件下）、直流整流电流 Io = 8A、直流反向耐压 Vr = 40V、反向漏电流 Ir = 1mA@40V、非重复峰值浪涌电流 Ifsm = 150A，工作结温范围为 -55℃ ～ +150℃。
二. 主要特性
- 低正向压降：Vf 约 0.55V（8A），可降低整流损耗和发热。
- 快速响应：肖特基结结构无明显反向恢复特性，适合高速开关场景。
- 高浪涌能力：Ifsm = 150A，能承受短时冲击电流。
- 宽工作温度：-55℃ 至 +150℃，适应苛刻环境。
三. 典型应用
- 开关电源整流（输出二极管、续流二极管）
- 车载电源与电机驱动（反向保护、整流）
- 太阳能逆变器及电池管理
- 电源杂散电流吸收与反向防护电路
四. 电气与热设计建议
- 功率损耗近似 P = If × Vf，满载 8A 时约为 4.4W，需合理散热设计。
- 推荐在 PCB 上采用大面积铜箔和过孔连接多层散热平面，以降低结-环境热阻。
- 对于高峰值电流场合，注意回路电感与走线宽度，减少过冲与 EMI。
五. 使用与可靠性注意
- 非重复峰值 Ifsm 为短时值，应避免重复或长时间冲击；选择熔断或限流保护以保证可靠。
- 储存与贴装时遵守防潮与静电防护规范，避免焊接应力过大导致封装损伤。
- 在高温或高反向电压下，反向漏流会增加，应在设计时留有裕量。
六. 结论
SS84C（晶导微电子，SMC 封装）以其低 Vf、高浪涌能力和宽工作温度，适合要求高整流电流与快速响应的电源类应用。合理的热管理与电路保护能显著提升器件寿命与系统稳定性。若需样品、封装资料或更多电气参数（温度特性、典型曲线），可联系晶导微电子技术支持获取完整数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
