DSS36 产品概述
一、概述
DSS36 是富芯森美（FUXINSEMI）出品的一款小型整流二极管，SOD-123 封装，额定整流电流 3A，反向耐压 60V，适用于对体积和成本敏感的中低压电源场合。器件工作结温范围宽（-55℃～+150℃），适应工业级及高温环境下的应用需求。
二、关键电气参数及意义
- 正向压降 Vf = 850mV @ 3.0A：在大电流下仍保持较低压降，有利于降低导通损耗。
- 整流电流 Ia = 3A：适合中等功率的整流与保护场景。
- 非重复峰值浪涌电流 Ifsm = 60A：具备良好的浪涌承受能力，可应对短时电流冲击（如整流整机通电峰值）。
- 直流反向耐压 Vr = 60V / 反向电流 Ir = 100µA@60V：60V 的反向耐压覆盖常见 12V/24V 系统，100µA 的反向泄漏在高阻电路中需注意。
- 工作结温 -55℃～+150℃：适合宽温度范围使用，但长期高温应留有裕量。
三、典型应用场景
- 开关电源输出整流、二次整流；
- 电源板上局部供电与极性保护；
- 电池充放电路径、车载电子（须按车规测试验证）；
- 轻负载到中等负载的整流和浪涌保护场景。
四、封装与散热建议
SOD-123 为小型贴片封装，热阻较大。以给定 Vf 与 3A 连续电流估算，器件功耗 Pd ≈ 3A × 0.85V ≈ 2.55W，长期在该功耗下工作需要通过 PCB 进行有效散热：
- 在封装下方及引脚处铺大面积铜箔并使用多通孔过孔导热；
- 缩短导流走线、加宽铜厚以降低串联电阻与局部升温；
- 在高温或持续大电流场合考虑并联或采用更大封装的器件。
五、选型与可靠性提示
- 若系统中漏电流敏感，应评估 100µA@60V 在最高工作温度下的变化；
- 在需频繁高电流浪涌或长期 3A 连续工作时，优先验证 PCB 热设计或选用更低热阻封装；
- 最终选型与认证应参考厂方完整数据手册并进行实测确认（包括热仿真、冲击与寿命测试）。
如需参考电路建议或 PCB 布局范例，我可根据实际应用场景（输入电压、最大连续电流、允许温升）给出更具体的设计建议。

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.
