SS520 产品概述
一、产品简介
SS520 是晶导微电子推出的一款独立式肖特基二极管，封装为 SMA，设计用于中高电流整流与保护场合。器件工作结温范围为 -55℃ 至 +150℃，兼顾工业级宽温特性与良好的热稳定性，适合于电源、电机驱动及汽车电子等应用。
二、主要参数
- 二极管类型：肖特基二极管（Schottky）
- 正向压降：Vf = 850 mV @ If = 5 A
- 最大整流电流：Io = 5 A（直流）
- 非重复峰值浪涌电流：Ifsm = 150 A
- 直流反向耐压：Vr = 200 V
- 反向电流：Ir = 300 μA @ Vr = 200 V
- 工作结温：-55℃ ~ +150℃
- 封装：SMA（适合自动贴装与较高功耗散热）
三、性能亮点
一、高耐压与中等漏电：200 V 的反向耐压使其可用于较高电压的开关电源与整流场景；在 200 V 反向时漏电约 300 μA，能在高压下保持较低损耗。
二、良好浪涌能力：150 A 的非重复峰值浪涌电流保证在启动或短时过载时的承受能力。
三、宽工作温度：-55℃~+150℃ 满足工业及汽车级环境需求。
四、SMA 封装：体积小、方便 PCB 布局，并可通过良好焊盘设计实现热量散发。
四、典型应用
- 开关电源输入/输出整流
- 逆变器与电机驱动的续流二极管
- 车载电子（在满足温度和漏电要求下）
- 大功率二次侧整流与保护电路
- 高频整流及快速恢复应用
五、热设计与注意事项
因正向压降在大电流下接近 0.85 V，长期 5 A 工作会产生明显功耗（P = Vf × I ≈ 4.25 W），建议：
- 在 PCB 上设计较大铜箔并使用散热槽或散热过孔，减小结壳温升；
- 注意反向漏电随温度上升显著增加，在高温条件下需预留足够余量；
- 高频开关场合注意结电容与恢复特性对EMI 的影响，必要时加入 RC 滤波或布局优化。
六、选型建议
在选用 SS520 时，应评估实际工作电压、平均与峰值电流、工作温度及散热条件。若需要更低 Vf 或更高持续电流，建议选择更大封装或并联多只器件；若要求极低漏电，可比较同规格下低漏型肖特基或复合整流方案。
SS520 在中高压、5A 级整流与保护应用中提供了平衡的电气性能与封装便利性，是多类工业与消费电子电源设计中的可靠选择。

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.
