SS56SMC 产品概述

一、概述

BORN(伯恩半导体)出品的 SS56SMC 是一款面向中大电流整流和保护应用的肖特基势垒二极管,封装为 SMC(DO-214AB)行业标准封装。器件主要参数包括:正向压降 Vf = 700mV @ 5A、直流反向耐压 Vr = 60V、整流电流 IO = 5A、反向电流 Ir = 500µA @60V、工作结温范围 -65℃ ~ +150℃,非重复峰值浪涌电流 Ifsm = 150A。该器件适合对开关速度和功率损耗有较高要求的场合。

二、主要性能参数(关键点)

  • 正向压降(Vf):700mV @ 5A(实际 Vf 随温度和电流变化,低温时略高)
  • 直流反向耐压(Vr):60V
  • 平均整流电流:5A(在规定散热条件下)
  • 反向电流(Ir):500µA @ 60V(高温下反向漏电会增加)
  • 非重复峰值浪涌电流(Ifsm):150A(单次半波浪涌,按规定波形)
  • 工作结温:-65℃ 至 +150℃

三、产品优势

  • 低正向压降,减少导通损耗,提升效率,适合开关电源输出整流与同步替代应用;
  • 肖特基结构,开关速度快、几乎无反向恢复损耗,利于高频电路;
  • SMC 封装具有良好功耗散热能力,便于通过 PCB 铜箔与散热处理;
  • 宽工作温度范围,适用工业级环境。

四、典型应用场景

  • 开关电源(SMPS)输出整流、续流二极管;
  • DC-DC 转换器、降压/升压模块的保护与整流;
  • 逆变器、太阳能系统的防反接与旁路保护(注意电压等级匹配);
  • 电池管理、电动车辆辅助电路、汽车电子(在符合温度与浪涌要求下);
  • 通用整流、极性保护与瞬态电流路保护。

五、封装与热管理建议

SMC(DO-214AB)封装利于散热,但设计时仍需注意:

  • PCB 上为二极管提供足够的铜面(引脚散热区)并可采用过孔通至后层散热层;
  • 尽量缩短热阻路径,保持焊盘与铜箔良好贴合,必要时并联多个器件以分摊热负荷;
  • 在高浪涌或连续大电流工况下,需进行温升分析并按厂方温度-电流曲线进行降额使用。

六、可靠性与使用注意

  • 反向漏流随结温显著上升,若系统在高温高压工况工作,应考虑漏流带来的功耗与发热;
  • Ifsm 为单次浪涌能力,避免频繁超限冲击以延长器件寿命;
  • 焊接时遵循无铅回流温度曲线与时长规范,避免长时间高温导致器件性能退化;
  • 出厂前建议参考完整 Datasheet 获取机械尺寸、热阻及电气测试条件,按应用场景选择适当的散热与保护措施。

七、选型建议

若需在 60V、约 5A 等级使用,SS56SMC 提供性价比较高的解决方案。对更高耐压或更低漏流有要求时,可考虑更高 Vr 或更低 Ir 的替代型号。采购与设计前请核对厂方完整规格书及批次测试数据。

结论:SS56SMC 是一款适合中大电流、要求低压降和快速响应的肖特基整流二极管。合理的 PCB 热设计与浪涌保护能发挥其最佳性能,建议在产品定型前进行热、电仿真与样机验证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
