ES5JBF 产品概述 — 晶导微电子

ES5JBF 是晶导微电子推出的一款独立式快恢复、高效率整流二极管,采用 SMBF 封装,专为中高压开关电源和功率整流场合设计。器件在保持低正向压降和快速反向恢复的同时,具备良好的耐压和抗冲击能力,适合要求效率和可靠性的工业及消费类电源应用。

一、主要性能亮点

  • 正向压降 (Vf):1.7V @ 5A,低压降有利于降低导通损耗。
  • 直流反向耐压 (Vr):600V,满足中高压整流与反向耐压要求。
  • 整流电流:5A(连续),适合中功率整流应用。
  • 反向电流 (Ir):10μA @ 600V,反向漏流小,降低待机和泄漏损耗。
  • 反向恢复时间 (Trr):35ns,属于快恢复特性,可减少开关损耗与开关干扰。
  • 非重复峰值浪涌电流 (Ifsm):150A,具备良好冲击承受能力。
  • 工作结温范围:-55℃ ~ +150℃(Tj),适应宽温区工作环境。
  • 封装:SMBF,便于自动贴装与热管理。

二、典型应用场景

  • 开关电源(SMPS)整流与续流二极管
  • 功率因数校正(PFC)二极管
  • 逆变器与驱动器的自由轮回整流
  • 工业电源、UPS、充电机、LED 驱动电源等高压整流场合
  • 有反向恢复时间要求的高频整流场景

三、电气与热设计要点

  • 在额定连续电流 5A 工作时,器件功耗约为 Vf×I = 1.7V×5A ≈ 8.5W,须做好散热设计。
  • SMBF 封装虽便于贴装,但高功耗场合需通过增加 PCB 铜箔面积、热铜垫和过孔将热量导出,必要时结合风冷或散热片。
  • 反向恢复时间 35ns 有助于降低开关损耗,但在高速应用仍建议评估电磁干扰与电压尖峰,必要时配合 RC 吸收或缓冲电路。
  • 非重复冲击 Ifsm=150A 能承受开机浪涌与短时冲击,但频繁浪涌会加速老化,应避免重复超过器件额定条件的冲击。

四、封装与可靠性建议

  • SMBF 封装兼顾机械强度与散热,适合自动化 SMT 贴装流程。
  • PCB 布局建议:在焊盘附近留出大面积散热铜箔并设置多条热过孔,走线尽量短且粗,减小寄生电感。
  • 储存与回流焊温度按通用 SMT 标准操作,避免长时间高温储存导致性能退化(具体请参照生产厂家的焊接与储存建议)。

五、设计注意事项与选型提示

  • 若系统对效率要求极高或工作电流远高于 5A,应考虑并联多只或选择更低 Vf 的器件,并评估电流均流问题。
  • 在高频开关电源中,快恢复特性带来的优势需与系统 EMI、驱动方式和吸收网络配合平衡。
  • 对于需要更短 Trr 或更低 Ir 的应用,可在选型时比较同系列或其他型号的参数以满足特殊需求。

ES5JBF 以其 600V 耐压、快恢复 (Trr=35ns)、低漏电 (Ir=10μA) 及 5A 连续整流能力,适合多种中高压电源整流与保护场合。选用时请结合实际散热条件与系统冲击特性,进行可靠性与效率的综合评估。如需器件数据手册或封装尺寸图,请联系晶导微电子或授权分销商获取完整技术资料。

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
