ES5G 二极管(BORN/伯恩半导体)产品概述

一、产品简介

ES5G 为 BORN(伯恩半导体)推出的一款通用大电流整流二极管,采用 SMC 塑料封装,适用于工业电源、家电和电机驱动等场景。器件为独立式单只二极管,极性通过封装色带标识阴极,外壳为模塑塑料,可靠性与实用性兼顾。

二、主要电气参数

  • 正向压降(Vf):1.7 V @ 5 A
  • 额定整流电流(If):5 A(直流)
  • 直流反向耐压(Vr/RRM):400 V
  • 反向电流(Ir):5 μA(典型/最大工况)
  • 反向恢复时间(Trr):35 ns
  • 非重复峰值浪涌电流(Ifsm):300 A
  • 工作结温范围:-55 ℃ ~ +150 ℃

三、关键特性与优势

  • 高耐压:400 V 额定使其可直接应用于 220 VAC 整流与中高压开关电源输入端。
  • 大电流能力:5 A 连续整流能力与 300 A 峰值浪涌能力(Ifsm)适合突发启动和浪涌场景。
  • 中等快速恢复:35 ns 的反向恢复时间在多数工业开关电源与整流应用中表现良好,减少开关损耗与电磁干扰(需配合系统设计)。
  • 低泄漏与宽温度范围:5 μA 的反向电流及 -55 ℃~+150 ℃ 的结温范围,满足恶劣环境工作要求。
  • 标准封装:SMC 塑料封装便于自动贴装与大规模制造,色带明确标识阴极极性,装配检验方便。

四、典型应用场景

  • 桥式整流器与输入整流(220 VAC 开关电源)
  • 开关电源(SMPS)输出整流或续流(二极管并联或单个使用,视电流需求)
  • 电机驱动的回驰(freewheel)整流及保护电路
  • 电池充放电回路、UPS、家用电器(微波炉、洗衣机)等需要高耐压大电流的场合

五、热管理与使用建议

  • 正向功耗在高电流下显著:在 5 A 条件下 Pd ≈ 1.7 V × 5 A = 8.5 W,需在 PCB 设计中配备足够铜面和散热通道,或采用散热片/热垫片以降低结温。
  • 由于反向恢复行为(Trr = 35 ns)会产生恢复电流峰值,建议在高 dV/dt 或高频开关场合增加 RC 吸收或合适的缓冲电路以抑制尖峰与振铃。
  • 峰值浪涌 Ifsm = 300 A 表明能承受电源瞬态浪涌,但不要以此为长期工作值,建议在浪涌保护和限流措施下使用。

六、封装与焊接注意

  • 封装:SMC 塑料封装(模塑),极性通过色带标注阴极。
  • 焊接:兼容常规回流焊工艺,遵循封装制造商提供的温度剖面与复合焊接规范。为保证长寿命与低热阻,请避免过度热应力与机械应力。
  • 存储与处理:避免潮湿环境长时间暴露,存储在干燥箱或按包装说明回潮处理(若适用)。

七、可靠性与选型提示

  • 在高温、高电流环境下,应按最坏工况计算结温并留有裕量,避免长期在极限参数下工作以延长寿命。
  • 若需要更低正向压降或更快恢复时间,可考虑选择肖特基或快恢复(Fast Recovery)系列器件;但需在耐压、泄漏和温度特性之间权衡。
  • 多并联使用时注意电流共享机制与均流电阻设计,防止单颗器件过热失效。

八、结语与采购信息

ES5G(BORN)以其 400 V 耐压、5 A 连续整流能力与 300 A 峰值浪涌能力,适合各类中高压、大电流的整流与续流应用。针对具体电路环境,建议在设计初期结合热仿真与浪涌分析确定 PCB 散热与保护方案,确保器件长期稳定运行。若需样品、批量采购或完整规格书(Datasheet),可联系 BORN(伯恩半导体)授权分销商获取详细资料与支持。

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.

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
