ES2D (SMA/DO-214AC) 产品概述

一、概述

ES2D 是伯恩半导体(BORN)推出的一款快恢复/高效率整流二极管,封装为SMA(DO-214AC)。其典型电气参数为:正向压降 Vf = 950mV @ 2A,直流反向耐压 Vr = 200V,额定整流电流 2A,反向电流 Ir = 5µA @ 200V,反向恢复时间 Trr = 35ns,工作结温范围 -55℃~+150℃。该器件适用于开关电源、整流与保护等需要快速恢复与低漏电特性的场合。

二、电气特性要点

  • 正向压降:Vf ≈ 0.95V(在 2A 条件下),确保在中等电流下仍有较低的导通损耗。
  • 反向耐压:Vr = 200V,可用于较高电压等级的整流与保护电路。
  • 反向漏电:Ir = 5µA @ 200V,漏电小,有利于降低待机能耗及热耗散。
  • 反向恢复:Trr = 35ns,属于快恢复特性,能减少开关转换期间的能量损耗与电磁干扰(EMI)。

三、热与功耗考虑

在 2A 正向条件下,器件上的功耗约为 P = Vf × I ≈ 0.95V × 2A ≈ 1.9W。由于封装为SMA,散热主要依赖PCB铜箔面积与良好的布局设计,建议在高电流或连续工作场景下采用更大的散热铜箔或在附近留出热散路径,并进行适当的电流降额设计以保证长期可靠性。

四、典型应用场景

  • 开关电源(SMPS)脉冲整流与输出二极管;
  • 逆变器/变频器的快恢复整流;
  • 二极管桥、自由轮二极管(freewheeling)与续流回路;
  • 反向极性保护与过压箝位电路;
  • 需要在中高电压下保持低漏电与快速恢复的工业与消费类电子。

五、封装与机械特性

ES2D 采用 SMA (DO-214AC) 表贴封装,适合自动贴装与回流焊工艺。SMA 封装体积小、可靠性好,便于在密集PCB布局中使用。建议参考厂商数据手册中的焊盘布局与回流曲线,以确保焊接质量及良好散热。

六、选型与使用建议

  • 若系统开关频率非常高或对反向恢复损耗极为敏感,可同时比较肖特基二极管——肖特基在正向压降更低但耐压/漏电特性不同;
  • 在长期高电流应用中按环境温度做电流降额,并通过PCB散热设计降低结温;
  • 注意电路中的浪涌电流(峰值/冲击)和稳态热循环,必要时选用带有更高冲击能力的替代件或增加串联/并联保护;
  • 对于精密低漏电或超快速要求的应用,请参照完整数据手册并在实际电路中做验证测试。

七、品质与选购信息

ES2D 由伯恩半导体(BORN)生产,适合要求性价比与可靠性的量产应用。选购时请确认完整型号与批次信息,并索取最新数据手册与认证资料(如有需 RoHS/REACH 等合规性证明),以满足项目的质量与合规要求。

总结:ES2D(SMA)以其 200V 耐压、2A 额定电流、35ns 快恢复及低反向漏电的组合,适合多数中功率整流与保护场景,在保证良好热设计的前提下可提供稳定的整流性能与较高的系统效率。

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
