ES3JC快恢复二极管产品概述

一、产品定位与核心特性

ES3JC是晶导微电子推出的独立式快恢复/高效率二极管,专为中高压、高频开关应用场景设计,兼顾低导通损耗与快速开关性能,适配多种电源及功率变换系统。其核心特性可概括为:

  • 600V直流反向耐压,覆盖中高压应用需求;
  • 35ns反向恢复时间(Trr),满足高频开关的快速关断要求;
  • 1.68V低正向压降(Vf)@3A,显著降低导通损耗;
  • 9A额定正向电流,支撑中等功率负载;
  • 宽工作结温范围(-55℃~+150℃),适应极端环境。

二、关键电气参数详解

ES3JC的电气参数经过严格设计与测试,各指标直接影响实际电路性能:

1. 正向特性

  • 正向压降(Vf):1.68V@3A:相比普通快恢复二极管(典型Vf≈2V@3A),导通损耗降低约16%,大电流场景下减少器件发热,提升系统效率与可靠性;
  • 额定正向电流(If):9A:满足中等功率负载的持续工作需求,短时间过载能力可支撑电路瞬态峰值电流(需结合降额设计)。

2. 反向特性

  • 直流反向耐压(Vr):600V:覆盖220V/380V交流输入的整流应用(含2倍线电压裕量),适配大多数中高压电源系统;
  • 反向漏电流(Ir):5μA@600V:漏电流极低,减少待机功耗,提升反向偏置下的电路稳定性,避免过热失效;
  • 反向恢复时间(Trr):35ns:属于高速快恢复等级,远低于普通整流管(Trr>100ns),在100kHz~500kHz高频开关电路中,可显著降低开关损耗与电磁干扰(EMI),提升电路响应速度。

3. 温度特性

  • 工作结温范围(Tj):-55℃~+150℃:符合工业级器件要求,可在低温(户外设备)或高温(电源内部密集布局)环境下稳定工作,无需额外散热冗余。

三、封装与可靠性设计

ES3JC采用SMC贴片封装,具备以下优势:

  • 体积紧凑:封装尺寸小(6.0mm×3.8mm×2.5mm),适合高密度PCB布局,节省电路空间;
  • 贴装便捷:适配自动化贴片机生产,提升批量制造效率;
  • 散热优化:封装底部与PCB铜箔直接接触,增强热传导能力,配合宽结温设计有效散发热量;
  • 机械可靠:引脚牢固,抗振动、抗冲击性能满足工业级标准,适合车载、工业控制等振动环境。

此外,晶导微电子通过优化芯片掺杂结构与内阻,实现低Vf与短Trr的平衡,提升器件长期可靠性与寿命。

四、典型应用场景

ES3JC凭借电气特性与封装优势,广泛应用于:

  1. 开关电源:AC-DC整流桥、DC-DC变换器续流二极管(反激/正激拓扑),降低开关损耗与EMI;
  2. 逆变系统:光伏逆变器、UPS、储能系统的逆变桥续流,适配600V级逆变需求;
  3. 电机驱动:BLDC电机、伺服电机驱动的续流二极管,支持高频PWM控制,提升电机响应速度;
  4. LED驱动:大功率LED驱动的整流与续流,低损耗提升电源效率,减少发热;
  5. 工业控制:PLC、变频器电源模块,适应宽温与振动环境。

五、品牌与市场价值

ES3JC由晶导微电子出品,该公司专注功率半导体研发,产品覆盖二极管、MOSFET等领域,具备成熟工艺与质量控制体系。其市场价值体现为:

  • 性能均衡:低Vf、短Trr、高耐压的平衡设计,满足多场景需求;
  • 成本优势:相比进口同类器件,性价比更高,适合批量应用;
  • 可靠性保障:通过工业级可靠性测试,满足工业与车载应用要求;
  • 供应稳定:规模化生产能力,保障长期供货。

总结:ES3JC是高性价比的快恢复二极管,凭借宽电压、快速开关、低损耗特性,成为中高压高频电源系统的理想选择,适配多种工业与消费电子场景。

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
