ES1JB快恢复二极管产品概述

一、产品核心定位与应用场景

ES1JB是扬杰科技推出的独立式快恢复/高效率二极管,专为高频开关电源、逆变器等需要快速反向恢复特性的电路设计,核心定位是平衡效率与可靠性的中功率器件,适配中小功率电子设备的整流、续流需求。

其典型应用场景包括:

  1. 开关电源(AC-DC/DC-DC)的二次侧整流、续流回路;
  2. 太阳能/车载逆变器的逆变输出整流及续流环节;
  3. LED驱动电源的高压整流模块;
  4. UPS不间断电源的逆变/整流单元;
  5. 小型化电子设备(如手机充电器、便携式电源)的功率整流。

二、关键电气性能参数解析

ES1JB的核心参数匹配中功率高频应用需求,关键指标及实际意义如下:

  • 正向压降(Vf):1.7V@1A:额定正向电流下压降稳定,虽略高于普通硅整流管,但结合快恢复特性,高频下总损耗(正向+反向)远低于传统器件;
  • 直流反向耐压(Vr):600V:满足220VAC输入电源的整流裕量需求,避免过压击穿;
  • 整流电流(If):1A:额定连续正向电流,适配中小功率设备的功率负载;
  • 反向电流(Ir):5μA@600V:额定反向电压下漏电流极小,减少静态功耗,提升长期可靠性;
  • 反向恢复时间(Trr):35ns:快恢复核心指标,远快于普通整流管(如1N4007的μs级),可有效降低高频开关过程中的反向恢复损耗,减少EMI干扰;
  • 工作结温范围:-55℃~+150℃:宽温适应能力,满足工业级环境(如车载、户外设备)的温度波动需求。

三、封装与物理特性

ES1JB采用SMB(DO-214AA)表面贴装封装,具备以下实用优势:

  • 体积紧凑:典型尺寸约3.5mm×2.5mm×1.5mm,节省PCB空间,适配小型化设备设计;
  • 贴装便捷:符合SMT自动化生产要求,降低人工成本,提高生产效率;
  • 散热可靠:封装结构利于热量传导,配合PCB铜箔设计可满足1A电流下的散热需求;
  • 极性清晰:封装表面的阴极标识(如色环)便于焊接识别,避免极性接反导致器件损坏。

四、可靠性与环境适应性

ES1JB的可靠性设计适配工业及消费电子的长期运行需求:

  • 宽温稳定性:-55℃至+150℃的结温范围,可在极端温度(如车载冬季低温、夏季高温)下稳定工作;
  • 低漏电流:5μA的反向漏电流远低于行业标准,减少静态功耗,降低设备发热;
  • 抗过压能力:600V反向耐压留有足够裕量,可承受电源瞬态过压(如雷击、开关浪涌);
  • 环保合规:符合RoHS无铅标准,适配全球市场的环保要求。

五、选型与应用优势

对比同类产品,ES1JB具备以下选型优势:

  1. 高频效率高:35ns反向恢复时间适配100kHz以上开关频率,总损耗比普通快恢复管降低约15%;
  2. 参数均衡:1A/600V规格覆盖80%以上中小功率电源需求,无需额外降额;
  3. 供应稳定:扬杰科技作为国内功率半导体龙头,产能充足,交货周期短;
  4. 成本可控:国产替代优势明显,性能接近进口同类产品(如ST、ON快恢复管),但价格更具竞争力。

综上,ES1JB是一款适配高频中功率应用的高性价比快恢复二极管,可满足多数电子设备的整流、续流需求,兼具可靠性与成本优势。

Electronic component sourcing availability dashboard with ESD-protected samples

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
