ES1B-R1-00101 快恢复二极管产品概述

一、产品基本信息

ES1B-R1-00101是台湾强茂电子(PANJIT)推出的快恢复/高效率二极管,采用独立式配置与表面贴装封装(SMA,对应国际标准DO-214AC),属于通用型中低压快恢复器件。该产品针对1A级电流承载、高频开关场景优化设计,兼顾低损耗与工业级可靠性,是小功率电源、控制电路的常用选型。

二、核心电气性能参数

器件的电气参数直接决定应用适配性,核心指标及意义如下:

  • 直流反向耐压(Vr):100V:满足绝大多数低压电源(如5V/12V/24V输出)的反向阻断需求,预留足够安全余量;
  • 整流电流(If):1A(直流):额定连续直流电流为1A,适用于1A以内的负载回路(如小型充电器、LED驱动);
  • 正向压降(Vf):950mV@1A:比普通硅整流管(典型值1.0V以上)低约5%,导通损耗减少,有助于提升电源效率;
  • 反向恢复时间(Trr):35ns:快恢复特性显著(远低于普通整流管的几百ns),适配高频开关电路(如开关电源、DC-DC变换器),可降低反向恢复损耗与电磁干扰;
  • 反向电流(Ir):150μA:反向漏电流小且稳定,长期工作时避免漏电流导致的额外功耗与性能衰减;
  • 非重复峰值浪涌电流(Ifsm):30A:能承受单次短时间(如10ms内)的脉冲浪涌,应对电源启动冲击、雷击等异常情况;
  • 工作结温范围:-55℃~+150℃:宽温范围覆盖工业级环境要求,支持车载、户外电源等极端温度场景。

三、封装与物理特性

采用SMA表面贴装封装,具有以下物理优势:

  • 体积小巧:尺寸约2.7mm(长)×1.7mm(宽)×1.1mm(高),适合高密度PCB布局,节省空间;
  • 焊接可靠:引脚采用镀锡工艺,兼容回流焊、波峰焊,焊接峰值温度≤260℃符合行业标准;
  • 环保合规:符合RoHS无铅要求,满足全球电子设备的环保法规。

四、典型应用场景

结合性能参数,该器件主要应用于:

  1. 开关电源次级整流:如手机充电器、小型LED驱动电源(1A以内),高频下快恢复特性减少损耗;
  2. DC-DC变换器续流:Buck/Boost电路中的续流二极管,承受几十kHz至几百kHz的高频开关;
  3. 低压电源适配器:如笔记本小功率适配器、智能家居设备电源,100V反向耐压满足安全要求;
  4. 工业控制模块:PLC、传感器模块的辅助电源,宽温范围适应工业现场温度波动;
  5. 小型家电电路:微波炉、电风扇的整流/续流回路,浪涌能力应对启动冲击。

五、可靠性与应用注意事项

5.1 可靠性优势

  • 宽温稳定:-55℃~+150℃结温范围,支持极端环境;
  • 抗冲击强:30A非重复浪涌电流,提升电路抗异常能力;
  • 漏电流稳定:150μA反向漏电流,长期工作可靠性高。

5.2 注意事项

  • 结温限制:工作结温不得超过150℃,需通过PCB铜箔、散热片辅助散热;
  • 浪涌限制:30A为单次非重复浪涌,不可持续承受大电流脉冲;
  • 电压限制:反向电压不得超过100V,避免击穿;
  • 焊接要求:回流焊峰值温度≤260℃,焊接时间≤10秒,防止器件损伤。

六、选型优势总结

ES1B-R1-00101的核心优势在于:快恢复适配高频、低Vf降低损耗、SMA封装小巧、宽温可靠,是1A级低压电源、高频开关电路的高性价比选型,适合对效率、空间、可靠性有要求的电子设计。

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
