ES1B_R1_00001 快恢复/高效率二极管产品概述

一、产品定位与核心特性

ES1B_R1_00001是PANJIT(强茂)推出的独立式快恢复/高效率二极管,针对中低压(100V以内)、中小电流(1A级)且需快速开关响应的场景设计。核心特性聚焦「低损耗+快速开关」平衡:正向压降低至950mV(1A负载下),反向恢复时间仅35ns,同时具备100V反向耐压、1A持续整流电流及30A非重复浪涌能力,适配高密度贴片设计需求。

二、关键电气参数详解

1. 正向特性:低损耗设计

额定直流整流电流为1A,在1A负载下正向压降(Vf)仅950mV——远低于普通硅整流二极管(典型1.2V以上),可显著降低整流电路导通损耗,减少电源模块发热,提升整体效率(尤其适合对功耗敏感的便携设备或小功率电源)。

2. 反向特性:高耐压+低漏电流

直流反向耐压(Vr)达100V,满足多数中低压电源的反向阻断需求;在100V反向电压下,反向漏电流(Ir)仅1μA,漏电流极小,长期工作可靠性高,避免因漏电流导致的额外功耗或器件老化。

3. 开关特性:快速响应适配高频

反向恢复时间(Trr)为35ns,属于快恢复二极管范畴(普通整流管Trr通常>100ns),可有效降低开关过程中的能量损耗,适配开关频率较高的应用(如高频开关电源、逆变器等)。

4. 环境与浪涌能力:宽温+抗冲击

工作结温范围覆盖-55℃~+150℃,可适应工业级、汽车级(若需)等宽温度场景;非重复峰值浪涌电流(Ifsm)达30A,能承受电路中的瞬态过流冲击(如电源上电瞬间、负载突变),提升系统抗干扰能力。

三、封装与可靠性说明

该器件采用SMA(DO-214AC)贴片封装,体积小巧(典型尺寸:长3.8mm×宽2.0mm×高1.0mm),适合高密度PCB布局,可降低产品尺寸与重量。封装工艺采用塑封结构,具备良好的抗潮湿、抗机械应力能力,配合宽结温范围,确保在恶劣环境下长期稳定工作(如工业现场的高低温变化、家电的日常振动)。

四、典型应用场景

ES1B_R1_00001的参数特性使其适配以下场景:

  1. 开关电源:AC-DC适配器、DC-DC转换器的整流桥或续流二极管,低Vf减少导通损耗,短Trr适配高频开关;
  2. LED驱动电源:小功率LED灯串的整流/续流,低损耗提升驱动效率,降低灯板发热;
  3. 逆变器与UPS:小型逆变器的高频整流回路,快速开关响应避免能量浪费;
  4. 家电与消费电子:微波炉、电磁炉的电源整流,抗浪涌能力满足家电瞬态冲击;
  5. 工业控制电源:PLC、传感器模块的辅助电源,宽结温适应工业现场温度变化。

五、选型优势总结

对比同参数段的普通整流二极管(如1N4001):

  • 反向恢复时间缩短60%以上,更适合高频应用;
  • 正向压降降低20%,导通损耗显著减少;
  • 浪涌能力提升20%(1N4001典型Ifsm为25A),抗冲击性更强;
  • 宽结温范围(-55150℃)优于普通整流管的-40125℃,环境适应性更广。

此外,该器件符合RoHS环保标准,可满足绿色产品设计需求,是中低压中小功率电源、高频电路的高性价比选型。

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
