ES1DB 快恢复二极管产品概述

一、产品定位与核心特性

ES1DB是扬杰科技(YANGJIE)推出的快恢复/高效率独立式二极管,专为中低压高频整流、开关电源等场景优化设计。其核心特性聚焦“高效、快速、可靠”:采用优化硅材料工艺平衡低正向压降与快反向恢复;宽结温范围覆盖工业级需求;SMB表面贴装封装适配自动化生产,是小功率电子设备替代普通整流管的高性价比选择。

二、关键电气参数详解

ES1DB的参数针对实际场景做了针对性设计,核心参数及实际意义如下:

  • 正向压降(Vf):950mV@1A:1A连续电流下压降仅0.95V,比传统硅管(如1N4001约1.1V@1A)低13%,可显著降低整流损耗、减少模块发热,尤其适合LED驱动、开关电源等对效率敏感的场景。
  • 直流反向耐压(Vr):200V:额定耐压200V,满足12V/24V系统二次整流等中低压场景需求,无需过度降额即可稳定工作。
  • 整流电流(If):1A:连续工作电流额定1A,非重复峰值电流可达30A(需结合 datasheet 确认),可应对短时间脉冲负载。
  • 反向电流(Ir):5uA@200V:200V反向电压下漏电流仅5μA,漏损耗极低,进一步提升整体效率。
  • 反向恢复时间(Trr):35ns:远优于普通整流管(如1N4001约几十μs),可减少开关尖峰与电磁干扰(EMI),适配100kHz以下高频开关电路。
  • 工作结温范围:-55℃~+150℃:覆盖工业级温度,可在户外设备、汽车辅助电路等极端环境稳定运行。

三、机械封装与可靠性

ES1DB采用SMB封装(DO-214AA),表面贴装设计具备以下优势:

  • 体积小巧:尺寸约2.7mm×3.5mm×1.9mm,节省PCB空间,适配便携充电器、LED球泡灯等小型化设备。
  • 贴装便捷:符合SMT自动化生产线要求,降低生产制造成本。
  • 可靠性强:耐高温塑料封装可承受260℃回流焊(符合JEDEC标准);引脚与封装结合牢固,抗振动、冲击性能良好,适配工业控制场景。

四、典型应用场景

ES1DB凭借特性广泛应用于:

  1. 开关电源二次整流:手机充电器、笔记本电源低压侧整流,快恢复减少开关损耗,低Vf提升转换效率。
  2. LED驱动电源:低Vf减少模块发热,避免影响LED寿命;快恢复适配高频PWM调光。
  3. 小功率逆变电路:小型太阳能逆变、应急电源逆变,快反向恢复降低开关尖峰与EMI干扰。
  4. 电池充电电路:手机、充电宝充电整流环节,低损耗提升充电效率,宽温适应不同环境。
  5. 工业控制电路:PLC输入输出模块、传感器调理电路,宽结温满足工业现场高低温变化。

五、选型与替换参考

实际设计中可灵活调整:

  • 同系列升级:需更高电流选ES2DB(2A),更高耐压选ES1GB(400V)。
  • 兼容替换:同参数兼容型号包括US1D、1N4933等,需注意封装一致性(SMB)。
  • 降额建议:实际工作反向电压不超160V(80%降额),电流不超0.8A(80%降额),延长使用寿命。

ES1DB以平衡的性能与高性价比,成为小功率电子设备中快恢复整流的主流选择,适配多数中低压高频应用场景。

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
