ES1D 产品概述
一、产品简介
ES1D 是 DIOTEC（德欧泰克）出品的一款 Superfast 整流二极管，采用 SMA（DO-214AC）表面贴装封装，适用于中高频开关电源与通用整流场合。器件额定反向耐压 200V，平均整流电流 1A，结温可承受 -50℃ 至 +150℃，具有快速恢复特性与良好的浪涌承受能力，便于在体积受限的 SMD 应用中替代传统快恢复二极管。
二、主要电气参数
- 正向压降 (Vf)：0.92 V @ IF = 1 A
- 反向耐压 (Vr)：200 V
- 平均整流电流：1 A
- 反向漏电流 (Ir)：5 µA @ VR = 200 V
- 反向恢复时间 (Trr)：15 ns（Superfast 级别）
- 非重复峰值浪涌电流 (Ifsm)：33 A
- 工作结温范围：-50℃ ~ +150℃
以上参数体现了 ES1D 在中等电流与高电压场合的实用性：较低的正向压降降低导通损耗，快速恢复时间适合高频开关环境，较小的反向漏电流有利于提高效率和降低待机功耗。
三、典型应用场景
- 开关电源（SMPS）输出整流和续流二极管
- 充电器与适配器的整流与保护电路
- DC-DC 变换器中的续流二极管（降压/升压）
- 通用电源模块、功率滤波与反向保护电路
- 脉冲或间歇性高浪涌的电源线路
四、封装与热管理
ES1D 所用 SMA（DO-214AC）封装适配表面贴装工艺，封装体积小、热阻适中。为保证长期可靠性与高电流能力，建议在 PCB 设计时：
- 增大焊盘及下方铜箔面积以提高散热能力；
- 在高平均电流或高环境温度条件下进行电流整定/降额；
- 按制造商推荐的回流焊曲线进行焊接，避免超温或快速冷却造成热应力。
五、选型与替代建议
若设计要求更低的正向压降或更高频率工作，可考虑肖特基二极管，但需权衡其较高的反向漏电流与较低的耐压能力。若系统强调高耐压且容许较慢恢复时间，可选用标准快恢复或普通整流器件。本型号适合在 200V 环境下要求 1A 连续整流且需快速恢复的场合。
六、可靠性与使用注意
ES1D 具有良好的浪涌承受能力（Ifsm 33A），适合短时突发冲击电流。使用时应注意：
- 按照电路实际工作温度对额定电流进行降额；
- 在高湿或强振动环境下注意焊点与封装的可靠性检测；
- 如需精确设计，请参考完整数据手册以获取温度依赖特性曲线、功耗曲线及封装引脚尺寸。
总结：ES1D 是一款面向中等功率、需快速恢复与高耐压场合的可靠 SMD 整流二极管，适用于各类开关电源、充电器与通用整流保护电路。选择时建议结合实际工作频率、平均电流与散热条件进行合理匹配，以确保系统长期稳定运行。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
