ES2D 是伯恩半导体(BORN)推出的一款快恢复/高效率整流二极管,封装为SMA(DO-214AC)。其典型电气参数为:正向压降 Vf = 950mV @ 2A,直流反向耐压 Vr = 200V,额定整流电流 2A,反向电流 Ir = 5µA @ 200V,反向恢复时间 Trr = 35ns,工作结温范围 -55℃~+150℃。该器件适用于开关电源、整流与保护等需要快速恢复与低漏电特性的场合。
在 2A 正向条件下,器件上的功耗约为 P = Vf × I ≈ 0.95V × 2A ≈ 1.9W。由于封装为SMA,散热主要依赖PCB铜箔面积与良好的布局设计,建议在高电流或连续工作场景下采用更大的散热铜箔或在附近留出热散路径,并进行适当的电流降额设计以保证长期可靠性。
ES2D 采用 SMA (DO-214AC) 表贴封装,适合自动贴装与回流焊工艺。SMA 封装体积小、可靠性好,便于在密集PCB布局中使用。建议参考厂商数据手册中的焊盘布局与回流曲线,以确保焊接质量及良好散热。
ES2D 由伯恩半导体(BORN)生产,适合要求性价比与可靠性的量产应用。选购时请确认完整型号与批次信息,并索取最新数据手册与认证资料(如有需 RoHS/REACH 等合规性证明),以满足项目的质量与合规要求。
总结:ES2D(SMA)以其 200V 耐压、2A 额定电流、35ns 快恢复及低反向漏电的组合,适合多数中功率整流与保护场景,在保证良好热设计的前提下可提供稳定的整流性能与较高的系统效率。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
