ES2G 是一款独立式(离散)快恢复、高效率整流二极管,适用于中高压开关及整流场合。由 CJ(江苏长电/长晶)出品,采用SMBG封装,设计用于在要求较高的开关速度和较低开关损耗的电源电路中替代传统慢恢复硅整流器。该器件在2A工作电流下正向压降仅约1.25V,同时具备400V的直流反向耐压和较低的反向漏电流,适合通用电源、电机驱动、照明与家电等应用。
这些参数表明 ES2G 在中等电流和高电压场合具有良好的折衷:既能承受较高的反向电压,又能提供较快的开关响应与较低的正向压降,从而降低导通与开关损耗。
ES2G 采用SMBG(表面贴装)封装,具有以下优势:
在设计PCB时,建议在焊盘周围增加散热铜箔或通过孔,以降低结温并提升长期可靠性。
ES2G 适用于多种需要中等电流、高压、快恢复二极管的场合,例如:
在选型时可将 ES2G 与其他同类快恢复 2A/400V 器件做综合比较,关注正向压降、反向恢复时间、反向漏电流、峰值浪涌能力与封装形式。SMBG 封装适合表面贴装制造流程;如果系统需要更低正向压降或更快恢复,可考虑功率肖特基二极管或更高速的复合型二极管,但需权衡反向承压与漏电流特性。
总结:ES2G 提供了一组平衡良好的电气特性:低至1.25V的正向压降、400V的反向耐压与35ns的快恢复时间,适合用于中高压开关电源与各类整流场合。合理的热设计与瞬态可控措施可最大化其性能与可靠性。若需进一步数据(例如温度系数、动态特性曲线或封装尺寸图),建议参照厂家完整数据手册或联系供应商获取样品与应用支持。

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.
