S2M-AU_R1_000A1 产品概述

S2M-AU_R1_000A1 是强茂(PANJIT)推出的一款高电压表面贴装整流二极管,采用 SMB 封装(DO-214AA 类),面向需要高反向耐压与可靠整流能力的电源与工业电子场合。器件设计兼顾高压耐受、低正向压降与小漏电特性,适合在受限空间内完成高效整流与浪涌抑制任务。

一、主要特性

  • 单个独立二极管,适用于点对点整流与保护电路。
  • 正向压降:典型 Vf = 1.1V @ 2A,利于降低整流损耗。
  • 直流反向耐压:Vr = 1kV,满足高压整流与阻断需求。
  • 直流整流电流:2A(连续),适合中小功率电源。
  • 反向漏电流:Ir ≈ 1μA(在额定条件下),保证在高压下的低泄漏特性。
  • 非重复峰值浪涌电流(Ifsm):60A,具有良好的浪涌承受能力。
  • 工作结温范围:-55℃ ~ +150℃,适应宽温环境。
  • 封装:SMB 表面贴装,便于自动化装配与焊接。
  • 符合环保要求:HF(无卤)、适配常见无铅回流工艺(请参照强茂推荐的焊接曲线)。

二、主要电气参数(典型/额定)

  • 正向压降(Vf):1.1V @ If = 2A
  • 直流反向耐压(Vr):1000V
  • 额定整流电流:2A(平均/连续)
  • 反向电流(Ir):约 1μA(在额定反向电压及室温条件下)
  • 非重复峰值浪涌电流(Ifsm):60A(单次浪涌承受能力)

注:以上参数以厂方数据为准,实际应用中应根据工作温度、散热条件与频繁浪涌情况做相应裕量设计。

三、典型应用场景

  • 开关电源与高压直流电源的输出整流或保护。
  • 光伏逆变器、充电器与适配器高压侧整流。
  • 工业控制、测量设备中的高压保护与钳位电路。
  • 高频脉冲或浪涌环境下的整流与吸收用途。
  • 任何需要 1kV 等级耐压且空间受限的表面贴装解决方案。

四、封装与热管理建议

  • SMB 表面贴装封装便于在自动贴装与回流焊工艺中使用;封装对PCB散热依赖较大。
  • 在连续 2A 工作电流下,应考虑合理的铜箔面积与散热通道以降低结温。建议在焊盘下方或附近增加散热铜层并与热沉或接地层连通以提升热扩散能力。
  • 对于频繁出现浪涌(Ifsm)或高结温环境,应评估实际峰值能量并预留安全裕量。

五、布局与可靠性建议

  • 二极管的正负端焊盘应设计成与封装匹配的足够面积,以保证可靠焊接与散热。
  • 在高压 PCB 布局时注意安全间距和爬电距离,防止表面击穿或漏电。
  • 对有较高工作温度的应用,应考虑热循环与机械应力对焊点的影响,必要时采用环氧填充或加固措施。
  • 进行浪涌测试与温升评估以确保在目标应用中的长期可靠性。

六、包装与订购信息

  • 品牌:PANJIT(强茂)
  • 型号示例:S2M-AU_R1_000A1(请以采购单与厂方数据表为准)
  • 封装:SMB,适配常规带卷自动贴装(具体包装形式请咨询经销或查看产品数据表)。

结语:S2M-AU_R1_000A1 以其 1kV 的高耐压、较低的正向压降与良好的浪涌承受能力,适合用于各类要求高压整流与可靠性的中小功率电子装置。为确保最佳性能,请在设计初期参考强茂提供的完整器件资料与回流焊曲线,并在目标应用中进行热、浪涌与老化验证。

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
