S3MA_R1_00001 产品概述

一、产品概述

S3MA_R1_00001 是 PANJIT(强茂)推出的一款通用独立式整流二极管,采用 SMB (DO-214AA) 封装。器件为独立配置,额定直流整流电流为 3A,反向耐压高达 1kV,适合中高压整流与保护应用。该型号在常规功率转换与整流场合表现稳定,具有低漏电与良好的浪涌承受能力,是电源、变频及充电设备常用的选择。

二、主要电气参数

  • 正向压降 (Vf):1.2V @ If = 3A
  • 直流反向耐压 (Vr):1000V (1kV)
  • 额定整流电流:3A(直流)
  • 反向漏电流 (Ir):1μA @ Vr = 1kV
  • 非重复峰值浪涌电流 (Ifsm):200A(单次半波)
  • 工作结温范围:-55℃ ~ +150℃
  • 二极管配置:独立式

三、主要特点与优势

  • 高耐压:1kV 的反向耐压使其适用于高压整流与抑制电路,能胜任开关电源次级整流、HVDC 较低功率段等场合。
  • 低正向压降:在 3A 工作点 Vf 仅 1.2V,有助于降低整流损耗和发热,提高效率。
  • 低反向漏电:在额定耐压下 Ir 典型值为 1μA,利于高阻抗回路与待机功耗敏感的电路设计。
  • 强浪涌能力:200A 的非重复峰值浪涌电流保障器件在突发浪涌或充电电容器时的鲁棒性。
  • 宽温度范围:-55℃ 至 +150℃ 的结温范围支持工业级应用与苛刻环境。

四、典型应用

  • 开关电源(SMPS)整流与钳位电路
  • 工业电源与逆变器输出整流
  • 电池充电器与适配器整流元件
  • 功率模块的保护与吸收电路
  • 电子镇流器与灯具驱动器中高压整流

五、封装与热管理建议

SMB(DO-214AA)封装提供了良好的机械强度与散热路径,便于手工焊接和波峰或回流焊工艺。然而在 3A 连续工作或高频整流场合仍应关注 PCB 散热设计:

  • 建议在封装底部及周边铺设充足的铜箔(散热墩或散热岛),并通过过孔与下层铜平面连接以增强散热。
  • 在高温环境或靠近额定极限时,应考虑适当的额定电流降额(derating),或使用外加散热片 / 强化散热的 PCB 设计。
  • 遵循制造商的回流焊温度曲线与峰值温度限制,避免多次高温循环导致封装损伤。

六、可靠性与使用注意

  • ESD 与浪涌保护:尽管 Ifsm 为 200A,但在频繁或未知的冲击环境下仍建议在系统层面增加浪涌保护元件(如 TVS 或限流元件)。
  • 储存与焊接:长时间储存应保持防潮包装,焊接时应避免超过推荐的回流温度和时长,以防损伤封装或内部焊点。
  • 极性识别:装配时注意阳极/阴极方向,SMB 封装通常在封装端面或标记处标识极性。

七、选型建议

在选用 S3MA_R1_00001 时,如工作电流、环境温度或热阻要求超过其额定能力,建议:

  • 评估最大结温并按制造商建议进行电流降额;
  • 若需更低正向压降或更高电流能力,可考虑并联器件或选择更高规格封装的整流二极管;
  • 对于更严格的浪涌或重复冲击场合,选择具有更高 Ifsm 或专用浪涌抑制器件。

简而言之,S3MA_R1_00001 是一款面向工业与通用电源整流的高压、低漏电、可靠性良好的独立式二极管,适用于需要 1kV 等级耐压与 3A 持续整流能力的设计。

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
