SR24_R1_00101 产品概述

一、产品简介

SR24_R1_00101 是 PANJIT(强茂)出品的一款独立整流二极管,面向中功率开关电源、整流和保护电路应用。该器件额定直流整流电流为 2A,反向耐压 40V,正向压降仅 0.5V(在 2A 条件下),在需要低损耗、高可靠性的场合具有良好性价比。器件工作结温范围宽(-55℃ 至 +150℃),并能承受较大的瞬态浪涌电流(非重复峰值浪涌 Ifsm = 50A),适用于对浪涌和热稳定性有要求的电源设计。

二、主要技术特点

  • 额定整流电流:2A(连续直流)
  • 正向压降(Vf):0.5V @ 2A(低导通损耗,有利于提高效率并降低热耗)
  • 直流反向耐压(Vr):40V,适合 12V/24V 电源及机电设备保护场合
  • 非重复峰值浪涌电流(Ifsm):50A,支持短时大电流冲击(如输入浪涌、启动冲击)
  • 工作结温:-55℃ ~ +150℃,适应宽温环境
  • 封装形式:DO-214AC 表面贴装封装,适合自动化贴装与回流焊工艺
  • 品牌:PANJIT(强茂),产品具有工业级可靠性保证

三、典型应用场景

  • 开关电源与整流模块(桥式或单个整流)
  • 反向极性保护与电源输入保护(40V 额定适用于常见低压系统)
  • 续流/钳位二极管,配合电感性负载(马达驱动、继电器、线圈)
  • 电池充放电管理与二次保护电路
  • 工业与家电电源接口,UPS、充电器等需短时承受浪涌的场合

四、封装与热管理建议

SR24_R1_00101 采用 DO-214AC 表面安装封装,适合 SMT 生产线。为获得更好的热性能与长期可靠性,建议在 PCB 设计时:

  • 为器件引脚和焊盘设计足够的铜卷积面积以扩散热量;必要时在焊盘下方或周围配若干过孔连接至内部或背面铜层;
  • 保持引脚到散热铜箔的短连接路径,减少寄生阻抗;
  • 在高温或高平均功率应用中留意器件结温,必要时通过外部散热片或风冷增强散热;
  • 遵循厂商推荐的回流焊温度曲线与焊接工艺,以避免封装材料应力或性能退化。

五、使用与注意事项

  • 非重复峰值浪涌 Ifsm 为短时规范值(通常按 JEDEC 半正弦波 8.3ms 条件测试),长期重复的大浪涌会缩短器件寿命;在需要频繁冲击的场合应增加浪涌限流或吸收器件(如 TVS、电抗);
  • 典型电源设计应考虑 Vf 带来的功耗(P = If × Vf),以估算结温上升并确认散热设计;
  • 器件工作于较高环境温度时,应留有温度裕量并避免与高发热元件布置过近;
  • 储存与焊接请参考 PANJIT 的具体焊接与存储规范,防潮包装和回流曲线应遵循以保障焊接可靠性。

六、规格摘要(关键参数)

  • 型号:SR24_R1_00101(PANJIT)
  • 封装:DO-214AC(表面贴装)
  • If(整流电流):2A
  • Vf:0.5V @ 2A
  • Vr(反向耐压):40V
  • Ifsm(非重复峰值浪涌):50A
  • 工作结温:-55℃ ~ +150℃

总结:SR24_R1_00101 以其低正向压降、良好的浪涌能力和宽工作温度范围,适合中功率、耐冲击的整流与保护应用。在 PCB 热管理和浪涌场景设计上给予足够重视,可以发挥其高效、可靠的特性。若需详细电气特性曲线、封装尺寸图或回流焊建议,请参考 PANJIT 官方数据手册或联系供应商获取原厂资料。

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
