SVM1545LB_R2_00001 产品概述

一、产品简介

SVM1545LB_R2_00001 为强茂(PANJIT)出品的一款功率肖特基二极管,采用 TO-277B 封装,面向中低压大电流整流与保护场合。该器件以极低的正向压降和快速响应特性著称,适用于开关电源、DC-DC 变换器、整流桥、续流二极管及反向保护电路等功率应用。

二、主要电气参数

  • 正向压降 (Vf):0.490 V @ If = 15 A(典型)
  • 直流反向耐压 (Vr):45 V
  • 额定整流电流:15 A
  • 反向电流 (Ir):320 μA @ Vr = 45 V
  • 非重复峰值浪涌电流 (Ifsm):275 A
  • 工作结温范围:-55 ℃ ~ +150 ℃

三、关键特性与优势

  • 低正向压降:0.49 V 在 15 A 时可显著降低导通损耗,提高效率,尤其适合高电流密度的整流场合。
  • 快速恢复/肖特基特性:极小反向恢复电荷,适合高频开关应用,减少开关损耗与电磁干扰。
  • 宽温度范围:-55 ℃ 至 +150 ℃ 的结温能力提高了在恶劣环境下的可靠性。
  • 高浪涌承受能力:275 A 的非重复峰值浪涌电流,可应对短时启动电流和突发冲击。
  • 紧凑封装:TO-277B 有利于散热并便于板上安装与可靠焊接。

四、典型应用场景

  • 开关电源(SMPS)输出整流与输入整流
  • DC-DC 转换器与电源模块
  • 马达驱动与电机控制的续流二极管
  • 逆电流/反接保护
  • 汽车电子(非高压总线)与工业电源系统

五、封装与热管理建议

TO-277B 封装利于通过金属散热片或铜箔 PCB 进行热传导。设计时建议:

  • 在 PCB 上提供充足的铜面积作为散热层,并通过多孔过孔与底部散热层热连接。
  • 在长时间 15 A 工作点下进行热仿真与结温评估,必要时采用外部散热片或风冷。
  • 注意封装端子和焊点的可靠焊接性,避免因焊接不良导致接触电阻上升。

六、可靠性与使用注意事项

  • 请按器件额定值与热阻进行电流/温度降额使用,避免长期在极限工况下运行。
  • 反向电流随温度显著上升,高温条件下应谨慎考虑泄漏导致的功耗。
  • 非重复峰值浪涌仅用于短时冲击(如开机浪涌),不应用作重复循环冲击的评估依据。
  • 推荐参考强茂官方数据表获取更详尽的电气特性曲线与焊接/回流工艺参数。

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
