SRM54AVF_R1_00001 — PANJIT 强茂 肖特基二极管 产品概述
一、产品简介
SRM54AVF_R1_00001 是强茂（PANJIT）出品的一款高性能肖特基整流二极管，封装为 SMBF，额定整流电流 5A，直流反向耐压 45V。该器件在 5A 工作电流下典型正向压降仅 430mV，具备低导通损耗、快速响应和良好的冲击承受能力，适用于中低压电源和开关电源保护场合。
二、主要电气参数
- 工作结温范围：-55℃ ~ +150℃
- 正向压降 Vf：430mV @ 5A（典型）
- 平均整流电流：5A
- 非重复峰值浪涌电流 Ifsm：150A
- 直流反向耐压 Vr：45V
- 反向电流 Ir：70μA @ 36V
- 封装：SMBF（表面贴装）
三、关键特性与优势
- 低正向压降：减小导通损耗，提高整流效率，适合高效电源设计。
- 快速恢复与肖特基特性：低反向恢复时间，适用于高频开关场景，降低开关损耗与电磁干扰。
- 良好浪涌能力：150A 的非重复峰值浪涌电流可应对瞬态过载与开机冲击。
- 宽工作温度：-55℃ 至 +150℃，适应工业与汽车级较苛刻环境（在允许的电气和热条件下）。
四、典型应用
- 开关电源 (SMPS) 的输出整流
- DC-DC 转换器和降压模块的续流/钳位二极管
- 车载电源系统（12V/24V）中的整流与反向保护（注意 45V 的极限）
- 电池 ORing、功率管理与逆接保护
- 其他需要低压降、高效率整流的电源与负载保护场景
五、热设计与使用建议
- 在最大额定电流 5A 工作时，功耗约为 P ≈ Vf × I ≈ 0.43V × 5A ≈ 2.15W，需合理考虑 PCB 散热：增加散热铺铜与热通孔，尽量缩短焊盘到大铜箔的路径。
- 在高脉冲或高环境温度下，应进行电流降额，保证结温不超过最高允许值。
- 建议按器件规格书采用推荐焊盘尺寸与回流焊曲线，避免过热损伤封装或影响长期可靠性。
六、可靠性与封装
- SMBF 表面贴装封装利于自动化贴装与回流焊接，具有紧凑尺寸与良好机械强度。
- 按 IPC/JEDEC 标准进行存储与湿敏等级处理，遵循制造商推荐的焊接温度规范以确保长期稳定性。
七、选型与采购建议
- 若系统电压或瞬态可能超过 45V，请选择更高 Vr 的型号或增加抑制元件（TVS）。
- 对于要求更低正向压降或更高电流能力的设计，可参考 PANJIT 的其他肖特基系列或并联使用注意热均衡与电流分享。
- 订购时请确认完整料号 SRM54AVF_R1_00001 与批次信息，必要时索取器件规格书与可靠性报告以便验证。
如需我提供典型电路接法、PCB 布线建议或根据您具体应用（例如 12V 转 5V 输出整流）做更详细的热与电气仿真估算，可告知工作条件与电路参数。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
