LMBR1200FT1G 产品概述
一、概述
LMBR1200FT1G 是乐山无线电（LRC）推出的一款独立式肖特基二极管，封装为 SOD-123FL，面向中等功率、高压场景。该器件在保证开关速度快、正向压降低的前提下，具备 200V 的直流反向耐压和 1A 的整流电流能力，适合各类开关电源、整流与保护电路使用。
二、主要参数
- 二极管配置：独立式（Discrete）
- 正向压降（Vf）：0.92V（典型值）
- 直流反向耐压（Vr）：200V
- 额定整流电流：1A
- 反向电流（Ir）：500µA（在额定条件下）
- 工作结温范围：-55℃ ~ +150℃
- 非重复峰值浪涌电流（Ifsm）：30A
- 封装：SOD-123FL
- 品牌：LRC（乐山无线电）
三、性能特点
- 肖特基结构带来极短的反向恢复时间，适合高频开关场合，能明显降低开关损耗。
- 200V 的高反向耐压使其可在较高电压直流母线或反向应力场合使用。
- Vf ≈0.92V，在同等级高压肖特基中表现平衡，兼顾导通损耗与耐压能力。
- 峰值浪涌电流 30A 提供良好的抗浪涌能力，适用于启动或短暂过载情形。
- 宽温工作结温增强可靠性，适应工业级温度范围。
四、典型应用
- 开关电源整流与续流二极管（反激、正激、同步整流辅助）
- 电池充电与保护电路、反向极性保护
- LED 驱动、适配器与充电器输出整流
- 工业控制、仪器设备中的高压整流与钳位应用
- 低损耗、高频开关场合的续流与钳位电路
五、设计与焊接建议
- 布局方面：将二极管放置于关键电流回路附近，尽量缩短回流路径，减小寄生电感。对散热要求高的应用建议在焊盘处配合铜箔散热或热焊盘过孔。
- 反向漏电：肖特基二极管的反向漏电随温度显著上升，设计时需考虑在高温工况下 Ir 会增大，必要时采取并联或降温措施。
- 浪涌保护：Ifsm 为30A，在存在更大浪涌的应用场合建议配合保险丝或限流元件。
- 焊接工艺：采用 SMD 回流焊工艺时，请遵循器件供应商的焊接曲线与回流温度限制，避免超温导致封装或焊盘损伤。
六、注意事项与可靠性
- 在长期可靠性设计中，建议对结温进行热仿真与实测，确保在最大环境温度和功耗条件下结温不超过规范限值。
- 由于 Vf 与 Vr、漏电之间存在设计折衷，选型时应综合考虑系统电压、效率与温升。
- 采购时确认包装形式（散装/卷装）与质量检验报告，以保证批次一致性。
总结：LMBR1200FT1G 以其 200V 耐压、1A 整流能力与肖特基特性，在中高压、高频整流与保护应用中具有良好性价比。合理的热管理与电路保护能发挥其最佳性能。

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.
