RB160M-40 产品概述
一、产品简介
RB160M-40 是 CJ（江苏长电/长晶）出品的一款独立式肖特基二极管，采用 SOD-123 小封装，面向低压高频开关和整流场景。器件在 1A 工作电流时表现出优异的低正向压降（Vf = 0.51V@1A），直流反向耐压为 40V，适用于空间受限且需降低导通损耗的应用。
二、主要特性
- 肖特基结构，低正向压降：Vf = 510mV @ 1A，可显著降低导通损耗。
- 额定整流电流：1A，满足多数小功率电源和保护电路需求。
- 反向电压：Vr = 40V，适合 12V/24V 级别的系统。
- 低反向漏电流：Ir = 30µA @ 40V（室温标称），在高温下会有所上升需注意。
- 非重复峰值浪涌电流 Ifsm = 15A，具备一定的抗冲击能力用于瞬态吸收。
- SOD-123 封装，适合自动贴装和高密度 PCB 布局。
三、电气与热特性说明
在 1A 连续工作时，二极管的功耗约为 P = Vf × I ≈ 0.51W；由于 SOD-123 封装散热有限，建议在 PCB 设计中配合适量铜箔散热（焊盘和散热铜皮）并进行电流降额以保证可靠性。反向漏电随温度上升显著增加，温度敏感场合需在选型和热设计时预留裕量。Ifsm 为非重复瞬态能力，能在突发浪涌时提供保护，但不作为长期过载手段。
四、典型应用场景
- 开关电源输出整流与续流二极管
- 逆向电流保护（电源反接保护、二极管 OR-ing）
- DC-DC 转换器、充电电路、汽车电子（低压部分）
- 小功率适配器、通信设备和消费类电子的快速恢复/整流应用
五、选型与使用建议
- 连续电流接近 1A 时，应在 PCB 上扩大铜箔面积并采用多层散热设计；必要时按实际环境和温升进行电流降额。
- 留意反向漏电随温度变化，工作在高温、高阻态应用时需验证实际漏电是否满足系统要求。
- 焊接建议遵循 JEDEC/J-STD-020 回流曲线，SOD-123 适合回流焊贴装；手工焊接时避免过热焊点。
- 对于含瞬态冲击的系统，确认 Ifsm 能覆盖预期浪涌并考虑串联熔断或限流保护以提升可靠性。
- 储运和装配环节注意静电防护（ESD），并按厂商推荐的封装方向和焊盘设计布局。
六、可靠性与封装
CJ（江苏长电/长晶）出品，SOD-123 封装尺寸紧凑，适配自动贴装与卷盘供料。器件适用于量产电子制造，建议在量产前进行样片验证（包括热测试、寿命试验和浪涌测试），以确保在目标应用中的长期可靠性。
总之，RB160M-40 以其低正向压降和紧凑封装，适合要求降低导通损耗、空间受限的低压整流与保护场景。设计时重点关注 PCB 散热与温度下的漏电管理，可获得稳定且高效的系统表现。

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.
