LRB550V-30T1G肖特基二极管产品概述

LRB550V-30T1G是乐山无线电(LRC)推出的一款独立式肖特基二极管,针对低电压小功率电路做了针对性优化,凭借低正向压降、超小封装、高可靠性等特点,广泛适用于便携电子、物联网终端及消费类设备的整流、续流与反向保护场景。

一、产品核心定位与应用场景

肖特基二极管因金属-半导体接触结构,天生具备「正向压降低、开关速度快」的核心优势,而LRB550V-30T1G在此基础上,精准匹配了两类典型需求:

  • 「低功耗敏感场景」:如电池供电的智能穿戴、蓝牙耳机,需降低电源损耗延长续航;
  • 「高密度空间场景」:如小型物联网传感器、便携设备PCB,需超小封装节省布局空间。

其30V反向耐压、500mA持续电流的参数组合,覆盖了大多数低电压电路的常规工况,是便携电子、小型电源模块的理想选择。

二、关键电性能参数解析

该器件的核心参数围绕「低损耗、高可靠性」设计,具体解析如下:

  1. 正向压降(Vf=600mV):比普通硅整流二极管(典型0.7V)低14%,导通时能量损耗更小,直接提升电池供电设备的续航能力;
  2. 直流反向耐压(Vr=30V):满足低电压电路的反向截止需求,避免电路反向过压(如电池反接、电源波动)损坏;
  3. 持续整流电流(If=500mA):可稳定承载0.5A的持续工作电流,覆盖小型电子设备的常规功率需求(如LED驱动、传感器供电);
  4. 反向漏电流(Ir=30μA):反向漏电流极小,静态功耗低,进一步提升电路效率;
  5. 非重复峰值浪涌电流(Ifsm=2A):能承受瞬间2A的脉冲冲击(如电路启动、负载突变),避免瞬态工况下器件损坏。

三、封装与可靠性设计

该器件采用SOD-323表面贴装封装,尺寸约1.6mm×0.8mm×0.6mm,属于超小型封装,可大幅节省PCB空间,适配高密度电路设计(如智能手环、蓝牙耳机的迷你主板)。

封装材料采用耐高温环氧树脂,符合RoHS 6无环保标准,同时具备以下可靠性优势:

  • 耐湿、耐振动:适应便携设备的跌落、振动环境;
  • 快开关特性:无反向恢复时间,避免开关过程中的能量损耗与电磁干扰,提升电路稳定性。

四、品牌与品质保障

乐山无线电(LRC)是国内半导体行业老牌企业,拥有超过50年的二极管/三极管制造经验,产品覆盖消费电子、汽车电子、工业控制等领域。LRB550V-30T1G经过严格的生产管控:

  • 自动化封装+全参数测试:保证参数一致性,适合批量生产;
  • 国际标准认证:通过JEDEC等认证,满足工业级/消费级可靠性要求。

五、典型应用示例

  1. 蓝牙耳机充电盒:作为充电电路的整流二极管,低Vf减少充电损耗,提升充电效率;
  2. 智能手环电源模块:用于锂电池输出的续流保护,避免电机负载反向电流损坏电池;
  3. 物联网温湿度传感器:在信号处理电路中做过压钳位,保护敏感元件;
  4. 小型LED驱动电路:配合开关管做续流二极管,提升LED驱动效率与稳定性。

LRB550V-30T1G凭借「低功耗、小封装、高可靠性」的综合优势,成为低电压小电流电路中整流、续流及保护的优选器件,能有效满足便携电子与物联网终端的设计需求。

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
