S-LMBZ27VALT1G稳压二极管产品概述

S-LMBZ27VALT1G是乐山无线电(LRC)推出的一款小功率表面贴装稳压二极管,采用共阳极1对配置,核心稳压功能稳定可靠,适配多种小型化电子设备的电压调节与过压保护需求。以下从参数规格、性能优势、封装品牌、应用场景及使用注意事项等维度详细介绍。

一、基本参数与规格定义

该器件的核心参数明确且符合工业级器件标准,关键指标如下:

  • 二极管配置:1对共阳极(内部两个齐纳管共用阳极,两侧引脚为独立阴极);
  • 稳压特性:标称稳压值27V,稳压范围25.65V~28.35V(覆盖±5%精度公差,满足多数普通稳压需求);
  • 电气性能:反向漏电流(Ir)≤50nA(静态功耗极低),最大耗散功率(Pd)250mW(小功率设计适配轻负载);
  • 温度特性:工作结温范围-55℃~+150℃(覆盖工业级与汽车级温度区间,极端环境下稳定工作);
  • 封装标识:封装形式SOT-23(超小型表面贴装),品牌标识为LRC(乐山无线电原厂正品)。

二、关键性能与技术优势

该器件在稳压精度、功耗控制及环境适应性上具备明显优势:

  1. 稳压精度可控:±5%的稳压公差(25.65~28.35V)无需额外校准,可直接作为多数电路的参考电压或过压钳位电压;
  2. 低功耗设计:反向漏电流仅50nA,静态功耗远低于常规稳压管,适合电池供电的便携式设备(如智能穿戴、蓝牙耳机);
  3. 宽温稳定工作:-55℃低温下无启动异常,+150℃高温下稳压特性不衰减,支持工业控制、车载模块等极端环境;
  4. 小尺寸高集成:SOT-23封装体积约1.6×2.9×1.1mm,1对共阳极配置节省PCB空间,可替代单管双封装方案,提升布局密度。

三、封装与品牌背景

  • 封装解析:SOT-23是行业通用超小型表面贴装封装,3引脚设计(中间为阳极,两侧为阴极),适配回流焊、波峰焊等工艺,焊接兼容性强;
  • 品牌保障:乐山无线电(LRC)是国内知名半导体制造商,拥有30余年稳压管生产经验,产品通过ISO9001、IATF16949认证,品质稳定且供货周期可控。

四、典型应用场景

该器件适配多种轻负载稳压与过压保护场景:

  1. 便携式电子稳压:智能手环、蓝牙耳机等设备中,作为升压电路后的稳压环节,为传感器、MCU提供稳定参考电压;
  2. 电源过压保护:开关电源、线性电源输出端并联,当电压超过27V时导通,钳位电压保护后级负载(如模拟电路、通信模块);
  3. 工业控制参考:PLC、温度传感器模块中,作为基准电压源,保证信号采集与处理的精度;
  4. 车载辅助稳压:车载小功率模块(如仪表盘背光、胎压传感器)中,应对12V电源波动,提供稳定的27V辅助电压。

五、选型与使用注意事项

为保证器件可靠性,需注意以下要点:

  1. 负载匹配:最大耗散功率250mW,稳压时最大负载电流≈9.26mA(250mW/27V),需避免负载电流超限导致过热;
  2. 焊接规范:回流焊峰值温度≤260℃,焊接时间≤10秒,防止结温过高损坏器件;
  3. 极性确认:共阳极配置需区分引脚(中间为阳极,两侧为阴极),接反会导致稳压失效;
  4. 散热考虑:工作结温上限150℃,实际使用需保证PCB散热,避免高温环境下长期满负载工作。

总结

S-LMBZ27VALT1G凭借稳定的稳压特性、低功耗、宽温范围与小尺寸设计,成为便携式电子、工业控制、汽车电子等领域的理想稳压器件选择。LRC的品牌保障进一步提升了其可靠性与性价比,适配多种小型化电路的电压调节需求。

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
