S-LBZX84C4V7LT1G稳压二极管产品概述

一、产品核心定位与应用场景

S-LBZX84C4V7LT1G是乐山无线电(LRC)推出的独立式表面贴装稳压二极管,专为小型化、低功耗电子设备的电压基准或过压保护设计。其核心定位是提供稳定的4.7V基准电压,适配对空间紧凑、宽温可靠性有要求的场景,典型应用包括:

  1. 便携电子设备:智能手机、蓝牙耳机、智能手环等低功耗终端的电源稳压模块;
  2. 工业控制电路:PLC、传感器节点的基准电压源,适配-55℃~+150℃的宽温环境;
  3. 汽车电子:车载中控、胎压监测传感器的辅助稳压,满足汽车级温度要求;
  4. 消费类电子:机顶盒、路由器、智能家居设备的电源滤波与过压保护;
  5. 通信设备:小型基站、无线模块的电压调节电路。

二、关键电气性能参数

该产品的核心参数经过优化,平衡了稳压精度、功耗与可靠性,关键指标如下:

  • 稳压值:标称4.7V,实际工作范围4.4V~5.0V,覆盖常见低压基准需求,满足电路电压裕量要求;
  • 反向漏电流(Ir):典型值3uA,大幅降低静态功耗,适合电池供电的便携设备;
  • 耗散功率(Pd):最大300mW,典型应用下可稳定承载225mW以内的功率损耗,适配中小功率电路;
  • 动态阻抗(Zzt):80Ω(稳压电流下),稳压性能稳定,输出电压波动极小;
  • 工作结温:-55℃~+150℃,符合工业级与汽车级温度标准,极端环境下长期可靠。

三、封装与可靠性设计

  1. 封装形式:采用SOT-23小型表面贴装封装,尺寸紧凑(约2.9mm×1.6mm×1.1mm),适配高密度PCB设计,降低设备体积;
  2. 可靠性设计:
    • 宽温兼容:覆盖-55℃至+150℃,支持工业、汽车等极端温度场景;
    • 低功耗特性:3uA反向电流减少静态损耗,延长电池续航;
    • 机械稳定性:SOT-23封装抗振动、冲击性能优异,适配回流焊工艺。

四、典型应用电路参考

1. 简单稳压电路

在5V电源输出端串联100Ω限流电阻,并联S-LBZX84C4V7LT1G,即可获得稳定的4.7V基准电压,适用于单片机(MCU)参考电压输入;

2. 过压保护电路

将二极管反向并联在敏感电路输入端,当输入电压超过4.7V时,二极管击穿导通,钳位电压至4.7V左右,保护后级电路;

3. 电池供电稳压

配合升压/降压芯片,该稳压管作为基准电压源,稳定输出4.7V,满足低功耗设备供电需求。

五、选型与使用注意事项

  1. 限流电阻计算:需根据电路工作电流计算限流电阻,避免稳压管过功率损耗(Pd≤300mW);
  2. 温度适配:极端温度(如+150℃)下需优化PCB散热,避免结温过高;
  3. 焊接工艺:回流焊温度≤260℃、时间≤30s,符合SOT-23封装焊接要求;
  4. 存储条件:存储温度-65℃~+150℃,避免潮湿,未开封存储周期≤12个月。

该产品凭借小型化、宽温可靠、低功耗等优势,成为便携设备、工业控制、汽车电子等领域的优选稳压器件。

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.

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
