LBZT52B24T1G是乐山无线电(LRC) 推出的独立式稳压二极管,属于LBZT52B系列贴片稳压管。该型号专为小功率电路的稳压/基准电压需求设计,采用SOD-123 小型贴片封装,体积紧凑,适配表面贴装(SMT)自动化生产,是消费电子、工业控制等领域的常用稳压元件。
该型号的关键电性能参数针对性地优化了小功率场景的稳压稳定性,核心参数如下:
标称稳压值为24V,稳压范围覆盖23.72V~24.78V,精度约为±2.2%(基于标称值计算)。该范围满足大多数通用电路对稳压精度的需求,无需额外校准即可用于普通电源稳压、基准电压源等场景。
在19V反向偏置下,反向漏电流(Ir)仅为100nA(纳安级),远低于同类产品的典型值(通常为μA级)。低漏电流意味着反向功耗极小,可显著降低电路待机损耗,适合电池供电的低功耗设备(如智能手环、物联网传感器节点)。
最大耗散功率(Pd)为500mW,适配小功率电路(如5V/1A电源的辅助稳压);动态阻抗(Zzt)为120Ω,该参数反映稳压管的稳压能力——阻抗越低,电流变化对输出电压的影响越小。120Ω的阻抗可保证在工作电流波动1mA时,输出电压波动控制在0.1V以内,满足单片机ADC参考电压等对电压稳定性要求较高的场景。
SOD-123是一款小型化贴片封装,尺寸约为1.6mm×0.8mm×0.6mm(典型值),具有以下优势:
该产品的工作结温范围为**-55℃~+150℃**,覆盖工业级环境的温度波动(如户外传感器、车载电子的低温启动/高温工作场景),可靠性表现如下:
总结:LBZT52B24T1G是一款性能均衡的小功率稳压二极管,以紧凑封装、低漏电流、宽温适应性为核心优势,适用于消费电子、工业控制、物联网等多领域的稳压/基准电压需求,是替代同类进口产品的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
