S-LBZT52C43T1G是乐山无线电(LRC)推出的小功率表面贴装稳压二极管,针对便携式电子、工业控制、通信设备等领域的低功耗稳压需求设计。核心优势集中在三个维度:
该型号的电气性能围绕稳压稳定性、功耗控制展开,核心参数需重点关注:
标称稳压值为43V,稳压范围覆盖40V~46V(典型工作电流下的精度区间),可满足中等电压等级的基准或稳压需求。需注意:稳压值随工作电流、温度有微小波动,但在额定范围内波动可控(温度系数约0.05%/℃,参考同类器件典型值)。
最大耗散功率(Pd)为500mW,结合标称稳压值计算,最大工作电流(Izmax)约为11.6mA(Izmax=Pd/Vz≈500mW/43V);最小工作电流(Izmin)通常为1mA左右(需保证电路中工作电流处于该区间,否则稳压效果不稳定)。
反向漏电流(Ir)仅100nA(@32V),远低于稳压值(43V)的反向偏置下,漏电流对电路功耗的影响可忽略,特别适合电池供电的便携式设备(如智能手环、无线传感器)的待机稳压场景。
工作结温范围为**-55℃~+125℃**,符合工业级器件的温度要求,可在户外工业控制箱、车载电子等极端环境中稳定工作。
该型号采用SOD-123表面贴装封装,是小功率稳压管的主流封装之一,具有以下特点:
结合参数特性,S-LBZT52C43T1G适用于以下场景:
S-LBZT52C43T1G作为LRC的小功率稳压管,以低漏电流、宽温范围、小封装为核心亮点,覆盖了便携式、工业、通信等多领域的稳压需求,是中等电压等级低功耗应用的可靠选择。

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.
