S-LBZT52C7V5T1G是乐山无线电(LRC)推出的表面贴装稳压二极管,属于LBZT52系列通用稳压管范畴,针对小功率稳压、基准电压源及过压保护等场景优化设计,具备宽温度适应性、低漏电流及紧凑封装等核心优势。
该器件以7.5V标称稳压值为核心设计目标,关键参数清晰覆盖设计与选型需求:
参数项 规格值 备注 标称稳压值(Vz) 7.5V 典型应用基准电压 稳压值范围 7.0V ~ 7.9V 覆盖生产误差与温度漂移 反向漏电流(Ir) 1μA @ 1.0V反向偏置 低功耗场景关键指标 耗散功率(Pd) 500mW 最大允许功耗 动态阻抗(Zzt) 15Ω 稳压工作点的动态阻抗 测试阻抗(Zzk) 80Ω 特定测试条件下的阻抗 工作结温范围 -55℃ ~ +150℃ 宽温适应性 封装形式 SOD-123 小型表面贴装封装 品牌 乐山无线电(LRC) 国内知名半导体厂商标称稳压值7.5V为电路设计提供明确基准,7.0V~7.9V的稳压范围覆盖了生产过程中的参数离散性及工作温度变化带来的漂移,无需额外复杂补偿电路即可满足多数通用稳压需求。
在1.0V反向偏置(未击穿状态)下,反向漏电流仅1μA,这一特性使其在低功耗场景(如便携式设备待机模式)中表现优异——未进入稳压工作时几乎不消耗额外电流,有效延长电池续航。
最大耗散功率500mW,结合7.5V标称稳压值,计算得最大允许稳压电流约为66.7mA(P=Vz×Iz),可覆盖多数小型电路的稳压需求(如单片机电源、小功率传感器供电等)。
采用SOD-123表面贴装封装,尺寸约为2.9mm×1.6mm×1.1mm,体积小巧,适合高密度PCB布局(如智能手机、智能穿戴设备等小型化产品);封装引脚间距合理,焊接兼容性好,可通过回流焊、波峰焊等常规工艺实现。
工作结温覆盖**-55℃~+150℃**,满足工业级、汽车级(部分场景)及消费电子的宽温需求——可在低温环境(如北方户外设备)或高温环境(如车载电子、电源模块内部)稳定工作,无需额外散热设计(小功率场景下)。
LRC作为国内成熟半导体厂商,该器件通过了常规可靠性测试(如温度循环、湿度老化、焊接可靠性等),确保批量应用中的一致性与稳定性。
S-LBZT52C7V5T1G的特性使其适配以下场景:
综上,S-LBZT52C7V5T1G凭借稳定的稳压特性、低功耗设计、紧凑封装及宽温适应性,成为通用小功率稳压与保护场景的高性价比选择,可广泛应用于消费电子、工业控制、通信等领域。

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.
