BZT52C5V1T是伯恩半导体(BORN)推出的一款小型表面贴装稳压二极管,专为低功耗、高密度电子设计场景打造,核心功能是提供稳定的5.1V参考电压,广泛适配便携设备、小型电源等领域。
该器件属于伯恩半导体稳压管系列中的通用低功率型号,伯恩半导体作为国内功率器件领域的成熟厂商,其产品以一致性好、可靠性高著称。BZT52C5V1T继承了品牌的稳定特性,针对小空间、低功耗需求优化,是5V系统稳压的高性价比选择。
标称稳压值为5.1V,实际工作范围覆盖4.8V~5.4V,精度约±6%,满足多数通用电路的稳压需求(如5V电源的辅助稳压、传感器参考电压)。该参数在指定测试电流下测得,批量产品一致性良好。
最大耗散功率(Pd)为200mW,属于小功率稳压器件。结合标称稳压值计算,最大允许连续工作电流约39mA(I=Pd/Vz≈200mW/5.1V),适合小电流稳压或过压保护,不推荐大功率负载应用。
反向漏电流(Ir)仅2uA,远低于常规稳压管水平,这一特性使其在低功耗场景(如物联网终端、电池供电设备)中表现优异,可有效降低待机功耗。
BZT52C5V1T采用SOD-523封装,这是一种超小型表面贴装封装,具体尺寸为:
该封装的核心优势:
封装带色带标识负极,安装时需注意极性(色带端接电路正极),反向接入会导致器件短路烧毁。
总结,BZT52C5V1T凭借小封装、低漏电流、稳定稳压特性,成为便携电子、低功耗电路中5V稳压的理想选择,适合对空间和功耗敏感的设计需求。
Request for quote
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.
