BZT52C18S是扬杰电子(YANGJIE)推出的一款表面贴装硅稳压二极管,属于BZT52系列通用稳压管范畴。该型号以“18S”标识核心稳压特性,专为小型化、低功耗电子设备的电压基准或过压保护场景设计,采用SOD-323(SC-90)封装,符合工业级可靠性要求,可满足批量生产与复杂环境应用需求。
标称稳压值为18V,实际工作稳压范围覆盖16.8V~19.1V——此范围由制造工艺一致性决定,确保批量应用中电压输出波动可控,无需额外复杂校准即可满足大多数低压稳压场景的精度要求。
在反向电压12.6V(低于标称稳压值) 下,反向漏电流仅100nA,该参数体现了器件反向截止特性优异:低漏电流可有效降低待机功耗,特别适合对功耗敏感的便携式电子设备(如智能手环、蓝牙耳机),避免不必要的能量损耗。
最大耗散功率Pd=200mW,结合标称稳压值计算,其最大允许工作电流约为11mA(200mW÷18V≈11.1mA)。电路设计中需匹配合适的限流电阻,避免超过功耗极限导致器件过热损坏,同时保证稳压功能稳定。
该器件采用SOD-323(SC-90)封装,是一款超小型表面贴装封装(典型尺寸约1.6mm×0.8mm×0.6mm),具有以下核心优势:
BZT52C18S因参数适配性强,广泛应用于以下领域:
工作结温范围覆盖**-55℃~+150℃**,此宽温特性使器件可在极端环境下稳定工作,例如:
综上,BZT52C18S以低功耗、小封装、宽温特性和稳定的稳压性能,成为通用稳压场景的高性价比选择,可满足消费电子、工业控制等多领域的实际需求。

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.
