BZT52C18S 是一颗独立式低功耗稳压二极管(齐纳二极管),额定稳压值为 18V(名义值),实际稳压范围为 16.8V 至 19.1V。该器件由 MDD 品牌提供,采用小型表面贴装封装 SOD-323,适用于空间受限和低功耗电源稳压或过压保护场合。器件在 13V 反向偏压下反向漏电流极小(100nA),动态阻抗较高(Zzt = 45Ω),最大耗散功率为 200mW。
BZT52C18S 在反向击穿区工作以提供接近恒定的电压输出。常见应用包括:
总结:BZT52C18S 是一款适用于小电流、空间受限场合的 18V 稳压二极管,特点为低漏电、SOD-323 小封装与 200 mW 的耗散能力。设计时应关注功耗、动态阻抗对稳压精度的影响,并合理选择工作电流与 PCB 热管理方案,以保证长期可靠运行。

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.
