LM5Z30VT1G 是一款面向表面贴装的小型稳压二极管,标称稳压值 30V,实际稳压范围 28V~32V,适合在低功率、狭小空间的电路中实现基准电压、过压钳位或低功耗分流稳压。产品由 LRC(乐山无线电)生产,封装为 SOD-523,特点是体积小、漏电低、工作温度范围宽,适用于便携设备、测量电路、保护电路等场景。
主要参数(摘要)
SOD-523 封装尺寸微小,便于高密度 PCB 布局,但热阻相对较高,因此在设计时应注意:
若需要更低的动态阻抗或更高功率能力,可考虑封装更大、Pd 更高的稳压二极管或使用专用基准源(参考 IC)。在空间受限且电流需求极低的场合,LM5Z30VT1G(SOD-523)提供了体积和性能的平衡方案。
总结:LM5Z30VT1G 适合在空间受限且电流较小的场合做 30V 级别的稳压或钳位保护,设计时重点关注功率和热管理、动态阻抗对电压稳定性的影响。

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.
