LM3Z2V0T1G 是 LRC(乐山无线电)推出的一款独立式稳压二极管,标称稳压值 2.0V,实际稳压范围 1.91V ~ 2.09V。该器件采用 SOD-323 小型表贴封装,额定耗散功率 200mW,工作结温范围宽 (-65℃ ~ +150℃),适合空间受限且对低电压基准或保护有要求的便携产品与消费电子设备。
注:Zzk、Zzt 为厂家给出的阻抗指标,用于表征稳压二极管在不同测试条件下的小信号阻抗特性,设计时应参考厂家完整规格书以确定测试条件。
SOD-323 为常见的小型表贴封装,适合自动贴装与回流焊工艺。封装体积小、引脚短,有利于寄生电感与电阻控制;但热阻相对较高,长时间大电流工作需重点考虑 PCB 热扩散设计。器件工作温度范围达到 -65℃ ~ +150℃,适合工业与严苛温区应用。
如需更高功率或更低动态阻抗,可考虑功率更高的稳压二极管或采用有源基准芯片;若空间允许且需更高精度与温度稳定性,可选低温漂基准源。选型时注意比较稳压值容差、阻抗、最大耗散与封装热阻等关键参数。
LM3Z2V0T1G 是一款面向低压基准、钳位与小功率保护场合的独立式 2V 稳压二极管,凭借 SOD-323 小封装与宽工作温度,适合便携与工业级电路。设计时应关注工作电流、功耗与热管理,结合厂方完整规格书与热降额信息完成可靠性评估与 PCB 布局。

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.
