LM3Z9V1T1G 产品概述
一、产品简介
LM3Z9V1T1G 是 LRC（乐山无线电）出品的一款独立式稳压二极管（Zener），标称稳压值 9.1V，实际稳压范围 8.5V~9.6V。器件采用小型 SOD-323 表面贴装封装，适合体积受限的便携和消费类电子产品中作为电压基准或稳压保护元件使用。
二、主要电气参数
- 标称稳压：9.1V（Vz）
- 稳压范围：8.5V ~ 9.6V
- 反向电流（Ir）：200nA @ 50V
- 阻抗：Zzk = 160Ω（低电流测试条件），Zzt = 15Ω（高电流/规定测试条件）
- 耗散功率（Pd）：200mW
- 工作结温范围：-65℃ ~ +150℃
- 封装：SOD-323（独立式/贴片）
三、性能特点
- 小体积、低轮廓：SOD-323 适合高密度贴装应用。
- 低反向漏流：在高达 50V 时 Ir 仅 200nA，有利于低功耗电路中维持稳定偏置。
- 合理的动态阻抗：在建议工作电流下 Zzt≈15Ω，可获得较好的稳压性能；低电流下阻抗较大（Zzk≈160Ω），适用于不同负载条件的设计权衡。
- 宽温度范围和良好耐受性，适合恶劣环境工作。
四、典型应用
- 作为 9.1V 的基准/稳压源，用于电源管理、基准电路。
- 输入浪涌或尖峰电压的钳位保护。
- 传感器供电、便携设备电源参考与保护电路。
- 各类模拟与数字电路的简单稳压和电压限制。
五、设计与使用建议
- 最大稳态电流估算：Iz_max ≈ Pd / Vz = 0.2W / 9.1V ≈ 22mA。为保证可靠性建议工作电流选在 110mA 范围，典型设计可选择 28mA 以兼顾温升与稳压精度。
- 串联限流电阻计算：R = (Vin - Vz) / Iz，设计时需考虑最坏情况下的 Vin 与最大 Iz，从而保证 Pd 不被超过。
- 在低电流工作时，需注意较高的动态阻抗会影响稳压精度，可通过增大工作电流或并联滤波电容来改善瞬态响应与噪声。
六、封装与散热注意事项
SOD-323 为小功耗封装，器件自身散热受限。印制板布局应配合适量的铜箔散热区以帮助散热；若应用近 Pd 极限，应适当减小环境温度或增加铜面以降低结温。焊接工艺建议遵循表面贴装标准回流曲线，避免超时高温影响可靠性。
七、可靠性与选型要点
选型时需确认稳压范围是否满足系统容差；若电路对稳压精度要求较高，请考虑使用专用稳压芯片或精密基准源。长期可靠性取决于结温和散热条件，设计应保证在最大额定功耗下也不会导致结温超限。总体而言，LM3Z9V1T1G 以其小体积、低漏流和适中的稳压性能，适合用于空间受限且功耗要求不高的稳压与保护场合。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
