PZS82C20AS_R1_00301 产品概述
一、产品简介
PZS82C20AS_R1_00301 是强茂（PANJIT）推出的一款稳压二极管，封装为 SOD-123，标称稳压值为 20V（规格范围 19V～21V）。该器件适用于对输出电压有中等精度要求的电源稳压和过压保护场合，体积小、封装标准，便于表面贴装自动化生产。
二、主要特性
- 标称稳压：20V（允许范围 19V～21V）
- 低反向电流：Ir = 100nA @ 15V，适合低漏电要求的电路
- 动态阻抗：Zzt = 48Ω（工作区），Zzk = 225Ω（拐点区），在额定测试电流下具有良好的稳压能力
- 宽工作结温：-55℃ ～ +150℃，适应温度变化大的环境
三、电气性能解读
稳压二极管的动态阻抗 Zzt 值为 48Ω，表示在规定测试电流下，器件对电压波动的抑制能力较强；Zzk = 225Ω 指示在接近击穿拐点区时的小信号阻抗，影响在低电流区的稳压特性。反向漏电仅 100nA（在 15V），使其在待机或低功耗电路中泄漏影响小。
四、封装与热特性
SOD-123 小外形适用于表面贴装，便于自动化贴装与回流焊工艺。允许的结温范围宽（-55℃～+150℃），但器件的散热能力与 PCB 布局、焊盘面积及环境条件有关，建议在实际设计中参考原厂热阻与额定功耗数据以确定安全工作范围。
五、典型应用场景
- 电源稳压模块的局部稳压或参考源
- 过压保护与浪涌钳位电路
- 仪表、通信设备和工业控制中对 20V 级别保护/稳压的场合
- 便携设备和低功耗系统（受益于低反向漏电）
六、使用注意事项
- 实际设计中请参照原厂完整数据手册确认最大功耗、测试电流条件和温度系数等参数，避免在超出热限的条件下长期工作
- 为保障散热并降低热漂，建议在 PCB 设计时加大焊盘和散热铜箔面积，避免器件长期处于高电流、高温工作点
- 在并联或串联应用时注意匹配特性，避免因动态阻抗差异引起不均流或电压偏差
七、替代与选型建议
如需更低动态阻抗或不同稳压等级，可在强茂或其他品牌的同系列稳压二极管中选择相近规格；若对漏电或温漂有更高要求，应选用专用精密参考源或具温度补偿的稳压器件。
如需我帮您整理该器件的完整参数表或推荐具体的等效替代型号，可提供更多设计背景与应用条件，我将基于实际需求给出更精确的建议。

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.
