SZA8.2A稳压二极管产品概述

SZA8.2A是乐山无线电(LRC)推出的一款表面贴装稳压二极管,采用DO-214AC(SMA)封装,标称稳压值为8.2V,最大耗散功率1W,具备低漏电流、宽结温范围等特性,适用于多种中低功率稳压、基准电压参考及简单过压保护场景,是小型化电子电路中常用的基础稳压元件。

一、核心性能参数详解

该款稳压管的核心参数围绕稳压特性、功耗、阻抗及环境适应性展开,具体如下:

  1. 稳压值:标称值为8.2V,允许范围为7.79V~8.61V(对应±5%精度),覆盖大多数基础稳压需求,无需额外校准即可满足一般应用;
  2. 反向电流(Ir):典型值仅500nA,远低于常规稳压管漏电流水平,反向截止状态下功耗极低,适合低功耗系统设计;
  3. 耗散功率(Pd):最大1W,可支持中等功率的稳压应用(如小型电源模块的辅助输出),避免功率过载损坏;
  4. 阻抗特性:包含两种关键阻抗——动态阻抗(Zzt)5.5Ω(工作电流下)和低电流阻抗(Zzk)1.3kΩ,低动态阻抗确保电流变化时稳压输出波动小,性能稳定;
  5. 工作结温范围:-50℃~+150℃,覆盖极宽温度区间,可适应户外低温(如北方冬季设备)、高温(如功率器件周边)等极端场景。

二、封装与品牌背景

  1. 封装形式:DO-214AC(SMA)为表面贴装封装,体积小巧(尺寸约2.3mm×3.0mm×1.0mm),无需插件焊接,适配自动化贴装产线,同时节省PCB空间,适合便携式设备、小型电源等高密度电路;
  2. 品牌保障:乐山无线电(LRC)是国内知名半导体厂商,拥有数十年分立器件研发生产经验,产品在可靠性、一致性方面经过市场验证,SZA8.2A的封装工艺成熟,焊接可靠性高,长期工作稳定性好。

三、典型应用场景

结合参数特性,SZA8.2A的典型应用包括:

  1. 小型电源稳压:用于5V/12V电源模块的辅助输出稳压(如单片机、传感器供电);
  2. 低功耗基准参考:作为物联网节点、便携式仪表的电压基准,低漏电流不影响系统整体功耗;
  3. 信号调理电路:为温度/压力传感器的放大电路提供稳定偏置电压,低阻抗确保偏置波动小;
  4. 简单过压保护:配合限流电阻组成过压钳位电路,防止通信接口、电源输入端因瞬时过压损坏;
  5. 宽温环境应用:适应-50℃~+150℃,可用于户外工业设备、车载电子边缘电路(需结合具体场景验证汽车级要求)。

四、关键特性与优势

SZA8.2A的核心优势体现在:

  1. 精度稳定:±5%稳压精度+5.5Ω动态阻抗,输出电压波动小;
  2. 低功耗设计:500nA漏电流使待机/截止状态几乎无额外功耗,适合电池供电设备;
  3. 宽温适应性:极端温度下仍保持稳压性能,解决环境温度波动问题;
  4. 高性价比:LRC成熟工艺确保一致性,成本控制合理,适合批量应用;
  5. 小型化适配:SMA封装体积小、重量轻,可集成到紧凑电子设备中。

五、可靠性与环境适应性

  1. 长期稳定性:低漏电流减少内部热损耗,延缓参数漂移,延长使用寿命;
  2. 焊接可靠性:SMA封装引脚适配回流焊工艺,焊接强度高,不易虚焊;
  3. 环境耐受性:封装材料抗潮湿、抗冲击,结合宽结温范围,适合复杂应用环境。

总结

SZA8.2A是一款性能均衡、应用广泛的稳压二极管,以8.2V标称稳压、1W功率、SMA封装为核心,结合低漏电流、宽结温等特性,可满足小型电源、基准参考、过压保护等多种场景需求。乐山无线电的品牌保障及成熟工艺,进一步提升了该器件的可靠性与性价比,是电子设计中值得选择的基础稳压元件。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
