1SMA5936A 产品概述
一、概述
1SMA5936A 为独立式稳压二极管（稳压二极管/齐纳二极管），由 LGE（鲁光）生产，封装为 DO-214AC（SMA）。该器件标称稳压值为 30V，允许范围 27V～33V，耗散功率 Pd 为 1.5W，适合中低功率的电压稳压与过压钳位应用。工作结温范围宽（-55℃ 至 +150℃），适应工业级环境要求。
二、主要电气参数
- 稳压值（标称）：30V（允许范围 27V～33V）
- 反向电流 Ir：典型 1 μA（注：数据为 1 μA @ 22.8V，具体测试条件请参考完整数据手册）
- 耗散功率 Pd：1.5W（器件在良好散热条件下的最大功耗）
- 动态阻抗：Zzt ≈ 26Ω（测试点动态阻抗）；Zzk ≈ 750Ω（低电流或拐点附近阻抗）
- 工作结温范围：-55℃ ～ +150℃
- 封装：DO-214AC（SMA），适合表面贴装工艺
三、特点与优势
- 标称 30V 稳压电压，适用于需要中等电压参考或钳位的电路。
- 低反向漏电流（μA 级），在高阻抗测量或精密参考场合漏电影响小。
- DO-214AC（SMA）表贴封装，便于自动贴装与回流焊工艺，节省安装空间。
- 宽温度范围和较好的浪涌承受能力，适合工业与消费类电子应用。
四、典型应用场景
- 30V 级电源旁路与稳压参考；
- 输入过压保护与浪涌吸收（需配合限流电阻或功率控制）；
- 仪表与传感器电路中的电压基准或钳位；
- 工业控制、通信设备、汽车电子（需确认车规资格）等领域的保护与稳压模块。
五、使用建议与热管理
- 连续工作时应保证器件实际耗散功率低于 Pd 并考虑散热，建议在 PCB 上配置适当铜箔面积以降低结-环境热阻；高环境温度下按厂商温度-功率降额曲线进行降额使用。
- 为避免器件因瞬态浪涌而超出功耗能力，建议在具有较高能量的冲击路径中串联限流电阻或使用前级浪涌抑制器。
- 在设计 PCB 封装和焊盘时遵循 DO-214AC（SMA）推荐焊盘资料，确保可靠焊接与热传导。
六、选型与可靠性注意事项
- 虽然标称稳压 30V，但实际稳压值有允许范围（27V～33V），在精密参考应用中请在电路中进行标定或选择容差更小的参考源。
- 动态阻抗在不同工作电流下差异较大（Zzt 与 Zzk），在需要低噪声或低阻抗稳压时应注意工作电流选择。
- 对长期可靠性有较高要求的应用（如汽车或高可靠工业场合），建议参考完整数据手册确认封装可靠性和应力测试结果，并与供应商确认批次与出厂测试报告。
总结：1SMA5936A 是一款适用于中低功耗场合的 30V 级稳压二极管，具有低反向漏电、表贴封装和宽工作温度范围等优点。合理的电路限流与 PCB 散热设计能够保证其在实际产品中长期稳定运行。若需更详细的电气曲线、热阻和封装尺寸，请参考厂商完整数据手册或联系供应商技术支持。

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.
