SMAJ30CA 产品概述
一、产品概述
SMAJ30CA 是扬杰（YANGJIE）推出的一款双向瞬态电压抑制二极管（TVS），用于保护敏感电子设备免受浪涌和瞬态过电压的损害。其额定反向工作电压（Vrwm）为 30V，具备高能量吸收能力与低漏流特性，适用于工业、电源和通信类的浪涌防护场合。
二、主要电气参数
- 极性：双向（适合交流或双向浪涌抑制）
- 反向截止电压 Vrwm：30V
- 钳位电压（Clamping）：48.4V（峰值脉冲时）
- 峰值脉冲电流 Ipp：8.26A
- 峰值脉冲功率 Ppp：400W（10/1000µs 波形）
- 击穿电压 Vbr：36.8V
- 反向电流 Ir：≤5µA（在 Vrwm 下）
- 工作温度范围：-55℃ 至 +150℃
- 类型：TVS（瞬态抑制器）
- 封装：DO-214AC（SMA 封装标准）
- 品牌：YANGJIE（扬杰）
三、工作原理简介
在正常工作电压下，TVS 二极管呈高阻状态，漏电流极小（≤5µA），不会影响电路运行。当出现高于击穿电压或瞬态浪涌时，器件迅速进入导通状态，将浪涌能量钳位到安全电压（约48.4V），并通过吸收能量来保护后端元件，浪涌结束后快速恢复到高阻态。
四、关键性能与优势
- 高能量吸收：400W（10/1000µs）峰值能力，能承受较强的脉冲能量。
- 有效钳位：48.4V 钳位电压可在浪涌时将电压限制在安全范围，减少对受保护线路的冲击。
- 低反向电流：≤5µA 有助于减少静态功耗和误触发。
- 宽温度范围：-55℃~+150℃ 满足严苛环境下的可靠性需求。
- DO-214AC（SMA）封装便于表面贴装（SMT）组装与散热管理。
五、典型应用场景
适用于工业电源、逆变器输入端、直流/交流供电线路、通信设备接口、汽车电子（符合温度要求时）、消费类电源模块及任何需防护瞬态过电压的场合，尤其在需要双向浪涌抑制的交流或差分线路应用中表现优良。
六、封装与机械注意事项
DO-214AC（SMA）为常见表贴封装，便于自动贴片和回流焊。设计 PCB 时应保证器件附近有足够的散热通路和焊盘强度，同时在高能量应用中注意为器件提供良好的热沉和合适的走线，以避免长期热累积。
七、选型与使用建议
- 若电路为直流单向保护，应确认是否需要单向型 TVS；SMAJ30CA 为双向，若用于直流系统需评估极性影响。
- 确认系统最大工作电压应低于 Vrwm（30V），并且钳位电压（48.4V）满足后端元器件承受能力。
- 对于频繁或高能量浪涌场合，建议配合熔断器或限流元件共同使用以延长保护器件寿命。
- 在高温或苛刻振动环境下，遵循厂商推荐的焊接和存储规范以保持可靠性。
八、可靠性与环境适应
器件支持宽温度工作并具备较低漏电与高冲击耐受能力，能适应多种工业环境。最终应用前建议通过实际浪涌测试和环境应力测试验证整体保护方案的有效性与长期可靠性。

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.
