SMAJ130CA - 双向 TVS 二极管（SMA / MDD）
一、产品简介
SMAJ130CA 是 MDD 推出的双向瞬态电压抑制器（TVS），采用 SMA / DO-214AC 封装，专为中等能量浪涌保护设计。器件在 10/1000µs 浪涌条件下能承受显著脉冲能量，响应快、漏电流低，适用于需要双向钳位保护的电源与信号线路。
二、主要参数
- 极性：双向
- 反向截止电压 VRWM：130 V
- 击穿电压 VBR：159 V
- 钳位电压（典型）：209 V
- 峰值脉冲电流 Ipp：1.9 A @ 10/1000µs
- 峰值脉冲功率 Ppp：400 W @ 10/1000µs
- 反向电流 Ir：1 µA（典型条件）
- 工作温度：-65 ℃ ~ +150 ℃
- 封装：SMA / DO-214AC
三、工作原理与主要特性
SMAJ130CA 在正常工作电压下呈高阻、漏电流极小；当线路遭受瞬态过压（如雷击、电感开关）时，器件迅速进入雪崩导通状态，将过量能量钳位到约 209V 并通过器件泄放，从而保护后端电路。双向结构可同时抑制正、负向瞬态，适合交流或双极性信号保护。封装热阻较低，兼顾散热与封装成本。
四、典型应用场景
- 工业控制与电源输入保护（适用于工作电压≤130V 的直流或需要双向保护的场合）
- 通信与现场总线接口（如需要承受短时高能浪涌）
- 电机驱动与逆变器外围保护（用于吸收开关瞬态）
- 设备静电、雷击防护模块
五、使用与布局建议
- 贴近被保护元件布置，缩短走线长度以降低串联电感和钳位电压上升。
- 选用合适焊接工艺，遵循封装最大回流温度规范，避免热损伤。
- 在高能量应用中，注意器件热散布与散热路径，必要时辅以散热铜箔或外部阻尼元件。
- 若长期处于高温或频繁脉冲环境，应考虑器件老化和热应力对寿命的影响。
六、选型提示
选择时关注工作电压与钳位电压匹配：VRWM 130V 适合最大持续电压不超过此值的系统；钳位电压 209V 表示在浪涌状态下的残压水平，需确保后端元件能承受该电压。对于更高能量需求，可选用更大功率或并联多只器件时注意分流与热管理。
SMAJ130CA 以其低漏电、快速响应及中等能量处理能力，适合工业级防护需求，是在封装、性能与成本之间的实用选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
