SMAJ36A（MDD）TVS 二极管产品概述
一、产品概述
SMAJ36A 是 MDD 提供的一款单向瞬态电压抑制（TVS）二极管，封装为 SMA（DO-214AC）。器件设计用于在高能脉冲冲击或雷击浪涌情况下快速钳位电压，保护敏感电子元件免受过压损害，典型工作领域包括汽车电子、工业控制、通信设备和电源输入端等。
二、主要参数
- 钳位电压（Vc）：58.1 V
- 击穿电压（Vbr）：44.2 V
- 反向截止电压（Vrwm）：36 V
- 峰值脉冲功率（Ppp）：400 W @ 10/1000 μs 波形
- 峰值脉冲电流（Ipp）：6.9 A @ 10/1000 μs
- 反向电流（Ir）：1 μA（在 Vrwm 条件下）
- 工作温度范围：-65 ℃ ～ +150 ℃
- 极性：单向
- 封装：SMA (DO-214AC)
- 类型：TVS 二极管
三、特点与优势
- 强力浪涌保护：400 W（10/1000 μs）能量承受能力，适合处理雷击及开关瞬变。
- 低反向泄漏：在额定工作电压下 Ir≈1 μA，有利于降低静态功耗和热积累。
- 宽工作温度：-65 ℃ 至 +150 ℃，适应苛刻环境和工业级应用。
- 小封装高可靠：SMA 封装兼顾体积与散热性能，便于表面贴装组装与自动化生产。
四、典型应用场景
- 电源输入端口（适配器、开关电源）
- 通信接口（以太网、串口、DOI 等）
- 汽车电气系统（车载电源、传感器接口）
- 工业控制与自动化设备的浪涌保护
五、使用建议与注意事项
- 推荐将 TVS 放置在被保护线与连接器或受保护元件之间的最靠近外部干扰源的位置，以最小化走线引入的串联感抗。
- 考虑脉冲重复率与热耗散，连续或高频率脉冲下要做好热设计与必要的功率降额。
- 对于高压或双向保护场景，请选择相应的双向型号；本型号为单向器件。
- 在布局上保证焊盘、散热铜箔良好连接，遵循厂方数据手册中推荐封装尺寸与焊盘布局以保证焊接可靠性。
- 了解 10/1000 μs 波形的测试条件：该参数用于雷击类脉冲能量评估，实际系统中需结合源阻抗和具体浪涌波形综合判断保护能力。
如需具体的 I-V 曲线、封装尺寸图或在特定工作点的热阻/降额曲线，可提供器件数据手册以便做更精确的设计校核。

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.
