SMCJ36A (DOWO 东沃) TVS 瞬态抑制二极管 产品概述
一、产品简介
SMCJ36A 是 DOWO（东沃）推出的一款玻璃钝化芯片 TVS（瞬态电压抑制）二极管，封装为 SMC (DO-214AB)。该器件提供单向（也可选双向）保护，针对雷击、浪涌和静电放电（ESD）等瞬态过压事件提供高速响应与高能量吸收能力。
二、主要参数
- 反向截止电压（Vrwm）：36 V
- 击穿电压（VBR）：40 V
- 钳位电压（Vc，Ipp）：58.1 V
- 峰值脉冲电流（Ipp）：36 A
- 峰值脉冲功率（Ppp）：1500 W（测试波形 10/1000 μs，重复率/占空比 0.01%）
- 反向电流（Ir）：1 μA（常温）
- 工作温度范围：-55 ℃ ～ +150 ℃
- ESD 防护：符合 IEC 61000-4-2，空气放电 15 kV，接触放电 8 kV
- 封装：SMC (DO-214AB)，玻璃钝化芯片，RoHS 合规
三、特性与优势
- 高能量吸收：1500 W/10/1000 μs 的脉冲功率能力，可应对工业级雷击和浪涌事件。
- 低钳位电压：58.1 V 的钳位水平，在限制过压幅度方面表现优良，有效保护下游元件。
- 极低漏电流：1 μA 级，适合对静态功耗敏感的电路。
- 快速响应：典型 TVS 响应时间可在纳秒级，有效钳制 ESD 与快速瞬态。
- 工业级温度范围和可靠性：-55 ℃ 至 +150 ℃，适用环境广泛。
四、典型应用
- 电源输入端、DC 总线、汽车电子、工业控制系统的浪涌保护
- 通信设备、基站、电源模块、逆变器输入/输出保护
- PCB 上作为沿地线或电源线的并联保护器件以防雷击与 ESD
五、安装与选型建议
- 选型时确保 Vrwm 高于最高工作电压并留有安全裕量；若系统存在反向瞬态，考虑双向版本。
- 注意钳位电压与被保护器件的耐压上限，确保 Ipp 条件下 Vc 不超过被保护元件极限。
- PCB 布局应缩短保护二极管到被保护端的走线，提供良好散热路径并参考 SMC 封装的焊盘尺寸。
- 遵循制造商的回流焊工艺建议，避免长时间高温引起封装或芯片应力。
六、合规与可靠性
- 采用玻璃钝化芯片工艺，提高长期稳定性与击穿可重复性。
- 满足 RoHS 要求，且通过 IEC-61000-4-2 的 ESD 测试（15 kV 空气、8 kV 接触），适合需要高等级静电防护的场合。

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.
