5.0SMDJ33CA 产品概述
一、产品简介
5.0SMDJ33CA 是 DOWO（东沃）出品的一款高能量瞬态电压抑制二极管（TVS），封装为 SMC（DO-214AB），双向极性，专为保护直流或交流电路免受雷击、开关感应和电磁脉冲等瞬态过压损害而设计。该器件在 10/1000µs 波形条件下具有 5kW 峰值脉冲功率能力，适用于工业级和商用防护场合。
二、主要电气参数
- 反向截止电压 Vrwm：33V（双向）
- 钳位电压 Vc：53.3V（Ipp=93.8A 时）
- 峰值脉冲电流 Ipp：93.8A（10/1000µs）
- 峰值脉冲功率 Ppp：5kW @10/1000µs
- 击穿电压 Vbr：36.7V
- 反向漏电流 Ir：≤5µA
- 工作温度范围：-55℃ ~ +150℃
三、产品特点
- 高能量吸收：5kW@10/1000µs，能承受强脉冲冲击。
- 快速响应：纳秒级响应，有效钳位瞬态电压。
- 低漏电流：5µA 典型值，适合对静态功耗敏感的系统。
- 宽温区可靠性：-55℃ 至 +150℃ 满足严苛环境需求。
- 标准化封装：SMC（DO-214AB）便于自动化贴装与散热处理。
四、典型应用场景
- 电源线路与分配系统过压保护（DC/AC）。
- 通信基站、监控设备与工业控制器的防雷与浪涌保护。
- 汽车电子模块（建议核对汽车级规范），电池管理与充电设备。
- 配电箱、逆变器、变频器等高能场合的局部浪涌防护。
五、安装与使用建议
- 建议尽量靠近被保护的元件或电源入口处布置，以缩短走线感应。
- 采用合适的焊接工艺，遵循封装的焊接温度曲线以保证可靠性。
- 对于重复闪络或频繁过压场合，评估热耗散及可能需并联/串联使用的方案。
- 设计时考虑 PCB 铜箔面积与散热路径，必要时增加散热铜皮。
六、选型与注意事项
在选用时请核对系统工作电压与 Vrwm、钳位电压要求，确认在最大脉冲条件下钳位电压对下游器件的安全性。对于特殊环境或更严格汽车级、航空级要求，请咨询厂商提供完整可靠性与认证资料。
如需样品、封装尺寸图或更详细的电气曲线，请提供具体需求以便进一步支持。

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.
