1.5KE400CA 产品概述
一、产品概述
1.5KE400CA 是东沃（DOWO）推出的一款高能脉冲瞬态抑制二极管（TVS），双向工作，专为工业级过电压保护和瞬态浪涌吸收设计。器件采用玻璃钝化芯片工艺，具有快速响应、低泄漏和优异的钳位能力，能够在严苛环境下提供稳定可靠的保护。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：342 V
- 击穿电压 VBR：380 V
- 钳位电压（Ipp 对应）：548 V
- 峰值脉冲电流 Ipp：2.72 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：1500 W（10/1000 μs，重复率/占空比 0.01%）
- 反向漏电流 Ir：≤1 μA
- 工作温度范围：-55 ℃ ~ +150 ℃
- 类型：TVS 双向浪涌保护二极管
- 品牌/封装：DOWO（东沃） / DO-201AD
三、封装与机械特性
- DO-201AD 金属引线封装，适合波峰和手工焊接，便于高能量吸收场合的热管理与机械固定。
- 玻璃钝化芯片提高了器件的长期稳定性和耐湿性能，适合工业级环境。
四、核心特性与优势
- 高能量吸收：1500 W 峰值脉冲功率（10/1000 μs），能承受工业级雷击与开关冲击。
- 优秀钳位能力：在规定脉冲下钳位电压约 548 V，能有效限制被保护线路电压峰值。
- 极低漏电：Ir ≤1 μA，适合对待机功耗敏感的系统。
- 快速响应：典型 TVS 响应速度极快，可在纳秒级别抑制瞬态过电压。
- 宽温区可靠性：-55 ℃ 至 +150 ℃，适应高温、严苛工况。
- RoHS 合规：环保可回收材料，满足国际环保要求。
五、典型应用
- 工业电源与逆变器端口过压保护
- 直流配电、母线保护和电机驱动系统的浪涌抑制
- 太阳能并网逆变器、光伏系统防护
- 变电站、开关电源及大型设备的瞬态浪涌防护
六、选型与使用建议
- 确认系统工作电压与 Vrwm 匹配，1.5KE400CA 的 Vrwm=342 V 适用于更高母线或直流侧保护场景。
- 评估系统可能出现的最大脉冲能量与重复频率，保证器件在 Ppp 与占空比限制内工作。
- 在高能量冲击场合，要注意散热条件与焊接工艺，必要时配合热沉或良好接地以提高可靠性。
- 对于对称正负电压浪涌（如交流侧或双向直流回路），优先选择双向型号。
该器件结合高功率吸收能力与工业级温度性能，适合要求高可靠性与长期稳定性的电源防护与浪涌抑制应用。若需 datasheet、曲线图或样品测试建议，可联系东沃（DOWO）获取更多技术资料。

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.
