30KP400CA 产品概述
一、产品简介
30KP400CA 为 DOWO(东沃) 出品的高能量双向 TVS（瞬态电压抑制）二极管，采用玻璃钝化芯片工艺与 R-6(P600) 封装，专为工业级浪涌保护设计。其在 10/1000μs 波形下可承受高达 30000W 的峰值脉冲功率，适合对抗雷击、电源浪涌及其他短时高能瞬变。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：400 V
- 击穿电压 VBR：440 V
- 钳位电压（典型）：704 V
- 峰值脉冲电流 Ipp：42.6 A（10/1000μs）
- 峰值脉冲功率 Ppp：30 kW @ 10/1000μs，重复率（占空比）0.01%
- 反向电流 Ir：2 μA
- 工作温度：-55℃ ~ +175℃
- 类型：TVS（单向/双向单元可选）
- RoHS 符合
三、性能特点
- 玻璃钝化芯片，提升长期稳定性与可靠性。
- 极快响应时间，可在瞬态初期限制电压上升。
- 低泄漏电流（Ir≈2μA），对待保护电路影响小。
- 优异钳位能力（704V），在高能脉冲下保持受控电压。
- 高峰值功率承受能力，适合雷电与开关瞬变场景。
四、典型应用
- 电力设备与逆变器的直流/交流侧浪涌保护；
- 工业控制、PLC、变频器等设备的输入输出防护；
- 通信基站、电源模块及配电柜的雷击浪涌防护；
- 其他要求高能量吸收与快速钳位的场合。
五、封装与可靠性
R-6(P600) 封装适合波峰焊及回流工艺，散热与安装可靠。器件额定工作温度宽广（-55℃~175℃），适应恶劣工业环境。建议在实际设计中配合适当的散热路径和浪涌分流方案，以延长器件寿命并保证系统稳定。
六、选型建议与注意事项
- 若线路存在单向电压偏置，可考虑单向单元；需双向抑制则选该型号双向器件。
- 关注系统最大能量与脉冲波形，确保 Ppp 与 Ipp 能够覆盖最坏情形（建议留裕量）。
- 在高速或敏感信号线上，评估钳位电压对后级器件的冲击并配合阻抗匹配或滤波。

Send RFQ
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.
