5KP440CA 是 DOWO(东沃)出品的一款双向瞬态电压抑制二极管(TVS),专为高压直流/交流电源总线和工业级脉冲浪涌保护设计。器件在短时间脉冲能量吸收能力强、工作温度范围宽、静态漏电流小,适用于需要高能量吸收且钳位电压受控的场合。
5KP440CA 采用 R-6 (P600) 封装设计,便于在布局中实现良好热路径和机械固定。封装适配高能量脉冲吸收时的热冲击和机械应力,配合合适的散热装置(散热片、金属底座或热导垫)可以提高重复浪涌能力及寿命。器件的工作温度范围宽,适用-55 ℃到 +150 ℃ 的工业和户外场景,但在高温下应考虑功率和能量的热降额。
总结:5KP440CA 以其 440 V 的工作电压、5 kW 的瞬态吸收能力与 713 V 的钳位电压,为高压电源系统和工业级浪涌防护提供了可靠的双向过压保护方案。结合合理的热管理与系统匹配,可以在多种工业与电力电子场景中发挥稳健的保护作用。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
