DOWO 5KP64A 产品概述
一、产品简介
DOWO（东沃）5KP64A 是一款高能量吸收能力的瞬态电压抑制器（TVS），采用玻璃钝化芯片工艺与轴向（Axial）封装设计。该器件为单向结构，反向截止电压（Vrwm）为 64V，具有 5000 W 峰值脉冲功率能力（脉冲波形 10/1000 μs，重复率/占空比 0.01%），专为工业、电源与通讯等场合的浪涌抑制与过压保护设计。
二、主要电气参数
- 极性：单向（亦提供双向型号可选）
- 反向持续工作电压 Vrwm：64 V
- 击穿电压 VBR（指定电流下）：71.1 V
- 钳位电压 Vc（峰值脉冲时）：103 V
- 峰值脉冲电流 Ipp：48.54 A（对应 10/1000 μs，Ppp=5 kW）
- 峰值脉冲功率 Ppp：5000 W（10/1000 μs）
- 反向漏电流 Ir：2 μA（常温、在 Vrwm 下）
- 工作温度范围：-55 ℃ ～ +150 ℃
三、关键特性
- 玻璃钝化芯片：提高器件稳定性、耐候性与长期可靠性。
- 高能量吸收：5 kW（10/1000 μs）脉冲能力，能有效吸收雷击、开关切换和其他长脉冲能量。
- 低泄漏电流：在正常工作电压下漏电小，有利于降低静态功耗与温升。
- 优秀钳位性能：在高脉冲电流通过时仍能将电压限制在可接受范围，保护后端电路。
- 响应迅速：能在瞬态到来时快速触发夹止，减少器件和系统受损风险。
- RoHS 合规：符合环保要求，适用于多种行业设备。
四、典型应用场景
- 通信与基站电源保护（直流 48V/60V 系统）。
- 工业控制设备与配电柜的输入端浪涌保护。
- 不间断电源（UPS）、逆变器与储能系统的过压防护。
- 电源模块、伺服驱动器及继电器回路的浪涌抑制。
- 其他需要高能量吸收、长脉冲抑制的电路保护场合。
五、封装与安装建议
- 封装形式：轴向引线封装（Axial），便于通过孔插件安装与更换，适合波峰焊或手工焊接。
- 布局建议：将 TVS 靠近被保护端口或电源输入端放置，短、粗的接地线或回流路径可降低接地感抗，提高保护效率。
- 并联/串联：如需更高功率或更低钳位，可按制造商指导进行并联/串联设计并注意电流分配与热管理。
六、可靠性与使用注意
- 操作环境温度为 -55 ℃ 至 +150 ℃，在高温环境下应注意热量散逸与周围元件热兼容性。
- 虽为高能器件，但连续或频繁的大能量冲击会缩短寿命，建议配合熔断器或限流措施使用以提升整体保护可靠性。
- 选型时若系统有双向浪涌或交流方向性要求，可选用对应的双向型号。
5KP64A 以其高能量吸收能力、低泄漏与出色的钳位特性，适合在需要可靠浪涌保护的工业与电源系统中作为第一道防线。购买与应用时建议参考 DOWO 提供的完整数据手册和应用说明，以确保参数匹配与装配可靠。

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.
