5KP22CA 产品概述
一、主要参数
- 型号：5KP22CA（品牌：DOWO/东沃）
- 类型：双向瞬态电压抑制器（TVS）
- 反向截止电压 Vrwm：22 V
- 击穿电压 Vbr（典型）：24.4 V
- 钳位电压 Vc（Ipp 条件下）：35.5 V
- 峰值脉冲电流 Ipp：148.85 A（脉冲波形 10/1000 μs）
- 峰值脉冲功率 Ppp：5 kW
- 反向电流 Ir：2 μA（在 Vrwm 条件下典型值）
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：R-6 (P600)；品牌：DOWO（东沃）
二、性能特点
- 双向结构，可同时抑制正负极性瞬态脉冲，适用于交流或可能出现极性反转的系统。
- 高能量吸收能力：Ppp 5 kW 和在 10/1000 μs 波形下近 149 A 的 Ipp，能承受工业级浪涌（如雷击感应、开关瞬变）。
- 低钳位电压（35.5 V），在 24 V 类电源或通信接口上能有效限制过压，保护后端元件免受破坏。
- 低反向泄漏（2 μA），对静态功耗影响小，适合对空载待机功耗敏感的应用。
- 宽温度范围（-55～+150 ℃），满足严苛工业和汽车电子长期可靠性需求。
三、典型应用场景
- 24 V 工业电源与现场总线保护（例如 PLC、执行器、电源模块）。
- 通信端口与接口保护（串口、以太网隔离侧、I/O 端子）。
- 电机驱动、逆变器输入端的浪涌吸收。
- 太阳能逆变、充电设备中对雷击感应与开关浪涌的抑制。
- 任何需要双向瞬态抑制且对钳位电压、能量能力有明确要求的系统。
四、设计与使用建议
- 选型时确保 Vrwm（22 V）高于正常工作电压但低于被保护电路最大承受电压，钳位电压 35.5 V 应低于后级器件的耐压极限。
- 对浪涌能量分配进行评估：10/1000 μs 波形的 Ipp 和 Ppp 是典型测试条件，实际系统可能需要结合多次脉冲和能量累积特性评估器件寿命。
- 封装与散热：R-6 (P600) 封装能承受高脉冲能量，但在频繁或高能量冲击应用中应注意 PCB 热散布局，必要时并联或采用外部限流器件分担能量。
- 安装位置建议靠近被保护端口/电源输入端，走线尽量短且回流路径良好以降低电感引起的过电压。
- 工作环境注意温度对击穿和钳位行为的影响，必要时参考厂商温度特性曲线做余量设计。
五、包装与可靠性
- R-6 (P600) 的紧凑而结实封装便于系统级布局与波峰/回流焊接（视具体封装形式而定）。
- 建议遵循厂商推荐的存储与焊接工艺，避免在极端湿度或高温条件下长期裸露。
- 在关键应用中建议与厂商确认批次试验数据与寿命曲线，以满足长期可靠性要求。
总结：5KP22CA 以其双向保护、高能量吸收与低泄漏特性，适合 24 V 级别及类似环境下的工业与通信保护应用。在设计时合理评估钳位与能量余量、优化散热与布线，可显著提升系统抗瞬态能力与长期可靠性。

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.
