P6KE10CA（双向TVS瞬态抑制二极管）产品概述
P6KE10CA是DOWO（东沃） 推出的一款双向瞬态抑制二极管（TVS），采用经典DO-204AC（DO-15）轴向插件封装，专为电子设备的瞬态过压防护设计，可有效抑制静电放电（ESD）、雷击感应浪涌、电源开关瞬态等异常高压，保护后端敏感元器件（如MCU、传感器、通信芯片）免受损坏。产品兼顾高防护能力与小体积，广泛适配消费电子、工业控制、通信设备等多领域应用。
一、产品核心定位与典型应用场景
P6KE10CA的核心定位是低成本、高可靠性的通用型双向过压保护器件，无需区分正负极即可实现双向防护，适合对防护极性无明确要求的电路场景。典型应用包括：
- 消费电子：手机、平板、智能穿戴的充电端口、耳机接口防护；
- 通信设备：路由器、交换机的以太网端口、RS485/RS232接口防护；
- 工业控制：PLC I/O端口、传感器接口的浪涌防护；
- 电源系统：5V/12V小型电源模块的输入/输出端防护。
二、关键电气参数详解
P6KE10CA的核心参数明确防护边界，关键参数及意义如下：
参数名称 数值 应用意义 极性 双向 无需区分正负极，简化电路设计，适配双向信号/电源防护 反向截止电压（Vrwm） 8.6V 正常工作时可承受的最大反向电压，不导通，不影响信号传输 击穿电压（Vbr） 9.5V 瞬态过压超此值时，TVS开始导通，进入防护状态 钳位电压（Vc） 14.5V 峰值脉冲下TVS两端最大电压，需低于后端元件耐压极限（如15V以上） 峰值脉冲电流（Ipp） 41.38A 10/1000us浪涌波形下的最大可承受电流，反映防护能力 峰值脉冲功率（Ppp） 600W@10/1000us 10/1000us浪涌波形下的最大防护功率，适配中等强度浪涌场景 反向漏电流（Ir） 10uA 截止状态漏电流极小，不影响电路正常功耗注：10/1000us波形是国际通用浪涌测试标准（上升10μs、半峰值1000μs），对应实际雷击感应浪涌。
三、封装与可靠性设计
P6KE10CA采用DO-204AC（DO-15）轴向插件封装，具备以下优势：
- 体积小巧：尺寸约φ2.7mm×5.2mm，可集成到紧凑PCB设计中；
- 散热可靠：轴向引线便于焊接，焊盘面积满足600W脉冲散热需求；
- 宽温适配：工作温度范围-55℃~+150℃，通过高温老化、温度循环测试；
- 环保合规：符合RoHS无铅标准，无有害物质释放。
四、典型应用电路参考
以5V电源端口防护为例，电路设计如下：
- 结构：P6KE10CA并联在5V正极与GND之间（双向无需极性），前端串联自恢复保险丝（PPTC）；
- 原理：
- 正常工作：TVS截止，漏电流10uA，不影响5V供电；
- 过压触发：浪涌电压超9.5V时，TVS瞬间导通，钳位电压至14.5V以下，保护后端芯片；
- 恢复正常：过压消失后，TVS自动截止，电路恢复。
另可用于RS485差分接口：两个P6KE10CA分别并联A线-GND、B线-GND，实现双向信号防护。
五、选型与使用注意事项
为确保防护效果，需注意：
- 电压匹配：Vrwm≥电路正常电压（如5V选8.6V满足），Vc≤后端元件耐压；
- 功率匹配：Ppp≥电路最大浪涌功率（如≤500W适配）；
- 并联扩容：需更大电流时，可多器件并联（注意均流）；
- 散热优化：频繁浪涌场景需增大焊盘面积，预留散热空间；
- 极性确认：双向器件无需区分正负极，直接并联被保护端口。
P6KE10CA凭借双向防护、高功率密度、小体积等优势，成为电子设备过压防护的高性价比选择，适配多领域防护需求。

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.
