P6KE250CA/B 概述
一、产品简介
P6KE250CA/B 为 Brightking（台湾君耀）生产的双向瞬态电压抑制（TVS）二极管，玻璃钝化结结构，封装为 DO-204AC (DO-15)。器件专为抑制瞬态浪涌与脉冲过压设计，在 10/1000 μs 波形下具有 600W 峰值脉冲功率能力（重复率/占空比 0.01%），适用于 I/O 接口与 AC/DC 电源保护等场合。
二、主要电气参数
- 极性：双向
- 反向截止电压 (Vrwm)：214 V
- 击穿电压 (VBR)：237 V
- 钳位电压：344 V（典型）
- 峰值脉冲电流 (Ipp)：1.8 A（10/1000 μs）
- 峰值脉冲功率 (Ppp)：600 W（10/1000 μs，重复率 0.01%）
- 反向电流 (IR)：1 μA（给定条件下）
三、关键特性与优势
- 玻璃钝化结：提高可靠性与长期稳定性，适合恶劣环境应用。
- 低齐纳阻抗：在浪涌事件中能提供更低的钳位电压，降低受保护电路的应力。
- 快速响应：对纳秒至微秒级的瞬态电压抑制响应迅速，保护敏感电子元件。
- 高能量吸收能力：600W（10/1000 μs）峰值能力，适合偶发的强脉冲浪涌。
四、典型应用场景
- 工业和消费类 I/O 接口（串口、并口、信号线接口等）防护
- AC/DC 电源输入端瞬态抑制（交流侧或直流侧双向保护）
- 电机驱动、照明、电源适配器和逆变器等系统的局部过压防护
- 需要双向浪涌保护的通信与控制线路
五、设计与使用建议
- 浪涌容量依赖波形与占空比：Ppp 标称基于 10/1000 μs、0.01% 重复率；频繁或长脉冲可能导致器件发热或损坏，应按实际工况降额使用。
- 热管理：DO-204AC 轴向封装热阻相对较大，尽量缩短导线、改善散热路径或在 PCB 设计中增加热大地/散热结构。
- 极性确认：作为双向 TVS，无需区分正负极，安装时注意机械稳固与焊接工艺。
- 选型匹配：Vrwm 与系统工作电压应有足够余量，确保平时不进入击穿区而在浪涌时有效钳位。
如需器件详细曲线、封装尺寸或可靠性数据（冲击、温度循环等），可根据型号 P6KE250CA 或 P6KE250CB 向 Brightking 获取完整规格书与测试报告。

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.
