P6KE400A/B 产品概述
一、产品简介
P6KE400A/B 是 Brightking（台湾君耀）推出的一款单向高功率瞬态电压抑制器（TVS），采用玻璃钝化结工艺，专为中高电压直流系统和接口保护设计。器件响应快速、钳位能力强，能够在工业环境下有效钳制瞬态过电压，保护敏感半导体器件和电源模块免受雷击、开关瞬变等干扰。
二、主要参数与性能
- 极性：单向
- 反向待机电压（Vrwm）：342 V
- 击穿电压（VBR）：380 V（典型）
- 钳位电压：548 V（峰值钳位）
- 峰值脉冲电流（Ipp）：1.1 A（10/1000µs 波形）
- 峰值脉冲功率（Ppp）：600 W（10/1000µs，重复率/占空比 0.01%）
- 反向电流（Ir）：在12 V 以上典型小于 1 µA
- 通道数：单路
- 工作温度范围：-55 ℃ 至 +175 ℃
器件具有低齐纳阻抗，能在冲击期间维持较低的钳位电压，从而减少对被保护设备的应力；玻璃钝化结提高了长期稳定性与耐环境老化能力。典型响应时间极短，可在纳秒级别完成瞬态吸收。
三、结构与封装
封装为 DO-204AC（DO-15）玻璃封装，适合通过孔插装或波峰/回流焊接工艺的混合组装板。紧凑的体积与坚固的封装形态使其便于在PCB上靠近被保护线路布置，以减少寄生电感和提升抑制效果。
四、应用场景
- 电源端口与AC/DC电源保护（整机输入侧或次级保护）
- I/O 接口（通信口、控制信号线、传感器接口等）
- 工业控制设备、逆变器、仪器仪表的浪涌保护
- 需要高能量脉冲吸收且空间受限的场合
五、使用建议与注意事项
- 为获得最佳保护效果，应将器件尽可能靠近需要保护的输入端或连接点，减少引线长度和环路面积。
- 在高能量冲击场景下，可与系列限流元件（熔丝、电阻）或多级保护方案配合使用，以分担能量并延长寿命。
- 参考工作温度范围（-55 ℃ 至 +175 ℃）进行热设计，注意长期反复冲击会导致器件发热与性能衰减。
- 对于关键设备建议做整机级的浪涌与雷击测试，验证钳位电压与能量吸收能力满足系统要求。
P6KE400A/B 以其高能量吸收能力、低齐纳阻抗与可靠的封装工艺，适合用于对中高电压瞬态有严格保护需求的工业与电源应用，是稳健的浪涌抑制选择。

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.
