P6KE15CA 产品概述

一、产品简介

P6KE15CA 是一款双向瞬态电压抑制器(TVS),由 RUILON(瑞隆源)提供,采用 DO-15 轴向通孔封装。器件专为钳位和吸收瞬态过电压(如雷击、开关感应、静电放电等)而设计,工作温度范围宽(-55℃ 至 +150℃),适用于工业级及汽车级苛刻环境下的浪涌保护需求。

二、主要参数

  • 类型:双向 TVS(二向对称钳位)
  • 钳位电压(Vc,典型):21.2 V
  • 击穿电压(Vz,典型):15.8 V
  • 反向截止电压 Vrwm(稳压工作电压):12.8 V(即常态工作电压上限)
  • 峰值脉冲功率 Ppp:600 W @ 10/1000 μs 波形
  • 峰值脉冲电流 Ipp:28 A @ 10/1000 μs
  • 反向泄漏电流 Ir:1 μA(在 Vrwm 条件下的典型量级)
  • 极性:双向(Bi-directional)
  • 封装:DO-15(轴向通孔)
  • 工作温度:-55℃ ~ +150℃

三、器件特点与行为

  • 双向结构能在正负瞬态两方向上对电压进行对称钳位,适合交流或可能出现正反极性瞬态的电路。
  • Vrwm = 12.8 V 表示器件可在不触发击穿的情况下长期承受约 12.8 V 的直流或峰值电压,常用于 12V 供电总线的浪涌保护。
  • 在规定脉冲测试条件(10/1000 μs)下,器件能承受 600 W 的瞬态功率,峰值电流约 28 A,钳位电压约 21.2 V,从而将危险瞬态限制在安全范围内,保护后端元件。
  • 低泄漏电流(约 1 μA)有利于不影响正常电路静态性能。

四、典型应用

  • 12V 汽车总线防护(防浪涌、负载掉电瞬态)
  • 工业电源与控制系统的输入/输出接口浪涌保护
  • 通信与基站设备的过压与感应浪涌抑制
  • 电机驱动、电源模块、继电器驱动端的过压防护

五、安装与使用建议

  • DO-15 轴向通孔封装适合插件安装,便于手工或自动化装配。安装时注意保持良好焊接,以保证散热与机械可靠性。
  • 波形能量与脉冲电流应在器件额定值范围内;超出 Ppp 或 Ipp 可能导致器件损坏。对重复脉冲或高能量环境,应考虑并联更高能量的保护或配合熔断器/限流元件。
  • 在靠近受保护器件处布局能提高保护效果,尽量缩短 PCB 走线并避免环路面积过大,以降低感应耦合。
  • 对长期直流工况,应确保工作电压低于 Vrwm,以避免持续进入雪崩而导致自热和漏电上升。

六、选型与注意事项

  • 选择时关注 Vrwm 与系统最大工作电压匹配;P6KE15CA 的 Vrwm ≈12.8V,适合 12V 类系统,但不宜用于较高直流母线。
  • 若系统可能遭受更高能量冲击,考虑能承受更高 Pppm 或采用多级保护策略(串联阻抗 + TVS + 熔断保护)。
  • 双向器件不能用于需要单向导通的 DC 阻断场合(例如做整流后的直流稳压单向保护应选择单向 TVS)。
  • 注意静电防护和存储环境,避免在装配和操作时损伤器件。

七、总结

P6KE15CA(RUILON,DO-15)是一款适用于 12V 级系统的双向 TVS 器件,具有 600 W 峰值脉冲吸收能力、21.2 V 典型钳位和宽温范围,适合工业与汽车等需要可靠瞬态保护的应用场景。合理的电路布局与能量评估能显著提升保护效果与系统可靠性。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
