1.5KE15CA TVS瞬态抑制二极管产品概述

1.5KE15CA是RUILON(瑞隆源)品牌推出的一款双向瞬态抑制二极管(TVS),属于1.5KE系列大功率防护器件,采用DO-201轴向封装,核心作用是抑制电路中的瞬态过压冲击,保护敏感电子元件免受雷击、静电放电(ESD)、开关浪涌等干扰损坏。

一、产品核心身份信息

  • 品牌型号:RUILON(瑞隆源)1.5KE15CA
  • 器件类型:双向瞬态抑制二极管(TVS)
  • 封装形式:DO-201(轴向引线封装,尺寸符合行业标准,便于插件安装)
  • 应用定位:中等功率电子设备的瞬态过压防护

二、关键电气参数解析

  1. 电压类参数

    • 反向截止电压(Vrwm):12.8V——电路正常工作时,TVS处于反向截止状态的最大电压,需匹配被保护电路的工作电压(如12V直流系统);
    • 击穿电压(Vbr):15.8V——反向偏置下,TVS开始击穿导通的电压,略高于Vrwm,确保正常工作时不导通;
    • 钳位电压(Vc):21.2V(10/1000us脉冲下)——浪涌冲击时,TVS能将电路电压钳位的峰值,需低于被保护器件的最大耐受电压(如25V耐压器件可安全使用)。
  2. 脉冲功率与电流

    • 峰值脉冲功率(Ppp):1.5kW(10/1000us波形)——TVS能承受的最大浪涌功率,10/1000us是行业通用浪涌波形(前沿10μs、半峰值持续1000μs);
    • 峰值脉冲电流(Ipp):71A(同波形下)——对应1.5kW功率的浪涌电流,可有效抑制中等强度的瞬态冲击。
  3. 其他电气特性

    • 反向漏电流(Ir):1μA(Vrwm下)——正常工作时的漏电流极小,不影响电路功耗;
    • 工作温度范围:-55℃~+150℃——宽温范围覆盖工业、汽车等恶劣环境,满足高低温场景需求。

三、封装与典型应用场景

  • DO-201封装特点:轴向引线设计,直径约2.5mm,长度约8.5mm,适合插件式PCB布局,安装简单且可靠性高,能承受一定的机械应力。

  • 主要应用领域:

    1. 汽车电子:12V车载电源、CAN总线接口、车灯控制电路;
    2. 工业控制:PLC输入输出模块、直流电机驱动、传感器接口;
    3. 通信设备:RS485/RS232接口、小型基站电源;
    4. 消费电子:车载充电器、户外LED显示屏电源。

    防护对象:雷击浪涌、开关切换浪涌、静电放电(ESD)、电源尖峰脉冲等。

四、性能优势与可靠性

  1. 双向防护简化设计:无需区分正负极,可直接并联在被保护电路两端,降低安装错误风险,适配正负脉冲防护需求;
  2. 快速响应瞬态干扰:TVS典型响应时间为纳秒级(ns),能瞬间抑制浪涌,避免被保护器件因过压损坏;
  3. 宽温稳定可靠:-55℃~+150℃的工作温度范围,满足工业级、汽车级环境的可靠性要求;
  4. 低功耗不影响电路:1μA的反向漏电流,对被保护电路的正常功耗无明显影响;
  5. 大功率承载能力:1.5kW峰值功率可应对中等强度的浪涌冲击,覆盖多数常规设备的防护需求。

五、选型与使用注意事项

  1. 参数匹配原则:

    • Vrwm ≥ 被保护电路的最大工作电压(如12V电路选12.8V Vrwm);
    • Vc ≤ 被保护器件的最大耐受电压(如21.2V Vc适配25V耐压器件)。
  2. 安装与焊接要求:

    • 轴向引线需预留适当长度,避免焊接应力损坏器件;
    • 焊接温度不超过260℃,焊接时间不超过10秒,防止TVS性能衰减。
  3. 并联扩容注意:若单颗功率不足,可多颗并联(双向器件无需匹配极性),但需确保所有并联器件参数一致,避免分流不均。

  4. 长期使用注意:避免电路长期处于超过Vrwm的电压下,否则会加速TVS老化,缩短使用寿命。

1.5KE15CA凭借双向防护、宽温可靠、大功率承载等特性,成为12V系统瞬态过压防护的常用器件,适用于多种工业与民用电子设备,能有效提升电路的抗干扰能力与可靠性。

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
