RUILON 1.5KE30CA 瞬态抑制二极管(TVS)产品概述

一、产品基本信息

1.5KE30CA是RUILON(瑞隆源)品牌推出的一款双向瞬态抑制二极管(TVS),属于过压保护器件核心品类。其核心作用是快速响应电路中的瞬态过压(如雷击浪涌、开关浪涌、静电放电等),通过将过压钳位至安全范围,保护后端敏感电子元器件免受损坏。

该器件采用DO-201AD轴向引线封装,是工业级、消费电子领域常见的过压保护解决方案之一,适配多种PCB布局场景。

二、核心电性能参数详解

1.5KE30CA的关键参数针对24V级电路优化,核心参数及意义如下:

1. 极性与工作电压范围

  • 极性:双向:无需区分正负极,无论电路中出现正向还是反向过压,均能快速导通保护,适合双向信号/电源线路(如RS485总线、24V直流电源)。
  • 反向截止电压(Vrwm):25.6V:正常工作时允许的最高反向电压,电压未超过此值时,器件处于高阻态,不影响电路正常运行。
  • 击穿电压(Vbr):31.5V:器件从高阻态转为低阻态的典型导通电压,此时开始主动吸收瞬态能量。

2. 过压保护能力

  • 钳位电压(Vc):41.4V:在峰值脉冲电流(Ipp)作用下,器件两端能维持的最高安全电压——这是保护的核心指标,确保被保护器件(如MCU、传感器)的电压不超过其损坏阈值。
  • 峰值脉冲电流(Ipp):36A(10/1000μs脉冲):器件能承受的最大瞬态脉冲电流,“10/1000μs”是国际通用的浪涌脉冲波形参数(前沿10μs、半峰值持续1000μs)。
  • 峰值脉冲功率(Ppp):1.5kW(10/1000μs脉冲):器件可吸收的最大瞬态功率,约等于钳位电压与峰值电流的乘积(41.4V×36A≈1490W,与标称值一致),能应对强浪涌冲击。

3. 正常工作损耗

  • 反向漏电流(Ir):1μA:在反向截止电压下的漏电流极小,几乎不增加电路功耗,不影响系统正常工作。

三、封装与物理特性

1.5KE30CA采用DO-201AD轴向封装,具体物理特性(参考行业标准):

  • 封装尺寸:直径φ5.0mm,长度≈10.5mm,引线直径φ0.8mm;
  • 耐温范围:工作温度-55℃~+150℃,符合工业级环境要求;
  • 焊接兼容性:支持通孔焊接,适配波峰焊、手工焊等工艺,批量生产效率高。

该封装可靠性强,抗振动、抗冲击性能优异,适合 harsh 环境下的应用。

四、典型应用场景

1.5KE30CA的参数特性使其适配多类24V级电路的过压保护:

1. 直流电源线路保护

  • 24V工业电源、LED驱动电源、充电器等,防止开关切换浪涌、电网雷击过压损坏后端器件。

2. 通信接口保护

  • RS485总线、CAN总线、以太网接口等双向信号线路,解决总线通信中的静电放电(ESD)、浪涌干扰问题。

3. 工业控制电路

  • PLC模块、传感器节点、伺服驱动器等设备的电源/信号端口,抵抗工业现场的电磁干扰(EMI)和瞬态浪涌。

4. 汽车电子(扩展应用)

  • 12V/24V汽车辅助电路(如车载充电器、传感器),应对汽车点火浪涌、静电干扰。

五、产品优势与特点

  1. 双向保护简化设计:无需区分正负极,降低电路布局复杂度,减少安装错误风险;
  2. 高功率吸收能力:1.5kW峰值功率可应对强浪涌,保护效果优于普通TVS器件;
  3. 低钳位电压保障安全:41.4V钳位电压远低于常见器件(如MCU耐压50V+)的损坏阈值,保护可靠性高;
  4. 小漏电流低功耗:1μA漏电流不影响电路正常工作,适合低功耗系统;
  5. 成熟封装高可靠性:DO-201AD封装经市场验证,抗恶劣环境能力强,性价比高。

1.5KE30CA作为一款高性价比双向TVS,是24V级电路过压保护的主流选择,广泛应用于工业、通信、消费电子等领域。

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.
