1.5KE62CA瞬态抑制二极管(TVS)产品概述

一、产品基本属性与核心定位

1.5KE62CA是东沃(DOWO)品牌推出的轴向引线型瞬态抑制二极管(TVS),采用DO-201AD封装,属于双向极性防护器件。该产品专为电路系统的瞬态过压防护设计,可快速响应浪涌冲击(如雷击、电源波动、电机启停),将过压钳位至安全范围,避免后级敏感元件(IC、传感器、功率器件等)损坏,广泛适配工业、汽车、通信等多领域场景。

二、关键电气参数与性能解读

TVS的核心性能由电气参数直接支撑,1.5KE62CA的关键参数及实际意义如下:

  • 反向截止电压(Vₘₙ):53V
    指器件正常工作时(无过压)可承受的最大反向电压,需匹配电路正常工作电压(建议电路电压≤50V以留安全余量);
  • 击穿电压(V_BR):最小58.9V
    器件开始导通的最低电压,确保过压时快速响应,避免延迟导致元件损坏;
  • 钳位电压(V_C):85V
    过压冲击时器件将电压钳位至该值,需小于后级器件的最大耐压(如后级IC耐压≥90V则安全);
  • 峰值脉冲电流(I_PP):17.65A
    1.5kW脉冲功率下的最大允许峰值电流,反映器件抗浪涌能力;
  • 峰值脉冲功率(P_PP):1.5kW(10/1000μs波形)
    标准10/1000μs浪涌波形下的最大承受功率,可应对强瞬态冲击(如电网浪涌);
  • 反向漏电流(I_R):1μA
    正常工作时反向漏电流极低,不影响电路正常功耗与精度;
  • 工作温度范围:-55℃~+150℃
    覆盖极端工业环境(户外设备、汽车发动机舱)的温度需求,无性能衰减。

三、封装特性与物理可靠性

1.5KE62CA采用DO-201AD轴向引线封装,具有以下实用特点:

  • 安装便捷:轴向引线适配通孔PCB焊接,引脚间距符合工业标准,无需特殊工装;
  • 耐环境性:环氧树脂封装材料耐高温(焊接温度≤260℃)、抗机械振动,符合工业级可靠性要求;
  • 尺寸紧凑:典型尺寸(直径≈5mm,长度≈10mm),适合空间受限的电路设计(如车载ECU)。

四、典型应用场景

结合参数与封装特性,1.5KE62CA适用于以下核心场景:

  1. 工业自动化:PLC、伺服驱动器、传感器模块的过压防护,应对电机启停、电网浪涌;
  2. 汽车电子:车载ECU、胎压监测、摄像头模块的瞬态防护(温度范围适配汽车高温环境);
  3. 通信设备:基站收发器、路由器、光纤接口的浪涌抑制,防止雷击或电源波动损坏;
  4. 电源系统:开关电源、UPS、电池管理系统(BMS)的输出端防护,保护电池与负载;
  5. 医疗电子:监护仪、输液泵等设备的接口防护,低漏电流不影响医疗设备精度。

五、产品优势与选型建议

5.1 核心优势

  • 双向防护:无需区分正负极,简化安装流程,同时实现正负过压防护;
  • 宽温稳定:-55~150℃温度范围,可在极端环境下长期可靠工作;
  • 高抗浪涌:1.5kW脉冲功率+17.65A峰值电流,应对常见强浪涌冲击;
  • 低功耗设计:1μA漏电流,正常工作时几乎不消耗额外功率;
  • 快速响应:ns级响应时间,瞬间钳位过压,保护速度远超压敏电阻。

5.2 选型注意事项

  • 需确保Vₘₙ≥电路正常工作电压(如电路48V工作,Vₘₙ53V完全匹配);
  • 钳位电压V_C≤后级器件最大耐压(如后级IC耐压100V,V_C85V安全);
  • 若需更大脉冲功率,可多个器件并联使用(需保证均流,建议间距≥2mm)。

六、总结

1.5KE62CA作为东沃品牌的工业级TVS器件,以双向极性、宽温范围、高抗浪涌能力为核心优势,适配多领域电路的瞬态过压防护需求。其DO-201AD封装安装便捷,低漏电流设计不影响电路性能,是工业自动化、汽车电子、通信设备等场景中替代传统防护器件的可靠选择。

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.
