1.5KE39CA 产品概述

一、产品简介

1.5KE39CA 是瑞隆源(RUILON)生产的一款双向瞬态电压抑制二极管(TVS)。该器件用于吸收和钳位瞬态过电压、电涌和浪涌能量,保护下游电子元件免受瞬态冲击损害。型号中的“1.5KE”表示单脉冲功率级别(标准10/1000 μs 波形下 1500 W),“39C”指额定工作参数,后缀“A”表示双向(bidirectional)结构,适合交流或双向脉冲保护场合。

二、关键电气参数与意义

  • 极性:双向(Bidirectional)—— 可在正负方向同时钳制,适合交流线路或无明确极性的输入端口。
  • 反向截止电压 Vrwm:33.3 V —— 在正常工作条件下(不击穿)允许的最高连续直流电压;设计时应确保电路最大工作电压低于该值。
  • 击穿电压 VBR:41 V —— 在规定测试电流下器件开始进入雪崩击穿的电压范围,表征触发点。
  • 钳位电压(在 Ipp 下):53.9 V —— 在峰值脉冲电流下器件将电压钳制到的典型值,是保护电路元件的关键参数。
  • 峰值脉冲电流 Ipp:28 A @ 10/1000 μs —— 在标准 10/1000 μs 浪涌波形下能承受的峰值电流。
  • 峰值脉冲功率 Ppp:1.5 kW @ 10/1000 μs —— 对应上述波形的瞬态吸收功率能力。
  • 反向电流 Ir:1 μA —— 在 Vrwm 下的泄漏电流,指示静态功耗与对敏感电路的影响。
  • 工作温度范围:-55 ℃ ~ +150 ℃ —— 宽温度范围适合工业级与苛刻环境。

以上参数说明该器件在 24 V 类或类似中低电压系统中具备良好的瞬态保护能力,在遭遇电涌(如雷击诱发的浪涌或开关瞬态)时能把过电压钳制在接近 54 V 的水平,从而保护下游器件。

三、封装与机械特性

  • 封装类型:DO-201(轴向引线、玻璃或环氧封装)—— 结构坚固,适合通过孔(THT)安装,便于吸热和散热。
  • 机械强度高、耐冲击能力好,适合电力、工业控制等需要较高能量吸收的场合。
  • 推荐在 PCB 上尽量缩短引线长度并靠近被保护端口安装,以降低感性回路导致的钳位过高。

四、典型应用场景

  • 24 V 工业电源输入保护、PLC、驱动器电源防护。
  • 电信/网络设备的供电线路防雷浪涌保护。
  • 电机控制、伺服放大器输入端的短时浪涌保护。
  • 太阳能逆变器的控制与辅助电源保护(需结合系统电压等级判定)。
  • 适用于需要双向保护的交流或双极性信号线路。

五、使用与选型要点

  • 确认工作电压:Vrwm 为 33.3 V,适合额定工作电压低于此值的系统。若系统稳压或瞬态可能超过此值,需改选 Vrwm 更高的型号。
  • 能量等级匹配:Ppp 1.5 kW、Ipp 28 A(10/1000 μs)说明可承受一次较大浪涌,但对于反复高能冲击或更大能量(如直接雷击)需配合熔断器、限流电阻或更高能量的 MOV 进行级联保护。
  • 钳位裕量:钳位电压 53.9 V 为典型值,设计时需确保下游元件耐压高于此钳位值,否则需选择钳位更低或采用额外抑制手段。
  • 温度与散热:工作环境高温会降低器件能量吸收能力,必要时留有热散设计或选用更大封装/散热条件的器件。
  • 安装位置:尽量靠近电源入口或外部接口端放置,减少导线感抗引起的钳位上升。

六、可靠性与测试建议

  • 建议在设计验证阶段进行 10/1000 μs 浪涌测试与 IEC/EN 浪涌标准测试,验证实际钳位电压及重复脉冲下的稳定性。
  • 对于关键设备,进行温度循环、高湿加速老化及机械振动测试,以确认封装和引线的长期可靠性。
  • 在批量采购前可索取样品并查看厂家的质量报告(如 AQL、成品出厂测试记录)。

七、储存与焊接注意事项

  • 储存:避免长期高湿、强酸碱环境;常温常湿下储存可保持性能稳定。
  • 焊接:DO-201 为轴向引线封装,使用手工或波峰焊均可;注意避免过长时间的高温暴露,遵循推荐的焊接温度与时间曲线以防封装材料受损。
  • 安装时避免过度弯折引线或强力拉伸,防止内部焊点或封装裂纹。

八、采购信息与替代建议

  • 型号:1.5KE39CA,品牌:RUILON(瑞隆源),封装:DO-201。
  • 如需替代,可寻找 1.5KE 系列中 Vrwm 接近 33 V 且为双向的同规格产品,或选用同等或更高 Ppp/Ipp 能力且钳位电压相近的 TVS 器件,注意比较 VBR、钳位电压、峰值电流与封装热耗散能力。

如需进一步提供典型钳位曲线、等效电路、封装尺寸图或与具体电路的匹配建议,可提供应用场景与电路参数,我可以根据实际情况给出更具体的设计与选型建议。

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.
