1.5KE440CA 产品概述

一、产品简介

1.5KE440CA 是 RUILON(瑞隆源)推出的一款双向瞬态电压抑制器(TVS),用于抑制高能脉冲过电压事件,保护敏感电子设备免受浪涌、电弧或感应雷击等瞬态干扰。器件封装为 DO-201AD 轴向引线形式,适合插装或波峰/回流焊接后安装在印制板或引线端子上。

二、关键电气参数

  • 极性:双向(Bidirectional),可对正负极性过压均提供保护。
  • 反向截止电压 Vrwm:376 V(最大稳态工作电压参考值)。
  • 击穿电压 VBR:462 V(器件进入限制导通的典型/封装参数)。
  • 钳位电压(Clamping Voltage):602 V(在峰值脉冲电流条件下的最大钳位电压)。
  • 峰值脉冲电流 Ipp:2.5 A @ 10/1000 μs(10/1000 µs 浪涌波形下的峰值电流能力)。
  • 峰值脉冲功率 Ppp:1.5 kW @ 10/1000 μs(短时浪涌吸收能力)。
  • 反向漏电流 Ir:1 μA(典型,额定 Vrwm 下的泄漏电流)。
  • 工作温度范围:-55 ℃ 至 +150 ℃。

三、主要特性与优势

  • 高能量吸收能力:在10/1000 μs波形下可承受1.5 kW脉冲功率与2.5 A峰值脉冲电流,适合对抗由浪涌或雷击引起的能量脉冲。
  • 双向保护:无需区分极性,适用于交流线路或可能出现反向瞬态的场合。
  • 低漏电流:在额定工作电压下泄漏电流控制在微安级,降低待保护电路的静态功耗和误动作风险。
  • 宽温度范围:适用于工业级高低温环境,可靠性好。

四、典型应用场景

  • 工业电源与电机驱动:保护直流母线、逆变器输入或控制端口免受浪涌破坏。
  • 配电与电源模块:作为配电系统、UPS 或电源滤波后的浪涌保护器件。
  • 通信与信号链路:保护高压接口、串行总线或ADC输入免受电压尖峰。
  • 建筑与户外设备:防护配电箱、充电桩或其他可能遭受雷电浪涌的设备。

五、封装与机械信息

DO-201AD 为轴向引线玻璃/金属封装,便于穿孔安装或夹装在端子之间,具有较好的机械强度和散热路径。安装时应保证良好接地与尽量短的环路引线,以优化浪涌能量传导和吸收效果。

六、选型与使用建议

  • 工作电压匹配:选择器件时保证系统正常工作电压显著低于 Vrwm,以避免长期应力导致寿命下降。
  • 浪涌能力评估:根据实际可能出现的浪涌能量与波形(如IEC标准脉冲)核算是否满足 10/1000 μs 下的 Ipp/Ppp 要求,必要时并联多只或选择更大规格TVS。
  • 散热与布局:在高能量应用中注意散热设计,确保器件在脉冲后有足够时间恢复并避免连续热累积。
  • 环境可靠性:长期在高温下工作会增加漏电流并影响寿命,需考虑温度裕度与实际工况。

七、结语

1.5KE440CA(RUILON)以其较高的浪涌吸收能力、双向保护特性和工业级温度范围,适合用于需要高压瞬态保护的电源和配电系统。在选型与布局时应结合实际浪涌规格与散热条件,确保器件发挥最佳保护效果。若需要更详细的规格图、测试条件或原厂数据表,可联系供应商获取完整资料。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
