1.5SMC36CA 产品概述

一、产品简介

1.5SMC36CA 属于 Littelfuse(美国力特)1.5SMC 系列的双向瞬态电压抑制(TVS)二极管,封装为 DO-214AB(SMC)。该器件用于对电源线路和信号线路的瞬态过电压(如雷击、电快速瞬变、静电放电等)提供钳位保护,适用于工业、通讯与电力电子等需要高能脉冲防护的场合。

二、关键参数概览

  • 钳位电压(Vc, 峰值): 49.9 V
  • 工作温度: -65 ℃ ~ +150 ℃
  • 击穿电压 (Vbr): 34.2 V
  • 反向截止电压 (Vrwm): 30.8 V
  • 峰值脉冲功率 (Ppp, 10/1000µs 或 10/1000 的典型表征): 1.5 kW
  • 峰值脉冲电流 (Ipp): 30.5 A
  • 反向电流 (Ir): 1 µA(常温, Vrwm 下)
  • 极性: 双向
  • 防护等级: 满足 IEC 61000-4-4(EFT)与 IEC 61000-4-2(ESD)

以上参数表明该器件在承受短时高能脉冲时能迅速钳位并限制过电压,同时在正常工作电压下漏电小,适合对精密电子设备进行保护。

三、主要特性与优势

  • 双向设计:适合交流线路或可能双向瞬态的场景,无需外接极性区分元件。
  • 低漏电流:Ir 仅 1 µA,有利于高阻抗或低功耗系统中减少静态功耗和误动作。
  • 宽温度范围:-65 ℃ 至 +150 ℃,可在严苛环境中长期工作,适合工业与部分汽车级应用。
  • 高抗脉冲能力:1.5 kW 峰值功率与 30.5 A 峰值电流,能有效吸收常见的浪涌与电快速瞬变能量。
  • 符合 IEC ESD/EFT 标准:提高了对静电放电与电快速瞬变的实战防护能力。

四、典型应用场景

  • 工业控制电源与总线保护(24 V / 30 V 级电源)
  • 通信设备接口与防雷前端保护
  • 测试与测量仪器的输入保护
  • 电力电子外围保护、逆变器与驱动器辅助保护电路

五、使用与选型建议

  • 反向截止电压 Vrwm 为 30.8 V,建议在系统稳态电压低于该值的电源总线上使用,以避免持续导通。
  • 在面对多次或更高能量冲击时,应通过串联阻抗、熔断器或外部能量吸收器配合使用,以防器件超过能量极限导致损坏。
  • DO-214AB 封装为表面贴装,布板时应保证良好的散热铜箔,以提高重复脉冲能力和长期可靠性;遵循厂商推荐的回流焊工艺参数。
  • 选型时若对钳位电压或脉冲能量有更严格要求,可参照 Littelfuse 全系列比较相近型号,或咨询厂家技术支持以获取更详细的脉冲曲线和应用建议。

六、结论

1.5SMC36CA 为一款面向中高能瞬态防护的双向 TVS 器件,凭借 1.5 kW 的峰值吸收能力、低漏电流与宽温度工作范围,适用于对 30 V 级电源与信号线路的稳健保护。合理的系统设计与热管理能充分发挥其防护性能,延长系统可靠性。若需进一步的脉冲波形数据、能量循环寿命或封装尺寸信息,建议参考 Littelfuse 官方数据手册或联系技术支持。

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
