07D220K 产品概述

一、产品简介

07D220K(品牌:RUILON/瑞隆源)为插件式压敏元件,专为低压直流/交流电路的浪涌抑制与过压保护设计。器件通过校验,适合保护12V~18V级别的电源接口与电子模块,在发生瞬态过电压时能快速钳位,保护下游元器件免受损坏。

二、主要技术参数

  • 压敏电压(Vz):20V ~ 26V
  • 钳位电压(Vc):43V(在峰值浪涌条件下)
  • 工作电压(DC):18V(最大连续直流)
  • 工作电压(AC):14V(最大连续交流)
  • 峰值浪涌电流:250A(短时脉冲)
  • 吸收能量:900mJ(单次脉冲能量)
  • 静态电容:2.8nF @ 1kHz
  • 静态功率:20mW(器件在额定工作电压下的最大耗散功率)
  • 封装形式:插件(便于波峰/手工焊接与现场更换)

三、特性与优势

  • 瞬态抑制能力强:250A峰值浪涌电流与43V钳位电压组合,可有效衰减雷击、电源浪涌或电感性开关产生的高能瞬变。
  • 能量吸收适中:900mJ的单脉冲能量,适合对短时高能脉冲的吸收与消散。
  • 适配低压系统:18V DC/14V AC连续工作电压与20~26V压敏区间,适用于12V/24V类电源保护或类似等级的电子设备。
  • 易于安装与维护:插件封装便于批量生产安装及现场替换。
  • 电容相对较大:2.8nF电容值在多数电源线上影响微弱,但对高速数据信号或高频精密线路可能产生影响,应根据电路考虑。

四、典型应用场景

  • 通用电源输入端保护(开关电源、适配器、充电器)
  • 汽车电子低压系统、车载辅助电源保护(需确认工作温度和汽车认证)
  • 工业控制器、PLC 等低压电源浪涌防护
  • 电池管理与逆变器的外围保护模块

五、使用与注意事项

  • 在选型时确认系统最大连续电压不超过器件工作电压(DC18V/AC14V)。
  • 对于对信号完整性要求高的接口(USB、以太网、高清视频线),建议使用低电容保护器件以免影响传输。
  • 针对反复高能脉冲应用,应评估器件的循环寿命与散热,必要时并联多个元件或采用更高能量规格。
  • 静态功率20mW对应的泄漏电流约为20mW/18V ≈ 1.1mA,用于估算待机功耗影响。

六、封装与选型建议

插件封装便于检修与替换,适用于维修友好型设计。选择时应综合考虑压敏电压范围与系统工作电压余量、钳位电压与被保护器件耐压、能量与浪涌电流水平以及电容对电路的影响。

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
