EM520AG 产品概述

EM520AG 是扬杰(YANGJIE)推出的一款高压瞬态抑制二极管(TVS)型保护元件,采用 SMA-W 封装,面向需要高耐压和抗浪涌保护的电力与电子设备。该器件在元件尺寸与散热、可靠性之间取得平衡,适用于对抗雷击、开关瞬变等冲击的场景。

一、主要参数与性能亮点

  • 正向压降(Vf):2V @ 0.5A(正向导通特性,便于在反向钳位或反向保护时评估功耗)
  • 直流反向耐压(Vr):2000V(器件在反向状态下的耐压能力)
  • 整流电流(Io):500mA(允许长期通过的直流或脉冲平均电流)
  • 反向电流(Ir):≤5µA(在额定耐压下的泄漏电流,低漏电利于系统待机与灵敏电路)
  • 非重复峰值浪涌电流(Ifsm):40A(单次脉冲抗冲击能力,衡量对雷击/浪涌的缓冲能力)
  • 工作结温度范围:-55℃ 至 +150℃(宽温度适应性,适用于苛刻环境)

二、典型应用场景

EM520AG 适合用于需要高压耐受和瞬态抑制的应用,包括但不限于:

  • 高压电源输入侧的浪涌保护模块
  • 工业控制设备与变频器的过电压保护
  • 通信基站、电力线路接口的雷击/浪涌抑制
  • 医疗、电力测量仪器的输入保护(需按标准进一步验证)

三、器件特点与优势

  • 高耐压:2000V 的反向耐压使其可用于高压总线或直接承受较大反向电压的场合。
  • 低漏电:≤5µA 的小反向电流,有利于低功耗系统和精密测量前端。
  • 良好瞬态抑制能力:40A 的非重复峰值浪涌电流能有效吸收典型雷击与开关浪涌能量(具体能量吸收需结合脉冲波形评估)。
  • 宽温区:-55℃~+150℃ 的结温范围保证在极端环境下的可靠工作。

四、推荐布局与使用注意事项

  • 尽量将器件放置在被保护端口与地之间的近端,缩短导线与走线以降低串联电感,提升吸收效率。
  • 对 PCB 散热孔与焊盘进行优化,确保在浪涌事件下热量能被有效分散。SMA 封装对焊盘热阻敏感,焊接与回流需遵循厂商工艺规范。
  • 若用于重复脉冲或高能量场合,应结合外部限流或熔断保护以防器件过热失效。
  • 检查系统允许的最大允许电压和钳位电压,确认EM520AG的耐压与钳位特性满足电路要求。

五、封装与可靠性

  • 封装:SMA-W,便于表面贴装大批量自动化生产。
  • 环境可靠性:在指定结温范围内可长期工作,适配工业级环境。
  • 储存与处理:避免长时间潮湿暴露,焊接前建议按 MSL 要求回流烘烤;在装配与测试过程中注意静电防护。

六、选型建议与限制提示

  • 本器件适合以抑制高压瞬态为主的应用;若需长期频繁承受大能量脉冲,请优先评估 Ifsm 的能量承受能力与热循环寿命。
  • 对于需要特定钳位电压或更大峰值浪涌电流的系统,应参考器件完整电气特性曲线(击穿电压、钳位电压、动态电阻等)并与应用脉冲参数(如8/20µs、10/1000µs)匹配。
  • 在安全或法规敏感领域(如医疗、汽车)使用前,确认是否满足相应的认证和测试要求。

如需器件完整的 I-V 特性曲线、钳位电压数据、热阻参数或封装尺寸图,可进一步提供技术资料或咨询供应商获取官方数据手册,以便在具体设计中准确应用。

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
