EM516 产品概述

一、产品简介

EM516 是 DIOTEC(德欧泰克)推出的一款高压开关二极管,单只独立器件,采用轴向 DO-41 封装。该器件直流反向耐压可达 1.8 kV,额定整流电流 1 A,非重复峰值浪涌电流 Ifsm 为 30 A,工作结温范围宽,-50 ℃ 至 +175 ℃,适合对耐压与工作温度有较高要求的高压开关与整流场合。

二、主要电气参数

  • 直流反向耐压 Vr:1.8 kV
  • 额定整流电流 IF(DC):1 A
  • 非重复峰值浪涌电流 Ifsm:30 A
  • 工作结温范围 Tj:-50 ℃ ~ +175 ℃
  • 封装:DO-41(轴向引线,二脚)
    (注:关于正向压降、反向漏电流、反向恢复时间等详细参数,请以厂家数据手册为准)

三、产品特点与优势

  • 高耐压:1.8 kV 的反向耐压使其适用于高电压传输、脉冲产生与高压电源应用。
  • 中等电流能力:1 A 的持续整流能力适配传统开关及整流用途。
  • 良好的浪涌能力:30 A 的非重复峰值浪涌电流保证在短时脉冲或启动冲击下的可靠性。
  • 宽温区工作:-50 ℃ 至 +175 ℃ 的结温范围利于恶劣环境与高温工作场合使用。
  • 标准封装:DO-41 轴向封装方便手工装配与波峰/回流焊接的引脚处理。

四、封装与标识

EM516 采用 DO-41 轴向封装,外形适合通孔安装。器件一端一般带极性标记(如环带表示阴极),便于电路板装配与极性识别。引线可根据装配需要进行适当弯曲和裁切,注意保持最小弯折半径以避免引线疲劳。

五、典型应用场景

  • 高压开关电源、脉冲高压发生器
  • 高压整流与电压倍增器(如倍压电路)
  • 离子/光电探测器的高压供电链路(需注意噪声与漏电)
  • 浪涌抑制与保护电路(短时冲击)
  • 各类需要高反向耐压的测试与实验电路

六、设计与使用建议

  • 反向电压裕量:在设计中建议留有安全裕量(一般 ≥20%)以应对瞬态过压与制造公差。
  • 浪涌与脉冲:Ifsm 为非重复峰值指标,若电路含频繁浪涌或重复脉冲,应采用降额或并联/选用更高 Ifsm 的器件。若数据手册未明确脉冲波形,常以 8.3 ms 半波(50 Hz)作为参考条件。
  • 热管理:尽管器件允许高结温,仍应重视结—焊盘热阻与周围散热条件,必要时在 PCB 上增加散热铜箔或隔热设计。
  • 反向恢复与开关损耗:作为开关二极管,应关注反向恢复时间与由此产生的开关损耗与 EMI,选型前务必核对数据手册中恢复时间指标。
  • 保护电路:在存在高能量瞬态时,考虑在器件前加限流电阻、RC 缓冲或 TVS 保护以延长寿命。
  • 焊接与处理:遵守制造商的焊接温度曲线与存储条件,避免长期潮湿或强酸碱环境导致性能劣化。

七、选型与替代注意

在替换或比较器件时,除了 Vr、IF 与 Ifsm,还应核实正向压降、反向漏电、反向恢复时间、最大结温以及封装尺寸与引脚间距。若电路对反向恢复速度或正向压降敏感,应优先参考完整数据手册并进行实测验证。

总结:EM516 以其高耐压、良好的浪涌能力和宽工作温度,适合多种高压开关与整流场合。合理的电路设计与热、浪涌管理可充分发挥其性能并确保长期可靠工作。若需完整电气特性曲线和机械尺寸,请索取 DIOTEC 官方数据手册以获得精确参考。

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
