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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
