SM516 产品概述
一、产品简介
SM516 是 DIOTEC（德欧泰克）推出的一款高压通用整流二极管，针对高电压整流与防护场合优化设计。器件标称直流反向耐压高达 1.6 kV，额定整流电流 1 A，适合在需要高耐压、小体积和可靠性的电源与高压电路中使用。封装为 DO-213AB，便于安装与热管理。
二、主要参数（典型标称）
- 正向压降 Vf：1.1 V @ IF = 1 A（标称工作点）
- 直流反向耐压 VR：1.6 kV
- 额定整流电流 IF(AV)：1 A
- 反向电流 Ir：5 μA @ VR = 1.6 kV（常温下标称）
- 非重复峰值浪涌电流 Ifsm：44 A（单次脉冲允许值）
- 工作结温范围 Tj：-50 ℃ ~ +175 ℃
- 品牌：DIOTEC（德欧泰克）
- 封装：DO-213AB
三、器件特点与优势
- 高耐压：1.6 kV 的反向耐压使其可用于高压整流、倍压器、HV 电源及CRT、X 射线发生器等高电压场合。
- 低漏电：在满额定反压下反向电流低至 μA 级，有利于低功耗和高压稳定性。
- 良好冲击能力：44 A 的非重复峰值浪涌电流允许器件承受启动或瞬态冲击。
- 宽工作温度：-50 ℃ 至 +175 ℃ 的结温范围，适应工业及严苛环境应用。
- 封装利于装配：DO-213AB 结构适配常见贴装与焊接工艺，便于量产。
四、典型应用场景
- 高压整流电源、高压倍压器与整流模块；
- 开关电源（高压侧）、电源保护电路与吸收钳位；
- 工业激励电源、电子显像与高压测试设备；
- 需要低漏电与高耐压的传感、测量与防护场景。
五、使用与热管理建议
- 正向压降随电流上升而增加，在长期 1 A 工作时应确认散热通道，必要时在 PCB 上加大铜箔或配置散热垫以控制结温。
- 浪涌电流 Ifsm 为非重复峰值，使用中应避免重复且长期的高幅值冲击；若存在重复冲击，请按能量与频率进行适当降额。
- 反向漏电受温度影响显著，若在高温工况使用，需考虑 Ir 增加对电路的影响并适当预留裕量。
- 工作结温不得超过 +175 ℃，器件长期可靠性建议在温度低于该极限并遵循厂商的焊接与回流曲线。
六、选型与可靠性提示
- 若系统对正向压降敏感，可考虑选用低 Vf 型号或并联多只器件并做好电流均衡；但并联时要注意均流与压降匹配。
- 对于高频切换或快速脉冲应用，需评估二极管的恢复特性（如无显式提供，可咨询厂方获取动态参数）。
- 在高海拔或特殊环境（强电磁、振动）下使用，应配合相应的试验与验证，确保长寿命与稳定性。
总结：SM516 以其 1.6 kV 的高耐压、1 A 的整流能力与低漏电特性，适合各种高压整流与防护场合。合理的热设计与正确的使用方式能发挥其在严苛环境下的可靠性能。如需更详细的电气特性曲线、封装尺寸和回流焊工艺，请参考 DIOTEC 官方数据手册或联系厂方技术支持。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
