RS1M 产品概述

一、产品简介

RS1M 为 Hottech(合科泰) 出品的快恢复/高效率整流二极管,封装为 DO-214AC (SMA),面向高压整流和电力电子应用。器件在典型工作点 1A 时正向压降仅 1.3V,反向耐压可达 1kV,具备低反向电流和较快的反向恢复特性,适合高压整流、续流保护及开关电源等场合使用。

二、主要电气参数

  • 直流反向耐压 Vr:1000 V
  • 正向压降 Vf:1.3 V @ IF = 1 A
  • 额定整流电流 IF(AV):1 A
  • 反向电流 Ir:≤ 5 μA @ Vr = 1 kV
  • 反向恢复时间 Trr:≈ 500 ns
  • 非重复峰值浪涌电流 Ifsm:35 A
  • 工作结温范围:-65 ℃ ~ +150 ℃
  • 封装:DO-214AC (SMA)

三、主要特性

  • 快恢复特性,降低开关损耗与开关瞬态能量耗散,有利于提高转换效率;
  • 高耐压 (1 kV),适用于高压整流和高压保护场合;
  • 低正向压降和低静态反向泄漏,减少导通损耗并降低空载或低负载下的漏电损耗;
  • SMA 表面贴装封装,适合自动化贴装与批量生产;
  • 宽工作温度范围,满足汽车级及工业级温度要求。

四、典型应用场景

  • 开关电源(SMPS)高压整流;
  • 工业变换器和逆变器的续流/整流回路;
  • 高频脉冲及脉冲功率电路;
  • PFC(功率因数校正)二极管阵列;
  • 高压电源、医疗仪器(符合相应规范时使用)、测试设备的高压保护电路。

五、设计与选型建议

  • 在长期工作时应考虑结温升高对正向压降和反向泄漏的影响,必要时对器件进行热仿真并在 PCB 上提供散热铺铜或热垫;
  • 在重复开关场合,尽管 Trr 为 500 ns 已属快恢复范畴,但在 GHz 级或极高频率应用中仍需评估开关损耗与电磁干扰(EMI),必要时并联肖特基或采用 snubber / RC 吸收网络;
  • 若需并联提高平均电流能力,应注意器件正向压降的一致性并保证良好热均衡;
  • 对于浪涌环境,应验证 Ifsm 35 A 的脉冲能力是否满足冲击能量要求,并考虑外加浪涌保护器件。

六、封装与焊接注意事项

  • DO-214AC (SMA) 为常见的表面贴装封装,建议采用合适的回流焊工艺与稳态升温曲线,以避免封装应力和过热;
  • 焊盘设计应参考厂方建议以保证热性能与机械强度;
  • 焊接后建议进行目视/显微检查和必要的电气测试,避免冷焊或焊点裂纹。

七、可靠性与测试建议

  • 出货前建议进行高压泄漏测试、正向压降一致性测试和 Trr 测试以确认性能指标;
  • 长期可靠性评估应包括高温高湿、热循环和浪涌冲击试验;
  • 在系统验证阶段,应在最大工作结温和极端工况下复核反向电流、正向压降和恢复特性。

八、结论与采购信息

RS1M(Hottech/合科泰,DO-214AC 封装)是一款面向高压、高效率整流和快恢复场合的实用二极管,适合用于高压整流、电源保护及功率电子模块。欲获取样品、数据手册或大宗采购信息,请联系 Hottech 授权分销商或合科泰官方渠道。

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
