HS1D 产品概述

HS1D 是扬杰(YANGJIE)推出的一款通用开关二极管,采用 SMA (DO-214AC) 封装,针对中低功率开关电源、整流及保护应用优化设计。器件兼顾良好的开关性能与较低正向压降,适用于需要快速恢复特性的线路和有限空间的表面贴装场合。

一、主要参数

  • 正向压降 (Vf):1.0 V @ 1.0 A
  • 直流反向耐压 (Vr):200 V
  • 整流电流:1 A (持续)
  • 反向电流 (Ir):≤ 5 μA(典型测量条件见厂方资料)
  • 反向恢复时间 (Trr):50 ns
  • 非重复峰值浪涌电流 (Ifsm):30 A
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SMA (DO-214AC)
  • 品牌:YANGJIE(扬杰)

二、产品特性

  • 低正向压降,减少导通损耗,适合提高效率的开关及整流电路。
  • 快速反向恢复(Trr≈50ns),在高频开关场合能有效降低开关损耗与电磁干扰幅度。
  • 200V 反向耐压满足多数中低压电源与阻断需求。
  • 小尺寸 SMA 封装,便于表面贴装自动化生产与版面密集设计。
  • 高浪涌承受能力(Ifsm 30A),对短时突发过流有一定缓冲能力。

三、典型应用场景

  • 开关电源(SMPS)次级整流与快速整流。
  • 逆变器、DC-DC 转换器中的开关/钳位元件。
  • 充电器、适配器及电视、机顶盒等消费电子电源。
  • 保护电路、吸收尖峰脉冲和快速钳位用途。

四、封装与机械注意事项

  • SMA (DO-214AC) 小型贴片封装,适配常见回流焊工艺。
  • 焊盘设计建议增加散热铜箔面积以降低结温;在高平均功率场合采用散热过孔或铜箔扩展。
  • 注意回流焊温度曲线与制造商推荐的焊接规范,避免过高温度或过长加热时间影响可靠性。

五、热管理与可靠性建议

  • 虽然器件允许结温上限为 +150 ℃,为延长寿命与提升可靠性,实际工作中建议留有余量,常用环境下结温不宜长期接近上限。
  • 对于持续接近 1A 的工作状态,应评估 PCB 散热设计并做必要的电流/温度仿真或实测。
  • 在高频开关应用中,反向恢复会引起瞬态电压与电流尖峰,必要时配合吸收电路或缓冲网络以减少应力。

六、使用注意事项

  • 峰值浪涌 Ifsm 的能力为非重复脉冲能力,应避免在重复或长时间脉冲中超过额定值;具体波形和时长请参照厂方浪涌测试条件。
  • 反向电流随温度上升显著增大,关键温度点应在设计中考虑漏电和热耗散。
  • 若用于高频高电压场合,应关注 Trr 对系统 EMI 与能量损耗的影响,必要时选用专用快速恢复或肖特基器件对比验证。

七、质量检测与选型建议

  • 选型时应参考厂方完整数据手册以确认典型曲线(Vf-T、Ir-V、Trr 波形等)。
  • 推荐在样机阶段做实际应用环境下的功耗、温升与电磁兼容测试。
  • 对于关键或高可靠性产品,建议与供应商确认批次一致性、可靠性试验及可追溯性信息。

HS1D 以其平衡的导通特性、较快恢复速度与小型封装,为中低压开关与整流应用提供了经济且可靠的选择。选用时请结合具体工作条件、浪涌要求与散热方案进行验证。

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
