US1D_R1_00001 产品概述

一、主要参数与型号

US1D_R1_00001 是 PANJIT(强茂)出品的一款独立式快恢复/高效率整流二极管,面向开关电源与一般功率整流场合。主要电气与环境参数如下:

  • 二极管配置:独立式(单只器件)
  • 正向压降(Vf):1.0 V @ IF = 1 A
  • 直流反向耐压(Vr / Vrrm):200 V
  • 额定整流电流:1 A(直流)
  • 反向电流(Ir):约 1 µA(典型)
  • 反向恢复时间(Trr):100 ns(典型,快恢复特性)
  • 工作结温范围:-55 ℃ ~ +150 ℃(Tj)
  • 封装:SMA(DO-214AC)
  • 品牌:PANJIT(强茂)
  • 型号:US1D_R1_00001

二、产品特性

  • 快恢复性能:100 ns 级别的反向恢复时间可显著减少在高频开关条件下的瞬态损耗和开关过冲,适合中低功率开关电源、DC-DC 转换器及逆变器等。
  • 低正向压降:1 V(1 A)有助于降低导通损耗,提升效率,尤其在电流较大或长导通时间的场合更为明显。
  • 低反向泄漏:约 1 µA 的反向电流在高耐压情况下保持较小泄漏,有利于降低空载功耗并提高系统稳定性。
  • 宽温度工作范围:-55 ℃ 至 +150 ℃ 的结温范围保证了在严苛环境或温度起伏大的应用中具有良好可靠性。
  • 典型封装优势:SMA(DO-214AC)小巧且具备良好的散热路径,适合自动化贴片与手工焊接两种生产方式。

三、典型应用场景

  • 开关电源(SMPS)次级整流或同步整流替代件
  • 通用整流、适配器、充电器输出整流
  • 电机驱动的续流或反并联二极管
  • LED 驱动电源的整流或回路保护
  • 电池充放电管理及逆变器辅助整流
  • 其他需要在中高频率下工作且要求较低开关损耗的功率整流场合

四、封装与安装建议

  • 封装为 SMA(DO-214AC),外形紧凑,适用于表面贴装(SMT)工艺,可兼容自动点料与贴装设备,利于规模化生产。
  • 焊接时建议参考封装厂的推荐焊盘尺寸与回流曲线,以保证焊点可靠性与热阻最低化。
  • 封装导热能力有限,建议在 PCB 设计时为该器件配备较大铜箔散热区或与散热片通过铜箔/过孔联通,以降低结温、提高长期可靠性。

五、热管理与可靠性

  • 虽然器件允许结温最高可达 150 ℃,但为延长使用寿命并保证长期稳定性,实际设计时应控制器件结温在安全裕度范围内(如 ≤ 125 ℃)并做好散热设计。
  • 在高脉冲电流或瞬间浪涌条件下,应评估是否需要额外的浪涌吸收或限流措施,防止超出器件的瞬态承受能力(请在系统层面验证IFSM/浪涌能力,若需更精确参数建议参考完整 datasheet)。
  • 快恢复二极管在高频工作时仍会产生开关损耗和 EMI,布局上应尽量缩短高 di/dt 环路并做合理接地与滤波设计。

六、检验与采购信息

  • 订购时请明确型号 US1D_R1_00001 及品牌 PANJIT(强茂),并确认封装 SMA(DO-214AC)。
  • 采购前建议索取并核对完整 datasheet 与可靠性测试报告(如有需要,可要求厂家提供 Trr、Ir 随温度变化曲线以及典型 V‑F 曲线)。
  • 对于关键应用,建议先进行小批量样品验证,包括温升测试、循环应力测试和电磁兼容测试。

七、常见注意事项

  • 本型号为单只独立器件,非表面叠层或模块化封装;在设计并联使用时需考虑电流分配的不均匀性。
  • 反向耐压 200 V,超出此电压可能导致击穿或永久损伤;实际电路应留有安全裕度并必要时加保护元件。
  • 反向恢复特性在不同电流、温度及测试条件下会有变化,设计时应以实际系统波形和频率为准进行评估。

总体来说,US1D_R1_00001 是一款面向中低功率、高效率整流与快恢复需求的通用二极管,适用于需要在 200 V 等级电压下工作、对开关损耗与反向泄漏有较高要求的电子产品。 若需更详细的电气特性曲线及机械尺寸,请参阅 PANJIT 官方 datasheet 或联系供应商获取完整技术资料。

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.
