US1K_R1_00001 产品概述
一、简介
US1K_R1_00001 是强茂（PANJIT）推出的一款独立式快恢复/高效率二极管，封装为 SMA (DO-214AC)。该器件面向高压开关和整流场合，具有800V的反向耐压能力、1A的整流电流等级以及较低的反向漏电和中等恢复时间，适合交流-直流转换、PFC、逆变器和电源保护等应用。
二、主要参数
- 二极管配置：独立式
- 正向压降（Vf）：1.7V @ If = 1A
- 直流反向耐压（Vr）：800V
- 最大整流电流：1A（直流）
- 反向电流（Ir）：1 μA @ Vr = 800V
- 反向恢复时间（Trr）：100 ns
- 工作结温范围（Tj）：-55℃ ~ +150℃
- 封装：SMA (DO-214AC)
注：详尽的电气/热特性、浪涌能力及频率相关损耗，请参见厂商数据手册。
三、产品特点
- 高电压耐受：800V 反向耐压，适合中高压整流与开关环境。
- 低反向漏电：在Vr=800V 时 Ir 典型为 1 μA，有利于提高空载效率与降低待机损耗。
- 快恢复特性：Trr≈100 ns，比普通慢恢复二极管损耗与开关交越时间更小，适配较高开关频率的电源拓扑。
- 可靠封装：SMA/DO-214AC 封装便于自动贴装与回流焊，兼顾散热与体积。
四、典型应用场景
- 开关电源（SMPS）高压整流与续流；
- 功率因数校正（PFC）电路高压侧整流；
- 逆变器/变频器的自由轮回与钳位电路；
- 电源适配器、电视、电源板及工业电源等需要800V耐压的场合。
五、封装与安装建议
- 封装为 SMA (DO-214AC)，焊接采用常规回流工艺；焊接温度与时间应遵循强茂推荐回流曲线以保证可靠性。
- PCB 布局建议：整流/续流路径尽量短且宽，减少寄生电感；必要时在焊盘附近增加散热铜箔或通孔散热。
- 极性识别：器件表面有极性标记，注意放置方向以免倒装。
六、可靠性与应用注意
- 虽然器件最高结温可达 +150℃，但长期可靠性通常要求在制造商推荐的结温范围内工作，并在高温下按厂方的降额曲线使用。
- 在高频开关场合，考虑反向恢复引起的瞬态应力和电磁干扰，必要时配合 RC 浪涌吸收或软恢复拓扑。
- 对于关键设计，请参考强茂完整数据手册中的热阻、浪涌电流能力和典型特性曲线来做热与电气降额设计。
七、采购与替代
- 品牌：PANJIT（强茂）；型号：US1K_R1_00001；封装：SMA。
- 若需更低正向压降或更短恢复时间，可考虑 Schottky（二极管）或超快恢复（UFR）系列，但需注意电压等级与漏电差异。
- 采购时建议索取原厂数据手册与样品进行电路验证。
如需我帮您核对具体电气曲线、热阻或与现有电路的兼容性评估，请提供电路工作条件（最大电流、开关频率、环境温度等）。

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.
