JUXING(钜兴)3SPC090F 三相过压保护器件产品概述

一、产品定位与核心价值

JUXING(钜兴)3SPC090F是一款专为三相电路设计的瞬态抑制二极管(TVS)阵列,核心作用是快速抑制电路中的瞬态过压(如雷击感应浪涌、电源开关切换尖峰、静电放电等),保护后端敏感电子元件(MCU、传感器、通信模块等)免受损坏。相比传统单极TVS需多器件组合保护三相,该产品通过集成3极结构实现单器件三相防护,既简化电路设计,又降低物料成本与PCB占用空间,适合对防护效率、体积有要求的工业及通信设备场景。

二、关键性能参数深度解析

该器件的核心参数围绕「三相防护+宽温可靠+低电容兼容高频」展开,具体解析如下:

1. 三相集成设计

极数为3,可同时对三相电路的相线-地/相线-中性线之间的过压进行防护,无需额外增加单极TVS器件,避免多器件参数不一致导致的防护不均问题,减少电路复杂度。

2. 击穿电压与精度

直流击穿电压(Vdc)为90V±20%,匹配多数低压三相电路的工作电压(如48V直流三相系统、交流220V整流后的低压分支电路);精度±20%属于工业级TVS的常规精度,满足批量应用的一致性需求,避免因击穿电压偏差导致的防护失效或误触发。

3. 浪涌承受能力

脉冲放电电流(8/20μs标准波形)达5kA,可有效抑制常见工业场景中的中等强度浪涌(如距离雷击点100米内的感应浪涌、大功率设备开关切换产生的尖峰);且器件可重复承受多次浪涌冲击,无需频繁更换,降低维护成本。

4. 低电容特性

极间电容仅1pF,远低于普通TVS的几十pF水平,对高频信号传输的损耗极小(如100MHz信号的传输延迟可忽略),因此可同时用于「三相供电+高频数据传输」共存的场景(如通信基站的三相电源模块+高速数据接口防护)。

5. 宽温工作范围

工作温度覆盖**-40℃~+90℃**,满足工业现场的极端温度需求(如北方户外设备冬季低温、南方机房夏季高温),无需额外增加温控措施,提升设备环境适应性。

6. 小型化封装

封装尺寸为5x7.6mm,长度7.6mm,属于表面贴装小型封装,可直接焊接在PCB上,节省约30%的安装空间,适合紧凑型设备(如小型PLC、手持测试仪器)的内部布局。

三、典型应用场景

3SPC090F的参数特性使其在多个领域具有广泛应用:

1. 工业控制设备

  • 小型PLC的三相供电输入端防护,保护CPU及输入输出模块免受浪涌冲击;
  • 工业传感器(温度、压力传感器)的三相供电接口防护,避免传感器因过压损坏。

2. 通信基站设备

  • 基站三相电源模块的过压防护,保护射频模块、基带处理单元;
  • 小型通信设备(微基站)的内部三相供电电路防护。

3. 新能源领域

  • 小型光伏逆变器的输入输出端防护(针对低压直流三相电路);
  • 小型储能系统的三相供电接口防护。

4. 工业级医疗设备

  • 小型监护仪、输液泵等设备的三相供电防护,满足医疗设备的可靠性要求。

四、产品优势总结

  1. 三相集成防护:单器件替代3个单极TVS,简化电路设计,降低物料成本;
  2. 低电容兼容高频:1pF极间电容不影响高速信号传输,兼顾供电与信号防护;
  3. 宽温可靠耐用:-40℃~+90℃适应工业恶劣环境,重复浪涌冲击下性能稳定;
  4. 高浪涌容量:5kA脉冲电流满足中等强度浪涌防护需求,覆盖多数工业场景;
  5. 小型化设计:5x7.6mm封装节省PCB空间,适合紧凑型设备布局。

该产品依托JUXING(钜兴)的工业级器件制造经验,在性能与成本之间实现平衡,是三相电路过压防护的高性价比选择。

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.
