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。
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:
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。
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。
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。
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)。
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。
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。
3SPC090F的参数特性使其在多个领域具有广泛应用:
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。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
