产品概述:SMBJ36CA 压敏二极管
一、产品基本信息
二、产品定义
SMBJ36CA 是一种表面贴装(SMB)保护器件,属于压敏二极管(TVS,Transient Voltage Suppressor)系列。它主要用于保护敏感电子设备和电路免受瞬态过电压的影响,常见于电源保护、数据线路以及信号线路的过压保护应用中。
三、主要特性
潮流保护能力:SMBJ36CA 具有快速反应能力,能够在瞬态电流(如浪涌或雷击引起的电压尖峰)到达时迅速导通,从而有效保护下游电路的元件不受损害。
双向保护:该器件提供双向保护,能够同时对正向和反向电压尖峰提供保护,适合在对称的电路环境中使用。
额定电压:SMBJ36CA 的击穿电压通常为 36V,使得它能够支持多种应用场景的电气安全需求。
低泄漏电流:在正常工作条件下,SMBJ36CA 的泄漏电流极低,意味着在不发生过电压保护情况下,将不会消耗多余的电力。
热耗散能力:以 SMB 封装制造,使其具备出色的热管理性能,能够在高温环境下保持良好的工作状态。
小尺寸:SMB 封装使得其体积小巧,方便进行表面贴装,对PCB(印刷电路板)设计友好。
四、应用领域
电源管理:在电源转换器和适配器中使用,以保护电路免受高电压瞬变的损坏。
通信设备:如路由器、交换机、光纤通信设备等,SMBJ36CA 可以为这些设备提供高效的电压浪涌保护,确保数据传输的稳定性。
消费电子:在手机、平板电脑、电视等消费电子产品中,保护内部电子元件,预防电压不稳导致的损坏。
工业应用:在电动工具、工业控制系统等设备中,也常常用到此种压敏二极管,以提高设备的耐用性和可靠性。
五、安装与使用注意事项
在使用 SMBJ36CA 进行电路设计时,有几个注意事项:
正确接地:确保器件与地面形成良好的接地连接,以提高浪涌保护的效能。
合理布局:在 PCB 布局上,应尽量缩短 SMBJ36CA 与被保护元件间的连线,降低寄生电感,提高瞬态响应速度。
根据负载选择:选择合适的压敏二极管应根据系统的具体需求和操作电压来确定,确保器件的准备参数切合实际要求。
六、总结
SMBJ36CA 是一款高效能的保护型电子元器件,具有诸多优良特性,能够满足现代电子设备对过电压保护的严苛需求。无论是在消费电子、通信还是工业应用中,它都展现出了不可替代的价值。通过合理的设计与应用,SMBJ36CA 能够为各种电路系统提供持久的保护和性能支持。选择MSKSEMI的SMBJ36CA,可以为稳定安全的电力系统奠定坚实基础。
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.
