5.0SMDJ85CA 产品概述
一、产品简介
5.0SMDJ85CA 为 Brightking（台湾君耀）出品的高能量瞬态电压抑制器（TVS 二极管），采用 SMC（DO‑214AB）封装，属于双向保护器件。该型号专为需承受高能量脉冲的线路保护设计，能在雷击、开关瞬变或其他浪涌事件发生时迅速钳位电压，保护下游器件不被过压损坏。
二、主要特性
- 极性：双向，适用于交流或双向瞬态抑制场合。
- 反向工作电压（Vrwm）：85 V，适合高压直流或中低压交流系统的工况。
- 击穿电压（Vbr）：94.4 V（典型），提供明确的导通阈值。
- 钳位电压（Vc）：约 137 V（对应峰值脉冲电流），在冲击时有效限制电压上升。
- 峰值脉冲电流（Ipp）：36.5 A（10/1000 μs 波形）；峰值脉冲功率 Ppp：5 kW（10/1000 μs），具备强劲的吸能能力。
- 反向漏电流（Ir）：2 μA（典型），静态损耗低，适合对泄漏要求敏感的应用。
- 封装：SMC（DO‑214AB），便于手工或自动化贴装与焊接，并利于散热。
三、典型应用
适用于工业电源保护、逆变器接口、通讯设备电源线、太阳能逆变器、UPS、伺服驱动器以及电机控制器等需要抑制高能量浪涌的场景。双向特性尤其适合交流电源或双向数据/信号线的浪涌防护。
四、关键参数解读与选型建议
- Vrwm（85 V）决定了常态下器件的允许工作电压，选型时应保证系统正常工作电压低于 Vrwm。
- Vbr（94.4 V）与 Vc（137 V）共同决定在浪涌发生时的导通行为与受保护设备所承受的最高电压，若下游器件耐压低于 Vc，应考虑更低钳位的器件或多级保护。
- Ipp 与 Ppp 表明对短时大能量脉冲的承受能力，5 kW/10/1000 μs 适合常见雷击及开关浪涌试验。
- 漏电流 2 μA 表明静态功耗小，利于对静态能耗敏感的系统。
五、封装、可靠性与布局注意
SMC 封装有良好热阻与机械强度，焊盘应设计为大铜面以利散热；器件应尽量靠近被保护端口放置，走线短且宽以减少寄生电感；保留良好的焊接与回流工艺，避免因过热或应力影响可靠性。针对高能量脉冲，若需要多次承受大浪涌，应评估器件在实际工况下的老化与重复冲击能力。
总结：5.0SMDJ85CA 提供了高能量吸收能力、低漏电和双向保护特性，适合工业级和电力电子场景的浪涌保护，选型时请结合系统工作电压和下游器件耐压进行综合评估。

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.
