SMCJ28CA 瞬态抑制二极管（TVS）产品概述
一、产品基本信息
SMCJ28CA是RUILON（瑞隆源） 推出的一款双向瞬态抑制二极管（TVS），采用SMC（DO-214AB） 贴片封装，体积小巧（约2.7×1.7×1.1mm），适配高密度PCB设计。器件工作温度范围为**-55℃~+150℃**，覆盖工业级、汽车级等极端环境需求，是电子电路浪涌保护的通用型器件。
二、核心电气参数解析
SMCJ28CA的关键参数围绕“浪涌抑制能力”和“电路兼容性”设计，核心参数及意义如下：
参数名称 典型值/规格 实际意义 反向截止电压（Vrwm） 28V 正常工作时反向偏置不导通的最大电压，需匹配电路工作电压（如24V系统适配） 击穿电压（Vbr） 35.8V 浪涌触发时开始导通的阈值电压，确保正常电压下不干扰电路 钳位电压（Vc） 45.4V 浪涌电流峰值时的最高电压，钳位比≈1.27（Vc/Vbr），越低保护效果越好 峰值脉冲电流（Ipp） 33.1A@10/1000μs 10/1000μs标准浪涌波形下的最大耐受电流，应对瞬时浪涌冲击 峰值脉冲功率（Ppp） 1.5kW@10/1000μs 对应波形下的最大功率容量，覆盖常见浪涌能量（雷击、开关浪涌等） 反向漏电流（Ir） 5μA 正常工作电压下的漏电流，数值极低，不增加电路功耗或干扰信号三、主要应用场景
SMCJ28CA因双向保护、宽温特性和小封装，广泛应用于以下领域：
- 汽车电子：车载导航、仪表盘、传感器（如胎压监测）、电源端口的浪涌保护（适配汽车-40℃~+125℃环境）；
- 消费电子：手机、平板、笔记本的USB接口、充电端口（应对静电放电ESD、浪涌冲击）；
- 工业控制：PLC、伺服驱动器、工业传感器节点的电源/信号端口（抑制工业环境高能浪涌）；
- 通信设备：路由器、交换机、基站的以太网口、电源输入口（防护雷击或电磁干扰浪涌）；
- 电源系统：开关电源、UPS的输出端（限制电压尖峰，保护后级负载）。
四、产品优势特点
- 双向保护简化设计：无需区分正负极，适配正反向浪涌场景（如双向信号传输、电源端口）；
- 低钳位比高效防护：钳位电压仅45.4V，远低于敏感器件（如MCU、传感器）的耐压阈值，避免过压损坏；
- 宽温稳定可靠：-55℃~+150℃覆盖工业/汽车级环境，长期工作无性能衰减；
- 小封装高密度布局：SMC贴片封装适合小型化产品（如可穿戴设备、便携仪器）；
- 低漏电流低功耗：5μA反向漏电流不影响电路正常工作，无额外功耗负担。
五、使用注意事项
- 选型匹配：Vrwm需≥电路最大工作电压（如24V系统选28V，避免正常工作导通）；
- 焊接规范：焊接温度≤260℃，时间≤3秒，防止高温损坏器件；
- 布局优化：TVS需并联在被保护器件引脚/端口附近，减少引线电感（引线越长，保护效果越差）；
- 浪涌验证：若实际浪涌能量超过参数范围（如高能雷击），需并联多个器件或采用多级保护；
- 存储条件：未焊接器件存于干燥环境（-10℃~+40℃，湿度≤60%），避免受潮影响性能。
SMCJ28CA作为瑞隆源的成熟TVS产品，以高性价比、可靠性能成为电子电路浪涌防护的主流选择，适配多行业应用需求。

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.
