SMBJ7.0CA 瞬态抑制二极管产品概述

SMBJ7.0CA是瑞隆源(RUILON)推出的一款双向贴片瞬态抑制二极管(TVS),采用SMB(DO-214AA)封装,针对电路中的瞬态过压干扰(静电放电、电快速瞬变脉冲群、浪涌等)提供快速钳位保护,适配消费电子、工业控制、汽车电子等多领域应用场景。

一、产品核心定位

作为SMB封装系列的过压防护器件,SMBJ7.0CA的核心价值在于双向无极性设计(无需区分正负极),可同时应对正负瞬态脉冲;兼顾小体积与高防护能力,适配高密度PCB布局需求,解决传统防护器件体积大、响应慢的痛点。

二、关键电气参数解析

1. 工作与防护电压

  • 反向截止电压(Vrwm):7V,即器件正常直流工作时的最大耐受电压,电路工作电压需低于此值,避免误触发。
  • 击穿电压(Vbr):8.95V(典型值),是器件从截止态转入导通态的阈值,确保瞬态过压超过此值时快速响应。
  • 钳位电压:12V(@10/1000μs脉冲),脉冲峰值时将被保护电路电压钳位至12V以内,防止后端IC、传感器等被击穿。

2. 脉冲耐受能力

  • 峰值脉冲电流(Ipp):50A(@10/1000μs波形,10μs上升沿+1000μs下降沿),可耐受较大瞬时电流冲击,应对雷击感应、电源浪涌等强干扰。
  • 峰值脉冲功率(Ppp):600W(同波形),体现器件对脉冲能量的吸收能力,满足多数工业/消费场景需求。

3. 其他关键参数

  • 反向漏电流(Ir):200μA(@Vrwm下),低漏电流确保正常工作时功耗极低,不影响电路效率。
  • 工作温度范围:-55℃~+150℃,宽温设计适配极端环境(汽车发动机舱、工业高温车间)。

三、封装与可靠性设计

SMBJ7.0CA采用SMB(DO-214AA)贴片封装,尺寸约2.3mm(长)×3.5mm(宽)×1.5mm(高),体积小、重量轻,适合高密度PCB布局;塑封材料为耐高温、耐湿环氧树脂,通过温度循环、湿度老化等可靠性测试,符合工业级长期稳定要求。

四、标准符合性与防护能力

器件符合IEC 61000-4-2(静电放电ESD) 和 IEC 61000-4-4(电快速瞬变脉冲群EFT) 国际标准,可有效防护:

  • ESD干扰:接触放电±8kV、空气放电±15kV以上(典型值);
  • EFT干扰:脉冲群重复频率5kHz、峰值电压±4kV以上(典型值); 确保被保护电路通过EMC测试,避免瞬态干扰导致设备故障。

五、典型应用场景

  1. 消费电子:手机、平板、笔记本的USB、HDMI、音频接口防护,防止插拔时静电损坏;
  2. 工业控制:PLC I/O端口、温度/压力传感器、RS485/232通信接口的浪涌防护;
  3. 汽车电子:车载导航、胎压监测传感器、CAN总线接口的过压防护(适配汽车-40℃~+125℃温区);
  4. 通信设备:路由器、交换机、光模块端口防护,应对雷击感应和静电干扰。

六、选型与使用注意事项

  1. 电压匹配:被保护电路正常工作电压需≤7V(Vrwm),避免器件长期导通;
  2. 布局建议:尽量靠近被保护端口(如连接器),减少引线电感(引线越长,防护效果越差);
  3. 功率裕量:实际应用预留20%~30%功率裕量,避免脉冲能量超额定值;
  4. 焊接要求:焊接温度≤260℃,时间≤30s,避免高温损坏塑封和芯片。

SMBJ7.0CA凭借双向防护、小体积、宽温、高脉冲耐受等优势,成为多领域过压防护的实用选择,可有效提升电路抗干扰能力与可靠性。

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.

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.

Replenishment inquiry Typical RFQ workflow
