BV-SMBT-30CA 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心价值

BV-SMBT-30CA是Bencent(槟城)品牌推出的双向瞬态抑制二极管(TVS),核心作用是快速泄放电路中的瞬态浪涌能量,将过压钳位在安全范围内,保护后端敏感电子元件(如MCU、传感器、通信模块等)免受雷击、静电放电(ESD)、电源开关瞬态等冲击损坏。

该器件针对低压直流电路的宽环境应用设计,平衡了浪涌耐受能力、低功耗和紧凑封装,适合汽车电子、工业控制、消费电子及通信设备等领域的过压防护需求,尤其适配12V/24V低压系统。

二、关键电气参数与应用意义

TVS的核心性能由电气参数决定,BV-SMBT-30CA的参数精准适配多数低压场景:

2.1 双向极性设计

无需区分正负极,简化电路布线(尤其适合电源正负浪涌或信号双向传输的场景),避免因极性接反导致的保护失效,降低设计与生产错误风险。

2.2 反向截止电压(Vrwm=30V)

正常工作时,TVS处于截止状态,不影响电路信号或电源传输。30V的Vrwm适配12V/24V低压系统(如汽车12V电源、工业12V控制电路),留足电压裕量(系统最大工作电压通常不超15V),确保稳定运行。

2.3 峰值脉冲电流(Ipp=200A@8/20μs)

采用国际标准的8/20μs浪涌波形(模拟雷击或电源瞬态),200A的耐受能力可应对强浪涌冲击(如户外设备的雷击浪涌、工业电源的开关瞬态),快速泄放能量,避免后端元件因过流烧毁。

2.4 击穿电压(32V)

当浪涌电压超过32V时,TVS迅速击穿导通(响应时间<1ns),将电压钳位在安全范围(约32V~35V,具体取决于电流),既不影响正常工作,又能有效保护敏感元件。

2.5 反向漏电流(Ir=1μA)

正常工作时漏电流极小,不消耗额外功率,适合低功耗/电池供电设备(如便携式医疗设备、智能穿戴),避免因TVS漏电流导致电池过度放电,延长续航时间。

2.6 宽温工作范围(-40℃~+125℃)

覆盖汽车级温区要求,可在极端环境(如汽车发动机舱、户外通信基站)稳定工作,不受温度变化影响电气性能。

三、SMB封装的机械特性

BV-SMBT-30CA采用SMB(DO-214AA)贴片封装,具有以下优势:

  • 紧凑体积:尺寸约2.3mm×4.3mm×1.5mm,适合高密度PCB设计(如智能手机、车载控制器);
  • 焊接兼容性:支持回流焊、波峰焊,适配自动化生产流程,提高生产效率;
  • 机械强度:封装结构抗振动、抗冲击,适合汽车、工业等振动环境;
  • 散热性能:贴片结构利于热量扩散,避免浪涌后温度累积影响性能。

四、典型应用场景

结合参数与封装,BV-SMBT-30CA的典型应用包括:

  1. 汽车电子:车载MCU、传感器(如胎压监测、摄像头)、车载充电器的电源端保护;
  2. 工业控制:PLC输入输出端口、传感器模块、伺服驱动器的过压防护;
  3. 消费电子:智能手机/平板的充电接口、耳机接口的ESD与浪涌保护;
  4. 通信设备:路由器、交换机的以太网端口、电源模块的雷击防护。

五、选型与使用注意事项

为确保保护效果,选型时需注意:

  • 确认电路工作电压≤30V(Vrwm),避免TVS误导通;
  • 浪涌电流峰值≤200A(Ipp),若浪涌更强需并联多个器件;
  • 双向极性适合无需区分正负极的电路,若为单向电路需确认对应型号;
  • 宽温区(-40℃~+125℃)适合极端环境,常温场景也可兼容。

BV-SMBT-30CA凭借双向防护、强浪涌耐受、宽温适配等特性,成为低压电路过压保护的高性价比选择,可有效提升电子设备的可靠性与使用寿命。

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.
