BV-SMBJ30A 单向瞬态抑制二极管(TVS)产品概述

一、产品定位与核心功能

BV-SMBJ30A是一款单向瞬态抑制二极管(TVS),专为低电压电路的瞬态浪涌/过压防护设计,可快速响应静电放电(ESD)、雷击浪涌、电源开关瞬态等异常电压,将电路电压钳位在安全范围内,保护敏感电子元器件(如MCU、传感器、通信芯片等)免受损坏,是消费电子、工业控制、汽车电子等领域的高性价比防护器件。

二、关键参数深度解析

该器件核心参数直接决定防护性能,具体解析如下:

  1. 反向截止电压(Vrwm):30V
    正常工作状态下,反向可承受的最大连续电压,若电路电压未超过此值,TVS处于截止状态,不影响电路正常运行(如5V/12V电源系统的防护适配性强)。
  2. 击穿电压(Vbr):36.8V
    当反向电压达到36.8V时,TVS开始可逆性瞬态击穿导通,进入防护模式(非永久性损坏,浪涌消失后恢复截止状态)。
  3. 钳位电压(Vc):48.4V
    浪涌脉冲作用下,TVS将电路电压钳位至48.4V以内,此值是保护后级器件的关键阈值(需确保后级器件耐压≥钳位电压)。
  4. 峰值脉冲功率(Ppp):600W@10/1000μs
    采用“10μs上升时间+1000μs半峰值时间”的标准浪涌波形时,器件可承受的最大脉冲功率,覆盖常见雷击、开关瞬态浪涌场景。
  5. 峰值脉冲电流(Ipp):12.4A@10/1000μs
    对应600W脉冲功率下的峰值电流,反映器件抗大电流浪涌的能力,可有效抑制强瞬态冲击。
  6. 反向漏电流(Ir):1μA
    正常工作时反向漏电流极低,避免对电路功耗、信号传输造成干扰(如敏感模拟电路的防护适配性好)。
  7. 工作温度范围:-55℃~+150℃
    宽温设计,可适应工业级(-40℃~+85℃)、车载级(部分高温场景)等极端环境。

三、封装设计与可靠性保障

  1. SMB(DO-214AA)封装
    采用贴片式SMB封装,体积小巧(约2.4×5.0×1.0mm),适合高密度PCB布局;引脚间距合理,焊接工艺兼容性强(回流焊、波峰焊均可),批量生产效率高。
  2. 防护等级与可靠性
    符合IEC 61000-4-2静电放电防护标准,可有效抑制±8kV(接触放电)、±15kV(空气放电)的ESD冲击;封装采用耐高温环氧树脂,防潮、抗机械应力能力强,长期可靠性高(平均无故障时间MTBF≥10^6小时)。

四、典型应用场景

BV-SMBJ30A因参数适配性强,广泛应用于以下领域:

  1. 消费电子:手机、平板、笔记本电脑的电源端口、USB接口防护;充电器、充电宝的输入输出过压防护。
  2. 工业控制:PLC控制器、传感器接口、伺服驱动器的浪涌防护;工业电源模块的瞬态抑制。
  3. 通信设备:路由器、交换机、光模块的以太网端口、射频接口防护。
  4. 汽车电子:车载显示屏、倒车雷达传感器、辅助驾驶模块的过压防护(适配-55℃~+150℃宽温)。
  5. 电源系统:DC-DC转换器、LED驱动电源的输入输出防护,防止开关瞬态损坏。

五、品牌与质量优势

Bencent(槟城)作为专业电子元器件品牌,BV-SMBJ30A具备以下优势:

  • 工艺控制:采用先进的硅芯片制程,精准控制击穿电压一致性(偏差≤5%),漏电流稳定在1μA以内,批量一致性好。
  • 环保认证:产品符合RoHS、REACH环保标准,无铅无卤,适配全球市场需求。
  • 成本效益:在保证防护性能的前提下,提供高性价比方案,降低终端产品防护成本(单颗成本低于同规格进口器件15%~20%)。

综上,BV-SMBJ30A是一款参数均衡、可靠性高、应用场景广泛的单向TVS管,可满足多领域低电压电路的瞬态过压防护需求。

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
