BDFN2C3R31V 双向瞬态抑制二极管产品概述

BDFN2C3R31V是伯恩半导体(BORN)推出的一款高性能双向瞬态抑制二极管(TVS),专为敏感电子电路的过压防护设计,具备紧凑封装、低寄生电容、高脉冲耐受能力等核心优势,可有效抑制静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌(Surge)等瞬态干扰,广泛适用于消费电子、物联网、工业控制等领域。

一、核心防护性能参数

该器件的核心防护参数围绕过压响应速度与脉冲耐受能力展开,可覆盖绝大多数常见瞬态干扰场景:

  • 双向极性:支持正负脉冲双向防护,无需额外设计反向并联电路,简化PCB布局;
  • 反向截止电压(Vrwm)3.3V:正常工作状态下不导通,避免对电路正常信号/电源造成影响;
  • 钳位电压8V:当瞬态过压超过击穿阈值时,器件快速导通并将电压钳位至8V以内,保护后端敏感元件(如MCU、传感器等);
  • 峰值脉冲电流(Ipp)10A@8/20us:符合IEC标准的8/20us浪涌波形下,可耐受10A峰值电流,能应对电源或信号线路的中等强度浪涌;
  • 峰值脉冲功率(Ppp)80W@8/20us:对应10A×8V的脉冲功率,确保器件在瞬态干扰下不会因能量过载损坏。

二、电气特性关键指标

除防护参数外,电气特性直接影响器件对正常电路的兼容性:

  • 击穿电压4.2V:高于反向截止电压3.3V,保证正常工作时器件处于截止状态,无额外功耗;
  • 反向电流(Ir)200nA:漏电流极低,不会增加电路静态功耗,尤其适合低功耗应用(如可穿戴设备、物联网节点);
  • 结电容(Cj)12pF:低结电容是高速信号线路防护的关键——过高的电容会导致信号失真,12pF的指标可兼容USB2.0、I2C、SPI等高速接口,不影响信号完整性。

三、适用电磁兼容标准

BDFN2C3R31V满足三大核心EMC标准,覆盖电子设备常见干扰场景:

  • IEC 61000-4-2(ESD):应对人体接触或设备间的静电放电(典型±8kV接触放电、±15kV空气放电);
  • IEC 61000-4-4(EFT):抑制快速脉冲群干扰(如开关操作、电机启动产生的瞬态脉冲);
  • IEC 61000-4-5(Surge):防护雷电感应或电源系统浪涌(典型2kV/100A浪涌)。

这些标准的符合性,确保器件可直接用于需通过EMC认证的产品设计。

四、小型化封装与典型应用

采用DFN1006封装(尺寸1.0mm×0.6mm×0.5mm),无引脚设计可降低寄生电感,同时节省PCB空间,适合高密度布局场景:

  • 消费电子:智能手机/平板的USB接口、充电口、耳机孔防护;
  • 物联网:传感器节点、无线模块(如WiFi、蓝牙)的信号/电源线路防护;
  • 工业控制:小型PLC、远程IO模块的输入输出接口防护;
  • 可穿戴设备:智能手表、手环的低功耗电路防护(低漏电流+小尺寸)。

五、品牌与可靠性优势

伯恩半导体(BORN)是国内专注于防护器件的专业厂商,具备成熟的晶圆制造与封装测试能力:

  • 器件参数一致性好,批量应用中防护性能稳定;
  • 结电容、漏电流等指标控制严格,符合高速电路设计要求;
  • 经过高低温循环、湿度老化等可靠性测试,可满足工业级或消费级产品的长期使用需求。

总结

BDFN2C3R31V凭借双向防护、低电容、高脉冲耐受、小型化封装等综合优势,成为敏感电子电路过压防护的高性价比选择。其对多类EMC标准的符合性,以及与高速信号的兼容性,使其可广泛应用于消费电子、物联网、工业控制等领域,为设备提供可靠的瞬态干扰防护。

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
