BDFN2C2R51V 产品概述

一、产品简介

BDFN2C2R51V 是 BORN(伯恩半导体)推出的一款双向瞬态电压抑制器(TVS),以超小体积封装实现对低电压敏感线缆和信号接口的有效浪涌与静电放电保护。器件采用 DFN1006 小封装,适合对空间和高度有限的移动设备、通信终端与精密电子模块的保护需求。

二、主要特性

  • 极性:双向,能够同时吸收正向和负向瞬态脉冲;
  • 反向截止电压 Vrwm:2.5 V,适配 2.5 V 级别信号或接口的持续工况;
  • 击穿电压:3.6 V(典型),启动导通以夹紧过冲电压;
  • 钳位电压:约 8 V(在指定脉冲条件下),对脉冲峰值有效限制;
  • 峰值脉冲电流 Ipp:8 A @ 8/20 µs;峰值脉冲功率 Ppp:60 W @ 8/20 µs;
  • 反向电流 Ir:200 nA,静态漏电小,对低功耗系统影响小;
  • 结电容 Cj:约 20 pF,适合高速信号线的保护需求;
  • 符合等级:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)与 IEC 61000-4-5(浪涌)测试等级要求。

三、电气参数解读

该器件 Vrwm 为 2.5 V,表示在正常工作条件下对 2.5 V 及以下信号线不导通;当出现高能瞬态时,器件在约 3.6 V 附近进入击穿并将电压钳位在约 8 V,借助最大 8 A 的 8/20 µs 脉冲承受能力快速吸收能量。200 nA 的低漏电和 20 pF 的低结电容使其在保护敏感高速信号(如某些低压接口与控制线)时既不会带来明显负载,也不会显著影响信号完整性。

四、典型应用场景

  • 2.5 V 电源与信号接口保护(低压通信接口、外设控制线);
  • 移动终端、消费电子、可穿戴设备中的端口与 I/O 防护;
  • 数据通信板卡、低压 ADC/DAC 前端的瞬态防护;
  • 工业控制模块中对低电平传感器线的 ESD/EFT/浪涌保护。

五、封装与布局建议

器件采用 DFN1006 小型封装,便于在密集 PCB 布局中靠近被保护引脚贴装。建议布局要点:

  • 将 TVS 器件尽量靠近被保护的接口或器件引脚放置;
  • 引脚到地的走线尽量短且宽,避免形成长回路;
  • 对地平面保持连通性,必要时在靠近器件处使用多层过孔快速引导到参考地;
  • 对高速差分或敏感信号,注意走线阻抗与结电容匹配,减少反射与带宽损失。

六、选型与使用注意事项

  • 确认被保护线路的最大持续电压不超过 Vrwm(2.5 V),否则器件会长期导通;
  • 根据系统可能遭遇的脉冲类型(ESD、EFT、浪涌)核对器件的能量吸收能力与 IEC 等级是否满足;
  • 在高能浪涌系统中,结合熔断器或串联阻抗使用以分担能量;
  • 在非常高速或超低电容敏感应用,评估 20 pF 是否满足系统带宽要求;若需更低电容,可考虑专用低容 TVS。

七、可靠性与合规

BDFN2C2R51V 针对 IEC 61000-4-2/4-4/4-5 的抗扰性能设计,通过相应试验可为产品提供 ESD、脉冲群和雷击/开关瞬态的保护能力。其低漏电和小封装特性也利于长期稳定工作于移动与低功耗系统中。

总结:BDFN2C2R51V 是一款面向 2.5 V 级低电压、高速信号保护场景的双向 TVS 器件,凭借 8 A/60 W 的瞬态吸收能力、低漏电与 20 pF 的低结电容,在体积受限且要求高抗扰性的应用中具有良好的性价比和实用性。

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.
