BSD3C241V TVS二极管产品概述

BSD3C241V是伯恩半导体(BORN)推出的一款双向瞬态抑制二极管(TVS),专为低电压电路的ESD(静电放电)、EFT(电快速瞬变脉冲群)及Surge(浪涌)防护设计,凭借小体积封装、精准电气参数及国际标准兼容性,成为消费电子、便携设备及工业控制领域的常用防护器件。

一、产品核心定位与设计目标

作为ESD防护专用TVS,BSD3C241V的设计核心是在不干扰正常电路的前提下,快速抑制瞬态过压:

  • 针对12V/24V低电压系统优化,反向截止电压与击穿电压匹配常见工业/消费电子电平;
  • 采用超小型SOD-323封装,适配手机、智能穿戴等高密度PCB布局;
  • 满足IEC 61000系列EMC标准,确保复杂环境下的防护可靠性。

二、关键电气参数深度解析

BSD3C241V的参数精准匹配低电压防护需求,核心分为工作范围、防护能力、静态特性三类:

1. 工作电压范围

  • 反向截止电压(Vrwm):24V:正常工作时器件反向承受的最大直流/交流电压,电路电压≤24V时器件截止,不影响信号传输;
  • 击穿电压(Vbr):26.7V(典型值):瞬态过压超24V时快速击穿导通,击穿电压与Vrwm的差值(~2.7V)保证低漏电流。

2. 瞬态防护能力

  • 峰值脉冲电流(Ipp):5A@8/20μs:8/20μs是国际浪涌电流波形标准(模拟雷击、电源浪涌),可承受5A峰值脉冲;
  • 峰值脉冲功率(Ppp):300W@8/20μs:最大瞬态功率容量,未超300W时有效抑制过压;
  • 钳位电压(Vc):50V(典型值):击穿后将电路电压钳位在50V以内,远低于多数IC损坏阈值(30V~60V)。

3. 静态特性

  • 反向漏电流(Ir):500nA(最大值):漏电流极小,不增加电路功耗或信号失真;
  • 结电容(Cj):15pF(典型值):中等结电容,适配USB 2.0、UART等数字信号,高频RF电路需结合带宽评估。

三、封装与可靠性设计

1. 封装特性

采用SOD-323封装(1.6mm×0.8mm×0.8mm),具备:

  • 超小体积:适配手机、智能手表等便携设备高密度PCB;
  • 无引线设计:焊接可靠性高,避免引线断裂;
  • 表面贴装:适合自动化生产,降低组装成本。

2. 标准兼容性

通过多项国际EMC标准测试:

  • IEC 61000-4-2(ESD):应对人体接触(HBM)、机器接触(MM)等静电场景;
  • IEC 61000-4-4(EFT):抑制开关电源、电机启动产生的快速瞬变脉冲;
  • IEC 61000-4-5(Surge):抵御雷击、电源电压突变等浪涌干扰。

四、典型应用场景

BSD3C241V广泛应用于低电压电路防护:

  1. 消费电子接口:手机USB Type-C、平板HDMI、耳机音频接口的ESD防护;
  2. 便携设备:智能手表、运动相机的电源与信号端口防护;
  3. 工业控制:PLC低电压I/O口、传感器信号线路防护;
  4. 通信设备:路由器、交换机以太网端口、WiFi模块的ESD防护;
  5. 汽车电子:车载USB充电器、中控屏辅助电路防护(需结合汽车级认证)。

五、选型与使用注意事项

  1. 电压匹配:后端电路最大工作电压≤24V,避免Vrwm被突破;
  2. 脉冲能力匹配:超5A/300W时可多器件并联(注意结电容叠加);
  3. 焊接规范:焊接温度≤260℃,时间≤3秒,避免热损伤;
  4. 结电容评估:高频RF电路需确认15pF是否影响信号完整性,必要时选低结电容型号。

六、总结

BSD3C241V以精准参数、小体积封装及国际标准兼容性,成为低电压电路瞬态防护的优选器件。其平衡了“正常电路无干扰”与“瞬态过压快速抑制”,适配多领域防护需求,性价比突出。

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
