BSD5A241V35 产品概述

一、概述

BSD5A241V35 是伯恩半导体(BORN)推出的一款单向瞬态抑制二极管(TVS),封装为超小型 SOD-523。该器件专为保护电子系统免受瞬态过压、雷击和静电放电等冲击而设计,符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)和 IEC 61000-4-5(Surge)等电磁兼容防护标准,适合空间受限的便携设备与工业接口保护应用。

二、主要电气参数(典型值)

  • 极性:单向
  • 反向截止电压(Vrwm):24 V
  • 击穿电压(Vbr):26.7 V
  • 钳位电压(Vclamp):45 V(在指定脉冲条件下)
  • 峰值脉冲电流(Ipp):5 A @ 8/20 µs
  • 峰值脉冲功率(Ppp):280 W @ 8/20 µs
  • 反向电流(Ir):500 nA(在 Vrwm 条件下,常温)
  • 结电容(Cj):30 pF
  • 封装:SOD-523
  • 型号:BSD5A241V35,品牌:BORN(伯恩半导体)

三、产品特点与优势

  • 抑制能力强:在 8/20 µs 测试条件下,单次脉冲电流可达 5A,能承受 280W 峰值脉冲功率,适合常见浪涌与雷击能量吸收。
  • 低漏电:反向漏电仅 500 nA(典型),对供电稳定性影响小,适合电源敏感电路。
  • 适配 24V 线路:24V Vrwm 使其可直接用于 24V 工业总线或汽车 24V 旁路保护(请确认器件是否满足车辆级认证要求)。
  • 小尺寸封装:SOD-523 适合高密度 PCB 布局与表面贴装自动化生产,节省空间。
  • 中等结电容(30 pF):在多数低速或中速信号应用中影响有限,但在极高速数据链路上需评估其对信号完整性的影响。

四、典型应用场景

  • 24V 工业控制总线、继电器驱动与传感器接口保护
  • 通信设备的接口与电源浪涌防护
  • 便携与消费类电子的外部连接器、充电口保护(空间受限场景)
  • 工业以太网、RS-485、CAN 等差分通信总线前端保护(注意评估结电容对信号带宽的影响)

五、使用建议与布局要点

  • 典型接法(单向):阴极接电源正(或信号线),阳极接地,待机电压不超过 Vrwm(24V)。
  • 布局:将 TVS 尽可能靠近受保护的外部接口或连接器放置,走线最短并尽量直接接入地平面,以减少感性阻抗和环路面积。
  • 热与可靠性:SOD-523 封装尺寸小,散热能力有限,长时间多次承受高能脉冲会产生热累积,应确保设计满足最大脉冲能量要求并考虑适当的冗余。
  • 信号完整性:30 pF 结电容对高速信号有一定影响,若用于高速接口(例如 >1 Gbit/s),建议进行时域仿真或选择低容型 TVS。

六、合规与选型提示

  • 本器件符合 IEC 61000-4-2/4-4/4-5 防护标准,适合常见的 ESD、EFT 与浪涌防护需求。
  • 选型时请注意系统的最大工作电压应 ≤ Vrwm(24V),且钳位电压(45V)需确保下游器件能承受该峰值电压。
  • 若用于汽车或更苛刻的工业环境,请在最终选型中确认是否需要额外的 AEC 或车规级认证件。

七、结语

BSD5A241V35 以小体积、较高的浪涌吸收能力和低漏电特性,为 24V 级别及类似应用场景提供了经济且有效的瞬态保护方案。设计时结合 PCB 布局、热管理和信号完整性评估,可在保证保护性能的同时最小化对系统的影响。若需器件封装尺寸图、最大额定值或焊接工艺建议,请参考厂方数据手册或联系供应商获取详细资料。

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
