BESDCAN24-2BLY 产品概述
一、产品简介
BESDCAN24-2BLY 是 BORN（伯恩半导体）推出的一款双向硅雪崩瞬态抑制二极管（TVS），专为差分数据线与工业接口的浪涌和静电保护设计。器件采用 SOT-23 小封装，适合空间受限的板级防护方案。
二、主要电气参数
- 反向工作电压 Vrwm：24 V（双向）
- 击穿电压 VBR：30 V
- 钳位电压（典型）：55 V
- 峰值脉冲电流 Ipp：6 A（8/20 μs）
- 峰值脉冲功率 Ppp：280 W（8/20 μs）
- 反向漏电流 Ir：500 nA（典型）
- 结电容 Cj：12 pF
- 符合标准：IEC 61000-4-2（±30 kV 接触/空气）、IEC 61000-4-4、IEC 61000-4-5
三、特点与优势
- 固态硅雪崩工艺，响应快、寿命长；
- 双向设计，可直接用于差分信号对（如 CAN 总线）或双向数据线；
- 低钳位电压，减小被保护器件承受的过压冲击；
- 低泄漏电流与较小结电容（12 pF），对高速信号干扰小；
- 高峰值功率与脉冲电流能力，满足雷击与浪涌冲击要求。
四、典型应用
- 汽车与工业现场的 CAN 总线、LIN 总线或以太网数据线保护；
- ATM 自动取款机、POS 终端等金融终端的数据接口防护；
- 各类通信接口、传感器线缆入口与外部连接器级防护。
五、封装与布板建议
SOT-23 小封装，尺寸便于自动贴装。推荐将器件靠近信号输入端或连接器放置，走线短且宽，尽量减小串联电感；接地回流路径要短且阻抗低，使用宽地铜箔和直通孔以提高浪涌能量承受能力。
六、选型与注意事项
选择时确认系统最大工作电压与被保护线的信号最高电压不超过 Vrwm。对高速差分线，应考虑结电容对信号完整性的影响（12 pF 为参考值）；在高能浪涌环境下，可并联隔离元件或阻尼网络以分担能量。
七、可靠性与标准
器件通过 IEC 61000-4-2/4-4/4-5 等电磁兼容（EMC）测试，适合要求较高的工业与汽车电子防护场合。支持自动化贴装，适用批量生产与维修替换。
BESDCAN24-2BLY 提供了在狭小空间内对差分数据线进行高效防护的解决方案，兼顾高速信号完整性与耐浪涌能力，适用于 ATM、工业通信与汽车电子等场景。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
