CDSOT23-T24CAN-Q 产品概述
一、产品简介
CDSOT23-T24CAN-Q 是 BOURNS 面向 24V 差分总线（如 CAN）和工业/汽车接口保护设计的双路 TVS 二极管，封装为 SOT-23-3。器件用于抑制瞬态过压和静电放电事件，有效保护收发器和敏感电子元件，适合在汽车、工业控制及通信接口中使用。
二、主要性能
- 反向截止电压（Vrwm）：24 V，适配典型 24V 总线工作电平。
- 击穿电压（VBR，Itest）：26.2 V（典型），保证在过压状态下启动箝位。
- 钳位电压：40 V（典型，受测试条件影响），在峰值脉冲下限制电压尖峰。
- 峰值脉冲电流（Ipp）：8 A @ 8/20 μs，具备良好浪涌承受能力（IEC 61000-4-5）。
- 反向漏电流（Ir）：100 nA（典型），维持低静态功耗。
- 通道结电容（Cj）：两个通道典型值分别为 22 pF 与 11 pF，便于高速信号匹配。
- 通道数：双路，SOT-23-3 小封装节省 PCB 面积。
- 工作温度：-40 ℃ ~ +150 ℃，满足车规及工业级应用温度要求。
- 符合 IEC 61000-4-2（ESD）与 IEC 61000-4-5（浪涌）防护等级。
三、典型应用场景
- 汽车 CAN 总线接口保护与收发器防护。
- 工业现场总线差分信号保护（如 RS-485 等类似拓扑）。
- 电源线路与数据线的瞬态抑制与 ESD 保护。
- 通信模块、传感器接口、控制器局部防护电路。
四、封装与引脚说明
SOT-23-3 小封装，便于高密度 PCB 布局。双路配置可实现两条信号线的独立或共阴（共阳）保护，具体引脚功能请参照器件数据手册（IN/OUT/GND 或两信号/地）。SOT-23-3 适合自动贴装与回流焊工艺。
五、选型与使用建议
- 在选择时确认 Vrwm 与系统工作电压匹配（24 V 系统优选 Vrwm=24 V）。
- 关注结电容对差分信号带宽的影响，若对高速信号敏感，优选低 Cj 通道或并联匹配网络。
- 布局时将 TVS 靠近被保护器件或连接点，地回路短且低阻抗，减少箝位回路电感。
- 对于长线或高能量冲击场合，评估是否需要并联更高能量级别的浪涌保护器件。
六、可靠性与合规
器件工作温度范围宽，具备车规级温度耐受性，并通过 IEC 61000-4-2/4-5 等静电与浪涌测试验证。建议在设计验证阶段根据实际系统能量级别进行场景测试（ESD、浪涌、振动、热循环等）。
七、封装与焊接建议
推荐采用标准 SOT-23-3 PCB 焊盘布局并使用符合 JEDEC/IPC 的回流焊工艺。储存与装配过程中按 ESD 防护规范操作，避免器件在未接地环境下受静电损伤。

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.
