SM24CANA-02HTG 产品概述
一、产品简介
SM24CANA-02HTG 是 KUU 品牌的一款双路双向瞬态电压抑制器（TVS），封装为 SOT-23，面向对抗静电放电（ESD）和脉冲干扰的保护需求。其反向截止电压（Vrwm）为 24V，击穿电压（VBR）26.7V，钳位电压典型值 52V，能在突发过压时快速夹断，保护敏感器件不被损坏。
二、主要电气参数
- 极性：双向（可对差分线或交流/可反向信号线保护）
- 反向截止电压 Vrwm：24V
- 击穿电压 VBR：26.7V
- 钳位电压：52V（典型）
- 峰值脉冲电流 Ipp：7A（行业常用脉冲条件下测得）
- 峰值脉冲功率 Ppp：350W
- 反向漏电流 Ir：1µA（温度与电压条件下）
- 结电容 Cj：50pF（每通道）
- 通道数：双路（两通道独立）
- 工作温度范围：-55℃ ～ +150℃
- 防护等级/符合标准：IEC 61000-4-2（ESD）、IEC 61000-4-4（EFT）
三、特点与优势
- 小体积封装（SOT-23），便于表贴、节省 PCB 面积并支持自动化贴片生产。
- 双路独立、双向工作，适合差分信号线或双方向信号保护，如 CAN、RS-485、串口数据线等。
- 低漏电流（1µA），对电池供电或低功耗系统影响小。
- 工作温度范围宽（-55～150℃），适应工业级应用环境。
- 符合 IEC ESD/EFT 标准，具备系统级电磁兼容性设计要求的保护能力。
四、应用场景与注意事项
- 典型应用：工业控制接口、通信端口（如 CAN、RS-485）、电源线防护、消费类电子外接接口、仪表与测量设备入口防护。
- 结电容为 50pF，对高频高速信号（如 USB3.0、HDMI、超高速差分链路）可能影响信号完整性，选型时需评估对带宽的影响；对中低速或模拟信号线、开关电源与电源轨保护非常适合。
- 选用时确认工作电压不超过 Vrwm（24V），长期工作电压接近或超过 Vrwm 会导致器件进入击穿区并产生热量或失效。
五、布局与安装建议
- 将器件尽量靠近受保护端口或连接器放置，保护回路短且接地牢靠。
- 对地的地线尽量使用低阻抗大面积地平面并配合过孔，引出至系统主地，减少回路电感。
- SOT-23 封装在波峰/回流焊下可按常规贴片工艺安装，注意焊盘尺寸和热沉设计以利于热量散发。
- 对于高能量脉冲（如雷击/直击浪涌）应在系统层面配合熔断/限流元件增加保护。
六、选型与采购信息
型号：SM24CANA-02HTG；品牌：KUU；封装：SOT-23；类型：ESD（双路双向 TVS）。选型时请对照系统峰值能量要求、工作电压与带宽需求，必要时与供应商确认脉冲测试条件与认证等级。

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.
