SM712-02HTG 产品概述
一、产品简介
SM712-02HTG 是 DOWO（东沃）推出的双路、双向瞬态抑制器（TVS）阵列，封装为 SOT-23，针对数据线和信号线的静电与浪涌保护而设计。器件工作温度范围为 -55℃ 至 +125℃，适合工业级与商用电子设备中对电磁兼容（EMC）和电气快速瞬变（EFT/Surge）防护有要求的场景。
二、典型参数
- 极性：双向
- 通道数：双路
- 反向截止电压 (Vrwm)：12V；7V（提供两种标称工作电压）
- 击穿电压 (Vbr)：13.3V（对应12V型号）；7.5V（对应7V型号）
- 钳位电压 (Vclamp)：26V；10V（对应不同型号或工作点）
- 峰值脉冲电流 (Ipp)：12A
- 峰值脉冲功率 (Ppp)：400W（单次 10/1000 µs 波形或典型测试条件）
- 反向电流 (Ir)：1 µA（典型）
- 结电容 (Cj)：75 pF（表征高频信号影响时的典型值）
- 防护等级：符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 标准
三、主要特点与优势
- 双向保护：支持双极性瞬态，适用于差分信号或双向数据线。
- 双路集成：SOT-23 封装内集成两路保护通道，节省 PCB 面积与成本。
- 宽温度范围：-55℃ 至 +125℃，适合恶劣环境和工业应用。
- 合规性高：满足 IEC-4-2/4-4/4-5 抗扰度测试要求，提升系统抗干扰能力。
- 低漏电与中等结电容：Ir 典型仅 1 µA，Cj≈75 pF，兼顾低泄漏与信号完整性需求。
四、封装与可靠性
SOT-23 小封装便于自动贴装与批量生产。器件在高温与冲击条件下表现稳定，推荐在热设计时考虑器件周边散热与焊盘过孔布局以降低热阻，提高浪涌吸收能力。
五、典型应用
- 通信接口与数据线防护（串行总线、差分对、I/O 端口）
- 工业控制与测量设备的输入保护
- 以太网端口、USB/串口等外围接口的瞬态抑制（视电压与电容限制）
- 消费电子与车载辅助电路中的局部防护
六、设计与布局建议
- 尽量将 SM712-02HTG 靠近被保护器件或接口放置，缩短保护器至受保护线的走线长度。
- 将器件的地引脚与系统地通过低阻抗回路连接，必要时使用多条地线或过孔改善回流路径。
- 对高速差分信号注意结电容对信号完整性的影响，Cj≈75 pF 在某些高速应用需评估是否满足带宽要求。
- 在高能量或长线入射的场合，可与串联阻抗或滤波器配合，提升系统整体防护性能。
七、采购与识别
型号：SM712-02HTG；品牌：DOWO（东沃）；封装：SOT-23。采购时请确认所需 Vrwm（7V 或 12V 版本）、参数一致性与原厂或授权分销渠道的可追溯性，以保证长期供应与品质稳定。

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.
