CDSOD323-T24SC 产品概述
一、产品简介
CDSOD323-T24SC 是由 ElecSuper（静芯微）推出的一款单路双向瞬态电压抑制器（TVS），采用 SOD-323 小型封装，设计用于保护敏感电子线路免受雷击、静电放电（ESD）以及其它瞬态过压的损害。器件具有低漏电、快速响应和较低结电容，适合空间受限且要求信号完整性的应用场景。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：24 V
- 击穿电压（Vbr）：28 V
- 钳位电压（Vclamp）：42 V（典型）
- 峰值脉冲电流 Ipp：8 A @ 8/20 μs
- 峰值脉冲功率 Ppp：350 W @ 8/20 μs
- 反向电流 Ir：100 nA（常温条件）
- 结电容 Cj：18 pF
- 通道数：单路
- 工作温度范围：-40 ℃ ~ +125 ℃
- 防护等级：符合 IEC 61000-4-2（ESD）标准
三、关键特性
- 双向保护，适用于交流耦合或双向信号线的瞬态抑制。
- 高能量吸收能力：Ppp 350 W（8/20 μs），可承受短时大能量脉冲。
- 低泄漏电流（Ir ≈ 100 nA），对待机功耗影响极小。
- 低结电容（18 pF），有利于保持高速数据线和模拟信号的完整性。
- SOD-323 封装，适合表面贴装工艺和高密度 PCB 布局。
四、典型应用
- 工业与汽车 24 V 供电线保护（适配车载电子、工业控制模块等）。
- 通信接口与信号线防护（如 CAN、RS-485、UART 等双向线路）。
- 消费电子与便携设备的充电/数据接口保护。
- 网络设备与电源模块的瞬态抑制与浪涌保护。
五、封装与可靠性说明
CDSOD323-T24SC 采用 SOD-323 表面贴装封装，体积小、重量轻，适合自动贴装与回流焊工艺。器件额定工作温度为 -40 ℃ 至 +125 ℃，可满足多数商用与工业环境的可靠性要求。符合 IEC 61000-4-2 的 ESD 抗扰标准，能有效缓解静电导致的故障风险。
六、使用建议与选型要点
- 若应用电路为单向电源线，请确认是否需双向器件；双向器件在交流或可反向电压场合更为合适。
- 确认系统最大工作电压不超过 Vrwm（24 V），以避免常态下触发保护。
- 对于高速差分信号或对电容敏感的接口，18 pF 的结电容提供了较好平衡，但高频敏感应用应做实测验证。
- 在 PCB 布局中应将 TVS 靠近被保护端口放置，并优化接地回路以提高抑制效果。

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.
