SM8S24CA 产品概述
一、概述
SM8S24CA 是东沃（DOWO）推出的一款高能量双向瞬态抑制二极管（TVS），采用玻璃钝化芯片工艺，封装为 DO-218AB。器件专为汽车与工业电源线上强脉冲浪涌保护设计，能够在 10/1000 μs 波形下承受 6600 W 峰值脉冲功率（占空比 0.01%），并符合 ISO7637-2 第 5a 类浪涌规范及 AEC-Q101 可靠性要求。
二、主要参数（典型值）
- 极性：双向
- 反向截止电压 Vrwm：24 V
- 钳位电压 Vcl：38.9 V
- 击穿电压 VBR：26.7 V
- 峰值脉冲电流 Ipp：170 A（10/1000 μs）
- 峰值脉冲功率 Ppp：6.6 kW（10/1000 μs，0.01% 占空比）
- 反向电流 Ir：10 μA
- 工作温度范围：-55 ℃ ~ +175 ℃
- 封装：DO-218AB（高能量塑封）
三、产品特性
- 玻璃钝化芯片，增强长期稳定性与电气一致性。
- 极低泄漏电流，减少待机能耗与误触发。
- 极佳钳位能力，能在高能脉冲下保持受控电压，保护下游器件。
- 响应速度非常快，可有效钳制瞬态过电压。
- 通过 AEC-Q101 验证，适合汽车环境；符合 RoHS 环保要求。
- 满足 ISO7637-2 5a 浪涌测试规范，适用车载脉冲抗扰度要求。
四、典型应用场景
- 汽车电源与通信总线（例如车身控制模块、CAN/LIN 接口）
- 动力管理与电源供应系统的浪涌保护
- 工业自动化设备、传感器与执行器保护
- 电信基站与电源线防雷防浪涌应用
五、安装与使用建议
- 推荐并联布局或就近放置于需保护的电源输入端，以缩短保护路径与降低回路电感。
- DO-218AB 大功率封装需保证良好散热，引脚与 PCB 热铜箔建议加宽并连接到地平面以提升热耗散能力。
- 在高频或长线场合，配合串联电感或抑制电容可优化系统抗扰度。
- 工作环境温度接近上限时，应关注脉冲重复率与热累积，避免超出可靠工作范围。
六、可靠性与合规
SM8S24CA 通过 AEC-Q101 标准认证并满足 ISO7637-2 的汽车浪涌规范，器件设计与封装适合汽车级与严苛工业环境，长期工作温度范围宽（-55~+175 ℃），并符合 RoHS 环保要求。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
