SM8S11CA 产品概述
一、产品简介
SM8S11CA 为 DOWO（东沃）出品的双向瞬态电压抑制器（TVS），采用玻璃钝化芯片技术，封装为 DO-218AB。器件专为瞬态浪涌保护设计，能够在瞬态事件中迅速钳位，保护后续电路免受高能脉冲损害。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：11 V
- 击穿电压 VBR：12.2 V
- 钳位电压（典型）：18.2 V
- 峰值脉冲电流 Ipp（10/1000 μs）：363 A
- 峰值脉冲功率 Ppp（10/1000 μs）：6600 W
- 反向电流 Ir：≤10 μA（在 Vrwm 条件下）
- 波形与占空比：10/1000 μs, 重复率（占空比）0.01%
三、关键特性
SM8S11CA 的玻璃钝化芯片提供稳定的电气特性和优良的热稳定性；极快的响应时间确保在短暂电压尖峰出现时迅速钳位；低泄漏电流有利于在待机或低功耗电路中使用；优秀的钳位能力使得被保护电路承受的最大电压受控。
四、可靠性与合规
- 符合 ISO7637-2 中 5a 浪涌规范，适合汽车电气环境的瞬态冲击防护要求。
- 满足 AEC‑Q101 汽车级器件可靠性要求，适用于车载电子应用。
- 符合 RoHS 环保标准，支持无铅工艺及相关环保要求。
五、典型应用
适用于汽车电源线路、通信总线、传感器接口、车载控制单元（ECU）、工业控制设备及其它需要抑制大电流脉冲的场合。双向结构亦适合双极性信号线或交流线路的浪涌保护。
六、封装与安装建议
DO-218AB 封装便于散热与大电流吸收，建议在 PCB 设计中尽量缩短器件到被保护节点的连线并采用足够的铜厚和散热面积，以发挥最高峰值功率能力。遵循厂方焊接和回流曲线，可保证可靠性。
七、产品优势
结合高达 6600 W 的瞬态功率承受能力、低漏电、高速响应与汽车级认证，SM8S11CA 在车载及工业浪涌防护场景中提供可靠且经济的保护方案。
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.
