SM8S30CA 瞬态抑制二极管（双向 TVS）产品概述
一、产品简介
SM8S30CA 是 DOWO（东沃）推出的一款高能量吸收、双向瞬态电压抑制二极管，符合 AEC-Q101 汽车级可靠性规范，适用于汽车和工业环境中的瞬态浪涌保护。器件封装为 DO-218AB，结构稳健，便于散热与可靠焊接。
二、主要性能参数
- 极性：双向（可对称钳位正负方向脉冲）
- 反向截止电压 Vrwm：30 V
- 击穿电压 Vbr：33.3 V
- 钳位电压 Vc（Ipp）：48.4 V（在峰值脉冲电流条件下测得）
- 峰值脉冲电流 Ipp：136 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：6.6 kW（10/1000 μs）
- 反向漏电流 Ir：≤ 10 μA
- 类型：TVS（瞬态抑制二极管）
以上参数表明该器件在短时高能量冲击下具有良好钳位能力与较低漏电。
三、典型应用场景
- 汽车 12V/24V 总线与车载电子模块瞬态保护（符合 AEC-Q101 要求）
- 车载充电、逆变及电源输入口抗雷击、电刷回火抑制
- 工业电源、通信线路及敏感接口的浪涌防护
双向设计尤其适合需双向电压抑制的交流耦合或差分线路。
四、封装与热管理建议
DO-218AB 封装提供较大的散热路径和稳定机械支撑，有利于高能量吸收后快速散热。推荐在 PCB 布局中使用短、粗的回流路径连接到地/母线，并在可能的位置添加散热铜箔以提高热耗散能力。
五、可靠性与合规性
该器件通过 AEC-Q101 认证，表示其经受汽车环境高低温、振动、湿热等应力测试，适用于严苛车辆与工业环境。常规可靠性注意事项包括按推荐工艺焊接、避免长期在极限电压下工作以及遵循热循环要求。
六、选型与使用建议
- 确认最大工作电压 Vrwm 高于系统最大稳态电压，并留有裕量；
- 评估冲击能量与 10/1000 μs 标准能量是否匹配，必要时并联多只或选更高功率型号；
- 布局时尽量缩短保护器与被保护点之间的连线，避免旁路电感造成钳位效率降低；
- 焊接时遵循厂家温度曲线，避免长时间过热影响特性。
七、结语
SM8S30CA 以其 30 V 截止电压、136 A 峰值脉冲电流和 48.4 V 钳位能力，提供对汽车及工业电子设备的高效瞬态保护。结合 DO-218AB 封装和 AEC-Q101 级别可靠性，是需要大能量吸收与高可靠性场合的优选解决方案。若需样片、器件数据手册或应用参考图，请联系 DOWO（东沃）或授权分销商获取详细资料。

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.
