SM8S10A TVS 瞬态电压抑制二极管 产品概述
一、产品概述
SM8S10A 是东沃（DOWO）推出的一款单向 TVS 瞬态抑制二极管，采用优化玻璃钝化芯片制造，设计用于保护车载和高可靠性电子负载免受瞬态过电压、浪涌和负载突降影响。器件在高温下具有稳定性能，工作温度范围为 -55℃ 至 +175℃，适合严苛环境应用。
二、主要参数
- 反向截止电压 Vrwm：10V
- 击穿电压 VBR：11.1V
- 钳位电压（典型）：17V
- 峰值脉冲电流 Ipp：388A（10/1000μs）
- 峰值脉冲功率 Ppp：6.6kW（10/1000μs，重复率/占空比 0.01%）
- 反向电流 Ir：15μA
- 极性：单向（unidirectional）
- 封装：DO-218AB
三、主要特性
- 优化玻璃钝化芯片，耐温性能优良，器件可承受 Tj 达 175℃。
- 极佳的钳位能力与极快响应时间，能有效限幅瞬态峰值，保护下游器件。
- 低泄漏电流与低正向压降，减小待机功耗与导通损耗。
- 满足汽车电气标准：ISO 7637-2（5a/5b）兼容，并通过 AEC-Q101 认证；可应对 ISO 16750 规定的负载突降测试（具体结果视测试条件而定）。
- RoHS 合规，适用于严格环保要求的产品线。
四、典型应用
- 汽车电子：车身控制模块、车灯、仪表、通信与车载信息娱乐系统等。
- 工业控制与电源模块：逆变器、驱动器、传感器接口、DC-DC 转换器输入侧保护。
- 通信设备与测试仪器的电源浪涌防护。
五、封装与可靠性
DO-218AB 封装提供良好的散热通道和机械强度，适合大电流脉冲场景。器件通过 AEC-Q101 认证并经过波峰/回流兼容处理，适合汽车级制造流程。玻璃钝化工艺提高了长期稳定性与抗湿热能力。
六、使用建议
- 推荐在电源轨或信号线上近源端布置以获得最佳保护效果。
- 对于连续或高频率的脉冲，应参考 Ppp、占空比与热阻参数，必要时配合散热或外部限流元件使用。
- 在设计中预留合适焊盘和散热区域，确保 DO-218AB 封装的热性能发挥。
SM8S10A 以其高能量承受能力、汽车级可靠性和低泄漏特性，适用于对瞬态保护要求苛刻的系统。若需具体电气特性曲线或封装尺寸图，请索取详细规格书。

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.
