P6SMB6.8A 产品概述
一、产品简介
P6SMB6.8A 为单向瞬态抑制二极管（TVS），由东沃（DOWO）生产，封装为 SMB（DO-214AA）。器件针对电源线与信号线的浪涌、雷击和静电放电提供低阻的瞬态箝位保护，在高能脉冲情况下能快速导通并限制电压，保护下游元件免受过压破坏。
二、主要参数
- 钳位电压（Vc）：10.5V（典型）
- 击穿电压（Vbr）：6.45V
- 反向工作电压（Vrwm）：5.8V
- 峰值脉冲功率（Ppp）：600W @ 10/1000μs
- 峰值脉冲电流（Ipp）：58.1A
- 反向电流（Ir）：1mA（在 Vrwm 下）
- 极性：单向
- 工作温度：-65℃ ~ +150℃
- 封装：SMB (DO-214AA)
三、特性与优势
- 高能吸收能力：600W@10/1000μs 的脉冲功率，适合工业级浪涌防护。
- 低钳位电压：在大电流下仍能将电压控制在约10.5V，减小被保护器件应力。
- 宽工作温度：-65℃~+150℃，适应严苛环境温度变化。
- 单向结构：对直流偏置电路提供可靠保护，响应速度快。
四、典型应用
- 汽车电子电源防护（整车弱电总线、车载控制模块）
- 工业控制与电源输入端浪涌抑制
- 通信设备、基站及光纤收发器接口保护
- 消费类电源适配器与保护板、防静电通道
五、封装与可靠性
SMB（DO-214AA）封装便于自动贴装与回流焊接，具有良好热散能力。器件应遵循回流焊温度曲线与防潮等级要求，避免多次超高温重复焊接以维持可靠性。
六、使用建议与注意事项
- PCB 布局应尽量缩短器件到接地的回流路径，增加附近散热焊盘和过孔以提升能量散散。
- 在选型时确认浪涌波形（10/1000μs）与实际工况一致，若波形不同需按能量和电流做降额计算。
- 非持续导通设计，避免器件在短时大电流后继续承受长期电流。
- 注意反向漏电随温度上升增加，敏感电路应留有余量。
七、订购与质量保证
品牌：DOWO（东沃）。封装及参数适用于需要中高能量浪涌保护的场合。采购时请确认完整型号、批号及相关检验报告，必要时进行样片验证以确保与具体应用兼容。

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.
