SMBJ8.0CA 产品概述
一、产品概述
SMBJ8.0CA 是 DOWO（东沃）推出的一款双向瞬态抑制二极管（TVS），封装为 SMB (DO-214AA)。该器件专为保护 8V 等级电源和信号线免受雷击、开关瞬变及静电放电等冲击而设计，能够在短时脉冲事件中吸收高能量，保护下游敏感元件不被破坏。
二、主要参数
- 钳位电压（Vc）：13.6V（典型）
- 击穿电压（Vbr）：8.89V
- 反向截止电压（Vrwm，工作电压）：8V
- 峰值脉冲功率（Ppp）：600W @ 10/1000μs
- 峰值脉冲电流（Ipp）：44.12A
- 反向电流（Ir）：≤50μA（在 Vrwm 下）
- 极性：双向（Bidirectional）
- 类型：TVS，封装 SMB (DO-214AA)
三、主要性能与特点
- 高能量吸收能力：在 10/1000μs 的脉冲条件下可承受 600W 峰值能量，适合较宽脉冲宽度的浪涌防护。
- 双向保护：对正负方向瞬态均能抑制，适用于交流或双向浪涌场景。
- 低漏电流：Vrwm 下漏电流仅 50μA，适合对静态功耗敏感的电路。
- SMB 封装：热性能和散热能力良好，适合 PCB 表面贴装与自动化生产。
四、典型应用场景
- 汽车电子 8V 级总线、车载传感器与控制模块的瞬态保护。
- 工业控制、PLC 与驱动器的电源及信号线防护。
- 通信设备、基站及交换设备的接口浪涌抑制。
- 消费电子、充电设备、LED 电源等对 8V 级保护需求的场合。
五、使用与布局建议
- 尽量将 TVS 器件靠近被保护端口或接口布置，连接线短且宽，以降低寄生电感和阻抗。
- 在高能量环境下建议与熔断器或限流电阻配合使用，以避免器件多次大能量冲击后的失效。
- 注意器件的热管理，结合 PCB 铜箔散热或散热岛设计，必要时并行多个 TVS 分担能量。
- 双向器件适合无极性线路；若为直流单方向线路，可考虑单向 TVS 获得更低钳位电压。
六、包装与订购信息
品牌：DOWO（东沃）；封装：SMB (DO-214AA)；型号推荐标识：SMBJ8.0CA。订购时请确认是否满足所需的脉冲测试条件（10/1000μs）与实际应用工作电压，并向供应商索取详细数据手册以获得完整的电气特性与可靠性信息。

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.
