SMBJ70A 瞬态抑制二极管（TVS）产品概述
一、产品简介
SMBJ70A 是 BORN（伯恩半导体）出品的一款单向瞬态电压抑制二极管（TVS），采用 DO-214AA（SMB）封装，专为抑制电源和信号线上的瞬态过电压、浪涌和雷击脉冲设计。该器件在 10/1000μs 浪涌波形下可提供高达 600W 的峰值脉冲功率，适合工业电源、通信设备和一般电子设备的浪涌保护应用。
二、主要电气参数
- 钳位电压（VC）：113V（在 Ipp 条件下）
- 工作温度范围：-55℃ ~ +150℃
- 击穿电压（Vbr）：86V
- 反向截止电压（Vrwm，额定工作电压）：70V
- 峰值脉冲功率（Ppp）：600W @ 10/1000μs
- 峰值脉冲电流（Ipp）：5.3A（对应 Ppp 条件）
- 反向电流（Ir）：≤1μA（在 Vrwm 条件下典型）
- 极性：单向
三、产品特性
- 高能量吸收能力：在 10/1000μs 波形下可承受 600W 峰值脉冲功率，能有效吸收工业和雷击类浪涌。
- 低钳位电压：在规定峰值电流下钳位电压为 113V，可在较低电压水平将过电压限制在安全范围内，保护下游元件。
- 低漏电流：在额定工作电压下反向漏电流仅 1μA 级别，有利于低功耗系统。
- 宽温区可靠工作：-55℃ 至 +150℃ 的工作温度范围，适应恶劣环境与高温工况。
- 便于安装：SMB 封装适配常见的表面贴装或通孔过孔焊接布局，便于批量生产和更换。
四、典型应用领域
- 工业电源和控制系统的输入浪涌保护
- 通信基站、交换设备和路由器的电源防护
- 电机驱动、电源模块与逆变器的过压抑制
- 仪器仪表与测试设备的瞬态保护
（若需双向保护场合，请选用相应的双向 TVS 器件。）
五、使用建议与布板要点
- 保护器件应尽量靠近电源入口或受保护器件，缩短连接导线/走线以降低感性电压升高。
- 保证焊盘与散热路径的良好接触，必要时增加铜箔面积以利于热量扩散。
- 在高频或长距离布线场合，配合串联阻抗或 RC 滤波网络使用，可提升整体浪涌抑制性能。
- 在选择器件时注意钳位电压对下游器件耐压的影响，留足安全裕量。
六、注意事项
- 请确认工作电压不超过 Vrwm（70V），超出该值器件将进入击穿并持续导通。
- 本器件为单向型，在交流或需双向抑制的场合不可直接替代。
- 对于需要车辆级认证或特定行业资质的项目，请向供应商确认相关认证或选型替代件。
七、封装与订购信息
- 封装：DO-214AA（SMB）
- 品牌：BORN（伯恩半导体）
- 型号示例：SMBJ70A（单向，70V Vrwm）

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.
