SMBJ16A 产品概述
一、产品简介
SMBJ16A 为 BORN（伯恩半导体）出品的一款单向 TVS（二极管瞬态抑制器），封装为 DO-214AA（SMB）。主要用于瞬态浪涌和静电放电（ESD）保护，适配需要 16V 反向额定电压的电源或信号线。关键参数：反向截止电压 Vrwm = 16V，击穿电压 Vbr ≈ 19.7V，钳位电压 Vc ≈ 26V（在 10/1000μs 波形下），峰值脉冲电流 Ipp = 23.1A@10/1000μs，峰值脉冲功率 Ppp = 600W@10/1000μs，反向电流 Ir = 1μA（典型）。
二、主要性能特点
- 单向结构，针对正向突发过压进行低压钳位保护；
- 高能量吸收能力：Ppp = 600W（10/1000μs），适合工业和通信类浪涌事件；
- 低漏电流（Ir ≈ 1μA），在静态条件下对系统负载干扰小；
- 封装 DO-214AA（SMB），便于自动贴片和波峰/回流焊接工艺。
三、典型应用场景
- 电源输入端防护（12V~16V 类供电系统）；
- 通信接口、防雷浪涌保护（网口、电源线、串行总线）；
- 工业自动化设备、仪表、消费电子的浪涌与静电保护。
四、PCB 布局与使用建议
- 将 TVS 尽量靠近可能受冲击的连接器或器件放置，走短、粗的接线以降低寄生阻抗和电感；
- 为了散热与能量传导，保证焊盘完整且与铜箔有良好热连接；
- 在高能冲击环境下，考虑在 TVS 前端加入限流元件（如熔断器或阻性限流）以保护器件不被过度重复冲击；
- 选用合适回流焊温度曲线并遵循封装厂家推荐的焊接参数，避免过热损伤。
五、选型与注意事项
- 反向额定电压 Vrwm（16V）应高于系统正常工作电压且留有裕量；击穿电压（约 19.7V）高于 Vrwm，是正常工作范畴；
- 钳位电压 26V 是在指定脉冲下的典型值，实际系统中钳位效果与脉冲宽度、线路阻抗相关；
- 对于频繁的高能脉冲或持续高温环境，应评估热耗散与寿命；
- 检查封装尺寸、脚距以匹配 PCB 布局与自动化装配要求。
六、封装与订购信息
型号：SMBJ16A；品牌：BORN（伯恩半导体）；封装：DO-214AA（SMB）。适用于需要 16V 反向额定保护且要求高能量吸收能力的场合。如需样品、电气完整规范书或封装图，请向供应商索取详细数据手册以确认焊接、机械尺寸和极性标记等信息。

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.
