SMBJ60A NK — 产品概述
一、主要规格
SMBJ60A NK 为晶导微电子出品的 TVS 二极管，采用 SMB 封装，面向瞬态浪涌保护场合。关键参数如下：
- 反向截止电压 (Vrwm)：60 V
- 击穿电压 (Vbr)：73.7 V（典型）
- 钳位电压：96.8 V（在峰值脉冲电流下）
- 峰值脉冲电流 (Ipp)：6.2 A
- 峰值脉冲功率 (Ppp)：600 W（波形 10/1000 µs）
- 反向电流 (Ir)：1 µA（典型）
- 结电容 (Cj)：390 pF
- 工作温度范围：-65 ℃ ~ +150 ℃
- 器件类型：TVS，封装：SMB
二、特性亮点
SMBJ60A 提供高能量吸收能力（600 W@10/1000 µs）和较高的钳位水平（96.8 V），适用于对瞬态浪涌有较强抑制需求的中低压系统。低漏电（≈1 µA）有利于降低静态功耗。SMB 封装兼顾功率散热与 PCB 可装配性，便于自动化贴装与回流焊工艺。
三、典型应用场景
- 48 V 或 60 V 直流供电系统的浪涌保护（如通信基站、电源模块）
- 工业控制与自动化设备的输入/输出端口防护
- 电源线路、逆变器与电机驱动的脉冲抑制
注：结电容较大（390 pF），不建议用于对信号完整性要求高的高速数据或射频线路。
四、设计与选型建议
- 确认工作电压：Vrwm=60 V 适用于系统持续电压不超过 60 V 的场合。若系统存在更高工作电压，需选型更高 Vrwm 的器件。
- 考虑钳位能力：钳位电压约 96.8 V（在指定脉冲下），需判断被保护元件是否能承受该瞬态电压。
- 脉冲能量匹配：本器件对 10/1000 µs 波形下能量吸收能力强，适合工频雷击后续脉冲或开关转换引起的长时常冲击。
- 对于高速信号线或对低电容敏感的接口，应避免使用该型号，改用低电容 TVS。
五、安装与可靠性注意事项
- 推荐采用标准 SMB 封装焊盘，确保良好热散与机械支撑；回流焊曲线参考厂方数据手册。
- 在高能量场合，布线应尽量缩短到地的回路，增加散热铜箔以提升脉冲吸收能力。
- 存储与使用环境避免潮湿与腐蚀性气体，长期在高温高湿环境下会影响可靠性。
- 如需双向保护或特殊极性要求，请参考晶导微电子的完整数据手册以确认器件具体型号和极性属性。

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.
