SMBJ16CA (SMB,DO-214AA) 16V 双向 TVS 二极管 — 产品概述

一、产品简介

SMBJ16CA 是一款针对瞬态过电压和浪涌保护设计的双向瞬态电压抑制器(TVS)二极管,封装为 SMB(DO-214AA),品牌 MDD。器件在瞬态冲击(10/1000µs 波形)条件下能承受较高能量吸收能力,适用于各种工业、通信和电源线的浪涌保护场景。器件工作温度范围宽(-65℃ 至 +150℃),适应恶劣环境下长期可靠运行。

二、主要参数

  • 极性:双向(双向钳位,适用于正/负脉冲保护)
  • 反向截止电压(Vrwm):16 V(稳压工作电压)
  • 击穿电压(Vbr):19.7 V(典型)
  • 钳位电压(Vclamp):26 V(在指定测试条件下)
  • 峰值脉冲电流(Ipp):23.1 A @ 10/1000 µs
  • 峰值脉冲功率(Ppp):600 W @ 10/1000 µs
  • 反向电流(Ir):1 µA(在 Vrwm 条件下的泄漏电流)
  • 工作温度范围:-65 ℃ 至 +150 ℃
  • 类型:TVS 二极管
  • 封装:SMB(DO-214AA)
  • 品牌:MDD
    (以上参数为典型/额定值,具体应用时请参考完整数据手册。)

三、产品特性与优势

  • 高能量吸收:在 10/1000 µs 浪涌测试条件下,器件能承受 600 W 峰值功率和 23.1 A 峰值脉冲电流,适合电源线路和长距离传输线的雷击及开关瞬变防护。
  • 双向保护:能同时抑制正负方向瞬变,适用于交流线路、差分信号或可能出现反向瞬变的应用场合,无需区分极性安装。
  • 低漏电流:在 Vrwm 下反向电流典型为 1 µA,有助于降低静态功耗,适合对待机功耗敏感的电路。
  • 宽工作温度:-65 ℃ 至 +150 ℃ 的温度范围保证在极端环境条件下仍能可靠工作,符合工业级/汽车级温度要求(具体认证以厂方数据为准)。
  • SMB 封装:中等功率/散热能力与易于波峰/回流焊接的封装,便于 PCB 布局与量产。

四、典型应用场景

  • 电源轨过压保护:保护 12V/15V 等直流电源轨免遭瞬态浪涌破坏。
  • 通信设备:保护调制解调器、路由器、交换机等端口免受雷击或线路浪涌影响。
  • 工业控制:PLC、驱动器和现场总线设备的电源与信号保护。
  • 汽车电子(视认证):用于车载子系统的瞬态抑制(需核对是否符合汽车 AEC 标准)。
  • 电池和充电系统:为充电线路和开关元件提供瞬态保护。

五、使用建议与可靠性注意事项

  • PCB 布局:保护器件应尽可能靠近被保护对象(连接端或电源入口),引线或走线要短且宽,以减少阻抗和回路面积,提高钳位效率与散热。
  • 热管理:在高能量冲击条件下器件会发热,确保周边有足够的铜箔散热面积或考虑散热措施以免过热影响可靠性。
  • 串联阻抗:对高次谐波或重复脉冲场景,适当增加串联阻抗或使用级联保护可降低单个器件承受的应力。
  • 安装与焊接:遵循封装的回流焊温度曲线和时限规范,避免过高温度或长时间滞留导致器件性能下降。
  • 验证测试:在最终系统中应进行浪涌和 ESD 验证,确认钳位电压和剩余电压满足后端器件的承受能力。

六、封装与订购信息

  • 封装形式:SMB(DO-214AA),适合自动贴装与回流焊接工艺。
  • 型号标识:SMBJ16CA(MDD)— 在采购时建议确认包装单位、生产批号和完整数据表,必要时要求出厂测试报告。
  • 兼容性:本器件遵循行业 SMBJ 型 TVS 规范,替换或并联使用时请核对 Vrwm、Vbr、Vclamp、Ipp 等关键参数以确保功能匹配。

总结:SMBJ16CA 为中等功率、双向保护的 TVS 器件,凭借 16V 工作电压、26V 钳位电压及 600W 的瞬态承受能力,适用于多种电源和信号浪涌防护场景。在布局、热管理和验证测试上采取合适措施,可显著提升系统在雷击与开关瞬变下的可靠性。若需完整电气特性曲线或封装图纸,请索取 MDD 官方数据手册。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
