SMBJ16A/TR13 产品概述

一、产品简介

SMBJ16A/TR13 是台湾君耀(Brightking)生产的一款单向瞬态电压抑制二极管(TVS),用于抑制电源线和信号线的瞬态过电压。器件设计用于在高能量脉冲事件(如雷击、电源突变、静电放电)时快速钳制电压,保护下游器件免受损坏。

二、主要技术参数

  • 极性:单向(Unidirectional)
  • 反向工作电压 Vrwm:16 V
  • 击穿电压(典型):17.8 V
  • 钳位电压 Vc(峰值):26 V
  • 峰值脉冲电流 Ipp:23.1 A
  • 峰值脉冲功率 Ppp:600 W
  • 反向漏电流 Ir:≤1 μA(常温)
  • 工作温度范围:-65 ℃ ~ +150 ℃
  • 类型:TVS 二极管(瞬态抑制)
  • 封装:SMB(DO-214AA)
  • 包装:TR13(13英寸卷带,便于贴片生产线使用)

三、关键特性与优势

  • 高能量吸收:600 W 峰值脉冲功率与 23.1 A 的峰值脉冲电流,能有效处理大能量瞬态脉冲。
  • 低漏电流:≤1 μA 的反向电流,满足对待机功耗和高阻抗信号路径的要求。
  • 宽温度范围:-65 ℃ 至 +150 ℃,适应苛刻环境与工业级应用。
  • 单向结构:在常见的正向浪涌场景下提供低钳位电压,保护效率高。
  • 标准 SMB 封装:良好的散热性能,适合自动化贴片与重载应用。

四、典型应用场景

  • 工业电源与控制系统的输入保护(DC 24V/12V 电源线)。
  • 通信设备、电源适配器、逆变器的浪涌抑制与端口保护。
  • 汽车电子(非直接车身关键件,需满足AEC-Q标准时另行确认)。
  • 储能/太阳能系统的局部防护与设备接口保护。
  • 消费电子与仪表的电源与信号线保护。

五、封装与包装信息

SMB(DO-214AA)封装提供较好的热阻与机械强度,适合在有较大能量吸收需求的PCB区域使用。TR13 卷带包装方便SMT机台直接贴装,利于批量生产。

六、选型与使用建议

  • 若电路工作电压(最大连续电压)接近或高于 Vrwm(16 V),应选择更高 Vrwm 的型号以避免常态击穿。
  • 钳位电压 26 V 是在规定脉冲下的峰值,应结合被保护器件耐压评估是否足够。
  • 对于关键线路,建议配合熔断器/电感/串阻等元件形成多级保护,降低重复冲击风险。
  • 注意布局:TVS 应尽量靠近可能受击的连接点或外部接口,且接地回路要短、粗。

七、可靠性与环境适应

器件工作温度覆盖-65~+150 ℃,适合工业级和恶劣环境。为确保长期可靠性,推荐在实际应用中对浪涌承受能力与重复冲击寿命进行验证测试。

八、注意事项

  • 在高功率脉冲事件下,封装会产生热量,设计时需考虑散热与热隔离。
  • 单向 TVS 在反向极性连接(负向发生)时不能提供对称保护,特殊场景请选用双向型号。
  • 若用于汽车或航空等高可靠性领域,请确认是否满足相关认证与可靠性试验要求。

如需样品、详细电气特性曲线或PCB布局参考图,可进一步提供具体应用电压和保护需求,以便推荐更合适的保护策略与等效型号。

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.

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
