SMDJ33CA/TR13 产品概述

一、产品简介

SMDJ33CA/TR13 为台湾 Brightking(君耀)出品的双向瞬态电压抑制器(TVS),采用SMC(DO-214AB)封装。器件设计用于吸收和钳位线路上的瞬态冲击能量,保护敏感电子元件免受雷击、开关瞬变及电磁干扰引起的过压损害。器件可在宽温度范围内长期工作,适合工业与通讯类系统的浪涌防护需求。

二、主要电气参数

  • 类型:TVS,双向(Bidirectional)
  • 反向截止电压 Vrwm:33 V
  • 击穿电压(Vbr):36.7 V
  • 钳位电压(Vc,典型):53.3 V(在峰值脉冲电流条件下测得)
  • 峰值脉冲功率 Ppp:3 kW
  • 峰值脉冲电流 Ipp:56.3 A
  • 反向漏电流 Ir:2 μA(在 Vrwm 条件下)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 封装:SMC (DO-214AB)
    这些参数表明该器件在承受大能量瞬态脉冲时具有稳定的钳位能力和较低的漏流,适用于较高工作电压等级的防护场合。

三、主要特点

  • 高脉冲功率吸收能力:3 kW 峰值脉冲功率,可应对较强的瞬态冲击。
  • 有效钳位:在规定脉冲电流下,钳位电压约 53.3 V,可将过压限制在可接受范围内,保护下游器件。
  • 宽温度工作区间:-55 ℃ 至 +150 ℃,适合严苛环境和高温应用。
  • 低静态漏电:Vrwm 下漏电约 2 μA,有利于电源效率和待机功耗控制。
  • 双向保护:适用于交流或可正负切换的线路保护场景。

四、典型应用场景

  • 工业控制与电源输入防护(如直流母线保护、逆变器辅助保护)
  • 通信设备的线路保护(如基站、光纤收发端口的过压保护)
  • 电力与能源设备的浪涌防护(配电柜、监控设备输入端)
  • 其它需承受高能瞬态冲击的电子系统

五、封装与布局建议

  • 封装为SMC(DO-214AB),适合波峰/回流焊工艺;焊接时遵循厂商推荐的焊接温度曲线以保证可靠性。
  • PCB 布局应将 TVS 器件尽量靠近需保护的输入端或连接点,减少走线阻抗与寄生电感,以提高钳位效率。
  • 对于高能量脉冲,建议在器件附近增加铜箔和散热过孔以改善热散逸,避免器件局部过热。
  • 如需并联提升能量吸收能力,应遵循对称布局并注意各器件间电流分配问题。

六、使用与可靠性提示

  • 确认应用中的最大脉冲电流及能量密度不得超过器件额定值 Ppp 与 Ipp;频繁或连续的大能量冲击会降低器件寿命。
  • 对于关键应用,建议在最终系统环境(温度、频率、波形)下进行实际浪涌试验验证。
  • 存放与使用时避免长期高温、高湿环境,焊后应进行适当的清洗与干燥处理以防腐蚀。

七、结论与选型建议

SMDJ33CA/TR13 提供较高的瞬态吸收能力与宽温度适应性,适合需要在较高工作电压(Vrwm=33V)下进行稳健浪涌保护的工业与通信应用。选型时请核实系统最大脉冲能量、钳位电压容忍度及封装兼容性,必要时与 Brightking 技术资料对比具体测试条件和典型浪涌波形以确保匹配。

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
