3.0SMCJ33CA_R1_00001 产品概述

一、产品简介

3.0SMCJ33CA_R1_00001 是 PANJIT(强茂)推出的一款双向瞬态电压抑制器(TVS),封装为 DO-214AB(SMC)。器件设计用于吸收电网浪涌与静电放电引起的高能瞬态,保护下游电子元件和电源系统。主要参数:反向截止电压 Vrwm = 33V,击穿电压 VBR = 42.2V,钳位电压 Vc = 53.3V(对应测试条件),峰值脉冲电流 Ipp = 56.2A(10/1000μs),峰值脉冲功率 Ppp = 3kW(10/1000μs),反向漏电流 Ir = 3μA,工作温度范围 -55℃~+150℃。

二、关键参数说明

  • 极性:双向(Bidirectional),适合交流或可能正负方向出现瞬态的线路,无极性方向要求。
  • Vrwm(33V):器件在该电压下可长期承受不触发钳位的直流工作电压,适配 24V 工业/车辆系统的抬高瞬态。
  • VBR(42.2V)与钳位电压 Vc(53.3V):当瞬态超过 VBR 时进入导通并限制电压至 Vc 附近,保护受保护线路。上述 Vc 为对应 Ipp 的测试测得值。
  • Ipp / Ppp(10/1000μs 波形):该器件在 10/1000μs 浪涌下能承受单次峰值电流 56.2A,等效脉冲能量为 3kW,适合高能雷击感应或电源浪涌缓冲场合。
  • Ir(3μA):在 Vrwm 下的静态漏电小,有利于低功耗系统。

三、封装与热管理

SMC(DO-214AB)为中功率表面贴装封装,具有良好的散热路径。实际应用中应尽量靠近可能受扰动的连接器或输入端放置 TVS,同时在焊盘设计中增大铜箔面积、添加热过孔或接地平铺,以利于脉冲能量分散与热耗散,避免反复高能脉冲导致器件过热。

四、典型应用场景

  • 工业 24V 电源和控制总线防护;
  • 车载电子与电源输入保护(需确认系统最大持续电压);
  • 通信电源与直流母线浪涌吸收;
  • 电源模块、逆变器输入端的雷击/浪涌抑制。

五、使用与布局建议

  • 将 TVS 放置在入线点或连接器附近,走线短且粗,减少寄生电感;
  • 对于高能或可能重复冲击的环境,配合串联熔断器或限流电阻使用,以防止器件在连续浪涌下损坏;
  • 注意保持器件两端良好接地,提供低阻抗回路;
  • 根据制造商焊接规范选择回流或波峰焊温度曲线,避免过热影响可靠性;
  • 若用于敏感信号线,确认双向特性与钳位电平对信号的影响。

六、可靠性与注意事项

器件工作温度范围宽(-55℃~+150℃),适合苛刻环境。尽管单次脉冲能力强,但不建议长期承受重复大能量冲击,必要时需进行脉冲能量管理与器件级联保护;使用前请参阅完整数据手册以获取浪涌测试条件、能量吸收曲线和寿命评估。采购时确认批次与温度系数要求,按实际系统余量选择合适 Vrwm 与钳位等级。

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
