1.5SMCJ30CA_R1_00001 瞬态抑制二极管(TVS)产品概述

一、产品基本信息与核心标识

该器件为PANJIT(强茂) 推出的双向瞬态抑制二极管(TVS),兼具静电放电(ESD)与浪涌保护功能,是低压系统过压防护的常用元件。

  • 封装:SMC(DO-214AB),表面贴装封装,尺寸紧凑(约2.4×2.1×1.0mm),适配高密度PCB布局;
  • 型号含义:1.5关联峰值脉冲功率等级,SMCJ为系列标识,30对应反向截止电压30V,CA表示双向极性,R1_00001为生产规格后缀;
  • 核心定位:针对12V/24V等低压系统,抑制静电、电源开关浪涌、雷击等瞬态干扰。

二、核心电气参数详解

参数直接决定防护能力,需重点关注以下维度:

1. 电压特性参数

  • 反向截止电压(Vrwm):30V,即正常工作时器件允许施加的最大反向电压,未超过时保持高阻态,不影响电路;
  • 击穿电压(Vbr):38.3V(典型值),浪涌电压超过此值时器件反向击穿,触发保护;
  • 钳位电压(Vc):48.4V(典型值),浪涌电流通过时,器件两端电压被钳位至该值,确保后端电路电压不超限。

2. 电流与功率参数

  • 峰值脉冲电流(Ipp):31A(10/1000μs脉冲波形),10/1000μs为行业标准浪涌波形(前沿10μs达峰值,半峰值持续1000μs),可承受强浪涌冲击;
  • 峰值脉冲功率(Ppp):1.5kW(1ms脉冲时长),覆盖多数电源开关瞬态(如电机启停、继电器切换)的功率需求;
  • 反向漏电流(Ir):1μA(典型值),正常工作时漏电流极低,不增加后端电路功耗,适配电池供电设备。

三、主要应用场景

该器件适配低电压系统的过压防护,典型应用包括:

  1. 消费电子:手机、平板、笔记本的USB接口、HDMI接口、音频接口的ESD保护;便携设备电池充电电路的浪涌抑制;
  2. 通信设备:路由器、交换机、光模块的以太网端口、电源输入口的浪涌防护;基站设备低电压信号线路保护;
  3. 工业控制:PLC输入输出模块、传感器信号线路、12V/24V电源模块的过压保护;
  4. 汽车电子(若符合车规):12V辅助电源系统、车身控制模块(BCM)信号接口、车载充电器的浪涌防护。

四、性能优势与设计亮点

  1. 双向保护简化电路:无需区分正负极性,可同时抑制正/负浪涌,减少元件数量与布线复杂度;
  2. 低漏电流适配低功耗:1μA漏电流对电池供电设备友好,不额外增加功耗;
  3. 高脉冲耐受能力:1.5kW峰值功率+31A峰值电流,可应对雷击、静电放电(8kV接触放电)等极端干扰;
  4. 紧凑封装易集成:SMC封装支持回流焊,适配小型化、高密度PCB设计(如智能手表、蓝牙耳机);
  5. 强茂品质可靠:PANJIT成熟工艺确保器件多次浪涌冲击(≥1000次循环)后性能稳定,工作温度范围-55℃~+150℃(工业级)。

五、选型参考与替代建议

若需调整参数,可参考同系列型号:

  • 更高电压:1.5SMCJ33CA(Vrwm=33V)、1.5SMCJ36CA(Vrwm=36V);
  • 更高功率:2.0SMCJ30CA(Ppp=2kW);
  • 单向保护:1.5SMCJ30A(单向极性,仅抑制正浪涌)。

该器件以高性价比、紧凑封装和可靠防护能力,成为低压系统过压保护的主流选择,广泛应用于消费、通信、工业等领域。

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
