PANJIT P6SMB33A_R1_00001 TVS二极管产品概述

一、产品定位与核心功能

P6SMB33A_R1_00001是PANJIT(强茂)推出的双向瞬态抑制二极管(TVS),核心作用是为电子电路提供静电放电(ESD)和浪涌脉冲的双向防护,防止后级敏感元器件(如MCU、传感器、通信接口芯片等)因过压冲击损坏。该器件采用表面贴装封装,体积紧凑,适配高密度PCB设计,是工业控制、消费电子、汽车电子等领域的通用防护器件。

二、关键电气参数深度解析

1. 极性与静态工作特性

  • 双向极性:无需区分正负极,简化电路布局,适配双向信号接口(如USB、以太网);
  • 反向截止电压(Vrwm)28.2V:正常工作时反向偏置不导通,可承受最大直流/交流峰值电压,确保电路静态稳定;
  • 反向漏电流(Ir)1μA:静态功耗极低,不影响电路正常功能。

2. 浪涌防护核心参数

  • 击穿电压34.7V:浪涌超过阈值时快速导通,响应时间<1ns(TVS典型响应特性);
  • 钳位电压45.7V:导通后将过压钳位至安全值,远低于多数敏感IC的最大耐压(如5V系统后级器件耐压多<50V);
  • 脉冲耐受能力:支持10/1000μs标准浪涌波形(模拟工业/电源浪涌),峰值脉冲电流(Ipp)13.2A、峰值脉冲功率(Ppp)600W,可应对电源尖峰、雷击感应浪涌及ESD冲击。

3. 环境适应性

  • 工作温度范围-55℃~+150℃:覆盖工业级(-40℃+85℃)、汽车级(-55℃+125℃)等恶劣环境需求。

三、封装与可靠性设计

该器件采用SMB封装(DO-214AA),尺寸约2.7mm×5.2mm×1.0mm,体积紧凑,适配高密度PCB(如手机主板、工业控制板接口区);封装材料耐高温,兼容回流焊工艺,生产兼容性强。

此外,器件符合IEC 61000-4-2静电防护标准,可有效抑制人体接触、设备插拔等场景的ESD冲击,满足电子设备EMC(电磁兼容性)要求。

四、品牌与典型应用场景

PANJIT(强茂)是台湾老牌半导体厂商,专注功率器件、TVS/ESD防护领域,产品以高可靠性、高性价比著称,广泛应用于全球电子行业。

P6SMB33A_R1_00001的典型应用包括:

  • 工业控制:PLC I/O接口、传感器模块、电机驱动电路;
  • 消费电子:手机/平板USB接口、耳机接口、充电端口;
  • 汽车电子:车载传感器(胎压监测、摄像头)、ECU输入输出端口;
  • 通信设备:路由器/交换机以太网接口、无线模块射频端口。

五、选型与使用注意事项

  1. 选型匹配:钳位电压需≤0.8×后级器件最大允许电压(如后级耐压50V,45.7V符合要求);
  2. 极性确认:双向设计无需区分正负极,避免与单向TVS混淆(单向适用于单方向信号);
  3. 焊接建议:SMB封装采用回流焊工艺,焊接温度需符合datasheet要求(避免>260℃/10s),防止封装损坏。

该器件凭借双向防护、宽温适应性及高脉冲耐受能力,成为多领域过压防护的实用选择。

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
