P4SMAJ20A_R2_00001 产品概述

一、产品简介

P4SMAJ20A_R2_00001 是由 PANJIT(强茂)推出的一款单向 TVS 晶体管,用于瞬态过压保护。该器件采用 SMA 封装,额定脉冲功率 400W(10/1000µs),静态反向工作电压(Vrwm)为 20V,专为 12V/24V 等直流系统的浪涌与静电防护设计,兼顾高能脉冲吸收能力与低漏电特性,适合工业、电源、通信及汽车电子等场景。

二、主要性能参数

  • 极性:单向(UNI),适用于直流电源线保护。
  • 反向截止电压 Vrwm:20V。
  • 击穿电压 VBR:22.2V(标称值,按典型测试条件)。
  • 钳位电压:32.4V(在规定脉冲电流下的钳位水平)。
  • 峰值脉冲电流 Ipp:12.3A(10/1000µs 波形)。
  • 峰值脉冲功率 Ppp:400W(10/1000µs)。
  • 反向电流 Ir:1µA(在 Vrwm 条件下的漏电典型值)。
  • 工作温度范围:-55℃ 至 +150℃。
  • 防护等级:符合 IEC 61000-4-2(ESD)电磁兼容要求。
  • 封装:SMA,适合表面贴装生产工艺。

三、典型应用场景

  • 汽车电子 12V/24V 供电线的浪涌保护与电磁兼容抑制。
  • 工业控制设备与电源模块的入线防护,抵御雷击及开关瞬态。
  • 通信设备、路由器、电信端口的过压和静电保护。
  • 消费类电子(电源适配器、电视机顶盒)中对输入侧或敏感节点的瞬态抑制。

四、器件优势与设计要点

  • 高吸收能量:400W 瞬态功率与 12.3A 峰值电流的组合,能有效钳位大能量浪涌,保护下游器件免受过压损伤。
  • 低漏电:典型反向电流仅 1µA,有利于低功耗设备在待机或休眠状态下保持能耗最低。
  • 宽温度范围:-55℃ 至 +150℃,适应严苛环境和高温工况。
  • SMA 封装:尺寸小,便于贴片自动化生产与高密度 PCB 布局。
    设计时建议将 TVS 置于靠近外部引脚或接口位置,尽量缩短引线与布线长度,以降低寄生电感,提升钳位效率。

五、可靠性与合规

该型号符合 IEC 61000-4-2 对静电放电的防护要求,另外 PANJIT(强茂)在生产过程中执行严格的可靠性测试,包括功率循环、热冲击与高加速寿命试验(HAST),以保证在工业和汽车级应用中的稳定性。

六、选型与注意事项

  • 若目标系统为交流高压或双向保护,请选择相应双向或更高 Vrwm 的型号;本器件为单向型,适用于单极性直流线路。
  • 钳位电压 32.4V 在瞬态时能保护大多数 24V 及 12V 系统,但需确认被保护电路对短时高压峰值的耐受能力。
  • 布局时应尽量靠近受保护端口,并增加必要的滤波与限流元件以分担能量。
  • 留意焊接热敏性,遵循制造商的回流焊温度曲线以保证封装可靠性。

P4SMAJ20A_R2_00001 以其高能量吸收能力、低漏电及宽温适应性,成为工业、通信与汽车电子中保护关键节点的理想选择。若需进一步的电气特性曲线、封装尺寸或可靠性数据手册,可联系供应商获取完整资料。

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
