P6SMBJ28A_R1_00001 产品概述

一、产品简介

P6SMBJ28A_R1_00001 是强茂(PANJIT)推出的一款表面贴装型瞬态电压抑制器(TVS),封装为 DO-214AA(SMB)。该器件专为静电放电(ESD)与雷击/浪涌保护设计,具有快速响应、低漏电、高能量吸收能力的特点,适用于各种需要过压保护的电源与信号线。

二、主要参数(关键标称)

  • 类型:TVS(单向,适用于直流线路防护)
  • 反向工作电压 Vrwm:28 V
  • 击穿电压 VBR:34.4 V
  • 钳位电压 Vc(Ipp 对应):45.4 V
  • 峰值脉冲电流 Ipp:13.2 A(10/1000 μs 波形)
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs 波形)
  • 反向漏电流 Ir:1 µA(典型/最大)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装/外形:SMB(DO-214AA)

三、功能特性与优势

  • 快速钳位:在浪涌发生时迅速进入雪崩区,将过电压钳制在安全电平(钳位电压 45.4 V),保护后端电路免受瞬态冲击。
  • 高频能量吸收:额定 600 W(10/1000 μs)峰值功率和 13.2 A 峰值脉冲电流,能承受典型雷击或电网干扰引起的能量注入。
  • 低漏电流:1 µA 的反向电流便于用于低功耗或待机电路,降低静态损耗。
  • 宽温度范围:-55 ℃ 至 +150 ℃,适合工业级与汽车电子等苛刻环境。

四、典型应用场景

  • 电源输入防护:DC 电源线路(例如 24 V 或 28 V 系统)的前端过压保护。
  • 通信与接口保护:以太网、串口、USB/串行信号端口的浪涌与 ESD 防护(根据线路类型选择单/双向)。
  • 工业控制与电源模块:变频器、PLC、电源适配器输入端保护。
  • 汽车电子(需评估是否满足车规标准):CAN、车载电源辅助防护。

五、使用建议与设计注意事项

  • 选择原则:Vrwm 应略高于被保护线路的正常工作电压,保证不在正常工作条件下导通;钳位电压应低于被保护器件的最大耐压。
  • 布局建议:将 TVS 尽量靠近被保护端口或电源入口焊盘放置,走线尽量短且宽,以减少串联电感与电阻,提升钳位效果。
  • 散热与寿命:虽为表面贴装器件,但在高能量冲击后会产生热量,建议预留合适铜箔散热区并遵循回流焊工艺规范;必要时采用并联或外部限流措施以提高冲击承受能力。
  • 极性与选型:本型号为单向 TVS(通常带阴极条标识),用于直流系统;若用于交流/双向信号,请选择相应的双向 TVS 器件。

六、包装与可靠性

SMB(DO-214AA)封装具备良好的机械强度与焊接可靠性,适合自动贴装与回流焊工艺。器件耐温范围和低漏电特性使其适配多种工业环境,但在实际使用中仍建议参考厂商数据手册的详细电气特性曲线与热特性进行设计验证。

总结:P6SMBJ28A_R1_00001 是一款性能均衡的 SMB 封装单向 TVS 器件,适合为 28 V 级别或附近的直流电源及信号线提供高能量浪涌与 ESD 保护。在设计时合理选择 Vrwm、优化 PCB 布局并注意散热与工艺,可以显著提升系统的抗扰性与可靠性。若需更详细的曲线、封装尺寸或可靠性测试数据,请参考厂商数据手册或联系供应商获取。

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
