P6SMB47CA是美国力特(Littelfuse)推出的一款双向瞬态抑制二极管(TVS),专为电子电路的瞬态过压防护设计,具备高功率容量、宽温适应和国际标准兼容等特点,广泛应用于消费电子、工业控制、汽车电子等领域。
作为TVS二极管家族中的一员,P6SMB47CA的核心作用是快速抑制电路中的瞬态浪涌电压(如静电放电ESD、电快速瞬变脉冲群EFT、雷击感应浪涌等),将电压钳位在安全范围内,避免后端敏感元器件(如MCU、传感器、接口芯片)被击穿损坏。其双向导通特性无需区分正负极,简化了电路设计与生产安装流程,适配各类通用电路的防护需求。
P6SMB47CA的电气参数经过严格校准,精准匹配中等电压等级电路的防护要求:
P6SMB47CA采用DO-214AA封装(即SMB封装),具备以下特点:
P6SMB47CA通过了IEC 61000-4-4(电快速瞬变脉冲群) 和 IEC 61000-4-2(静电放电) 国际防护标准认证,可有效应对常见的电磁干扰问题。其典型应用场景包括:
作为全球领先的过压保护器件厂商,Littelfuse(力特)对P6SMB47CA的可靠性进行了严格验证:
总结:P6SMB47CA以双向防护、宽温适应、高功率容量和国际标准兼容为核心优势,是中等电压电路瞬态过压防护的高性价比选择,适用于从消费电子到工业控制的多场景需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
