SMAJ5.0CA-TP是MCC(美微科)推出的双向瞬态抑制二极管(TVS),核心作用是快速响应电子设备中的瞬态过压(如静电放电、浪涌脉冲),将电压钳位在安全范围,避免后端敏感元器件(如IC、传感器、LED)损坏。
该产品适配高密度PCB设计,典型应用场景包括:
TVS的防护性能由核心参数决定,以下是SMAJ5.0CA-TP的关键参数及实际意义:
SMAJ5.0CA-TP采用SMA封装(DO-214AC),具备以下优势:
该产品符合IEC 61000-4-2标准(国际电工委员会静电放电测试规范),防护能力达到:
此外,产品可应对电快速瞬变脉冲群(EFT)、雷击浪涌(部分场景),但需结合实际电路设计。
TVS采用并联防护方式,以下是两种常见场景:
注意:并联时需确保TVS的Vrwm略高于电路正常电压,钳位电压低于后端器件最大耐压。
选型匹配:
焊接注意:
安装位置:
SMAJ5.0CA-TP凭借双向防护、小体积、快响应等优势,成为5V电路过压防护的高性价比选择,广泛适配消费电子、通信等领域的小型化设计需求。

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.
