SMBJ75CA是伯恩半导体(BORN)推出的一款双向瞬态抑制二极管(TVS),专为低压电路的过压防护设计,采用SMB(DO-214AA)表面贴装封装,具备宽工作温度范围、低漏电流等特点,可有效抑制静电放电(ESD)、浪涌脉冲等瞬态干扰,保障电路稳定运行。
SMBJ75CA属于双向TVS器件,无需区分正负极性,可同时防护电路正负方向的过压冲击;核心定位为低压直流/交流电路的瞬态过压保护元件,适用于对体积、可靠性要求较高的电子设备。
该器件的关键电性能参数针对常见浪涌场景优化,具体如下:
SMBJ75CA采用SMB(DO-214AA)表面贴装封装,尺寸紧凑(典型值:2.9mm×5.0mm×2.4mm),适配自动化贴装产线,同时满足高密度电路板的布局需求。
可靠性方面,器件通过严格的环境测试(如温度循环、湿度老化),多次浪涌冲击后性能无明显衰减,可长期稳定工作于恶劣工况。
基于其双向防护、宽温特性,SMBJ75CA广泛应用于以下场景:
相比同类TVS器件,SMBJ75CA具备以下核心优势:
该器件是低压电路过压防护的高性价比选择,可有效提升电子设备的抗干扰能力与可靠性。

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.
