Brightking(台湾君耀)SET23A03L02 是一款专为电子设备静电放电(ESD)防护设计的单向贴片二极管,采用SOT-23小尺寸封装,适配3.3V系统的接口与敏感电路防护,具备宽温适应性与标准合规性,是工业、消费电子等领域的实用防护器件。
SET23A03L02由台湾君耀电子研发生产,属于单向ESD防护二极管,核心功能是在静电脉冲冲击时快速导通,将过压能量泄放至地,保护后端敏感元器件(如MCU、传感器、接口芯片)免受损坏。其封装为SOT-23(表面贴装),尺寸紧凑(典型值:长2.9mm×宽1.6mm×高1.1mm),可直接集成于高密度电路板,适配自动化贴装工艺,无需额外散热设计。
该器件参数针对3.3V系统优化,关键指标如下:
SET23A03L02严格遵循IEC 61000-4-2(静电放电抗扰度测试标准),可应对常见静电场景:
此外,该器件为单向防护,仅对某一方向过压脉冲泄放,适合电源正极到地等定向防护需求。
结合参数与特性,SET23A03L02适用于以下场景:
由于结电容为200pF,该器件更适合低速信号与模拟信号防护:
总结:SET23A03L02是一款性价比高的单向ESD防护二极管,针对3.3V系统优化,宽温适配多场景,适合低速接口与敏感电路的静电防护需求。

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.
