SJD12A28L01 为 Brightking(台湾君耀)推出的一款单向ESD保护二极管,封装为SOD-123S,型号面向需要高可靠瞬态抑制的小型化应用。器件设计用于在瞬态过压时快速钳位并将冲击能量导入地线,从而保护下游敏感器件和接口电路。
该器件在8/20μs浪涌条件下能承受高达1kW的瞬时功率并提供约4.4A的峰值浪涌电流;工作时保持较低的反向漏电(1 μA),在正常工作电压下对信号影响小。击穿和钳位特性保证在ESD事件发生时迅速进入导通并将过压限制在设备可承受范围内。
适用于USB、串行数据接口、网络通信端口、SIM卡/SD卡接口、移动与消费电子、工控信号线、显示接口等对ESD防护有严格要求的场合。特别适合空间受限且需表面贴装的电路板设计。
SOD-123S 小型封装便于高密度贴装。推荐将器件尽量靠近被保护的输入/输出接口引脚放置,走线最短以减小寄生感抗。建议在GND侧使用完整地平面或多点焊盘,并在高能量应用中考虑适量散热铜面积或热沉布局以提升能量耗散能力。
SJD12A28L01以其低漏电、快速响应和小型封装,适合对体积与可靠性有较高要求的接口保护设计。

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.
