SMDJ28CA 是 BORN(伯恩半导体)推出的一款双向瞬态电压抑制(TVS)二极管,采用 SMC(DO-214AB)封装,面向需抗冲击、雷击和电涌保护的电源与信号线保护场景。该器件在大电流脉冲下能迅速钳位电压,保护后端敏感电子元件不受瞬态过电压损害,适用于工业、电信、电源和汽车等领域。
SMC(DO-214AB)封装提供较大的焊盘面积和散热路径,推荐在 PCB 设计中为器件提供短且宽的铜箔回流路径以增强散热。为提高可靠性,可在器件附近保留热隔离区域并避免紧靠高温器件布置。出厂和焊接时遵循制造商的回流曲线以防止热损伤。
SMDJ28CA 以其高能量吸收能力、低泄漏和宽温度特性,适合多种需要可靠浪涌保护的工业与通信场合。在选型与设计时,请结合实际浪涌水平与系统热设计进行验证以确保长期稳定运行。

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.
