SMBJ24CA是一款双向瞬态抑制二极管(TVS),采用DO-214AA(SMB)表面贴装封装,由国内保护器件厂商DOWO(东沃)生产。作为电路浪涌防护的核心器件,它能在遭遇瞬态过压(如静电放电、电源浪涌、雷击感应等)时,快速导通并钳位电压,将后端敏感元器件(IC、MOS管、传感器等)的工作电压限制在安全阈值内,避免过压损坏导致设备故障。
SMBJ24CA的参数针对中低压电路优化,核心参数及实际意义如下:
SMBJ24CA采用DO-214AA(SMB)封装,尺寸紧凑(约2.5mm×4.5mm×1.5mm),适合高密度PCB布局;支持自动贴装(SMT)工艺,焊接兼容性强(常规回流焊峰值温度260℃以下无损伤)。引脚采用铜基镀锡工艺,抗氧化性好,长期使用不易虚焊。
凭借小体积、中功率保护能力,SMBJ24CA广泛应用于:
DOWO(东沃)SMBJ24CA符合RoHS、REACH环保标准,经浪涌循环测试(多次10/1000μs 600W冲击)后性能稳定,温度范围-55℃~+150℃,满足工业级与消费级设备的可靠性需求。
综上,SMBJ24CA是一款性价比高、适配性强的双向TVS,适合小体积、中功率浪涌防护场景。

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.
