SMAJ15CA 是一款双向瞬态电压抑制二极管(TVS),由华轩阳电子(HXY MOSFET)提供,采用 SMA(DO-214AC)表面贴装封装。器件设计用于对瞬态过压(如雷击浪涌、电源突变、电磁干扰等)提供高效钳制保护,典型用于 15V 额定系统的浪涌抑制与瞬态抑制。该器件在保持低静态泄漏电流的同时,能够在短时间内承受高能量脉冲(峰值脉冲功率 400W),适合做一级或二级浪涌保护元件。
以上参数表明 SMAJ15CA 可在 15V 工作电压下稳定工作,并在瞬态事件中将电压钳制到约 24.4V 的水平,防止下游电路因过压而损坏。
SMAJ15CA(华轩阳电子)是一款适用于 15V 轨道的双向 TVS 器件,提供约 24.4V 的有效钳位、400W 的短时吸收能力及较低的泄漏电流。其 SMA 封装便于自动化贴装和高密度布板,适合工业、通信与消费类系统的瞬态浪涌保护。在实际应用中,应关注测试条件与实际浪涌类型的匹配、钳位电压对下游电路的影响以及散热和重复浪涌能力的设计细节,以确保长期可靠运行。若需用于更苛刻的环境(如车规级或高能量反复冲击),建议与供应商确认更多可靠性与测试数据或选择更高能量等级的 TVS 器件。

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.
