SMCJ15CA是RUILON(瑞隆源)品牌推出的双向瞬态抑制二极管(TVS),属于贴片式过压保护器件,核心作用是快速响应瞬态过压脉冲(如雷击、静电放电、电源浪涌),保护后端敏感电子元器件免受损坏。其型号中:
该器件关键参数围绕“过压防护能力”与“工作稳定性”设计,具体如下:
参数名称 数值/条件 作用说明 反向截止电压(Vrwm) 15V 正常工作时可承受的最大直流/峰值交流电压,避免器件误触发 击穿电压(Vbr) 18.5V 电压超过此值时,器件进入导通状态,启动过压抑制 钳位电压(Vc) 24.4V 峰值脉冲下的最大电压降,直接决定后端器件的保护阈值 峰值脉冲电流(Ipp) 61.5A@10/1000μs 工业标准浪涌波形(上升沿10μs、半峰值1000μs)下的最大耐受电流 峰值脉冲功率(Ppp) 1.5kW@10/1000μs 浪涌功率容量,反映器件的浪涌耐受能力 反向漏电流(Ir) 1μA(额定电压下) 正常工作时的泄漏电流,数值小则系统功耗损耗低SMCJ15CA采用SMC(DO-214AB)贴片封装,具备以下特点:
该器件针对低电压系统的过压防护需求,广泛应用于:
SMCJ15CA凭借双向防护、小体积、宽温可靠等特性,成为低电压系统过压保护的主流选型之一,适用于从消费电子到工业控制的多场景需求。

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.
