SMAJ150A/TR13是台湾君耀(Brightking)推出的单向瞬态抑制二极管(TVS),专为150V等级电路的瞬态过压防护设计,核心作用是在电路遭遇雷击、静电放电(ESD)、开关浪涌等瞬态高压冲击时,快速导通并钳位电压至安全范围,避免后级敏感元器件(如IC、MOS管、传感器等)被击穿损坏。
作为TVS器件,其响应速度达ns级(典型<1ns),能在瞬态过压发生的瞬间完成防护动作,远快于普通稳压管,是工业控制、通信、车载等领域过压防护的主流选型之一。
该型号的核心参数直接决定了其防护能力与适用场景,具体解析如下:
SMAJ150A/TR13采用SMA封装(DO-214AC),小型贴片设计,尺寸约2.9mm×5.1mm×1.6mm,具有以下优势:
结合参数特性,该型号主要适用于:
该型号凭借宽温、低漏、小封装等特性,成为150V等级电路过压防护的高性价比选型,广泛应用于工业、通信、车载等领域。

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.
