SMBJ110CA/TR13是台湾君耀(Brightking)推出的双向贴片瞬态抑制二极管(TVS),采用SMB(DO-214AA)封装,专为电子设备的瞬态过压防护设计,可有效抑制静电放电(ESD)、雷电感应浪涌及电路开关瞬态干扰,保障敏感元器件(如MCU、传感器、通信芯片)的正常工作。产品兼顾小体积、高防护能力与宽温适应性,是工业、通信、消费电子等领域的高性价比防护方案。
SMBJ110CA/TR13的核心定位是中低压电路的双向瞬态过压防护器件,无需区分正负极,适配交流/直流双向浪涌场景,典型应用包括:
产品参数围绕“瞬态防护能力”与“正常工作稳定性”设计,核心参数及意义如下:
极性:双向设计
无需区分正负极,简化电路设计与焊接工艺,适配交流/直流双向浪涌(如电源正负极反接、通信线双向干扰)。
反向截止电压(Vrwm):110V
正常工作状态下(无浪涌),器件可承受的最大反向电压,此时处于截止状态,漏电流极小,不影响电路正常运行。
击穿电压(Vbr):122V(典型值)
器件开始导通的电压阈值——当浪涌电压超过122V时,TVS迅速从截止态转为低阻态,将电压钳位在安全范围。
钳位电压(Vc):177V(@Ipp=3.4A)
浪涌峰值电流下器件两端的最大电压,是保护后端电路的核心指标(需确保Vc低于被保护元器件的耐压极限)。
峰值脉冲电流(Ipp):3.4A
器件可承受的单次峰值浪涌电流(μs级),超过该值可能导致器件失效,需与电路浪涌能量匹配。
峰值脉冲功率(Ppp):600W
浪涌时的最大功率耗散,反映器件防护能力上限(Ppp = Vc × Ipp,体现单次浪涌的能量耐受)。
反向漏电流(Ir):1μA(@Vrwm)
正常工作时漏电流极小,对电路功耗影响可忽略,提升系统能效与长期稳定性。
工作温度范围:-65℃+150℃
宽温设计,满足工业级(-40℃+85℃)、车载级(-40℃~+125℃)等恶劣环境需求,支持极端温度下的持续工作。
SMB封装特点
采用DO-214AA贴片封装,体积仅约2.5×5.0×1.0mm,适合高密度PCB布局;支持回流焊工艺(260℃/10s),生产效率高,适配自动化组装线。

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
