Brightking 1.0SMB33CA-AT/TR13 瞬态抑制二极管（TVS）产品概述
一、产品定位与核心功能
1.0SMB33CA-AT/TR13是台湾君耀（Brightking）推出的双向瞬态抑制二极管（TVS），核心作用是为电子电路提供瞬态过压防护——快速抑制静电放电（ESD）、雷电浪涌、电源开关瞬态等异常高压脉冲，避免后级敏感元器件（如MCU、传感器、通信芯片）被击穿损坏，是电子设备抗干扰设计中常用的核心防护器件。
二、核心电气参数解析
该器件参数精准匹配中低电压电路的防护需求，关键指标如下：
- 极性：双向设计，无需区分电路正负极，可同时防护双向过压脉冲，简化电路布局；
- 反向截止电压（Vrwm）：28.2V，正常工作时（电压低于此值）呈高阻态，漏电流仅1μA，不影响电路信号传输；
- 击穿电压（Vbr）：34.7V，过压触发阈值，当电路电压超过此值时，器件ns级快速导通；
- 钳位电压（Vc）：45.7V，导通后将电路电压钳位在该值以内，确保后级器件工作电压不超耐受极限；
- 峰值脉冲电流（Ipp）：22.2A，单次最大浪涌电流承受能力，覆盖常见瞬态干扰强度；
- 峰值脉冲功率（Ppp）：1kW（10/1000μs波形），浪涌功率容量满足工业/消费电子典型需求；
- 工作温度：-55℃~+150℃，宽温设计适配极端环境（如户外设备、车载系统）。
三、封装与可靠性设计
- 封装类型：采用SMB表面贴装封装（1.0SMB标识对应），尺寸紧凑（约2.9×3.8×1.9mm），适合高密度PCB布局，支持自动化贴装，提升生产效率；
- 防护标准：符合IEC 61000-4-2静电放电标准（可承受4kV接触放电、8kV空气放电），同时宽温特性、低漏电流确保长期使用无老化失效；
- 包装形式：TR13为编带包装（tape and reel），每盘数量符合SMT生产线批量使用需求。
四、典型应用场景
- 工业控制：PLC模块、传感器接口、电机驱动电路，防护现场浪涌干扰（如电机启停、雷电感应）；
- 汽车电子：车载显示屏、CAN总线接口、传感器（温度/压力），适配车载宽温环境；
- 消费电子：手机/平板USB接口、耳机孔、充电端口，防护用户插拔时的静电；
- 通信设备：路由器、交换机以太网端口、射频接口，抑制线路浪涌；
- 低电压电源：12V/24V直流电源输出端，防护开关瞬态过压。
五、品牌与品质保障
Brightking（君耀）是台湾老牌防护器件厂商，专注TVS研发超20年，产品符合RoHS、REACH环保标准，1.0SMB33CA系列经过温度循环、湿度老化等严格测试，批量一致性与长期稳定性可靠，是电子设备防护的高性价比选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
