1.5SMC36CA_R1_00001是台湾强茂(PANJIT)推出的双向瞬态抑制二极管(TVS),专为静电放电(ESD)和瞬态浪涌过压防护设计,采用DO-214AB(SMC)表面贴装封装,兼具高脉冲耐受能力与宽温适应性,广泛适配工业、汽车、通信等领域的过压防护需求。
该器件属于TVS保护系列,核心作用是快速响应瞬态过压:当电路中出现静电放电(如人体接触、设备插拔)或浪涌脉冲(如电源开关、雷击感应)时,能在纳秒级时间内从高阻态转为低阻态,将过电压钳位在安全范围内,避免后级敏感电子元件(如MCU、传感器、通信芯片)被击穿损坏。双向极性设计使其无需区分正负,可直接并联于电源或信号端口,简化电路设计。
极性与截止电压
采用双向极性,常态下反向截止电压(Vrwm)为30.8V,即电路正常工作时(电压≤30.8V),器件处于高阻状态,漏电流极低(反向电流Ir=1μA),不影响原电路正常运行。
击穿与钳位特性
当电压超过击穿电压(Vbr=37.8V)时,器件快速导通;导通后将过电压钳位至49.9V(钳位电压Vc),确保后级电路电压不超过安全阈值,这是TVS保护的核心性能指标。
脉冲耐受能力
峰值脉冲电流(Ipp)达30A(测试条件:10/1000μs脉冲波形,即上升沿10μs、下降沿1000μs的标准浪涌波形),峰值脉冲功率(Ppp)为1.5kW(测试条件:1ms脉冲),可有效承受中等功率的浪涌冲击,适配多数工业/汽车级应用的浪涌防护需求。
宽温工作范围
工作温度覆盖-55℃至+150℃,满足汽车电子(如车载ECU、传感器)、工业控制(如PLC、现场总线)等恶劣环境下的长期稳定运行,符合车规级与工业级温度要求。
该器件采用DO-214AB(SMC)表面贴装封装,具有以下优势:
基于其双向防护、宽温适配与中等脉冲耐受能力,1.5SMC36CA_R1_00001广泛应用于:
PANJIT(强茂)作为全球知名半导体厂商,专注于功率器件、保护器件研发生产超过30年,产品符合RoHS、REACH等环保标准,且该型号经过严格的脉冲测试、温度循环测试、振动测试等,确保在极端环境下的性能稳定性。此外,DO-214AB封装为行业通用标准,便于客户在设计中替换或升级。
综上,1.5SMC36CA_R1_00001以双向防护、宽温适配、高脉冲耐受能力为核心优势,是工业、汽车、通信等领域过压防护的可靠选择,兼具性价比与可靠性。

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.
