TPSMC36CA 产品概述
一、概述
TPSMC36CA 是 Littelfuse（美国力特）出品的一款汽车级双向瞬态电压抑制（二极管 TVS），满足 AEC-Q101 可靠性要求，封装为 DO-214AB（SMCJ）两引脚结构。该器件针对车载电源和信号线上发生的雷击、负载开关、电磁脉冲等瞬态过压，提供高速夹断保护，显著降低系统损坏风险。
二、主要电气参数
- 反向截止电压 Vrwm：30.8 V（工作耐压，应高于系统正常工作电压）
- 击穿电压 Vbr：34.2 V（器件进入钳位状态前的起始电压）
- 钳位电压 Vc（在峰值脉冲条件下）：49.9 V
- 峰值脉冲电流 Ipp：30.5 A（对应钳位电压时的脉冲电流）
- 峰值脉冲功率 Ppp：1.5 kW（在标准脉冲条件下的能量吸收能力）
- 类型：双向 TVS（二极管型，可用于双向/交流抑制）
三、关键特性
- 汽车级质量，AEC-Q101 认证，适合车载环境的温度和振动考核。
- 双向工作，无极性限制，适用于交流或双向瞬态保护场合。
- 高峰值功率吸收能力（1.5 kW），在高能量脉冲下仍能保持低钳位电压。
- SMC 封装（DO-214AB）便于波峰或回流焊装配，散热性能良好，便于 PCB 布局处理大电流路径。
四、应用场景
- 车载总线与电源线瞬态保护（例如 12V/24V 系统的感性负载开关、负载突变抑制）
- 车载通信/信号线防雷击与静电打击（ADC、CAN 总线、LIN 等需选择合适 Vrwm）
- 工业控制、电源模块、逆变器等存在高幅值脉冲干扰的场合
五、选型与使用建议
- 确认系统最大工作电压低于 Vrwm（30.8 V），且有足够安全裕度。
- 若系统可能出现更高幅值或长时间冲击，应考虑并联或升级更高功率级别器件。
- PCB 布局尽量缩短器件到受保护节点的走线，增大焊盘和铜箔面积以利散热并降低串联电感。
- TVS 为瞬态抑制元件，非连续导通器件；若存在连续过压或持续高电流场景，应配置相应的限流或断路保护。
六、可靠性与封装
SMCJ（DO-214AB）封装兼顾机械强度和热性能，适合自动化贴装与回流焊流程。作为 Littelfuse 的汽车级产品，TPSMC36CA 在温度循环、机械振动和冲击等可靠性项目上通过 AEC-Q101 规范要求，适用于苛刻环境。

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.
