SMCJ20CA/TR13 产品概述
一、产品简介
SMCJ20CA/TR13 是台湾君耀（Brightking）生产的一款双向瞬态电压抑制（TVS）二极管，采用 SMC（DO-214AB）表面贴装封装。该器件用于抑制电源或信号线上发生的瞬态过压，如雷击、开关瞬变和静电放电，保护下游元件免受损坏。
二、主要规格（典型值）
- 极性：双向
- 反向截止电压 Vrwm（工作电压）：20 V
- 击穿电压 Vbr（典型）：22.2 V
- 钳位电压 Vc（在峰值脉冲条件下）：32.4 V
- 峰值脉冲电流 Ipp：46.3 A
- 峰值脉冲功率 Ppp（瞬态能量能力）：1.5 kW（按制造商测试波形）
- 反向漏电流 Ir（在 Vrwm 下）：1 μA
- 工作温度范围：-65 ℃ 至 +150 ℃
- 封装：SMC (DO-214AB)
这些参数表明器件在 20 V 等级的电源或信号线上能提供较强的瞬态抑制能力同时保持很低的漏电。
三、典型应用
- 工业电源与配电保护（DC 总线、继电器线圈抑制）
- 通信设备与基站前端防护
- 电池管理与充电接口过压保护
- 数据线、接口（USB、串口等）瞬态抑制（需结合电路等级选择）
- 适用于宽温环境下的防护场景（航天、户外仪表、严苛工业环境）
四、使用建议与注意事项
- 将 TVS 器件尽量靠近需要保护的器件或输入端放置，以缩短回路并降低感性延迟。
- 为保证钳位性能，尽量减少 PCB 上的串联阻抗和引线长度。
- 在长时间反复冲击或高能量条件下应注意热耗散与结温上升，必要时采用散热辅助或串联限流措施。
- 该器件为双向结构，适合交流或双向浪涌环境；若为单向直流系统，请确认选型。
- 对于汽车级应用，请向厂商确认是否通过 AEC-Q100 等认证。
五、采购与验证建议
订购时请注意完整料号（SMCJ20CA/TR13 通常表示带卷装/带盘包装），并向供应商索取详尽数据手册以核实测试波形（如 8/20 µs 或 10/1000 µs）、钳位测试电流条件和热阻等详细参数。设计前建议在目标系统上进行 IEC/EN 浪涌与 ESD 测试验证，确保实际防护效果满足系统要求。

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