SMBJ15CA（MDD）TVS 二极管产品概述
一、产品概述
SMBJ15CA 是 MDD 出品的双向瞬态电压抑制（TVS）二极管，封装为 SMB (DO-214AA)。器件设计用于吸收和钳位由浪涌、电快速瞬变（EFT）及雷击诱发的高能脉冲，保护直流和交流电源线、信号线及敏感电子元件。器件工作可靠，适合工业级和汽车级环境下长期运行。
二、主要电气参数
- 反向工作电压 Vrwm：15 V（标称）
- 击穿电压 Vbr：18.5 V（典型）
- 钳位电压 Vc：24.4 V（在 Ipp 条件下）
- 峰值脉冲功率 Ppp：600 W（10/1000 μs 波形）
- 峰值脉冲电流 Ipp：24.6 A（10/1000 μs 波形）
- 反向泄漏电流 Ir：1 μA（在 Vrwm 条件下）
- 极性：双向
- 工作温度范围：-65 ℃ ～ +150 ℃
三、关键特性
- 双向结构可直接用于交流和双极性脉冲保护，无需额外极性处理。
- 低静态漏电（1 μA），在待机和低功耗系统中干扰小。
- 在标准 10/1000 μs 浪涌波形下能量吸收能力强（600 W），适合电源和通信接口的浪涌保护。
- 宽温度工作范围，适应严苛环境和高可靠性要求的应用场合。
四、典型应用
- 开关电源输入端、直流总线与滤波电容保护。
- 工业控制器、PLC、电机驱动器的浪涌与反向过压保护。
- 通信设备、基站、POE 供电系统及以太网接口防护。
- 汽车电子（车载电源线、传感器接口）与户外设备防雷击保护（视系统要求配合合适的级联保护）。
五、封装与可靠性
封装为 SMB (DO-214AA)，便于表面贴装或混合贴装工艺。器件热阻和机械强度适合波峰或回流焊工艺，推荐遵循厂商的焊接温度曲线以保证长期可靠性。高温工作上限 +150 ℃，适合高温应用或受热集中的电路板区域。
六、选型与使用建议
- 若系统工作电压接近 15 V，应确认在 Vrwm 下泄漏满足要求并考虑钳位余量。
- 在强雷击或更大浪涌环境下，可与更高能量级的防护器件（如气体放电管或更大功率 TVS）并联/级联使用。
- 布局上尽量缩短保护器件到被保护器件之间的走线，减小寄生电感以提高钳位效果。
总结：SMBJ15CA（MDD）是一款适用于工业与通信场景的双向 SMB TVS，具备 15 V 反向工作电压、24.4 V 钳位（在规定波形下）和 600 W 峰值脉冲能量，适合对浪涌和瞬态过压有较高可靠性要求的系统。

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.
