产品概述

SMCJ85CA 产品概述

一、产品简介

SMCJ85CA 为 MDD 品牌的瞬态电压抑制（TVS）二极管，采用 SMC/DO-214AB 表面贴装封装，针对电路板空间有限的应用设计。器件具有低轮廓、低电感和玻璃钝化结结构，提供可靠的浪涌保护与长期稳定性。

二、主要电气参数

反向额定电压 (Vrwm)：85 V
击穿电压 (VBR)：典型 104 V
钳位电压：137 V（在额定峰值脉冲电流条件下）
峰值脉冲电流 (Ipp)：11 A
峰值脉冲功率 (Ppp)：1500 W（1.5 kW）
反向漏电流 (Ir)：1 μA（常温下）
工作温度范围：-65 ℃ ~ +150 ℃

三、结构与特性

该器件采用玻璃钝化结工艺，具有出色的热稳定性和低漏电特性。内置应力消除结构与低电感封装，使其在脉冲冲击时响应迅速、钳位性能优异。SMC/DO-214AB 封装兼顾机械强度与散热能力，适合高能量脉冲吸收场景。

四、典型应用场景

I/O 接口保护（通信端口、接口卡）
AC / DC 电源浪涌抑制（电源输入端、开关电源）
工业控制设备与汽车电子辅助保护（遵循工作温度要求）
需要表面贴装、低电感保护器件的其他电子系统

五、使用与布局建议

为达到最佳保护效果，建议将 SMCJ85CA 尽量靠近被保护端口焊接，缩短导线长度并保证良好散热。对高能脉冲场合应考虑 PCB 的散热铜箔与稳固焊盘设计，以利器件吸收能量并维持温升在安全范围内。

六、优势小结

SMCJ85CA 提供 85 V 等级的稳健反向保护、137 V 的有效钳位以及 1.5 kW 的瞬态吸收能力，结合低漏电与宽温度范围，适合对空间、响应速度与可靠性有较高要求的浪涌防护设计。若需批量采购或索取封装尺寸与规范书，可联系 MDD 或其授权代理。
