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。

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.
