SMDJ22CA 产品概述
一、产品简介
SMDJ22CA 是伯恩半导体（BORN）推出的一款高能脉冲吸收二极管，属于TVS（瞬态电压抑制器）系列，单路双向保护，封装为 DO-214AB。该型号专为电源口与直流供电线的浪涌保护设计，能在瞬态过压时迅速钳位电压，保护后端敏感器件免受损坏。
二、主要参数
- 极性：双向
- 反向截止电压（VRWM）：22 V
- 击穿电压（VBR）：24.4 V
- 钳位电压：84.5 V
- 峰值脉冲电流（Ipp）：84.5 A（按制造商脉冲测试条件）
- 反向电流（Ir）：2 µA
- 峰值功率能力：3000 W（脉冲能量等级）
- 通道数：单路
- 工作温度范围：-55 ℃ 至 +150 ℃
- 封装：DO-214AB（SMD）
三、主要特性
- 双向结构，可同时对正负极性瞬态进行抑制，适用于交流或需双向保护的直流线路。
- 低泄漏电流（Ir≈2µA），在正常工作电压下对电路几乎无影响。
- 高峰值钳位能力和大电流吸收能力（Ipp≈84.5A），能承受强脉冲浪涌并将电压限制在安全范围。
- 宽工作温度范围，适合工业与汽车电子等恶劣环境。
四、典型应用
- 电源插口与DC输入保护
- 通信与基站设备的电源保护
- 工业控制、PLC、电源模块浪涌防护
- 汽车电子系统（在满足系统认证要求下）
- 其他要求高能量浪涌吸收的接口和线路保护场合
五、使用建议与注意事项
- 为获得标称吸收能力，请参考制造商的脉冲测试条件进行系统级设计（选择合适的浪涌波形与能量等级）。
- PCB 布局应将 TVS 近源放置，尽量缩短到保护目标的走线长度并加粗铜厚以降低串联阻抗。
- 焊接时遵循封装的热循环及回流温度规范，以免影响器件可靠性。
- 在高能量冲击场景下，可并联或与限流元件（如熔断器、PTC）配合使用以延长系统寿命并保护 TVS 本体。
六、封装与可靠性
DO-214AB 表面贴装封装便于高速自动贴装与回流焊工艺，封装机械强度高、热阻性能稳定。器件在-55 ℃ 到 +150 ℃ 温度范围内可靠工作，适用于长寿命和高可靠性要求的系统。选型时建议结合系统浪涌谱、环境温度与热散设计进行综合评估。
如需具体的脉冲测试波形、能量曲线或封装及焊接工艺说明书（数据手册），建议向伯恩半导体获取 SMDJ22CA 的完整技术资料以便做进一步的设计验证。
Request for quote
Send RFQ
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.
