CJ BAR64-02V PIN二极管产品概述
一、产品基本定位与核心属性
CJ BAR64-02V是江苏长电（CJ）推出的一款超小型表面贴装PIN二极管，采用SOD-523封装，属于射频/高速控制类器件。其核心定位是面向中低端射频通信、工业控制、汽车电子等场景，兼顾低功耗、宽温适应性、高可靠性与成本优势，适合高密度PCB布局的小型化电路设计。
二、关键电气参数详解
BAR64-02V的电气参数经过优化，可满足多数实用场景需求，核心参数如下：
参数项 数值/条件 实际意义 正向压降（Vf） 1.1V @ 50mA 正向导通时电压降低，可降低电路功耗，适合低功耗射频模块设计 直流反向耐压（Vr） 150V 反向承受能力强，避免高频信号下的击穿风险，适配中等功率射频场景 连续整流电流（If） 100mA 最大连续正向工作电流，实际应用建议降额至80mA以内（提升可靠性） 反向漏电流（Ir） 10μA @ 150V 反向漏电流极小，减少反向功耗，保证电路稳定性（尤其是静态待机场景） 工作结温范围 -55℃ ~ +150℃ 宽温覆盖汽车电子（-40℃+125℃）、工业控制（-55℃+125℃）等极端环境需求三、封装与物理特性
BAR64-02V采用SOD-523超小型表面贴装封装，属于行业通用的微型封装类型，核心特点：
- 尺寸紧凑：参考行业标准（长1.6mm×宽0.8mm×高0.6mm），比常规0805封装更小，可大幅节省PCB空间；
- 环保无铅：符合RoHS 2.0及REACH标准，兼容回流焊、波峰焊等自动化生产工艺；
- 机械可靠性：封装强度满足振动、冲击测试要求，适合车载、工业等振动环境。
四、典型应用场景
BAR64-02V的PIN二极管特性（低插入损耗、快速开关响应）使其适配多种高频/控制场景：
- 射频开关：微波通信系统（如2.4G/5G无线模块）中的信号路径切换，实现多通道选择；
- 自动增益控制（AGC）：射频接收机中，通过调整二极管导通状态稳定信号增益，避免过载；
- 高速开关电路：测试仪器（如信号发生器、示波器）的信号切换，响应速度满足高频需求；
- 汽车电子：车载雷达、车机通信模块的射频控制元件，宽温范围适配汽车环境；
- 工业控制：传感器信号切换、PLC通信接口的控制，高可靠性满足工业级要求。
五、品牌与可靠性说明
CJ（江苏长电科技）是国内半导体行业龙头企业，具备完善的生产与质量管控体系：
- 认证资质：通过ISO9001、IATF16949（汽车级）等认证，产品一致性符合行业标准；
- 可靠性测试：BAR64-02V经过高低温循环（-55℃~+150℃）、湿度老化、机械振动等测试，量产故障率低；
- 成本优势：作为国产器件，性价比高于进口同类产品，适合批量应用。
六、选型与使用注意事项
为保证器件稳定性，实际应用需注意以下要点：
- 电流降额：连续正向电流不超过80mA，峰值电流参考 datasheet（一般≤1A@1ms）；
- 电压限制：反向电压不超过150V，避免过压击穿；
- 温度控制：PCB布局需预留散热铜箔，避免结温超过150℃；
- 焊接工艺：回流焊峰值温度≤260℃（时间≤10s），波峰焊温度≤250℃（时间≤5s）；
- 存储条件：温度-40℃~+85℃，湿度≤60%，避免腐蚀性气体暴露。
总结
CJ BAR64-02V是一款高性价比PIN二极管，兼具紧凑封装、宽温适应性、低功耗等特点，覆盖射频控制、高速开关、汽车电子等多场景，是中小批量电路设计的可靠选型。
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.
