BAT64-05(江苏长电CJ)肖特基二极管产品概述

一、产品定位与核心属性

BAT64-05是江苏长电科技(CJ) 推出的一款1对共阴极肖特基二极管,属于小功率通用型器件,核心围绕「低功耗、快速响应、小型化」三大需求设计,适配消费电子、工业控制、通信等领域的低压小电流场景。

二、关键电气参数深度解析

BAT64-05的参数平衡性能与可靠性,核心参数如下:

2.1 正向特性

  • 正向压降(Vf):750mV@100mA(典型值),远低于普通硅二极管(约700mV~1V),且随电流变化平缓(200mA时约850mV),可有效降低整流回路损耗;
  • 额定整流电流:250mA,满足大多数小功率设备的持续工作需求(如5V/3.3V电源二次整流)。

2.2 反向特性

  • 直流反向耐压(Vr):40V(额定值),覆盖常见低压电路的反向电压场景(如电池反接保护、信号反向干扰);
  • 反向漏电流(Ir):2μA@25V(25℃时),漏电流极小,适合低功耗设计(如电池供电设备),避免静态功耗过高。

2.3 浪涌与可靠性

  • 非重复峰值浪涌电流(Ifsm):800mA(单次脉冲≤10ms),具备一定瞬间过载能力,可应对电路启动时的瞬时电流冲击。

三、封装与引脚配置

采用SOT-23-3封装(尺寸约1.6mm×1.0mm×0.8mm),体积紧凑,适配高密度PCB设计(如智能手环、蓝牙耳机等便携设备)。

引脚配置(共阴极):

  • 引脚1:阳极1(Anode 1);
  • 引脚2:阴极(Cathode,公共端);
  • 引脚3:阳极2(Anode 2); 该配置可同时实现两路独立整流/钳位,简化电路设计。

四、典型应用场景

结合参数特性,BAT64-05主要应用于:

4.1 低压直流电源整流

适用于5V/3.3V电源的二次整流(如USB充电、移动电源输出),低压降提升转换效率。

4.2 信号过压保护

共阴极配置可同时钳位SPI、I2C等高速总线信号,当电压超限时导通泄放电流,保护后端IC。

4.3 开关电路续流

作为小功率MOSFET/三极管的续流二极管,肖特基的快速恢复特性(反向恢复时间<10ns)减少反向损耗,提升开关效率(如LED驱动、小型电机控制)。

4.4 电池管理

用于电池反接保护(正向导通、反向截止)或充电回路整流,低漏电流延长电池待机时间。

五、选型优势对比

相较于同类产品,BAT64-05具备:

  1. 更低损耗:750mV@100mA,比竞品低50mV+,功率损耗降低10%~15%;
  2. 稳定漏电流:2μA@25V,仅为部分硅二极管的1/10,适合低功耗场景;
  3. 高性价比:长电CJ供应稳定,可替代进口品牌(如NXP、ON同类产品);
  4. 小封装兼容:SOT-23-3适配多数小型化PCB,无需额外布局调整。

六、使用注意事项

为确保可靠性,需注意:

  1. 反向电压≤40V,持续正向电流≤250mA;
  2. 单次浪涌电流≤800mA(≤10ms);
  3. 焊接温度:回流焊≤260℃(≤10s),波峰焊≤240℃(≤5s);
  4. 静电防护:肖特基对静电敏感,需用ESD防护措施(防静电袋、接地工作台);
  5. 工作温度:-55℃~125℃(工业级),满足多数环境需求。

总结

BAT64-05作为长电CJ的小功率共阴极肖特基二极管,凭借低压降、快速开关、小封装、高可靠性等特点,是低压小电流场景(整流、保护、续流)的理想选型,广泛覆盖消费电子、工业控制等领域,性价比突出。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
