BAS70肖特基二极管产品概述

BAS70是伯恩半导体(BORN)推出的单通道小信号肖特基二极管,针对低功耗、小体积的电子电路设计,凭借低正向压降、高反向耐压与紧凑封装,广泛适配便携设备、工业控制等场景。以下从核心特性、电气参数、应用场景等维度展开概述。

一、产品核心定位与关键特性

BAS70属于小信号肖特基二极管范畴,区别于大功率整流肖特基,聚焦“低电流、小封装、低功耗”的设计需求,核心特性包括:

  1. 低正向压降:1V@15mA的典型值,导通损耗低,适配电池供电设备;
  2. 高反向耐压:直流反向耐压70V,满足多数低压电路的反向阻断需求;
  3. 紧凑封装:采用SOT-23贴片封装,尺寸仅约2.9×1.6×1.1mm,适配高密度PCB;
  4. 宽温适应性:-40℃~+125℃工作结温,覆盖工业级与消费级环境;
  5. 低反向漏电流:100nA@50V的反向电流,静态功耗极低。

二、电气参数详细解析

BAS70的参数针对小信号电路优化,关键参数需重点关注:

1. 正向特性

  • 正向压降(Vf):典型值1V@15mA,导通时电压损耗低,可延长便携设备续航;
  • 整流电流(If):平均电流70mA,满足小信号电路的连续工作(如偏置、续流);
  • 非重复峰值浪涌电流(Ifsm):100mA(单次),可承受电源启动等瞬态过流,提升可靠性。

2. 反向特性

  • 直流反向耐压(Vr):70V,可阻断反向电压至70V,避免电路击穿;
  • 反向电流(Ir):100nA@50V,即使在50V反向偏置下,漏电流仍处于纳安级,静态功耗可忽略。

3. 温度特性

  • 工作结温范围:-40℃~+125℃,符合工业级器件要求,适配严寒(户外传感器)或高温(车载电子)场景;
  • 存储温度范围:常规肖特基器件支持-55℃~+150℃(需参考具体 datasheet)。

三、封装与典型应用场景

BAS70采用SOT-23贴片封装,引脚定义为:1脚阳极、2脚阴极、3脚空脚(需参考厂商 datasheet),适配自动贴装,生产效率高。

典型应用场景包括:

  1. 便携电子:智能手表、蓝牙耳机、移动电源的电源续流、信号钳位,小封装节省空间;
  2. 工业控制:PLC小信号输入输出、传感器信号处理,宽温适应现场波动;
  3. 射频前端:蓝牙/WiFi模块的信号整流、检波,肖特基高频特性适配射频信号;
  4. 电源保护:低压电源反向保护、过压钳位,70V反向耐压覆盖常见低压场景。

四、可靠性与选型参考

1. 可靠性表现

  • 反向漏电流稳定:100nA@50V在结温范围内变化小,长期工作无功耗上升风险;
  • 浪涌耐受:100mA非重复浪涌可应对电路瞬态脉冲,减少器件损坏;
  • 封装可靠:塑封工艺抗机械应力与腐蚀,适合批量生产与长期使用。

2. 选型参考

  • 电流限制:仅适配平均电流≤70mA场景,大电流需选大功率肖特基(如1N5819);
  • 电压限制:反向耐压70V,高压场景需选高压肖特基或硅二极管;
  • 封装适配:小功率选SOT-23,大功率需选DO-41、SMA等散热封装。

五、品牌与品质保障

BAS70由伯恩半导体生产,该厂商专注功率半导体与小信号器件,产品通过ISO9001认证,符合RoHS环保标准,提供完整 datasheet 与技术支持,适合批量采购。

总结:BAS70凭借低Vf、高反向耐压、小封装与宽温特性,成为小信号电路的优选器件,覆盖便携电子、工业控制等多领域,是低功耗设计的实用选择。

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.

Replenishment inquiry Typical RFQ workflow
