BAS116 产品概述

一、概述

BAS116 是一款面向中小电流应用的独立式二极管(SOT-23 封装),由 BORN(伯恩半导体)提供。器件以低正向压降、极低泄漏和针对瞬态保护优化的结构为设计出发点,适用于开关、整流及瞬态抑制等场景。器件工作结温范围宽(-55℃ 至 +150℃),兼顾工业级可靠性与小型化封装的实用性。

二、主要规格

  • 封装:SOT-23,单只独立二极管封装
  • 耗散功率(Pd):200 mW
  • 最大整流电流(Io):200 mA
  • 直流反向耐压(Vr):75 V
  • 正向压降(Vf):1.25 V @ 150 mA
  • 非重复峰值浪涌电流(Ifsm):2 A
  • 反向电流(Ir):5 nA(典型,室温)
  • 反向恢复时间(Trr):约 3 ns(恢复特性极短)
  • 工作结温:-55℃ ~ +150℃

以上参数为典型/最大等级指标,具体应用中请参考实际样片测试或厂方晶圆数据表以获得完整电气特性曲线。

三、关键特性

  • 低正向压降:在较高的整流电流下仍保持较低 Vf,有助于降低功耗及热升。
  • 瞬态保护环结构:封装/芯片级设计对高频瞬态有良好抑制能力,适合对输入瞬变有要求的场合。
  • 可忽略的反向恢复:极短的反向恢复时间(约 3 ns)使其在中速开关应用中可减少反向恢复引发的干扰和额外损耗。
  • 低反向电容与极低漏电流:有利于高阻/高频前端、信号路径的保持信号完整性、降低偏置误差。
  • 中速开关性能:在开关频率不极端偏高时可获得可靠的切换表现,适合通用中速数字/模拟电路。

四、典型应用

  • 保护与钳位:输入反向保护、信号钳位、浪涌钳位(配合抑制元件使用)
  • 二极管整流:小电流整流与反向保护场合
  • 开关电源与隔离电路:整流/恢复二极管(中小功率段)
  • 信号与射频前端:低电容与低漏电特性适合用于敏感信号路径的整流/保护
  • 便携设备与消费电子:体积受限、需降低功耗与热量的场合

五、封装与热管理

SOT-23 小封装方便于表面贴装和高密度电路设计,但热阻相对较高,器件额定耗散功率 200 mW 是在良好散热条件下在环境温度下的典型值。实际设计中建议:

  • 将二极管放置于靠近受保护节点的位置以缩短寄生路径;
  • 保持焊盘和地平面良好连接以利散热,可在必要时通过铜箔加大散热区域或使用过孔连接到内层/底层散热铜箔;
  • 在高环境温或高占空比应用中,按结温上升进行降额使用,避免长期在极限 Pd 下运行。

六、使用建议与注意事项

  • 在需要承受高瞬态能量的场合,建议与合适的瞬态抑制器(TVS)并用,以分担瞬态能量;
  • 注意正向特性随电流非线性上升,若长期在 150 mA 附近工作,应评估温升与热阻;
  • 对关键信号路径,利用其低电容和低漏电特性,但对极高频或极高精度测量电路,仍建议参考实际测试数据;
  • 焊接与回流:遵循常规 SMD 回流工艺,避免超出器件允许的最高结温与暴露时间;取样验证可靠性与焊接后的电气特性变化。

七、订购与替代件建议

  • 品牌:BORN(伯恩半导体),型号 BAS116,封装 SOT-23。
  • 在选型时可参考同类低 Vf、低漏电、75 V 等级的中小电流硅/肖特基二极管作为替代件,但需比对正向压降、反向泄漏、反向恢复和封装脚位以保证功能互换。
  • 建议在批量采购前索取样品并做环境与电气完整性测试,确保在目标应用中满足长期可靠性要求。

结语:BAS116 以低压降、低漏电和快速恢复为主要卖点,适合体积受限且对瞬态和开关性能有一定要求的中小电流场合。合理的 PCB 布局与热设计能显著提高其工作稳定性与寿命。

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.
