BAS116L2B-TP 产品概述

BAS116L2B-TP 是美微科(MCC)推出的一款小型 Schottky 二极管,采用 DFN1006-2L 超小封装,针对高反向耐压与低漏电、高速开关场景做了优化。器件在宽温区间内保持稳定的电气特性,适合用于便携式电源管理、信号整流与保护电路等对体积和效率有较高要求的应用。

一、主要电气参数(关键指标一览)

  • 工作结温范围:-65℃ ~ +150℃
  • 正向压降(Vf):1.25 V @ 150 mA
  • 直流反向耐压(Vr):85 V
  • 整流电流(If):215 mA
  • 非重复峰值浪涌电流(Ifsm):4 A
  • 耗散功率(Pd):300 mW
  • 反向电流(Ir):5 nA
  • 反向恢复时间(Trr):3 μs

以上参数为器件的典型/最大评分值,应在具体电路设计时结合实际工况与PCB热阻进行评估与余量设计。

二、性能特点与优势

  • 小封装、高耐压:DFN1006-2L 封装占板面积小,同时器件具备高达 85 V 的反向耐压,适合较高电压场合的低电流整流和保护。
  • 低正向压降:在 150 mA 电流工况下 Vf 约为 1.25 V,有助于降低导通损耗,提高系统效率(尤其在低功率开关电源、能量采集等应用)。
  • 极小的反向漏电:5 nA 的反向电流在高温与高压下仍有良好表现,适用于需低静态功耗的电池供电或待机电路。
  • 瞬态耐受能力:4 A 的非重复峰值浪涌能力能应对短时过流或开关浪涌,提升系统可靠性。
  • 快速开关特性:3 μs 的反向恢复时间有助于在开关频率较低的场合减少开关损耗与电磁干扰。

三、典型应用场景

  • 便携式电源与电池管理:作为充放电保护、低压差整流器件,在体积受限的产品中可有效降低能耗并节约PCB空间。
  • 电源反向保护与极性保护:利用其低正向压降与高反向耐压特性,防止误接电源反向造成损坏。
  • 低功率开关电源与降压整流:在次级整流、回收二极管或旁路保护中表现良好。
  • 信号线路保护与二级保护:结合低漏电特性,适合高阻抗信号路径的保护或隔离应用。

四、封装与机械特性

  • 封装:DFN1006-2L(超小型双引脚无引线封装)
  • 尺寸优势:极小的占板尺寸适合高密度电路设计,但相应的散热能力受限,需要充分考虑PCB铜箔面积与过孔布局以提高热扩散。
  • 焊接兼容性:支持常规回流焊工艺,建议按制造商回流曲线进行温度档位控制,避免过热导致封装或焊点损伤。

五、热管理与可靠性建议

  • 额定耗散功率为 300 mW,在实际使用中应考虑到封装与 PCB 的热阻,若长期工作电流接近额定整流电流,需在 PCB 上增加散热铜箔或热平面以降低结温。
  • 建议在高环境温度或高开启率应用中引入温度余量设计,避免长期运行在器件极限条件下以提升可靠性。
  • 对于频繁冲击或高浪涌环境,考虑使用额外浪涌抑制元件(如 TVS)配合使用,以延长器件寿命。

六、选型与使用注意事项

  • 请在设计中核对最大结温和实际结温,确保在任何工作条件下器件结温不超过 +150℃。
  • 正向压降随电流与温度变化明显,设计时应参考典型 Vf 曲线并预留能耗余地。
  • 若应用中有更高频率的开关需求或需更低恢复时间,应评估是否选择更低 Trr 的专用快恢复或肖特基变体。
  • 在订购与替换时确认封装代码(DFN1006-2L)与厂商型号 BAS116L2B-TP,避免与外形或参数相近但电气特性不同的型号混淆。

结语:BAS116L2B-TP 以其高耐压、低漏电与超小封装特性,适合对体积敏感且需高反向耐压的低功率整流或保护场景。在实际设计中,建议结合 PCB 散热设计与精确工况评估,以发挥器件最佳性能并保证长期可靠性。若需进一步的封装尺寸图、典型特性曲线或可靠性测试报告,可咨询供应商或参考官方数据手册。

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.
