BAS16XV2T1G 产品概述

BAS16XV2T1G 是富芯森美(FUXINSEMI)推出的一款小信号快速开关/整流二极管,采用超小型 SOD‑523 封装,适合空间受限的便携设备和高速开关电路。器件在保持高反向耐压的同时具有极短的反向恢复时间,适合用于高速脉冲、信号整流与保护电路。

一、主要参数概述

  • 正向压降 (Vf):1.25V @ 150mA
  • 直流反向耐压 (Vr):75V
  • 额定整流电流:200mA(连续)
  • 耗散功率 (Pd):150mW
  • 反向电流 (Ir):1μA @ 75V
  • 反向恢复时间 (Trr):6ns
  • 工作结温范围:-55℃ ~ +150℃
  • 非重复峰值浪涌电流 (Ifsm):2A
  • 封装:SOD‑523(超小型表贴)

二、器件特性与优势

  • 小体积、低剖面:SOD‑523 封装非常适合手机、可穿戴和紧凑型消费电子的表面贴装设计,节省 PCB 面积。
  • 高速响应:6ns 的反向恢复时间表明器件用于高速开关或脉冲环境时开关损耗和反向恢复电流较小,利于提高效率与降低干扰。
  • 较高耐压与低漏电:75V 的反向耐压和 1μA 的反向漏电使其可在中低压电源和保护应用中可靠工作。
  • 抗浪涌能力:2A 的单次非重复浪涌能力满足开机冲击或瞬态保护场合的短时电流需求。

三、典型应用

  • 高频整流与检测:用于小功率开关电源中的二次侧整流或高频信号检波。
  • 信号钳位与保护:用于数据与控制线的反向保护、极性保护或钳位用途。
  • 快速开关电路:逻辑级快恢复或级联开关中作为切换/整流元件,减少反向恢复造成的干扰。
  • 便携设备与消费电子:因封装小且漏电小,适用于电池供电系统中的保护电路和功率路径控制。

四、设计与使用注意事项

  • 功耗限制:器件标称耗散功率为 150mW。以给定正向压降计算(1.25V @ 150mA),功耗约为 1.25V × 0.15A = 187.5mW,已超过 150mW 的额定耗散。因此在无额外散热或 PCB 辐射条件下,不建议在 150mA 持续工作状态下长期运行。可按 Pd / Vf 粗略估算连续安全电流:I ≤ Pd / Vf ≈ 150mW / 1.25V = 120mA(近似)。若需要长期 150–200mA 工作,应采用短脉冲模式或在 PCB 设计上提供更好的散热路径,并参考厂家完整规格书的热阻/环境温度余量曲线。
  • 温度对漏电影响:反向电流会随结温上升显著增加,实际电路中高温环境下应考虑漏电导致的静态功耗或偏置误差。
  • 浪涌与脉冲:Ifsm = 2A 表明可承受短时浪涌,但应限定脉冲宽度与重复频率,避免超出热限及导致结温短时升高。
  • 布局建议:尽量缩短引线/走线,减小寄生电感以减少开关瞬变;在需要大的散热能力时,可在焊盘下或周边增设铜箔和过孔以提高热散播(注意 SOD‑523 本身尺寸小,散热能力有限)。

五、封装与焊接建议

  • SOD‑523 为超小型表贴封装,推荐在贴片工艺中使用精确的锡膏量和回流温度曲线,避免过度加热导致元件应力。
  • 由于封装体积小,焊盘尺寸和焊接质量对热传导与电气性能影响明显,建议参考厂家推荐的 PCB 封装尺寸和焊盘图样。
  • 处理时注意静电防护;储存与回流后检查元件外观与焊点完整性。

六、可靠性与环境适应性

  • 宽工作温度范围(-55℃ 到 +150℃)适应多种工作环境,但在高温下器件的最大连续电流能力要相应降额。
  • 长期可靠性受焊接工艺、PCB 散热及运行电流/浪涌条件影响,设计时应留有裕量并进行实际环境的热仿真或加温验证。

总结:BAS16XV2T1G 是一款面向小功率高速开关与保护应用的超小型二极管,具有较高耐压、快速恢复和低漏电特性。其 SOD‑523 封装非常适合空间受限的设计,但需在电流与功耗管理上给予足够重视,合理评估 PCB 散热能力和工作温度,以保证长期可靠运行。若需在高连续电流下使用,建议参照厂方完整数据手册并进行热设计验证。

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.
