BAT46WS 肖特基二极管(晶导微电子)产品概述

一、产品简介

BAT46WS 是晶导微电子推出的一款小信号肖特基二极管,采用 SOD-323 表面贴装封装。器件以低正向压降、快速响应与低反向漏电为特色,适用于高频整流、钳位保护与小信号检波等场合。工作结温范围宽(-55℃ 至 +125℃),适合工业级电子设计需求。

二、主要特点

  • 低正向压降:Vf = 1.0 V(在 If = 250 mA 条件下),降低导通损耗,有利于提高效率并减少发热。
  • 低漏电流:Ir = 2 μA(在 Vr = 75 V),在高压反向偏置下保持较小的漏流,利于保持电路静态性能。
  • 良好浪涌能力:非重复峰值浪涌电流 Ifsm = 25 A,能够承受短时的过载或浪涌脉冲(用于吸收突发能量)。
  • 额定耐压高:直流反向耐压 Vr = 100 V,适用于中低电压整流与保护场合。
  • 连续整流电流:150 mA,适合小功率整流和信号处理应用。
  • 封装:SOD-323,体积小,便于高密度表贴组装。

三、关键参数(便于快速查阅)

  • 品牌:晶导微电子
  • 型号:BAT46WS
  • 正向压降:1 V @ 250 mA
  • 直流整流电流:150 mA
  • 非重复峰值浪涌电流:25 A
  • 直流反向耐压:100 V
  • 反向电流:2 μA @ 75 V
  • 工作结温:-55 ℃ ~ +125 ℃
  • 封装:SOD-323

四、典型应用

  • 高频整流与信号检波(如小功率开关电源辅助整流、射频检波电路)
  • 反向极性、浪涌与瞬态电压钳位保护(输入保护、耦合线路保护)
  • 电平移位、开环整流、逻辑电路中的低压降路径设计
  • 便携设备与消费电子中对体积和效率有要求的小功率整流场合

五、封装与安装建议

  • SOD-323 封装适合自动贴片与回流焊工艺,建议采用标准的无铅回流温度曲线进行焊接。
  • 由于器件额定连续整流电流不大(150 mA),请在 PCB 布局时为二极管提供足够的铜箔散热路径,必要时在焊盘附近增加铜面或底层散热通孔以改善热阻。
  • 布线建议:引脚短且宽,尽量缩短热源与器件之间的距离,避免长细铜线增加热阻。

六、可靠性与注意事项

  • 在使用 Ifsm 指标时注意这是非重复峰值波形能力,仅用于短时浪涌(例如浪涌启动或碰撞脉冲),不宜长期反复承受高幅值浪涌。
  • 在高温环境下(接近 +125 ℃)应对工作电流进行降额设计,以保证长期可靠性。正向功耗近似为 P = Vf × I,典型满载(150 mA)下器件耗散约 0.15 W,结合封装与 PCB 散热能力评估结温。
  • 储存与装配时遵守潮湿敏感度和常规静电防护措施,避免因潮气或静电导致的损伤。

七、选型建议与结语

BAT46WS 适合对体积、速度与低压降有要求的低功率应用,且在较高反向电压场合仍能保持低漏电与良好浪涌能力。若设计需更高的连续电流或更低的 Vf,可考虑更大封装或同类功率级别的肖特基器件;若需要更高耐压或更低漏电,则需在器件规格中进一步对比选择。总体而言,BAT46WS 在 SOD-323 体积下提供了均衡的电气性能,是便携、工业级小功率整流与保护电路的实用选择。

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.
