BAT46W 为 Hottech(合科泰)供应的一款高耐压、低电流整流二极管,采用 SOD‑123 小型表面贴装封装。该器件针对低功耗、空间受限的便携与消费电子设计,提供高达 100V 的直流反向耐压能力和良好的浪涌承受能力,适合用于低电流整流、反向保护与信号整形等场景。
注:正向压降给出的是在 250 mA 下的测试值,超过器件连续额定整流电流(150 mA)。实际设计中应以连续额定电流和工作温度条件为依据进行热设计与电气裕量评估。
BAT46W 采用 SOD‑123 小型表面贴装封装,特点是体积小、引脚间距紧凑,便于高密度 PCB 布局。SOD‑123 的热阻和散热面积较小,因此在接近或超过额定电流时,结温上升较快,需要在 PCB 布局时考虑散热处理(如增加铜箔面积、靠近散热层或通过热沉过孔将热量扩散到内部层)。
典型布板建议:
如需进行电路级仿真或热仿真(结温推导、PCB 散热优化),建议提供具体的工作电流、占空比及环境温度,我可以基于这些数据给出更精确的使用建议与 PCB 布局优化要点。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
