1N4148WS 是一款面向高频和快速开关场合的小信号开关二极管,BLUE ROCKET 品牌,采用 SOD323 表面贴装封装。该器件在保证开关速度的同时,具有较低的结电容和低反向漏电流,适合各种小信号隔离、整流、钳位和高频切换应用。
1N4148WS 将快速恢复特性与小封装优势结合,适用场景包括但不限于:
SOD323 封装体积小,便于高密度布局,但也带来散热能力受限的问题:
1N4148WS 适合于对体积、速度与低电容有要求的场合;如需更高电流或更强散热,应考虑较大封装或功率型开关二极管;如需更低正向压降可查找肖特基二极管,但肖特基在反向耐压与漏电特性上与硅开关二极管不同,需权衡选择。
BLUE ROCKET 的 1N4148WS 以其小巧的 SOD323 封装、75–100 V 的反向耐压、150 mA 的平均整流能力、8 ns 的快速恢复时间和 5 pF 的低结电容,成为高速开关、小信号整流和高频应用的理想之选。在设计时务必重视热设计和 PCB 布局,以发挥器件的最佳性能与长期可靠性。若需更详细的电气特性曲线、回流工艺参数或封装尺寸图,请咨询 BLUE ROCKET 的技术资料或索取器件数据手册。

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.
