1N4148HS 是晶导微电子推出的一款高速开关二极管,采用小型 SOD-323HE 封装,面向空间受限的高速信号与保护电路。该器件在 150mA 工作电流下正向压降仅为 1.25V,反向漏电流极小,反向恢复时间仅 4ns,适合高频开关与脉冲应用。
1N4148HS 在 150mA 条件下 Vf≈1.25V,适用于中小电流级的开关场景。100V 的反向耐压提供了充足的安全裕量,可用于 12V/24V 系统及更高电压的信号隔离场合。Ir=1μA(75V)代表低漏电,适合高阻抗和精密模拟电路。Trr=4ns 表示器件可胜任 MHz 级别的开关频率与窄脉冲处理。
SOD-323HE 为微型封装,热阻相对较大。建议:
型号:1N4148HS
品牌:晶导微电子
封装:SOD-323HE(微型表面贴装)
订购时请确认完整料号与包装形式(卷带/管装),并索取最新数据手册以获取电气曲线、热阻与回流焊工艺详情。

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.
