BAV21WT 是 SHIKUES(时科)推出的一款独立式开关二极管,采用超小型 SOD-523 封装,专为高速开关和一般小信号整流场合设计。该器件具备高达 200V 的直流反向耐压与较低的正向压降,反向漏电流极小,反向恢复时间短,适合在体积受限、要求快速切换和高耐压的电路中使用。
主要特性一览:
BAV21WT 的电气参数强调高耐压与低漏电,适用于高压小信号应用:
需要特别注意功率限制:额定耗散功率 Pd = 200mW。在 IF = 200mA、Vf = 1.25V 的条件下,器件瞬时耗散功率约为 250mW(Vf×IF),已超过 Pd 标称值。因此在连续工作或长期使用时,应通过降低平均电流、采用脉冲工作模式、或优化热设计来保证安全余量。
总结:BAV21WT(SHIKUES 时科)以其小巧的 SOD-523 封装、200V 耐压、低漏电与较快恢复速度,适合高密度电路中的高压小信号开关与保护用途。设计时应重点关注热管理与平均功耗,以确保长期可靠运行。

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.
