BAS21C 产品概述
概述
BAS21C 是一种经过优化的开关二极管，专为高开关频率应用而设计，广泛应用于各种电子设备中。其独特的共阴极配置和优良的电气特性，使其成为许多电路设计的理想选择。由知名半导体制造商 UMW（友台半导体）推出，BAS21C 具有良好的性能表现，适合各种用途，如信号整流、开关控制和电源管理。
电气特性
- 反向耐压（Vr）：BAS21C 的直流反向耐压达到 250V，这使得它能够在高压环境中稳定工作，抵御意外的反向电压冲击。
- 整流电流（If）：该二极管的整流电流额定值为 200mA，能够有效处理常见的电流需求，非常适合中等负载的应用场合。
- 正向压降（Vf）：在 200mA 的正向电流情况下，BAS21C 的正向压降为 1.25V。这一特性在设计时至关重要，因为它直接影响到整体电源效率和耗散热量。
- 反向恢复时间 (trr)：快速的反向恢复时间为 50ns，使其能够在高频率操作下有效工作，确保在切换操作中快速响应。
可靠性和耐用性
BAS21C 的反向电流 Ir 在 200V 时仅为 100nA，这表明其在静态条件下的低泄漏特性，提升了整体电路的稳定性和可靠性。此外，封装采用 SOT-23 尺寸，使得该二极管能够在密集电路板应用中占用更少的空间，同时保证了良好的散热能力。
应用场景
BAS21C 的设计非常适合以下应用：
- 开关电源（Switching Power Supply）：因其较高的反向耐压和快速的开关特性，适用于开关电源和DC-DC转换器中。
- 信号整流：可用于音频设备的信号整流，确保信号的完整性和低失真。
- 保护电路：作为过压保护元件，可以在意外的高电压情况下及时切断电流，保护后续电路器件。
- 通信设备：在射频和数据通信设备中，快速的反向恢复时间有助于高频信号的快速切换。
封装特性
BAS21C 采用 SOT-23 封装，此封装外形小巧、易于自动化贴装，并具备良好的散热性能。SOT-23 封装能够适应不同的电路板设计要求，非常适合现代电子产品对小型化和高密度设计的需求。
总结
BAS21C 是一款高性能的开关二极管，凭借其出色的电气特性和可靠性，成为设计工程师的首选组件。无论是在开关电源、信号整流，还是在保护电路方面，其卓越的性能都使得其在众多应用场景中表现出色。通过选择 BAS21C，您可以确保您的设计在性能、稳定性和小型化方面都达到最佳效果。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
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.
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.
