BAS21S 产品概述

概要

BAS21S 是由友台半导体(UMW)生产的一种高性能开关二极管,采用1对串联式的配置。这种二极管专为高速开关应用而设计,具有优秀的电气特性和可靠性。

基础参数

  • 二极管配置: 1对串联式
  • 反向恢复时间(trr): 50ns
  • 反向电流(Ir): 100nA @ 200V
  • 商品分类: 开关二极管
  • 整流电流: 200mA
  • 正向压降(Vf): 1.25V @ 200mA
  • 直流反向耐压(Vr): 250V

包装和封装

BAS21S 采用 SOT-23 封装,这是一种小型化的封装形式,适合于现代电子设备中的空间有限场景。SOT-23 封装不仅节省了空间,还提高了设备的集成度和可靠性。

电气特性

反向恢复时间(trr)

BAS21S 的反向恢复时间仅为 50ns,这使得它非常适合高速开关应用。快速的反向恢复时间可以减少开关过程中的能量损耗,并提高系统的总体效率。

反向电流(Ir)

在 200V 的工作条件下,BAS21S 的反向电流仅为 100nA。这表明该二极管具有极好的绝缘性和低漏电特性,确保在正常工作状态下不会发生不必要的能量损耗。

整流电流

BAS21S 支持最大整流电流为 200mA,这使得它能够满足中小功率电子设备的需求。这种整流能力使其广泛应用于各种消费电子产品、工业控制设备和汽车电子系统中。

正向压降(Vf)

在 200mA 的工作条件下,BAS21S 的正向压降为 1.25V。这是一个相对较低的值,意味着在正常工作状态下,二极管不会产生过多的热量,从而提高了系统的总体效率和可靠性。

直流反向耐压(Vr)

BAS21S 具有 250V 的直流反向耐压,这使得它能够承受较高的反向电压,确保在各种应用场景中都能保持稳定运行。这种高耐压特性使其特别适合于需要处理高电压信号的系统。

应用场景

  1. 高速开关电路: 由于其快速的反向恢复时间和低正向压降,BAS21S 非常适合用于高速开关电路,如高频逆变器、电源管理模块等。

  2. 信号处理: 在信号处理应用中,BAS21S 可以用于信号整形、峰值检测以及其他需要快速响应和低噪声的场景。

  3. 汽车电子: 由于其高耐压特性和小型化封装,BAS21S 也广泛应用于汽车电子系统,如车载电源管理、传感器接口等。

  4. 消费电子: 在消费电子产品中,如手机、平板电脑等,BAS21S 可以用于电源管理、信号处理以及其他需要高性能开关二极管的场景。

优势

  • 高速开关能力:快速的反向恢复时间使其适合于各种高速应用。
  • 低能耗:低正向压降和低反向电流减少了能量损耗,提高了系统效率。
  • 高耐压性:250V 的直流反向耐压确保了在高电压环境中的稳定运行。
  • 小型化封装:SOT-23 封装节省空间,提高了设备集成度。

总结

BAS21S 是一种高性能开关二极管,通过其优秀的电气特性和小型化封装,广泛应用于高速开关电路、信号处理、汽车电子以及消费电子等领域。其快速的反向恢复时间、低正向压降和高耐压性使其成为这些应用场景中的理想选择。友台半导体(UMW)对该产品的严格质量控制和可靠性保证,也使得它在市场上具有竞争力。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
