BZX84C5V1 产品概述

概要

BZX84C5V1 是由先科(ST)公司生产的一款稳压二极管,属于BZX84系列。该系列稳压二极管广泛应用于各种电子设备中,用于提供稳定的电压输出,保护电路免受过电压的损害。

基础参数

  • 二极管配置: 独立式
  • 功率(Pd): 350 mW
  • 反向电流(Ir): 2 μA @ 2 V
  • 商品分类: 稳压二极管
  • 稳压值(标称值): 5.1 V
  • 稳压值(范围): 4.8 V ~ 5.4 V
  • 阻抗(Zzt): 60 Ω

封装和外观

BZX84C5V1 采用 SOT-23 封装,这是一种小型化的封装形式,适合于现代电子产品的紧凑设计需求。SOT-23 封装具有三个引脚,分别为阴极、阳极和基准点(如果需要),使其在 PCB 布局中更加灵活。

功能特点

稳压功能

BZX84C5V1 的主要功能是提供一个稳定的输出电压,标称值为 5.1 V,实际工作范围在 4.8 V 到 5.4 V 之间。这意味着无论输入电压如何变化,只要在规定范围内,BZX84C5V1 都能维持一个相对稳定的输出电压。

低反向电流

该稳压二极管在反向偏置下具有极低的泄漏电流(仅 2 μA @ 2 V),这对于节能和降低热量产生非常重要。低反向电流也意味着在正常工作条件下,设备的能量消耗会更少。

高功率处理能力

尽管体积小巧,但 BZX84C5V1 具有较高的功率处理能力,最大可达 350 mW。这使得它能够在各种应用场景中承受一定的负载和过载情况。

低动态阻抗

动态阻抗(Zzt)为 60 Ω,这表明当输入电压变化时,输出电压的波动会相对较小,从而提供更稳定的输出。

应用场景

电源稳压

BZX84C5V1 可以用于简单的电源稳压模块,确保输出电压保持在 5.1 V ±10% 的范围内,适用于需要稳定电源的电子设备。

过电压保护

由于其稳压特性,BZX84C5V1 也可以作为过电压保护元件。当输入电压超过设定值时,它会将多余的能量转换为热能,从而保护后级电路。

参考电压源

在一些需要精确参考电压的应用中,如模拟电路或数字电路中的参考电压源,BZX84C5V1 都可以提供一个可靠且稳定的参考点。

使用注意事项

  • 热管理: 尽管 BZX84C5V1 有一定的功率处理能力,但在高负载或高温环境下,仍需要进行适当的散热设计,以确保其可靠运行。
  • 电路布局: 由于 SOT-23 封装较小,布局时应注意引脚间距和周围元件的布置,以避免短路或其他问题。
  • 输入输出匹配: 确保输入电压在稳压二极管的工作范围内,并且输出负载符合其最大功率限制。

总结

BZX84C5V1 是一款功能强大、体积小巧的稳压二极管,适用于广泛的电子应用场景。其稳定的输出电压、低反向电流和高功率处理能力,使其成为许多设计师和工程师的首选元件。通过合理的使用和布局,这款稳压二极管可以为您的电子产品提供可靠且高效的电源解决方案。

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
