BZX84C24 产品概述
一、产品简介
BZX84C24 是一款独立式稳压二极管，标称稳压值 24V，适用于中低功率电压基准与过压保护场合。器件由 CJ（江苏长电/长晶）生产，采用 SOT-23 小型封装，体积小、易于表面贴装，适合消费电子、工业控制和通信设备中的空间受限设计。
二、主要性能参数
- 稳压值（标称）：24V；稳压范围：22.8V ~ 25.6V。
- 反向电流 Ir：100nA @ 16.8V（低泄漏特性，有利于精密低电流电路）。
- 耗散功率 Pd：300mW（器件最大静态耗散能力）。
- 阻抗：Zzt = 70Ω，Zzk = 250Ω（反映不同工作点下的小信号阻抗特性）。
- 工作结温范围：-55℃ ~ +150℃。
- 封装：SOT-23，便于自动贴片加工。
三、典型应用
- 作为稳压参考源或简单的电压基准；
- 输入保护与过压钳位，用于保护后级电路免受瞬态过压；
- 偏置与电流限制电路，常见于传感器接口、放大器偏置网络。
四、封装与热管理
SOT-23 封装导热有限，Pd 为 300mW 时需关注 PCB 热散逸。建议在 PCB 上增加散热铜箔或通过热过孔扩展散热区域，避免长时间在高结温下工作以延长可靠性。
五、设计注意事项与推荐
- 选择工作点时注意稳压二极管的阻抗和漏电流对电压精度的影响，低电流时阻抗较大，稳压精度下降；
- 对于重复或脉冲过压场合，应核算瞬时功率并适当增加限流措施；
- 在高温环境中需按热阻和结温极限进行功率降额。
六、可靠性与采购信息
CJ（江苏长电/长晶）品牌，质量与国产供应链稳定。订购时请确认完整料号 BZX84C24、封装 SOT-23 及包装方式（卷带/管装），并关注元件批次和出厂测试报告以满足关键应用的可靠性要求。

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.
