BZT52B4V7 稳压二极管产品概述
一、产品简介
BZT52B4V7 是扬杰（YANGJIE）出品的一款独立式稳压二极管，标称稳压值 4.7V，常用于低功耗电压基准与过压保护场合。器件采用 SOD-123 小封装，体积小、焊接方便，适合表面贴装工艺。
二、主要参数
- 稳压值（标称）：4.7V
- 稳压值范围：4.61V ~ 4.79V
- 反向电流 Ir：5 μA @ 2.0V
- 最大耗散功率 Pd：500 mW
- 稳压阻抗 Zzt：78 Ω
- 斜率阻抗 Zzk：500 Ω
- 工作结温范围：-55 ℃ ~ +150 ℃
- 配置：独立式（二极管单只）
- 封装：SOD-123
三、性能特点
- 精度较高：4.61～4.79V 的稳压范围适合对电压偏差有一定要求的应用。
- 低漏电：2V 时反向电流仅 5 μA，有利于电池供电与待机电路的低功耗设计。
- 小封装高集成度：SOD-123 适合空间受限的消费类与工业电子产品。
- 温度范围宽：可在 -55 ℃ 至 +150 ℃ 的环境工作，可靠性高。
四、典型应用
- 低功耗电压基准与偏置源
- 电源的过压保护与电压钳位
- 测试与测量电路的小电流稳压场景
- 消费电子、通信设备、便携式仪器等
五、使用与注意事项
- 功耗限制：Pd 为 500 mW，设计时需计算在最大工作电压/电流下的耗散，防止超过额定功耗。
- 热管理：SOD-123 散热依赖 PCB 走铜，建议在热敏感应用中增加散热铜箔或采用热垫连接。
- 反向工作：稳压二极管在反向击穿区稳定工作，正向导通时按普通二极管处理，注意极性安装。
- 环境可靠性：高温或长期高功耗运行应考虑结温上升并进行降额使用。
六、典型电路与设计建议
- 作为并联稳压元件时，常与限流电阻串联：Vin -> R -> 节点 -> 负载；节点并联 BZT52B4V7 到地，用以钳位电压。
- 选择 R 时需确保在最坏情况下稳压二极管所承受的功耗不超过 500 mW，同时在最低输入电压下仍有足够电流维持稳压。
- 注意动态阻抗（Zzt）对稳压精度的影响：在负载或信号变化时，高阻抗会导致电压漂移，应在需要较好瞬态响应的场合评估合适的偏置电流。
七、封装与选购提示
- SOD-123 便于高速贴装与回流焊流程，订购时注意是否为单端卷带或切带包装以匹配贴片设备。
- 检索型号时以 BZT52B4V7 / YANGJIE 标识为准，注意供应商给出的完整规格书以确认测试条件与典型特性。
本器件适合用于对体积、成本与能耗有要求的稳压与保护场景。设计时请结合实际电路工作点与 PCB 散热条件，必要时参考厂商详细规格书与测试曲线以获得最佳性能。

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.
