BZT52B5V1S 产品概述

一、产品简介

BZT52B5V1S 是扬杰(YANGJIE)推出的一款小型稳压二极管,标称稳压值为 5.1V,适用于对体积与成本敏感的电源基准与过压保护场合。器件采用 SOD-323 小型封装,适合集成到空间受限的消费电子、便携设备与接口保护电路中。

二、电气特性

  • 标称稳压值(VZ):5.1V(稳压范围 5.0V ~ 5.2V)
  • 反向电流(Ir):100 nA @ 0.8V
  • 耗散功率(Pd):200 mW(请注意局部资料描述存在 300 mW 的不一致,应以厂商数据手册为准)
  • 稳态阻抗(Zzt):60 Ω
  • 击穿/动态阻抗(Zzk):480 Ω
    以上参数表明该款稳压二极管在低电流工作点下具有较小的漏电,稳压精度适合一般参考与保护用途,但阻抗较高,不适合承载大电流输出的精密基准需求。

三、封装与热性能

SOD-323 为极小塑封封装,封装热阻较大,器件功耗受限。标称耗散功率 200 mW 是在特定环境温度与PCB散热条件下的额定值,实际使用中应进行功率裕量设计并靠近地平面或铜箔帮助散热,避免连续接近额定Pd。

四、典型应用场景

  • 供电轨的局部基准或微调(低电流)
  • 输入过压保护与钳位(串联限流电阻)
  • 信号线的电压钳位与抗干扰
  • 便携式设备与小型传感模块的低功耗稳压

五、选型与使用建议

  • 若工作电流较大或需要更低输出阻抗,应选择更大功率或专用参考源。
  • 通过串联限流电阻与旁路电容组合,可改善瞬态响应与输出稳定性。
  • 注意环境温度对耗散功率的影响,必要时进行功率去耦与散热评估。
  • 对于精度要求严格的场合,考虑温漂系数与电流依赖性对稳压点的影响。

六、注意事项与资料参考

  • 本概要基于提供的参数整理,个别描述(如 Pd 标称 300 mW)与参数表可能存在矛盾,请以扬杰官方数据手册为准并参照典型特性曲线与测试条件选择使用电流与散热方案。
  • 推荐在设计前下载并阅读厂方完整数据手册,确认最大结温、热阻和测试条件,以保证器件长期可靠运行。

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.

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
