BZT52C3V6 产品概述

一、型号与基本特性

BZT52C3V6 是一款独立式小功率稳压二极管(Zener),标称稳压值 3.6V,允许范围 3.4V~3.8V。器件以 SOD-123 表面贴装封装提供,由 YONGYUTAI(永裕泰)生产,适用于空间受限的低功耗稳压与电压保护场合。主要电气参数包括:反向漏电流 Ir = 5 μA(在 1V 条件下测得),稳压阻抗 Zzt ≈ 90 Ω,最大耗散功率 Pd = 500 mW。

二、功能与应用场景

  • 作为低功耗电压基准或本地稳压源,用于为小信号电路、传感器或门电路提供简单可靠的参考电压。
  • 用作电压箝位与过压保护,保护输入端或敏感器件免受瞬态或过高电压冲击。
  • 在电源监测、偏置网络、模拟前端等场合提供成本低、布局简单的解决方案。
  • 适合消费电子、工业控制、仪表和小型通信设备等需要节省空间与成本的产品。

三、关键电气参数说明

  • 稳压值:3.6V(典型),允许偏差 3.4V~3.8V,应根据所需精度选择器件或加以校准。
  • 反向电流:5 μA@1V,表示在低电压偏置下漏流较小,利于低功耗应用和高阻输入电路。
  • 稳压阻抗:90 Ω,提示在工作电流变化时输出电压会有较明显的摆动,适合对稳压精度要求不高的场景。
  • 耗散功率:500 mW,理论上的最大稳态电流可估算为 Imax ≈ Pd / Vz ≈ 500 mW / 3.6 V ≈ 139 mA,但实际受限于封装散热能力,应保守设计,通常工作电流保持在数 mA 到几十 mA 范围内以保证长期可靠性。

四、典型电路与设计要点

  • 常用串联限流电阻实现稳压:选择 R = (Vin - 3.6V) / Iz(Iz 为稳压工作电流),并确保 (Vin - 3.6V) × Iz / Vin 不超过 Pd。
  • 由于 Zzt 较高,输出在电流变化下电压波动较明显,建议在需要更稳定参考时并联低噪电容或改用低阻抗参考源。
  • 注意反向漏流对高阻输入的影响,在微安量级电路应考虑漏流引起的偏差。

五、封装与焊接注意事项

SOD-123 为常见小尺寸表面贴装封装,便于自动贴装与回流焊工艺。焊接时应遵循厂商推荐的回流温度曲线,避免过长高温暴露以保护器件性能;手工焊接应尽量缩短加热时间。储存与防静电保护按常规半导体器件要求处理。

六、选型与可靠性建议

  • 若系统对稳压精度、温度系数或噪声有较高要求,建议选用精密参考源或低阻抗大功率稳压二极管。
  • 在功率接近器件 Pd 时,应考虑散热与环境温度影响,预留安全裕度(一般不超过额定功率的 50%~70% 连续工作)。
  • 采购时确认批次与原厂出货信息,必要时索取曲线资料(I-V、阻抗随电流变化、温度特性)以用于详细仿真与设计验证。

七、总结

BZT52C3V6(YONGYUTAI,SOD-123)是一款适合低功耗、占板面积小的通用稳压二极管,适用于简单电压参考、过压保护与偏置电路。其低漏电流和中等稳压阻抗特性决定了它在成本敏感且精度要求不高的应用中具有良好性价比;在高精度或高功率场合应谨慎选型或采取额外设计措施。

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.
