BZT52C11S 产品概述

一、产品简介

BZT52C11S 是江苏长电(CJ)推出的一款独立式稳压二极管,封装为 SOD-323,单只器件提供固定稳压功能。该器件标称稳压值为 11V,属于低功耗、小尺寸的表面贴装稳压二极管,适合对体积和成本敏感的消费电子与便携设备场合。

二、主要电气参数

  • 稳压值(标称):11V
  • 稳压值范围:10.4V ~ 11.6V
  • 最大耗散功率(Pd):200 mW
  • 反向电流(Ir):100 nA @ 8V
  • 阻抗 Zzk:150 Ω(说明器件在某测试条件下的静态阻抗)
  • 阻抗 Zzt:20 Ω(说明在规定工作点下的小信号阻抗)
  • 二极管配置:独立式(单个器件)
    这些参数表明器件适用于微功率参考与过压钳位,反向漏流较小,稳压精度适中。

三、封装与热性能

SOD-323 小尺寸封装便于高密度贴装,但受限于散热能力。标称耗散功率 200 mW 在实际应用中需考虑 PCB 散热条件和环境温度,建议在设计时留有余量并对功率做降额处理。焊接采用常规回流工艺,建议遵循厂商的回流曲线以保证可靠性。

四、典型应用场景

  • 低功耗电压参考与基准源
  • 信号钳位与电压限幅保护
  • 小型便携设备的局部稳压电路
  • 模拟/数字电路中对电压波动的抑制
    在这些应用中,常与串联限流电阻配合使用以控制稳压电流和功耗。

五、使用与注意事项

  • 稳压电路常用公式:R = (Vin - Vz) / Iz,需确保 Iz 在器件允许的功耗范围内。
  • 留意反向漏流随温度上升而增大,温度影响会改变稳压点与功耗分布。
  • 在封装与 PCB 布局上提供合理铜箔以改善散热,并避免在高温环境下长时间满功耗工作。
  • 推荐按厂商规格书进行焊接和存储,避免潮湿引起焊接缺陷。

六、选型建议与可靠性

选型时若需更高稳压精度或更大功率,应考虑更高等级的稳压二极管或小型稳压器。对于对漏电流敏感的电路,需验证在目标工作电压与温度下的 Ir 表现。常规可靠性验证包括焊接热循环、湿热试验与电气参数老化测试,以确保在实际应用中的长期稳定性与一致性。

总结:BZT52C11S 以其 11V 标称稳压、低漏流和 SOD-323 小封装,适合低功耗、空间受限的稳压与钳位场合,设计时应重点关注功率限额与散热管理。

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
