BZT52C5V1 是一款独立式(分立)稳压二极管(Zener),品牌为 Hottech(合科泰),封装为 SOD-123 表面贴装小封装。主要电气参数如下:
计算提示:若在理想散热条件下允许器件承受 Pd=350 mW,则最大持续通过的稳压电流约为 Iz_max ≈ 350mW / 5.1V ≈ 68.6 mA。但实际应用中应做热降额与寿命考虑,通常不建议长期在此极限电流下工作。
SOD-123 为小型表贴封装,适合回流焊工艺。为保证长期可靠性,建议按厂家(Hottech)数据手册提供的回流温度曲线与焊接建议进行操作,并在PCB设计时预留合理的焊盘面积以改善散热。
BZT52 系列型号众多,若需更精确或更大功率,可考虑同系列中标称电压相近但功耗更高或动态阻抗更低的型号;若对泄漏电流、温漂有更高要求,可选择低漏型或精密稳压源(如基准二极管或线性稳压器)。订购与替换时,请以完整型号(BZT52C5V1)、封装(SOD-123)与供应商(Hottech / 合科泰)为准,并参阅最新数据手册确认所有测试条件。
备注:上述参数与计算以产品给定的关键指标为基础,具体设计应以 Hottech 官方 datasheet 与实际测量为准。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
