BZT52C4V3是台湾迪嘉(TWGMC)推出的一款小型表面贴装稳压二极管,采用SOD-123封装,专为低功率、高密度电路的稳压及参考电平需求设计。产品具备宽温范围、低漏电流等特性,可广泛应用于消费电子、工业控制及物联网等领域。
该型号属于独立式稳压二极管,核心功能为通过反向击穿特性提供稳定电压输出。品牌为TWGMC(台湾迪嘉),型号标识对应明确:
封装采用SOD-123超小型表面贴装结构,典型尺寸约2.0mm×1.25mm×1.0mm,适配高密度PCB布局,同时支持自动贴装(SMT)工艺,降低生产难度。
产品电性能经标准化测试,关键指标清晰:
SOD-123封装具备三大优势:
宽温范围是核心可靠性亮点,可在汽车电子(部分场景)、工业传感器、户外设备等极端温度下稳定工作。
BZT52C4V3参数适配性强,覆盖以下典型场景:
作为辅助稳压元件,为3.3V系统提供4.3V微调基准,或用于小型电源模块输出稳压。
为比较器、ADC(模数转换器)、DAC(数模转换器)提供稳定4.3V基准,确保信号采集与转换精度。
利用反向击穿特性,过压时快速导通钳位至4.3V左右,保护MCU、传感器等敏感元件。
低漏电流(3uA@1V)、小功耗(500mW)适配智能手环、无线传感器节点等低功耗设备。
-55℃~+150℃宽温范围适配PLC、电机驱动电路的辅助稳压或保护需求。
稳压范围4.0V~4.6V、动态阻抗90Ω,适合±7%精度需求;若需更高精度,需选带温度补偿的基准二极管(如LM4040)。
同参数同封装可替代型号:飞利浦BZX84C4V3、国巨ZMM4V3、旺诠RS1C4V3等。
BZT52C4V3是一款性价比高、参数均衡的小型稳压二极管,适合中小功率电路的稳压、参考及保护需求,宽温范围与小封装使其在工业及消费电子领域具备广泛应用潜力。

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.
