PDZ27BGWJ是Nexperia(安世半导体) 推出的独立式稳压二极管,核心功能为提供稳定的27V(标称值)参考电压,属于中高压稳压管范畴。该器件采用SOD-123表面贴装封装,兼顾小尺寸、低功耗与可靠性,适用于工业控制、消费电子、通信设备等多领域的电路设计。
PDZ27BGWJ的参数针对稳压性能、功耗及稳定性做了针对性优化,关键参数解析如下:
标称稳压值为27V,实际工作范围为26.19V~27.53V,精度控制在±3%以内(基于标称值计算)。该范围确保批量器件的电压一致性,减少电路调试时的分压补偿成本,适合对电压精度要求较高的场景。
反向漏电流为50nA@21V(反向电压21V时),远低于普通稳压管的典型μA级漏电流,说明器件反向截止特性优异。低漏电流可有效降低电路静态功耗,适配对待机电流敏感的便携设备或低功耗系统。
最大耗散功率为365mW,结合SOD-123封装的散热能力,支持中等功率稳压应用(最大工作电流约13.5mA,计算:365mW÷27V≈13.5mA),满足多数日常电路的功率需求。
动态阻抗为40Ω,反映稳压值随工作电流变化的程度:阻抗越小,稳压值越稳定。40Ω的阻抗值属于同类器件中等偏优水平,可有效抑制负载电流波动对输出电压的影响,适合传感器基准、ADC参考电压等对电压波动敏感的电路。
PDZ27BGWJ采用SOD-123表面贴装封装,具有以下核心优势:
结合参数特性,PDZ27BGWJ的核心应用场景包括:
Nexperia(安世半导体)是全球领先的分立器件制造商,原飞利浦半导体分立器件业务线,在稳压二极管领域拥有超过50年技术积累。PDZ27BGWJ系列器件具有:
综上,PDZ27BGWJ以精准稳压、低功耗、小尺寸为核心优势,适配中高压稳压、低功耗保护等多类场景,是工业控制、消费电子、通信设备等领域的可靠选型。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
