MMSZ5257B_R1_00001是强茂(PANJIT) 推出的一款独立式稳压二极管,采用SOD-123小型表面贴装封装,专为需要稳定33V左右电压的电子电路设计,兼具低功耗、宽温适应性与紧凑尺寸等特点,适用于多种工业及消费电子场景。
该器件属于通用型稳压二极管,核心功能是在反向击穿状态下提供稳定的电压输出,满足电路对基准电压或过压保护的需求。作为独立式配置,无需额外并联元件即可实现稳压功能,简化电路设计;SOD-123封装则契合现代电子设备小型化、高密度布局的趋势,可直接焊接于PCB表面,安装便捷。
反向漏电流(Ir)为100nA@25V(反向电压25V时),该数值极低,说明器件在反向未击穿状态下的功耗极小,适合低功耗电路设计,可有效降低待机状态下的能量损耗。
最大耗散功率(Pd)为500mW(0.5W),是器件允许的最大功耗上限。实际应用中需注意:工作时的功耗(稳压值×工作电流)需低于此值,避免过热损坏。例如,若稳压值为33V,最大允许工作电流约为15mA(500mW÷33V≈15mA)。
动态阻抗是衡量稳压性能的核心指标,包含两个关键参数:
结温范围为**-55℃~+150℃**,覆盖了极宽的温度区间,可适应户外低温环境(如-55℃)及高负载下的高温环境(如150℃),满足工业控制、汽车电子等恶劣工况的可靠性需求。
SOD-123是小型表面贴装无引线封装,尺寸通常为2.4mm×1.6mm×1.0mm,具有以下特点:
该器件的参数特性使其适用于以下场景:
强茂(PANJIT)作为全球知名半导体制造商,其产品符合RoHS、REACH等环保标准,且经过严格的可靠性测试(如温度循环、湿度测试等),确保MMSZ5257B_R1_00001在长期工作中的稳定性。此外,该器件的低漏电流、宽温范围等特性,进一步提升了其在恶劣环境下的使用寿命。
综上,MMSZ5257B_R1_00001稳压二极管凭借紧凑尺寸、宽温适应性、低功耗等优势,成为通用稳压电路的理想选择,可广泛应用于消费电子、工业控制、汽车电子等领域。
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.
