MMSZ5246B-TP是美微科(MCC) 推出的独立式表面贴装稳压二极管,属于MMSZ系列小功率稳压管产品线。该产品专为小功率直流电路的电压稳定、过压保护及电压基准场景设计,以高性价比、宽温度适应性和小封装优势,适配消费电子、工业控制、汽车电子(辅助级)等领域的轻量化设计需求。
产品核心参数直接决定其应用适配性,以下为关键参数的定义与实际意义:
标称稳压值(Vz):16V
反向击穿电压的典型值,是稳压功能的核心指标——当反向电压达到16V左右时,二极管进入反向击穿区,电压基本保持稳定(受动态阻抗影响极小)。
反向漏电流(Ir):100nA @ 12V
测试条件为反向电压12V(低于稳压值),漏电流仅100nA,说明反向截止状态下漏电极低,可有效减少待机功耗,适合对功耗敏感的便携设备。
动态阻抗(Zzt=17Ω、Zzk=600Ω)
最大耗散功率(Pd):500mW
产品允许的最大功耗,需结合实际工作电流计算(Pd=Vz×Iz),适用于小功率电路(如5mA~30mA电流范围的稳压场景)。
工作结温范围:-65℃~+150℃
覆盖工业级宽温度范围,可在极端环境(如低温户外、高温设备内部)稳定工作,小功率场景下无需额外散热设计。
产品采用SOD-123表面贴装封装,具备以下物理优势:
结合参数特性,MMSZ5246B-TP主要适用于以下场景:
美微科(MCC)作为国内专业半导体器件厂商,MMSZ5246B-TP具备以下可靠性保障:
若需调整或替代,可参考以下要点:
以上概述覆盖了MMSZ5246B-TP的核心特性、参数、应用及选型,可作为电路设计与采购的参考依据。

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.
