MMSZ5256B_R1_00301 为 PANJIT(强茂)出品的一颗独立式稳压二极管,标称稳压值为 30V,采用平面芯片结构并封装于 SOD-123 表面贴装封装。器件针对自动化组装工艺优化,适用于中低功率电压参考、浪涌限压与过压保护等场合。
器件采用平面芯片结构,封装为 SOD-123 小型表贴封装,体积小、重量轻,适合集成于空间受限的电路板上。SOD-123 支持高速贴片与回流焊流程,利于大批量自动化生产与组装。
500mW 的耗散功率要求在实际电路中注意热管理与功率降额。在常温环境下可直接作为 30V 级别的稳压或保护元件,但在高结温条件下漏电流与稳压特性会发生变化,需根据实际 PCB 散热条件或增加铜箔面积进行降额。稳态阻抗 Zzt(49Ω)与膝部阻抗 Zzk(600Ω)表明该器件在低电流区间的调节能力有限,更适合用于参考或保护,而非高精度基准源。
该产品符合欧盟 RoHS 2.0 的无铅要求,采用符合 IEC 61249 标准的绿色模塑料材料,满足环保与可追溯性要求。平面芯片结构与 SOD-123 封装在焊接可靠性与温度循环测试方面具有良好表现,适合一般工业与商用电子设备。
如需在中等精度下实现 30V 级别的稳压或作为保护二极管,MMSZ5256B_R1_00301 提供了小体积、易组装与环保合规的方案。若应用对电压稳定度、温漂或低频噪声有更高要求,建议在器件选型时参考更高档次的精密基准或配合运算放大器组成更复杂的稳压方案。安装时遵循厂商的回流焊曲线与静电防护规范,以确保器件性能与寿命。

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.
