ZMM15（Hottech 合科泰）产品概述
一、产品简介
ZMM15 是 Hottech（合科泰）出品的一款独立式稳压二极管，标称稳压值集中在 13.8V~15.6V 区间（典型为 15V 级别），采用 LL-34 玻封轴向封装，适用于小功率稳压、基准和浪涌钳位场合。器件设计针对精度与低漏电要求，适合在有限功率预算下工作。
二、主要参数
- 稳压范围：13.8V ~ 15.6V（Zener 级别 15V）
- 最大耗散功率 Pd：500 mW（自由空气条件下）
- 反向漏电 Ir：100 nA（标称数据中出现 100 nA@1V，与描述处 100 nA@11V 有出入，采购与设计时请以厂家正式数据表为准）
- 动态阻抗：Zzt = 30 Ω（测试电流区域），Zzk = 110 Ω（击穿/低电流区）
- 封装：LL-34（轴向玻封，适用于通孔安装）
三、特性与优势
- 低漏电：100 nA 级别的漏电利于高阻电路与精密基准应用。
- 中等稳压精度：稳压范围紧凑，可用于 12V~16V 范围内的稳压与保护场合。
- 小体积、通孔封装：LL-34 封装方便插装与手工焊接，适合小批量或维修场景。
- 良好的动态阻抗特性：30 Ω 的 Zzt 在常用测试电流下能提供较稳定的稳压性能，而较高的 Zzk 提示在低电流时电压变化增大，设计时需考虑工作电流点。
四、典型应用
- 小功率稳压源与基准电路（作为并联基准或参考电压）
- 输入过压钳位与浪涌保护（与限流元件配合）
- 电池充放电控制与监测电路
- 仪表、传感器前端的稳压/保护元件
五、电路与热管理注意事项
- 串联限流：在用作并联稳压时须加串联电阻 Rs，Iz = (Vin - Vz)/Rs；保证 Vz * Iz ≤ Pd（Iz_max = Pd/Vz）。
- 功耗计算：稳压二极管自身耗散为 Vz × Iz，输入侧限流器也会产生功耗，整体热预算必须计算到位。
- 温度影响：环境温度升高会降低额定耗散能力，必要时做功率降额或增加散热。
- 启动与浪涌：避免超过瞬间最大脉冲能量，必要时配合限流元件或TVS设备。
六、封装与可靠性
LL-34 玻封轴向封装具备良好的电气绝缘与机械强度，适合通孔焊接与长期可靠性要求较高的应用。出厂前应参考湿度和焊接温度曲线，避免过热损伤器件。
七、选型与资料建议
在最终选型前建议索取并核对厂家完整数据表，确认漏电在实际工作电压/温度下的取值、测试电流点、最大反向电压和瞬态允许值。如需提高功率余量或降低动态阻抗，可考虑选用功率更高或专用参考源替代。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
