ZMM12 稳压二极管 产品概述
一、产品简介
ZMM12 是 Hottech(合科泰) 出品的独立式稳压（齐纳）二极管，封装为 LL-34 轴向玻封封装，设计用于在小功率电路中提供稳定的参考电压或浪涌保护。标称稳压值 12V，适合对体积和成本敏感的通用稳压、基准与钳位场景。
二、主要参数
- 稳压值（标称）：12V
- 稳压值范围：11.4V ～ 12.7V
- 反向电流 Ir：100nA（说明书给出测试点为 [email protected]）
- 耗散功率 Pd：500mW（总耗散，环境与散热受限时需注意）
- 动态阻抗 Zzt：20Ω
- 封装：LL-34（轴向玻封，便于穿孔安装）
- 器件类型：独立式稳压二极管（离散元件）
三、产品特点
- 小型轴向封装，便于穿孔安装与手工焊接
- 低漏电流，适用于高阻抗参照与精密电路（在给定测试条件下 Ir≈100nA）
- 中等动态阻抗（Zzt≈20Ω），在稳压电流范围内能提供良好稳压性能
- 500mW 耐功耗，适合小信号和局部稳压应用
四、典型应用
- 基准电压源与比较器参考
- 电源钳位与浪涌保护（限于低功率场合）
- 仪表与传感前端的电压保护
- 家电与消费电子的小功率稳压电路
五、电路与使用建议
- 为保证器件不超过 Pd，计算并限制通过的电流：Iz_max ≈ Pd / Vz（实际需考虑环境温度与散热条件）
- 动态阻抗会影响稳压精度，若需更高精度应配合误差放大或选择更低阻抗型号
- 若用于参考，应在稳压电流附近工作，并加入旁路电容以抑制噪声与瞬态响应
六、封装与安装
LL-34 轴向玻封，耐焊接温度良好，建议采用适度的焊接时间与温度以免热应力损伤。穿孔安装时注意引脚弯折不要过度施力以免封装应力集中。
七、注意事项与可靠性
- 最高耗散受焊盘、环境温度影响，需评估实际散热条件
- 测试条件（如 Ir 在 9.1V 测得 100nA）可能与电路实际工作点不同，设计时请留裕量
- 长期在高温或接近最大 Pd 下工作会降低寿命，建议留有安全裕量

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
