1N5248B_AY_10001 产品概述
一、产品简介
1N5248B_AY_10001 是强茂（PANJIT）出品的一款单只独立式 18V 稳压二极管，采用平面芯片结构和 DO-35 轴向封装，面向需要稳定参考电压、低电流稳压及浪涌钳位的电子电路。器件为无铅产品，符合欧盟 RoHS 2.0 标准，适配自动化组装流程。
二、主要电气参数
- 标称稳压值（Vz）：18V
- 稳压值允许范围：17.1V ~ 18.9V
- 反向电流（Ir）：100 nA @ 14V
- 耗散功率（Pd）：500 mW（器件总耗散能力）
- 稳态阻抗（Zzt）：21 Ω
- 冲击/小信号阻抗（Zzk）：600 Ω
三、结构与封装特性
- 芯片工艺：平面芯片，结构稳定、特性一致性好，有利于批量生产与自动化装配。
- 封装形式：DO-35（轴向引线），适用于通孔安装，易于手工焊接和波峰/选择性焊接工艺。
- 热管理：500 mW 的功耗级别适合中低功率参考或保护用途，但在高环境温度或连续高负载下需注意热量管理与降额使用。
四、典型应用场景
- 精密低功耗电源参考与基准电压源。
- 模拟信号处理与放大电路的偏置/温漂补偿。
- 输入浪涌/瞬态电压钳位及保护电路。
- 仪表、传感器与便携设备中的稳压单元。
五、选型与使用建议
- 为保证长期可靠性，工作时建议留有功率余量（实际耗散尽量低于额定 Pd），并考虑散热路径与环境温度的影响。
- 根据电路工作电流选择匹配的稳压管；Zzt（21 Ω）表明在测试电流下有较低的动态阻抗，适合对纹波抑制有一定要求的场合；Zzk 值指示在小电流或瞬态条件下的高阻抗特性。
- 在高精度应用中，应结合实际电流与温度特性进行实验验证，确认稳压点和温度系数是否满足系统要求。
六、存储与焊接注意事项
- 避免强烈机械应力，存储环境保持干燥、防尘；长期存放建议原包装密封保存。
- 封装为通孔轴向件，适用手工焊接或波峰焊，焊接时避免在封装体上直接加热过长时间，以防内部应力或封装损伤；详细焊接温度/时间请参照厂方工艺说明书。
- 处理和装配过程中注意静电防护与导通极性识别，避免反向错误连接造成器件损坏。

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.
