1N4753A-G_AY_100A3 产品概述
一、产品简介
1N4753A-G_AY_100A3 是强茂（PANJIT）出品的独立式稳压二极管，标称稳压值为 36V，精度 ±5%，典型封装为 DO-41G 轴向封装。该器件适用于低功率稳压、基准源和浪涌/过压钳位等场合，具有玻璃钝化的可靠封装和宽温度工作范围。
二、电气与热特性
- 标称稳压值（Vz）：36V（允许范围 34.2V ～ 37.8V，±5%）
- 额定耗散功率（Pd）：1W（在规定散热条件下）
- 反向漏电流（Ir）：100 nA @ 27.4V（漏电随温度升高而增加）
- 动态阻抗：Zzt ≈ 50Ω（测试电流下），Zzk ≈ 1kΩ（低电流条件下）
- 结温范围：-65℃ ～ +200℃（器件级极限，使用时需保证结温低于允许值）
三、典型应用场景
- 稳压参考与基准源：为模拟电路或比较器提供中低精度的电压基准。
- 过压保护/钳位：在信号线或电源线上对短时过压进行限制。
- 低功耗电源设计：在电流受限的系统中作为简单稳压元件使用。
- 测试和校准电路：用于提供稳定且可重复的电压节点。
四、设计与使用建议
- 串联限流：为防止超出 Pd，须通过串联电阻或限流电路控制流经稳压管的电流。最大稳压电流约为 Iz_max = Pd / Vz ≈ 1W / 36V ≈ 27.8 mA。
- 散热管理：DO-41G 为轴向引线封装，散热主要经引线和周围空气。在高环境温度或持续大电流条件下，应对功率进行降额处理，避免结温升高。
- 漏电与偏差：低电流工况下稳压值和阻抗会有较大波动，设计时考虑动态阻抗和温漂影响。
- 极性与安装：注意极性（标称为稳压二极管的反向工作模式），轴向封装便于插装或波峰/手工焊接，焊接时避免过热损伤封装。
五、示例计算
若输入电压为 48V，欲用本稳压二极管得到约 36V 输出，串联电阻 R = (Vin - Vz) / Iz。为保证在最坏工况下不超过耗散功率，取 Iz ≤ 20 mA（安全余量），则 R ≥ (48-36)/0.02 = 600 Ω，耗散功率在稳压管端约 P = Vz * Iz = 36 * 0.02 = 0.72 W，低于 1W 但需注意环境温度影响。
总体而言，1N4753A-G_AY_100A3 以其 36V 稳压点、1W 功率等级和可靠封装适用于多种中小功率稳压与钳位场合。设计时应重视限流和散热，确保长期可靠运行。

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.
