BZT52C9V1（BORN 伯恩）——9.1V 稳压二极管产品概述
一、产品简介
BZT52C9V1 是 BORN（伯恩半导体）出品的一款小功率稳压二极管，标称稳压值 9.1V，实际稳压范围为 8.5V～9.6V，封装为 SOD-123。器件设计用于作低功耗稳压、基准电压和浪涌/钳位保护，适合空间受限的表面贴装应用。
二、主要电气参数
- 标称稳压：9.1V（范围 8.5V～9.6V）
- 最大耗散功率 Pd：500mW（在规定散热条件下）
- 反向漏电流 Ir：500nA @ 6V（低电压下漏流小）
- 动态阻抗：Zzk = 100Ω（低电流区/拐点阻抗），Zzt = 15Ω（测试电流下的动态阻抗）
以上参数体现出该器件在较高稳压电流时具有较好的电压稳定性，而在接近击穿拐点的低电流区动态阻抗较大，调节性能下降。
三、使用与计算注意
作为并联（分流）稳压器，常用串联限流电阻配合使用。基本计算：
- 串联电阻 R = (Vin − Vz) / (Iz + Iload)
- 二极管耗散 Pd = Vz × Iz 例如：Vin = 12V，Vz = 9.1V，取 Iz = 5mA，Iload = 10mA，则 R ≈ 193Ω；此时二极管耗散约 0.0455W，远低于额定 0.5W。理论最大稳压电流 Iz_max ≈ Pd/Vz ≈ 0.5W/9.1V ≈ 55mA，但长期工作应按热稳态与可靠性做降额处理（建议连续工作电流明显低于理论极限）。
四、封装与热管理
SOD-123 为小型贴片封装，适合高密度 PCB 布局。由于额定功率仅 500mW，热量主要通过端点和 PCB 散出，实务中应：
- 在焊盘下和周围使用较大铜箔或散热地平面；
- 必要时增加过孔或铜柱导热到内层/底层；
- 考虑在高环境温度或大输入差时对耗散进行降额设计。
五、典型应用场景
- 精简型 9V 参考/稳压源（小电流场合）；
- 输入电压钳位与浪涌保护；
- 信号电平移位与偏置电路；
- 仪表/传感器的低功耗基准。
六、选型与注意事项
- 若需高精度或低噪声基准，请选用专用参考源或更高功率/低阻抗的齐纳管；
- 关注应用中的最大输入电压差与实际工作电流，避免超过 Pd 导致过热；
- 贴装时注意极性（通常有阴极标记），并采取常规防静电措施。
总结：BZT52C9V1（BORN，SOD-123）是一款面向低功耗、小尺寸场合的 9.1V 稳压二极管，适合用于简单的并联稳压、钳位保护与偏置电路。在设计时应重视热管理与工作电流降额，以确保长期可靠运行。

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.
