BZV85‑C8V2,133 产品概述
一、产品简介
BZV85‑C8V2,133 是 Nexperia（安世）生产的一款 DO‑41 封装的稳压二极管，标称稳压值为 8.2V。该器件在反向工作区通过雪崩/齐纳机制提供稳定电压，适用于低功耗电压参考、基准偏置与纹波钳位等场合。
二、主要电气参数
- 标称稳压值（Vz）：8.2V
- 反向漏电流（Ir）：700 nA @ 5V（典型值，随温度升高会增加）
- 耗散功率（Pd）：1.3 W（器件总耗散上限，受环境温升约束）
- 动态阻抗（Zzt）：5 Ω（表征小信号下稳压性能）
- 封装：DO‑41（通过孔，便于波峰/选择性焊接）
三、使用与热管理要点
在 8.2V 稳压点下，理论最大稳态电流可由 Pd/Vz 估算≈158 mA，但该值为热限计算值，实际应用中应留有裕量，建议工作电流远低于此以保证长期可靠性。DO‑41 的散热主要通过引脚和焊盘传导，设计 PCB 时应考虑适当的铜箔来提升散热能力，并避免长时间在高环境温度下工作以控制反向漏流与稳压漂移。
四、典型应用场景
- 小功率稳压/基准电压源（与限流电阻配合）
- 过压/浪涌钳位与保护元件
- 偏置电路与信号线参考电压
- 消费电子、通信终端、仪表等需要稳定 8.2V 基准的场合
五、设计注意事项
使用本类稳压二极管时，应注意反向工作条件（勿正向作为整流长期承载），选择串联限流电阻以限制通过器件的电流，并根据环境温度和封装散热条件重新评估最大允许电流。动态阻抗为 5 Ω，表示在有较大负载变化时会有相应的电压摆幅，若需要更精确的基准应考虑精密参考源或并联低阻抗缓冲。
BZV85‑C8V2,133 以其紧凑的 DO‑41 封装、适中的稳压值与低漏电特性，适合于各种通用级别的稳压与保护应用。

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.
