BZX84C22 为独立式(单只)22V 稳压二极管,由江苏长电/长晶(CJ)生产,采用 SOT-23 小型表面贴装封装。标称稳压值为 22V,规定范围为 20.8V~23.3V,具有低反向泄漏、适合低至中等功率的基准稳压与抑制用途。该器件适用于空间受限的电路板设计,可作为精简型稳压/钳位与参考元件使用。
BZX84C22 采用 SOT-23 表面贴装封装,体积小,便于自动贴片与高速回流焊工艺。SOT-23 的热阻较大,单只元件在满额定功耗时结温上升明显,因此在 PCB 布局时应配合较大的散热铜箔或热电路径来降低结温。CJ(江苏长电/长晶)品牌具有良好的产能与品质控制,适合批量采购与量产使用。
常见用法为串联限流电阻 + 稳压二极管的齐纳/稳压器结构:
总结:BZX84C22(CJ,SOT-23)是面向小体积、低至中等功耗场合的 22V 稳压二极管,适合作为电压钳位、基准或简单的分流稳压元件。在电路设计中需关注最大耗散、动态阻抗与热管理,合理选取工作电流以保证长期可靠性。如需更详细的性能曲线或规范测试条件,请参阅 CJ 官方数据表。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
