BZX84C33HE3-TP 是美微科(MCC)出品的一款低功耗独立式稳压二极管,封装为 SOT-23,额定耗散功率为 350mW。标称稳压值为 33V,允许公差 ±5%,因此实际稳压值范围为约 31V 至 35V。该器件适合用作高电压、小电流场合的基准或过压保护元件。
器件采用常见的 SOT-23 三引脚封装(实际只需两引脚使用,一个为焊盘或情形保留)。封装利于自动贴装和批量生产,但热阻较大,建议在 PCB 设计时为其提供适当的铜箔散热路径。
总结:BZX84C33HE3-TP 以其 33V 的中高稳压值、低漏电及小体积封装,适合用于空间受限、需低电流高电压稳压或保护的场合。在设计时应重视耗散功率限制、热管理与工作电流范围,配合合适的限流与 PCB 布局可发挥稳定可靠的性能。

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.
