1N5252BPF 是一款硅平面齐纳二极管,标称稳压值为 24V(允许范围 22.8V ~ 25.2V),精度为 ±5%。该器件采用 DO-35 轴向封装,适合通孔安装与点对点连接,常用于作为简单的基准电压、稳压保护与电路限幅元件。品牌为 ST(先科),器件面向需要中等精度和小功耗稳压/保护的应用场景。
这些参数共同决定了器件在不同工作电流下的稳压能力、噪声和响应特性。Zzt 较低表明在测试电流附近电压稳定性良好;Zzk 较高意味着在极低电流区稳压特性变差,需要避免长期在该区工作。
标称耗散功率 500 mW 为器件在适宜散热条件下的最大允许值。实际使用时应考虑以下几点:
举例:若输入电压为 48V,目标使齐纳电流 Iz ≈ 10 mA,则串联电阻 Rs = (48V − 24V) / 10 mA = 2.4 kΩ,电阻耗散约 0.24 W,齐纳耗散约 0.24 W,均在安全范围内。
1N5252BPF(24V,±5%,Pd=500 mW,DO-35)是一款适用于中等精度基准与保护用途的硅平面齐纳二极管。凭借较低的测试动态阻抗和小漏电流特性,它在小功率分立稳压与过压钳位场合表现良好。合理的限流设计与热管理是其稳定可靠应用的关键。若对精度或温漂有更高要求,应评估替代的精密参考源或选型更高等级齐纳/基准器件。

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.
