BZT52C24S是MDD品牌推出的独立式表面贴装稳压二极管,属于小型化稳压器件范畴。其核心设计围绕「24V标称稳压值」展开,适配对空间紧凑、功耗控制有要求的电子电路,可作为电压基准源或过压保护元件使用,广泛覆盖消费电子、工业控制、IoT终端等领域的小型化应用场景。
该器件的电参数围绕稳压性能与功耗控制做了针对性设计,核心参数的实际意义需结合应用场景理解:
标称稳压值为24V,实际生产偏差控制在22.8V~25.6V之间(偏差率约±5%)。这一范围既满足批量生产的一致性要求,又为电路设计预留了合理容差——若系统对稳压精度要求不苛刻(如辅助电源、简单电压钳位),该范围完全适配;若需更高精度,可通过串联微调电阻优化。
测试条件为「反向电压19V(低于标称稳压值)」时,反向漏电流仅100nA。这一参数体现了器件的反向截止特性:未达到稳压击穿电压时,漏电流极小,可有效降低待机功耗,尤其适合电池供电的便携设备等低功耗场景。
最大连续耗散功率为200mW,是器件允许的功率上限。计算实际使用功率时,需结合通过电流与稳压值((P=V×I)),避免长时间工作在功率极限附近——若电路过流风险较高,需串联限流电阻或搭配散热措施。
稳压区动态阻抗为60Ω。动态阻抗反映稳压值随电流变化的灵敏度:阻抗越小,稳压值越稳定。60Ω属于常规稳压二极管的中等水平,可满足大部分非高精度稳压需求(如MCU供电基准、传感器偏置电压)。
BZT52C24S采用SOD-323封装,这是一种超小型表面贴装封装(典型尺寸约1.6mm×0.8mm×0.6mm),具有以下优势:
MDD作为专注于分立器件的品牌,该型号在生产中遵循通用稳压二极管的质量标准:
结合参数特点,BZT52C24S的核心应用集中在小型化、低功耗、非高精度稳压场景:
综上,BZT52C24S是一款性价比突出的小型化稳压二极管,适合对空间、成本敏感但需基础稳压/保护功能的电子设计。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
