PZ1D15VH 稳压二极管(齐纳)产品概述

一、产品简介

PZ1D15VH 是 Prisemi(芯导)推出的一款低功耗稳压二极管(齐纳二极管),为独立式配置,采用 SOD-123 小封装。该器件以稳压参考与过压保护为主要用途,适用于空间受限、功耗较低的稳压与基准场合,广泛用于消费类电子、仪表和通信终端等电路中。

二、主要技术参数

  • 标称稳压值(Vz):15 V
  • 稳压范围:13.8 V ~ 15.6 V
  • 反向漏电流(Ir):100 nA(典型/最大值,具体测量条件见厂商资料)
  • 耗散功率(Pd):500 mW
  • 动态阻抗(Zzt):40 Ω(测试条件下)
  • 工作结温范围(Tj):-55 ℃ ~ +150 ℃
  • 封装:SOD-123,独立式器件

三、关键特性

  • 中等电压(15 V)参考:适合需要 12–15 V 量级稳压基准或保护点的电路。
  • 低漏电流:100 nA 级别的反向电流有利于高阻抗回路或精密测量应用。
  • 小体积封装:SOD-123 体积小、适合表贴装配,便于自动化贴装与批量生产。
  • 中等动态阻抗:40 Ω 表明在规定工作电流附近有一定压降变化,适用于不要求极高精度的场合。

四、封装与热管理

SOD-123 为小型表面贴装封装,便于在密集 PCB 布局中使用。由于最大耗散功率仅 500 mW,使用时须注意热设计:应计算通过二极管的最大电流并依据 Pd 限制来选取串联限流电阻与散热布局。实际可导出最大稳态电流 Iz(max) ≈ Pd / Vz ≈ 500 mW / 15 V ≈ 33 mA(仅作估算,应用时应留安全裕量并参考厂方温度依赖曲线)。

五、典型应用场景

  • 低功耗稳压基准与辅助电源稳压(小电流场合)
  • 过压保护与电压夹位(限制输入瞬态至安全电平)
  • 仪表放大电路的参考点与偏置电路
  • 通信设备的局部电压参考与钳位

六、典型电路与使用注意

  • 典型用法为反向并联作为稳压元件,输出电压通过串联电阻 R 限流:R = (Vin - Vz) / Iz,其中 Iz 需保证在稳压工作点且不超过 Iz(max)。
  • 在有纹波或瞬态时,建议在齐纳两端并联去耦电容以降低噪声与改善瞬态响应。
  • 由于动态阻抗较高,若需更高精度的稳压或更大电流,应考虑低阻抗或有源稳压方案。

七、可靠性与温度特性

PZ1D15VH 的结温范围宽(-55 ℃ 至 +150 ℃),适合严苛环境应用。但器件耗散功率会随环境温度上升而受限,应遵循厂方的功率随温度降额曲线以避免过热。长期可靠性与焊接热循环性能建议参考 Prisemi 的详细可靠性说明与测试报告。

八、选型建议与替代

  • 若电路需要更低动态阻抗或更大稳压电流,应选择功率更高或低阻抗型号(例如 1 W 级或专用参考源)。
  • 若对封装或配套自动化装贴有特殊要求,可考虑同厂或其他厂家的 SOD-123 封装齐纳,比较其 Vz 公差、Zzt 与 Ir 等参数以匹配需求。

九、储存与焊接注意事项

  • 建议按一般 SMD 器件的防潮储存与回流焊工艺处理,避免超时烘烤后再回流以减少焊接缺陷。
  • 回流焊温度曲线应符合制造商资料,避免长时间高温导致器件热应力。

十、结语

PZ1D15VH 是一款面向低功耗、空间受限场合的 15 V 齐纳二极管,具有低漏电、封装紧凑的特点。设计时需注意功率与温度约束,并根据动态阻抗与稳压精度要求判断是否满足系统指标。欲获取更详细的电性能曲线、引脚外形图与温度降额资料,请参考 Prisemi 官方数据手册。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
