PJGBLC03C 过压保护器件产品概述

一、产品核心定位与典型应用场景

PJGBLC03C是雷卯电子(Leiditech)推出的双向瞬态抑制二极管(TVS),专为3.3V低压系统设计,核心作用是在静电放电(ESD)、雷击浪涌或电源瞬变时,快速钳位电压至安全范围,避免后端敏感器件(如MCU、传感器、通信接口)损坏。

其典型应用覆盖三大领域:

  1. 消费电子终端:手机/平板充电接口、蓝牙耳机充电仓、智能手表无线充电触点、TWS耳机充电盒接口;
  2. 物联网低功耗设备:温湿度/光照传感器节点、低功耗蓝牙(BLE)模块、环境监测终端;
  3. 工业/通信接口:PLC数字IO口、串口(UART)、I2C/SPI总线、小型路由器LAN/WAN接口。

这些场景的共性需求是:工作电压3.3V、信号速率较高(需低电容)、符合IEC 61000-4-5浪涌防护标准。

二、关键电气参数深度解析

PJGBLC03C的参数精准匹配3.3V系统防护需求,核心参数的实际意义如下:

1. 双向极性与防护逻辑

双向设计意味着正反方向均可导通防护,适合串口TX/RX、I2C SDA/SCL等双向传输接口,无需区分引脚方向,简化PCB布局。

2. 正常工作与导通阈值

  • 反向截止电压(Vrwm)3.3V:电路正常工作时(电压≤3.3V),器件截止,漏电流极小,不影响低功耗设备待机;
  • 击穿电压4V:电压超过3.3V时(如瞬变电压),器件快速导通,确保后端器件损坏前启动防护。

3. 浪涌承受与钳位能力

  • 峰值脉冲功率400W@8/20μs:可承受标准8/20μs浪涌波形(模拟雷击/电源瞬变),满足消费电子/物联网设备的浪涌防护等级;
  • 钳位电压20V:浪涌峰值时钳位电压≤20V,与多数3.3V MCU的IO口最大耐压(15-20V)匹配,避免过压击穿。

4. 信号完整性与低功耗

  • 结电容Cj=0.6pF:远低于普通TVS管(1-5pF),兼容100Mbps以上高速信号(如SPI 50MHz、I2C 400kHz),无信号反射/延迟;
  • 反向电流Ir=200nA:正常工作漏电流仅200nA,对电池供电设备(待机电流μA级)影响可忽略,满足低功耗设计。

三、封装与可靠性设计

PJGBLC03C采用SOD-323封装,尺寸为2.0mm×1.25mm×1.0mm,属于小型表面贴装封装,适合高密度PCB(如TWS充电仓紧凑空间)。

可靠性方面:

  • 通过IEC 61000-4-5浪涌抗扰度测试(1.2/50μs电压波、8/20μs电流波),可承受典型浪涌等级(2kV接触放电、1kV空气放电);
  • 工作温度范围覆盖-55℃~125℃,满足消费电子与工业级环境适应性。

四、品牌与合规性

雷卯电子是国内专注防护器件的厂商,产品覆盖TVS、ESD、压敏电阻等系列,广泛应用于多领域。

PJGBLC03C符合RoHS环保标准(无铅无镉),批量生产击穿电压偏差≤±5%,参数一致性好,适合大规模量产。

五、补充适用场景

除上述场景外,还可用于:

  • 智能家居传感器接口(智能门锁指纹模块、智能灯光感模块);
  • 小型医疗设备低电压接口(血糖监测仪充电口);
  • 无人机通信模块接口(遥控接收串口)。

其双向防护、低电容、小封装的特点,使其成为3.3V系统“性能与成本平衡”的首选防护器件之一。

WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
