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:
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。
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:
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。
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:
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。
除上述场景外,还可用于:
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。

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.
