PESD12V0L1BA 瞬态抑制二极管产品概述

一、产品定位与核心功能

PESD12V0L1BA是雷卯电子(Leiditech)推出的一款小型化瞬态抑制二极管(TVS),专注于电子电路的静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌干扰防护,特别适配12V及以下低电压电路的过压保护需求,兼顾「小封装高密度」与「高防护性能」两大核心优势。

二、关键防护参数解析

1. 截止与击穿特性

  • 反向截止电压(Vrwm):12V
    器件在电路正常工作时(反向电压≤12V)处于截止状态,无明显导通电流,不干扰信号传输或电源功耗;
  • 典型击穿电压(Vbr):16.2V
    反向过压达到此阈值时,器件快速击穿导通,为过压防护提供明确的触发起点,避免防护延迟。

2. 浪涌承受能力

  • 峰值脉冲功率(Ppp):360W(@8/20μs浪涌波形)
    可有效吸收常见浪涌干扰能量(如电源端口瞬态浪涌、接口插拔冲击),保护后端敏感器件(MCU、传感器等)免受过压损坏。

3. 钳位电压控制

  • 钳位电压:24V
    过压时快速将电路电压钳位至24V以内,远低于多数敏感元器件的最大耐压(如MCU耐压≤3.3V/5V),从根源避免器件击穿。

三、电气特性与信号完整性

1. 低漏电流设计

  • 反向电流(Ir):100nA(@Vr=12V)
    漏电流极小,不会对电路正常信号传输造成干扰,也能满足便携式设备的低功耗需求(如智能手环、蓝牙耳机)。

2. 结电容适配性

  • 结电容(Cj):45pF
    虽非GHz级射频电路的最优选择,但能满足中低速数字接口(I2C、SPI、USB 2.0)及模拟信号电路的信号完整性要求,避免信号失真。

四、封装与物理特性

采用SOD-323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:

  • 适合高密度PCB设计(如小型传感器模块、IoT节点);
  • 兼容回流焊、波峰焊等常规焊接工艺,生产兼容性好;
  • 耐温范围宽(-55℃~150℃),适应工业级与消费级设备的环境要求。

五、符合标准与防护等级

产品严格遵循国际EMC标准,覆盖电子设备常见干扰场景:

  • IEC 61000-4-2(ESD):满足接触放电±8kV、空气放电±15kV的典型防护要求;
  • IEC 61000-4-4(EFT):可承受4kV/5kHz的电快速瞬变脉冲群冲击;
  • IEC 61000-4-5(浪涌):兼容2kV/1.2/50μs的浪涌波形防护。

六、典型应用场景

  1. 便携式电子设备:手机、平板、智能手环的USB接口、耳机接口、充电端口防护;
  2. 物联网(IoT)节点:温湿度传感器、无线模块的信号/电源端口防护;
  3. 低速数字接口:I2C、SPI、UART等通信接口的过压保护;
  4. 小型电源电路:5V/12V直流电源端口的浪涌与ESD防护。

七、产品选型优势

  1. 小封装与高防护平衡:SOD-323封装下实现360W浪涌承受能力,无需牺牲空间换防护;
  2. 低功耗适配:100nA漏电流满足便携式设备的续航需求;
  3. 国产可靠品牌:雷卯电子的EMC器件经过市场验证,性价比优于部分进口同类产品;
  4. 多场景覆盖:单器件同时应对ESD、EFT、浪涌,减少电路防护方案的器件数量。

该产品通过「性能稳定、成本可控、空间紧凑」的特点,成为低电压电路防护的高性价比选择。

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
