PESD3V3L2BT 产品概述

概要

PESD3V3L2BT 是由 TECH PUBLIC (台舟电子) 制造的一款高性能静电和浪涌保护(TVS/ESD)二极管,专门设计用于保护电子设备中的敏感组件免受静电放电(ESD)和瞬时浪涌电流的损害。以下是对此产品的详细介绍。

基本参数

  • 击穿电压: 3.8V(最小值),这表示在此电压下,二极管开始导通并吸收过载能量。
  • 反向截止电压(Vrwm): 3.3V,这是二极管在正常工作状态下可以承受的最大反向电压。
  • 反向漏电流(Ir): 100nA,这表明在正常工作条件下,二极管的漏电流极小,几乎可以忽略。
  • 峰值脉冲功率(Ppp): 200W,这表示二极管可以在短时间内吸收和分散的最大能量。
  • 峰值脉冲电流(Ipp): 22A(10/1000us),这表明二极管可以承受的最大瞬时电流。
  • 最大钳位电压: 10V,这是指当过载发生时,二极管会将电压钳制在此水平以保护下游设备。
  • 极性: 双向(Bidirectional),这意味着该二极管可以保护正向和反向过载。
  • 通道数: 双路,这意味着一个封装内包含两个独立的保护通道。

应用场景

PESD3V3L2BT 主要用于以下应用场景:

  • PCAN/串口保护: 由于其低钳位电压和高峰值脉冲电流能力,非常适合用于保护汽车控制器局域网(CAN)总线和其他串口通信接口。
  • 电子设备静电保护: 对于需要防护静电放电的电子设备,如手机、平板电脑、智能家居设备等,PESD3V3L2BT 提供了可靠的静电保护。
  • 工业控制系统: 在工业控制系统中,PESD3V3L2BT 可以保护敏感电子组件免受电源线路或环境中的瞬时浪涌电流影响。

特性和优势

  1. 高性能静电保护:
    • 符合 IEC 61000-4-2 标准,空气放电 30kA 和接触放电 30kA,确保设备在严酷的静电环境中保持稳定运行。
  2. 低钳位电压:
    • 最大钳位电压为 10V,确保在过载条件下不会对被保护的设备造成额外压力。
  3. 高峰值脉冲电流能力:
    • 可以承受高达 22A 的峰值脉冲电流(10/1000us),适用于需要高能量吸收能力的应用场景。
  4. 双向保护:
    • 双向极性设计,使其能够保护正向和反向过载,提高了保护的全面性。
  5. 小尺寸封装:
    • 采用 SOT-23 封装,体积小巧,适合于空间有限的现代电子产品设计。

工程应用注意事项

  1. 安装位置:
    • 应尽可能靠近需要保护的敏感组件安装,以减少引线长度和提高保护效果。
  2. 电路设计:
    • 在设计时应确保电路布局合理,避免高频信号干扰和电磁兼容性问题。
  3. 选择合适的参数:
    • 根据具体应用场景选择合适的TVS二极管参数,确保其能够满足实际工作条件下的要求。

总结

PESD3V3L2BT 是一款功能强大、性能优异的静电和浪涌保护二极管,广泛应用于各种需要高可靠性和高保护能力的电子设备中。其双向保护、低钳位电压和高峰值脉冲电流能力,使其成为保护敏感电子组件的理想选择。通过合理的设计和安装,可以充分发挥其保护功能,确保设备在各种环境条件下稳定运行。

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
