ESDBT4V5D3 是 CJ(江苏长电/长晶)推出的双向静电放电(ESD)保护器件,采用紧凑的 SOD-323 封装,专为需要高抗冲击能力和低漏电的电子接口设计。该器件针对工业标准的静电冲击和浪涌保护要求进行了优化,具有快速响应、低漏电、可靠的钳位性能,适用于各种消费电子、通信和工业控制接口保护场合。
ESDBT4V5D3 主要用于对敏感电子器件和接口进行瞬态过压、静电放电和浪涌保护。典型应用包括:
由于器件的结电容为 150 pF,适合于电源线或低速信号线保护;若用于高速差分信号(如 USB 2.0/USB3.0、LVDS 等),需评估电容对信号完整性的影响。
设计时应注意:
当系统需要在 ± 极性瞬态、较高脉冲能量环境中进行可靠保护,并且对器件尺寸、漏电有较高要求时,ESDBT4V5D3 是合适的选择。适合保护 5 V 级别的电源线与低速信号线。选型时需重点确认:
如需样片或批量采购信息,可联系 CJ(江苏长电/长晶)授权分销商或代理获取详细数据手册(包括绝对最大额定值、典型波形、封装尺寸和焊接说明)。

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.
