DB3W是一种高可靠性的触发二极管,具有触发电流低、响应速度快等特点,非常适合在各种电子电路中作为保护元件或触发元件使用。其主要工作电压范围为28V至36V,额定工作电压为32V,最大反向电流为50µA,能够在很多不同的应用场景中表现出色。
低触发电流: DB3W的触发电流仅为50µA,使其能够在低功耗电路中有效工作,为系统节省能耗。
紧凑的封装: SOD-123F封装拥有小巧的尺寸,适合高密度的电路设计,能够有效降低空间占用,提高设计灵活性。
高工作电流: 提供高达2A的工作电流,使其在各种负载情况下均能保证稳定性能。
宽工作电压范围: 28V~36V的范围使得DB3W能够适应不同的电压环境,具有更广泛的适用性。
DB3W触发二极管的应用场景包括但不限于以下几个方面:
保护电路: DB3W被广泛用于电源保护电路,能够有效滤除过压及瞬态电流,以保护下游元件不受损害。
开关电源: 在开关电源中,DB3W可以作为反向电压保护二极管,以防止逆电流干扰和设备故障。
自动化控制: 在各种自动化控制系统中,DB3W的快速响应能力使其能够用于信号触发和控制,以保证系统实时、准确的反应。
家用电器: 由于其优越的性能,DB3W也适用于家用电器中的过压保护和电源管理,有助于提高设备的可靠性。
DB3W触发二极管的工作原理基于其电流-电压特性。在正常工作状态下,二极管处于反向偏置状态,当达到一定的触发电压时,二极管迅速转变为导通状态,允许电流通过,完成信号的传递或保护。这种快速切换的特性是其在电子应用中的重要优势。
在使用DB3W触发二极管时,用户需要注意以下几点:
最大功率限制: 确保在设计电路时,DB3W的功率和电流均处于其额定范围内,以避免过载和元件损坏。
散热设计: 尽管DB3W的功耗较低,但在高负载情况下,仍需考虑其散热设计,确保在高温环境下稳定工作。
安装方向: 在实际应用中,确认二极管的安装方向,避免因安装错误导致的电路故障。
环境适应性: 在潮湿或温度变化较大的环境中使用时,需考虑相关的防护措施,以延长产品使用寿命。
DB3W触发二极管凭借其优秀的电气特性和灵活的应用场景,成为市场上备受关注的电子元器件之一。适合各种中低电压场合的应用,尤其在对能效和空间有较高要求的场景中,其优越的性能使其成为设计者的优选。同时,基于其高品质的保证和可靠的工作特性,DB3W将为您的电子项目提供稳定的支持。无论是在家电、工业控制,还是现代电子设备中,DB3W都将展现出其卓越的性能。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
