ESDS302DBVR 是 TI(德州仪器)推出的一款双路、双向瞬态电压抑制(TVS/ESD)二极管,封装为 SOT-23-5。该器件专为对接口信号线提供静电放电(ESD)和浪涌保护而设计,具有低结电容、低漏电和高脉冲吸收能力,适合保护低压高速数据接口与通用 I/O 端口。
这些参数决定了 ESDS302DBVR 在对 3.3V 及以下电平信号线进行快速瞬态抑制时具有良好的性能:低结电容有助于维持信号完整性,低漏电利于低功耗设计,高脉冲功率与较大的峰值脉冲电流保证了对短时高能量瞬态的吸收能力。
注意:由于 Vrwm=3.6 V,该器件更适用于 3.3 V 及以下接口;用于 5 V 总线时需评估漏电与夹断行为,或选择 Vrwm 更高的型号。
总结:ESDS302DBVR 以其双路、双向、低电容和高脉冲吸收能力,适合对 3.3 V 及以下高速数据线进行紧凑型的静电与瞬态浪涌保护。正确的 PCB 布局与对工作电压的匹配是发挥其性能的关键。有关引脚、典型波形和完整特性曲线,请参阅 TI 官方数据手册。

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.
