ESD762DBZR 是 TI(德州仪器)推出的一款双路双向瞬态抑制二极管,专为高可靠性静电和浪涌防护而设计。主要参数包括:反向截止电压 Vrwm = ±24 V、钳位电压约 36 V、峰值脉冲电流 Ipp = 2.5 A(8/20 μs)、峰值脉冲功率 Ppp = 90 W(8/20 μs)、结电容 Cj = 1.7 pF,反向漏电流 Ir ≈ 50 nA,工作温度范围 -55 ℃ ~ +150 ℃,满足 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)规范。器件采用 SOT-23(DBZ)小封装,适合空间受限的电路板设计。
该器件为双通道、双向保护结构,能够在信号线正负极出现瞬态高电压时快速钳制,吸收能量并将过电压限制在安全范围,保护下游敏感器件不被破坏。8/20 μs 浪涌参数表示在工业浪涌测试条件下器件的承受能力,±20 kV 表示对接触/空气放电类高能 ESD 的强化保护能力。
ESD762DBZR 提供了在体积受限场合下兼顾低电容与高能量吸收能力的解决方案,是保护双路高速/工业接口的可靠选择。

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.
