SMBJ12A TVS二极管产品概述

概要

SMBJ12A 是一种由晶导微电子生产的静电和浪涌保护(TVS/ESD)二极管,专门设计用于保护电子设备免受静电放电(ESD)和瞬时浪涌电流的损害。以下是对此产品的详细介绍。

基础参数

  • 击穿电压(Vc): 13.3V
    • 这是指在正常工作条件下,TVS二极管开始进行电压钳位的电压值。
  • 反向截止电压(Vrwm): 12V
    • 这是指在反向偏置状态下,TVS二极管可以承受的最大持续电压。
  • 反向漏电流(Ir): 1uA
    • 在反向截止电压下,通过TVS二极管的微小电流。
  • 峰值脉冲功率(Ppp): 600W
    • 表示TVS二极管在短时间内(通常为10/1000μs)可以承受的最大功率。
  • 峰值脉冲电流(Ipp): 30.2A
    • 表示TVS二极管在短时间内可以承受的最大电流。
  • 最大钳位电压: 19.9V
    • 当TVS二极管开始进行电压钳位时,能够限制的最大电压值。

商品分类

  • 静电和浪涌保护(TVS/ESD)
    • 这类设备专门用于保护电子设备免受静电放电和瞬时浪涌电流的影响。

Sourcing availability signal

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
