UMH10N 双数字晶体管 产品概述
一、概述
UMH10N 是江苏长电（CJ/长晶）推出的一款双数字晶体管，采用 SOT-363 超小封装，集成了基极限流电阻和截止电阻，面向数字接口和小功率开关场合。器件结构将两组 NPN 小信号晶体管与配套电阻封装在同一芯片中，简化外部电路，提高 PCB 布局密度，适合便携、消费类电子与工业控制中的通用开关驱动。
二、主要参数
- 集-射极击穿电压 Vceo：50 V
- 集电极电流 Ic（最大）：100 mA
- 功耗 Pd：150 mW
- 直流电流增益 hFE：典型 80（测试条件 10 mA, Vce=5 V）
- 最小导通输入电压 VI(on)：1.1 V
- 最大关断输入电压 VI(off)：0.5 V
- 导通输出电压 VO(on)：约 0.3 V
- 内置基极电阻（典型）：2.86 kΩ，阻值比约 26
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：SOT-363（超小型）
三、特点与优势
- 集成基极限流与截止电阻，免去外部电阻器，设计简单，降低 BOM 成本。
- 低饱和压（VO(on) ≈ 0.3 V）和较高 hFE，在 10 mA 工作点具有良好开关效率，适合驱动 LED、小继电器或小功率负载。
- 小型 SOT-363 封装有利于高密度布板和体积受限应用。
- 宽温度范围及良好可靠性，适应工业级环境要求。
四、典型应用
- MCU/逻辑电平直接驱动：作为开漏开关或低端开关元件，用于与微控制器接口，减少外部元件。
- 指示/照明驱动：驱动低电流 LED 指示灯或背光。
- 信号隔离与缓冲：在数字总线、按键矩阵、传感器接口中用作缓冲和保护。
- 小信号开关：用于小电流继电器驱动、功率器件前级驱动或电平转换。
五、封装与使用注意
SOT-363 虽然体积小，但热阻较高，器件的 150 mW 功耗限制在 PCB 热管理上需注意：当长时间接近最大 Ic 或 Pd 时，应考虑降额使用或增加铜箔散热。内置基极电阻便于直接驱动，但若驱动电流或阻抗特殊（例如需要更快开关或更大电流），应在电路设计时评估实际开关性能并加入必要的外部限流或保护元件。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
