产品概述:SMMBTA56LT1G PNP 三极管
SMMBTA56LT1G 是安森美(ON Semiconductor)生产的一款高性能PNP型BJT三极管。作为一种小型表面贴装型元器件,该产品在现代电子设备中广泛应用,特别是在需要高可靠性和高效能的环境中,适用于开关电源、放大器、信号处理和其他多种电子电路设计。
功率: SMMBTA56LT1G的最大功率为225mW,使其能够在多种电气环境中运行而不会遭受损坏。这一特性使其适合用于功率相对较低的应用场景,例如小型感测设备、便携式仪器和低功耗通信电路。
额定电流和电压: 该三极管的集电极(Ic)最大电流为500mA,适合中等功率负载的控制。此外,其集射极击穿电压(Vce)最大值可达80V,这使其能够承受较高的电压,从而提高了应用的灵活性与安全性。
饱和压降: 产品的饱和压降(Vce)在不同集电极电流(Ic)的情况下可达到最大值250mV,这在Ic为10mA和100mA时保持一致。较低的饱和压降意味著在开关应用中,功耗会更低,整体效率更高。
频率性能: SMMBTA56LT1G具有50MHz的跃迁频率,非常适合用于高频信号的放大和切换需求。这一频率响应性能使其尤其适合于RF(射频)和高速数据信号处理应用。
工作温度范围: 该三极管的工作温度范围为-55°C至150°C,适合在严酷环境下使用。如此宽泛的温度范围使得SMMBTA56LT1G可在汽车电子、航空航天及工业控制等行业中得到有效应用。
电流增益: 在额定条件下(Ic为100mA,Vce为1V),SMMBTA56LT1G的直流电流增益(hFE)最小值为100,确保了在驱动负载时良好的性能。这一特性保证了该元件在放大应用中的有效性和稳定性。
极小的集电极截止电流: SMMBTA56LT1G的集电极截止电流(最大值)为100nA,确保其在关断状态下的漏电流极低,增加了电路的整体功效,并延长了电池供电应用的使用寿命。
SMMBTA56LT1G采用SOT-23-3封装,这是一种流行的小型表面贴装封装形式,使得元件在电路板上的占用空间更小,适合于现代紧凑型电子设备设计。三脚方式的设计使其安装简便,能够很好地集成到自动化贴装生产线中。
该三极管广泛应用于多个领域,包括:
综上所述,SMMBTA56LT1G是一款兼具高性能和高可靠性的PNP型三极管,涵盖了广泛的应用场景。从功率、频率到工作环境的适应性,这款产品在市场中极具竞争力。它的设计理念不仅考虑了电气特性,也充分考虑了现代产品对空间和效率的需求,使其成为设计师和工程师的理想选择。
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.
