SOA PROTECTIONDESCRIPTIONThe L7800series of three-terminal positive regulators is available in TO-220ISOWATT220TO-3and D 2PAK packages and several fixed output voltages,making it useful in a wide range of applications.These regulators can provide local on-card regulation,eliminating the distribution problems associated with single point regulation.Each type employs internal current limiting,thermal shut-down and safe area protection,making it essentially indestructible.If adequate heat sinking is provided,they can deliver over 1A output current.Although designed primarily as fixed voltage regulators,these devices can be used with external components to obtain adjustable voltages and currents.12TO-3123TO-220ISOWATT22012313D 2PAKBLOCK DIAGRAM1/25CONNECTION DIAGRAM AND

TCA785参数规格书及应用
TCA785P规格书及运用TCA785是德国西门子(Siemens)公司于1988年前后开发的第三代晶闸管单片移相触发集成电路，它是取代TCA780及TCA780D的更新换代产品，其引脚排列与TCA780、TCA780D和国产的KJ785完全相同，因此可以互换。
目前，它在国内变流行业中已广泛应用。
与原有的KJ系列或KC系列晶闸管移相触发电路相比，它对零点的识别更加可靠，输出脉冲的齐整度更好，而移相范围更宽，且由于它输出脉冲的宽度可人为自由调节，所以适用范围较广。
一、引脚排列、各引脚的功能及用法TCA785是双列直插式的16引脚大规模集成电路。
它的引脚排列如图1所示。
图1TCA785的引脚排列(脚朝下)各引脚的名称、功能及用法如下:引脚16(VS)：电源端。
使用中直接接用户为该集成电路工作提供的工作电源正端。
引脚1(OS)：接地端。
应用中与直流电源VS、同步电压VSYNC及移相控制信号V11的地端相连接。
引脚4(Q1)和2(Q2)：输出脉冲1与2的非端。
该两端可输出宽度变化的脉冲信号，其相位互差180°，两路脉冲的宽度均受非脉冲宽度控制端引脚13(L)的控制。
它们的高电平最高幅值为电源电压VS，允许最大负载电流为10mA。
若该两端输出脉冲在系统中不用时，电路自身结构允许其开路。
引脚14(Q1)和15(Q2)：输出脉冲1和2端。
该两端也可输出宽度变化的脉冲，相位同样互差180°，脉冲宽度受它们的脉宽控制端引脚12(C12)的控制。
两路脉冲输出高电平的最高幅值为VS。
引脚13(L)：非输出脉冲宽度控制端。
该端允许施加电平的范围为-0.5V~VS，当该端接地时，Q1、Q2为最宽脉冲输出，而当该端接电源电压VS时，Q1、Q2为最窄脉冲输出。
引脚12(C12)：输出Q1、Q2脉宽控制端。
应用中，通过一电容接地，电容C12的电容量范围为150~4700pF，当C12在150~1000pF范围内变化时，Q1、Q2输出脉冲的宽度亦在变化，该两端输出窄脉冲的最窄宽度为100μs，而输出宽脉冲的最宽宽度为2000μs。

StellarNet便携式拉曼光谱仪性能介绍与参数一览
StellarNet便携式拉曼光谱仪性能介绍与参数一览型号HR-TEC-785的拉曼光谱仪是StellarNet生产制造的一款大受欢迎的拉曼光谱仪，特色在于它的参数非常广泛波长范围00-3200cm-1，同时整合整套拉曼光谱系统价格实惠，是大多数想购买拉曼光谱仪，搭建拉曼光谱系统的理想选择.StellarNet提供了应用于200-3200cm-1的各种便携式拉曼光谱仪，可以快速识别各种液体，固体或粉末样品。
其中785nm 激光是拉曼光谱选择的最常见波长。
因为这段波长是红外激光在拉曼效率，荧光效应和吸热这3种反应中，依旧能保持平衡的波长。
同样，785nm激光器通常比其他频率便宜，从而使整个光谱系统的价格变得较为经济实惠。
Raman-HR-TEC-785拉曼光谱仪是stellarNet大受欢迎的拉曼光谱仪，包括针对785nm拉曼调谐的增强型CCD阵列检测器和先进的检测器透镜组件，可在长时间曝光时实现超高灵敏度。
StellarNet拉曼光谱仪Raman-HR-TEC-X2-785提供2级检测器冷却功能，以实现最高的灵敏度和性能！非常适合长时间曝光，曝光最多可达8分钟。
可互换的狭缝（Interchangeable Slits Upgrades），可用于高分辨率HR光学平台，以提供更多的应用灵活性。
可以使用最小的狭缝来测量高散射样品，以获得极高的分辨率，也可以通过较大的狭缝来测量弱拉曼，以增加光通量。
Stellar CASE-Raman-785是一款便携式，坚固耐用的拉曼光谱系统，适用于“开放与测量”应用。
这个完整的系统包括高性能拉曼光谱仪（Raman-HR-TEC-785），大功率激光器和样品瓶架。
通常建议将Raman-SR-785系列光谱仪用于OEM和便携式应用，在这些应用中已知特定样品组并且在不使用检测器冷却的情况下也能很好地工作。

DESCRIPTION The L7800 series of three-terminal positive regulators is available in TO-220, TO-220FP, TO-220FM, TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
