1N4954US thru 1N4996US, 1N5968US thru 1N5969US, and 1N6632US thru 1N6637US SCOTTSDALE DIVISION VOIDLESS-HERMETICALLY-SEALED Surface Mount 5 WATT GLASS ZENER DESCRIPTION This surface mount Zener Voltage Regulator series is military qualified to MIL-PRF-19500/356 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 5 Watt Zener Voltage Regulators are hermetically sealed with voidless-glass construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 390 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. They are also available in axial-leaded packages for thru hole mounting by deleting the “US” suffix (see separate data sheet for 1N4954 thru 1N4996, 1N5968 thru 1N5969, and 1N6632 thru 1N6637). Microsemi also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.

物料型号： - 1N4954US 至 1N4996US - 1N5968US 至 1N5969US - 1N6632US 至 1N6637US

器件简介：这是一系列军用级别的表面贴装Zener电压调节器，符合MIL-PRF-19500/356标准，适用于高可靠性的应用场合。这些行业认可的5瓦Zener电压调节器采用无空洞玻璃结构进行真空密封，使用内部冶金键合。包括从3.3至390伏的标准5%公差Zener选择，以及通过不同的后缀字母标识的更紧密公差。它们也可以在删除“US”后缀的情况下提供轴向引脚封装，用于通孔安装。

引脚分配： - 阳极通过带状标识表示。

参数特性： - 流行的JEDEC注册系列。 - 无空洞密封玻璃封装。 - 三层钝化。 - 内部冶金键合，1N4954US至1N4996US为“Category I”，1N6632US至1N6637US以及1N5968US至1N5959US为“Category III”。 - 根据MILPRF-19500/356提供JAN、JANTX、JANTXV和JANS版本。 - 提供轴向引脚等效型号。

功能详解： - 工作温度范围：-65°C至+175°C。 - 存储温度范围：-65°C至+175°C。 - 功率耗散：5瓦特@TEC=125°C，并在超过125°C时每增加1°C TEC线性降低0.1W。 - 热阻：1N4954US至1N4996US为7°C/W，1N6632US至1N6637US以及1N5968US至1N5969US为10°C/W。 - 10ms时的热阻抗：1N4954US至1N4996US为1.8°C/W，1N6632US至1N6637US和1N5968US至1N5969US为3.0°C/W。 - 正向电压：1.50V@1.0A。

应用信息： - 在广泛的工作电流和温度范围内调节电压。 - 广泛的电压选择，从3.3至390V。 - 标准电压公差为±5%，无后缀。 - 提供±2%或±1%的紧密公差，分别用C或D后缀标识。 - 结构非常坚固。 - 根据MIL-STD-750方法1020，对ESD不敏感。 - 固有的抗辐射特性，如Microsemi MicroNote 050所述。

封装信息： - 封装：采用无空洞硬质玻璃密封，带有钨塞。 - 端帽：实心银（Ag）镀锡/铅（Sn/Pb）。 - 标记：无。 - 极性：通过带状标识阳极。 - 胶带和卷轴选项：符合EIA-481-B标准，重量为539毫克。
