In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits. TO stands for "Transistor Outline" and relates to a series of …

TO56也就是说,TO底座的外径为5.6mm的一种封装方式。 主要的应用范围就是常规光器件，因为5.6mm大小适中，与常规的 SFP模块 、 XFP模块 结构均能够吻合，所以得到了巨大的发展。 目前主要应用于 LD-TO器件。 2、常规的TO46和TO52. TO46主要应用于 PD-TO。 其实早期PD也使用TO56，是因为光器件收端从焊接工艺切换为胶水工艺后，由于体积要求减少，而使用的TO46。 3、TO38. TO38封装主要应用与小型10G或者25G光器件，因为更小的体积可以制造出更小的 …

The TO-3 package (TO-204AA) features a hermetically sealed metal can, providing excellent environmental protection and mechanical strength. It includes up to 4 leads and offers efficient heat dissipation, making it ideal for high-power applications.

The TO-3 or TO3 is a type of 'metal can' package that is capable of high-power dissipation commonly used by power transistors, SCR's and other high-power semiconductor devices. The TO-3 is made entirely of metal, with the microchip mounted on its metal can base and then covered with a metal cap.

玻璃-金属密封的 TO can——可靠的密封性 数十年来， 玻璃-金属密封 一直是制造真空密封封装的首选技术。 与非气密性聚合物或准气密性聚合物封装相比，玻璃气密性密封的主要优点是：
