SERIES COMMERCIAL SENSITIVE TO-5 RELAYS 732 DPDT SERIES DESIGNATION RELAY TYPE 732 DPDT basic relay 732D DPDT relay with internal diode for coil transient suppression 732TN DPDT relay with internal transistor driver and coil transient suppression diode INTERNAL CONSTRUCTION DESCRIPTION The TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards for low-level switching from dry circuit to 1 ampere. Designed for high-density PC board mounting, the 732 relay is one of the most versatile ultraminiature relays available because of its small size and low coil power dissipation.

(4.50g) max. 732 Page 99 • All welded construction. • Unique uni-frame design providing high magnetic efficiency and mechanical rigidity. • High force/mass ratios for resistance to shock and vibration. • Advanced cleaning techniques provide maximum assurance of internal cleanliness. • Precious metal alloy contact material with gold plating assures excellent high current and dry circuit switching capabilities. The 732D relay has an internal discrete silicon diode for coil transient suppression. The hybrid Series 732TN relay has an internal silicon diode and transistor driver. The integrated packaging of the relay with its associated semiconductor devices greatly reduces PC board floor space requirements as well as component installation costs. By virtue of its inherently low intercontact capacitance and contact circuit losses, the 732 relay has proven to be an excellent ultraminiature RF switch for frequency ranges well into the UHF spectrum. A typical RF application for the TO-5 relay is in handheld radio transceivers, wherein the combined features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of Transmit-Receive switching (see Figure 1).
