DESCRIPTION

The TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards f or lo w-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. The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability:

  • 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).

Relay contacts will exhibit no chatter in excess of 10 µsec or transfer in excess of 1 µsec. 2. “Typical” characteristics are based on available data and are best estimates. No on-going verification tests are performed. 3. Unless otherwise specified, parameters are intial values. 4. For Reference Only. Coil resistance not directly measurable on 732TN relays. 5. Circuit is typical for all Series 732TN. Values shown are for 732TN-5 relay and apply for full temperature range. Limit base-emitter current to 15 mADC. 6. Unless otherwise specified, relays will be supplied with either gold-plated or solder-coated leads. 7. The slash and characters appearing after the slash are not marked on the relay. Vcc Vr Notes: Logic 1 activates the relay. Logic 0 de-activates the relay. Vcc = logic bias power. Vr = coil energization voltage. Pin 10 Pin 9 Pin 1 Logic element 1 = 0.24 to 1.50mA 0 = 0.3Vdc min.
