TQ2SA-5V-Z Introduction

The double pole, double throw (DPDT) TQ2SA-5V-Z relay has two form C contacts and is a type of telecom relay. It is the perfect option for applications that need high performance and reliability in a small package because it is surface-mountable.

Telecom relays are frequently employed in telecom and data transmission equipment to switch signals between various circuits or components. As a high-performance relay with low power consumption that can switch high voltages and currents, the TQ2SA-5V-Z is appropriate for various applications.

Among its important characteristics is the TQ2SA-5V-Z relay’s small size and surface-mount package, which make it simple to integrate into electronic circuits and devices. A mechanical endurance of 1 x 107 operations and an electrical endurance of 1 x 105 operations further demonstrate its excellent dependability and durability.

The TQ2SA-5V-Z relay’s specs, pin configuration, size, applications, operational requirements, and ordering information are covered in detail in the following sections.


  • 3 types of terminal shapes:
  • Terminal for PC boards (standard/self-clinching).
  • terminal for surface mounting.
  • Comfort to FCC Part68:
  • 1,500 V surge withstand (between open contacts).
  • Contact information for M.B.B.
  • Surface-mount terminals meet JIS 0806 requirements.

Pin configuration

The TQ2SA-5V-Z relay has 8 pins, arranged in two rows of 4 pins each. The pin configuration is as follows:

  • Pin 1: Coil 1
  • Pin 2: Coil 1
  • Pin 3: Coil 2
  • Pin 4: Coil 2
  • Pin 5: Normally open (NO) contact of switch 1
  • Pin 6: Common contact (COM) of switch 1 and normally closed (NC) contact of switch 2
  • Pin 7: Normally open (NO) contact of switch 2
  • Pin 8: Common contact (COM) of switch 2 and normally closed (NC) contact of switch 1

With the coil pins in the middle and the contact pins on either side, the pins are placed in a symmetrical configuration. Coil pins for coils 1 and 2 are represented by pins 1 and 2, and coil pins for coils 3 and 4 by pins 3 and 4. By applying a voltage to the coil and turning on the relay, the coil pins do this.

Signals are switched between various circuits or components using the contact pins. The contacts for switch 1 are pins 5 and 6, with pin 5 being the normally open (NO) contact and pin 6 serving as both the common contact (COM) and usually closed (NC) contacts for switches 1 and 2, respectively. The contacts for switch 2 are pins 7 and 8, with pin 7 serving as the ordinarily open (NO) contact and pin 8 serving as both the common contact (COM) and the normally closed (NC) contact for switch 2 and switch 1, respectively.

Overall, the TQ2SA-5V-Z relay’s pin layout enables accurate switching between different circuits or components with good performance and dependability.
