T9AS1D12-12
Overview
The T9AS1D12-12 is a power PCB relay from TE Connectivity's P&B line, designed for high-current switching in industrial and appliance applications. It features a single-pole normally-open (SPST-NO) contact configuration and is driven by a 12VDC coil. This relay is widely recognized for its ability to handle significant power loads while maintaining a compact footprint for through-hole mounting.
Why Choose This Part
This relay offers high isolation and robust contact performance, meeting stringent UL/CSA and VDE requirements for safety-critical power switching. Its sealed construction option allows for wave soldering and cleaning processes, making it suitable for high-volume automated assembly. The T9A series is specifically optimized for high-inrush loads common in motor and inductive applications.
Applications
Key Specifications
Getting Started
When designing with this relay, ensure PCB trace widths are sufficient to handle the rated switching current to prevent overheating. Use a flyback diode (such as a 1N4007) across the 12V coil to protect the driving transistor from inductive spikes. Verify that the clearance and creepage distances on your PCB layout meet the insulation requirements of your target industrial or appliance safety standard.
