Key Features
- 2-digit common cathode 7-segment yellow LED display with decimal points, enabling direct interfacing with standard segment driver ICs without additional inversion logic
- 14.2 mm character height providing high visibility in industrial panel meters, test equipment, and bench instruments at typical viewing distances of 1 to 3 meters
- Maximum forward current of 20 mA per segment at up to 2.4 V forward voltage, compatible with 3.3 V and 5 V logic drive circuits with simple current-limiting resistors
Applications
The HDSP-523Y is well suited for numeric readout panels in industrial instruments, laboratory bench meters, and embedded controller status displays where a bright yellow 2-digit LED output is required. Its DIP-18 package allows direct insertion into standard DIP sockets for easy prototyping and field replacement in test and measurement equipment. The common cathode configuration and 14.2 mm digit height make it a practical choice for counters, timers, and process control panels operated in moderately lit industrial environments.

Frequently Asked Questions
What digit configuration and character height does the HDSP-523Y provide for panel display applications?
The HDSP-523Y is a 2-digit common cathode 7-segment display with decimal points and a character height of 14.2 mm. This size is easily readable at distances of 1 to 3 meters, making it suitable for instrument panels, process controllers, and benchtop test equipment where clear numeric readout is required.
What are the electrical limits for driving each segment of the HDSP-523Y?
Each segment has a maximum forward current of 20 mA and a maximum forward voltage of 2.4 V. A designer using a 5 V supply with a 150 Ω current-limiting resistor per segment achieves approximately 17 mA drive current, producing adequate brightness while staying within the 20 mA per-segment limit.
How does the common cathode configuration of the HDSP-523Y simplify driver circuit design?
With common cathode wiring, both digit cathodes share a common ground reference, allowing the designer to use sourcing (high-side) driver outputs on the segment anodes without an inverter stage. This is directly compatible with most segment decoder ICs and microcontroller GPIO pins configured as push-pull outputs driving at 3.3 V or 5 V.
For which types of equipment is the HDSP-523Y yellow color preferred over red or green alternatives?
Yellow LEDs at approximately 585 nm wavelength provide good contrast against both light and dark backgrounds and are less fatiguing under extended viewing than pure red. The HDSP-523Y yellow output is favored in warning indicator panels, frequency counters, and industrial process readouts where the operator must distinguish the display from green status lights or red alarm indicators nearby.
