Applications
The HDSP-C3E3 is used in industrial process control panels, laboratory instruments, and test equipment where a bright, easily readable single-digit numeric display is required. Its common-cathode configuration simplifies interfacing with standard 7-segment decoder/driver ICs such as the 74LS47 or MAX7219 in multiplexed display systems. The high-reliability rating and 9.1 mm digit height also make it suitable for benchtop power supplies, frequency counters, and embedded system debug display modules.

Frequently Asked Questions
How does the common-cathode configuration of the HDSP-C3E3 affect the circuit required to drive it?
In a common-cathode 7-segment display, all segment cathodes share a common ground connection, and individual segments are lit by applying a positive voltage through a current-limiting resistor to each anode. This suits active-high microcontroller GPIO outputs and standard 7-segment decoder ICs such as the 74HC4511 or MAX7219 that source current through segment anodes. Each lit segment requires a 25 mA maximum forward current at up to 2.3V, so a series resistor of approximately 47 ohms on a 3.3V rail or 120 ohms on a 5V rail will set a safe 10 to 15 mA operating current.
At what viewing distance is the 9.1 mm digit height of the HDSP-C3E3 legible to operators?
A 9.1 mm digit height is comfortably legible at distances of 1 to 2 meters under normal indoor lighting, which covers most benchtop instrument and panel-mounted readout applications. For larger control rooms or wall-mounted displays requiring readability beyond 3 meters, a display with a digit height of 20 mm or greater would be needed. The orange-red emission wavelength of the HDSP-C3E3 provides good contrast against typical gray or black instrument panel backgrounds, further aiding legibility within its designed range.
Can the HDSP-C3E3 be multiplexed with other display digits to build a multi-digit numeric readout?
Yes. The common-cathode architecture of the HDSP-C3E3 is designed for multiplexed operation, where each digit's cathode is connected to a separate digit-select transistor and all segment anodes are bused together across digits. At a 25 mA peak segment current and a typical 4-digit multiplex duty cycle of 25%, the average current per segment is about 6.25 mA, producing acceptable brightness for most indoor environments. Drive ICs such as the MAX7219 or HT16K33 directly support multiplexed common-cathode 7-segment displays and simplify SPI or I2C control from a microcontroller.
What operating temperature range does the HDSP-C3E3 support, and is it suitable for industrial enclosures?
Avago HDSP series 7-segment displays are typically rated from -40°C to +85°C operating temperature, covering standard industrial temperature class requirements. The high-reliability construction of the HDSP-C3E3 and its REACH-compliant Pb-free packaging make it suitable for use in industrial enclosures, factory automation HMI panels, and measurement equipment that must operate reliably in environments with temperature cycling, humidity, and vibration. Designers should verify the exact thermal rating in the Avago/Broadcom datasheet for the specific application.
