Products Description

0.5″ Single Digit Red 7-Segment LED Display – ZD-D12BWSR-1050C series

If you're building a counter, timer, voltage meter, or any small panel that just needs one clear red number, this 0.5 inch single digit red 7-segment LED display is the plain, reliable part you reach for. The character height is 12.7 mm (0.5″), through-hole DIP package, ready for standard 2.54 mm pitch PCBs - no driver IC, no fuss, just segments and current-limiting resistors.

We stock this 0.5″ red LED digit display under part number ZD-D12BWSR-1050C-L0. It's the kind of component engineers actually keep in the drawer: predictable forward voltage, stable brightness, RoHS compliant, and easy to solder by hand or wave.

What you're getting
0.5 inch 7 segment LED display single digit, red (dominant wavelength 620–640 nm)
Character height 12.7 mm, typical brightness 45 mcd @ 20 mA
Forward voltage 1.7–2.4 V, max continuous current 20 mA
Through-hole (DIP) mount, lead pitch matches 0.1″ (2.54 mm) board layout
Epoxy lens, wide viewing angle, good contrast for indoor panels
RoHS compliant, lead-free, original sealed pack

Where this 0.5″ red seven segment display fits
This isn't a fancy smart display. It's a workhorse:
Digital counters and pulse timers
Temperature / voltage / current readouts
Industrial control panels and relay boxes
Test gear, bench instruments, small appliances
Replacement digit for older 0.5″ 1 digit LED module boards

If your MCU (Arduino, STM32, 8051, PLC segment driver) already drives classic 7-seg digits, this single digit red LED segment display 0.5 inch drops straight in.

Why buyers pick this instead of a random "0.5 digit LED"
Consistent red hue across batches (620–640 nm band)
True 0.5″ (12.7 mm) character - not 0.39″ or 0.56″ mislabeled
DIP legs, no SMD rework needed
Works with standard 74HC595 / TM1637 / CD4511 layouts

If you've been searching for "0.5 inch single digit red LED display DIP", "12.7 mm 7 segment red digit", or "replace 0.5″ red 7 seg LED 1 digit" - this is the one.

FAQ:
Q: Is this common anode or common cathode?
A: We all have, can customized for you. Match your driver before wiring.
Q: Can I run it at 10 mA instead of 20 mA?
A: Yes. Brightness drops roughly linear; 10 mA still reads clearly indoors and saves power.
Q: Do you sell 2/3/4 digit 0.5″ red versions?
A: Same character height, multi-digit packages available on request - just ask for the matching SKU.
Q: What resistor do I use with 5 V supply?
A: (5 V – 2.0 V) / 20 mA ≈ 150 Ω per segment; adjust for your actual VF and desired current.
