Complete LED Diode Model Guide: SMD / Through-Hole / High-Power Quick Reference (0402-5050)
LED diodes come in a huge variety of models, colors, and packages, and buyers typically search by "model + color + application." As a factory-direct LED packaging manufacturer, Hongcheng Optoelectronics has organized the most common models and typical search terms into this quick reference, so engineers and buyers can find what they need fast.
1. Small SMD (0402 / 0603 / 0805)
The 0402 series suits high-density PCBs: 0402 red, 0402 green, and 0402 blue are all in stock. The 0603 series is the most widely used size, covering 0603 red, 0603 pure green, and 0603 white; 0603 LED indicators are everywhere in home appliances and instruments. The 0805 series offers higher brightness, and 0805 dual-color SMD diodes are a common choice for status-switching indication.
2. Mid-Size and Side View (1204 / 1206 / 2835 / 3014 / 3528 / 4014 / 5630 / 5730)
The 1204 side-view is the first choice for ultra-thin panels, with stable supply of 1204 dual-color and 1204 orange-blue dual-color diodes. The 1206 series offers high-brightness LEDs. 3014 side-view and 4014 LEDs serve backlighting and indication. 3528 dual-color diodes are a classic indicator solution. 2835 SMD diodes cover 2835 white and 2835 red — as a 2835 diode manufacturer, Hongcheng supports custom binning. 5630 and 5730 SMD diodes cover higher-brightness applications.
3. Full Color and High Power (5050 / 3535 / 3030 / COB / Luxeon-style)
5050 RGB diodes, 5050 RGBW, and 5050 full-color diodes (also called 5050 RGB full-color diodes) are used in smart speakers, gaming devices, and ambient indication. The 3535 LED family includes 3535 RGB, 3535 ceramic, and 3535 high-power series. 3030 LED and 3030 EMC diodes focus on high reliability. High-power options cover 1W, 3W, and 5W LEDs plus Luxeon-style diodes. COB integrated light sources and COB surface-emitting diodes serve area lighting. Ceramic 3535, ceramic LED, and EMC leadframe diodes handle high-temperature scenarios.
4. Through-Hole Series (3mm / 5mm)
The F3 LED series includes 3mm red-diffused, 3mm white-diffused, and similar lens structures. The F5 LED series includes 5mm high-brightness LEDs and 5mm through-hole diodes, well suited to traditional home appliances and industrial control panels.
5. Colors and Special Wavelengths
Single colors cover yellow, orange, and pink LEDs. Dual colors cover red-blue dual-color diodes and orange-blue dual-color SMD diodes. Special wavelengths cover UVA, UVB, and UVC 3535 ultraviolet solutions, as well as deep-UV sterilization diodes.
6. Typical Applications
Home appliances: washing machine LED indicators, air conditioner indicators, induction cooker indicators. Consumer electronics: keyboard backlight diodes. Industrial: equipment status and power indication.
7. Parameter-Based Quick Selection
Brightness: high-brightness indicator LEDs and ultra-bright SMD LEDs, binned by mcd. Voltage: low-voltage LEDs, 3V diodes, 12V diodes, high-voltage diodes. Power: low-power, mid-power, 0.2W and 0.5W diodes. Reliability: low-lumen-depreciation diodes, wide-temperature LEDs (-40°C to +85°C), gold-wire diodes, gold-plated and silver-plated substrate diodes, flip-chip LEDs, and CSP packages.
8. How to Choose a Manufacturer
When searching for top Chinese LED diode brands or the best LED diode supplier, focus on three things: whether it is a true factory-direct source, whether it provides complete datasheets, and whether it supports non-standard and custom-mold diode development. Hongcheng Optoelectronics is located in Dongguan, serving customers across the Pearl River Delta (Shenzhen, Guangzhou, Zhongshan) and overseas markets, offering high-quality LED diodes with free sampling and testing.
