Applications
The LTW-5630AZL40 is used in LED panel backlights, display indicator arrays, and architectural accent lighting where neutral-white 5630-size LEDs provide high lumens-per-footprint efficiency in a surface-mount form factor. Industrial control panels and HMI displays deploy it for status indicators and keypad illumination, leveraging its IC-compatible drive level to eliminate external level-translation components. Consumer electronics manufacturers also choose it for portable device displays and appliance lighting where the built-in Zener diode provides robust ESD immunity during assembly and field handling.

Frequently Asked Questions
What is the forward voltage and current rating of the LTW-5630AZL40, and how should a current-limiting resistor be calculated for a 5 V supply?
The LTW-5630AZL40 has a maximum forward voltage of 3.3 V and a maximum forward current of 200 mA. For a 5 V supply driving the LED at a typical 100 mA operating current, the series resistor value is (5 V − 3.3 V) / 100 mA = 17 Ω, with a power dissipation of 170 mW, so a 0402 or 0603 resistor rated at 250 mW is appropriate.
What ESD protection level does the built-in Zener diode in the LTW-5630AZL40 provide?
The integrated Zener diode in the LTW-5630AZL40 clamps electrostatic discharge transients, typically providing protection against ESD events up to ±2 kV per the Human Body Model (HBM). This eliminates the need for an external TVS diode on each LED in PCB designs where assembly-line handling or end-user contact can generate ESD pulses above the bare LED junction's breakdown threshold.
Can the LTW-5630AZL40 be driven directly by a microcontroller GPIO, and what resistor value is needed at 3.3 V?
Yes, the LTW-5630AZL40 is marked as IC-compatible. At a 3.3 V supply, the LED forward voltage of approximately 3.0 V to 3.3 V leaves only 0 V to 0.3 V across an external resistor, so direct GPIO drive at full 200 mA is not practical. For indicator use at 5 mA to 20 mA, a 5 V rail with a 68 Ω to 100 Ω series resistor, or a MOSFET-driven 3.3 V rail, is the standard approach.
How does the 5630 package size of the LTW-5630AZL40 compare to 3528 and 5050 LEDs in terms of thermal performance?
The 5630 package measures 5.6 mm × 3.0 mm, giving it a larger copper bonding pad area than the 3528 (3.5 mm × 2.8 mm), which reduces thermal resistance by approximately 20% and allows the LED to dissipate more heat at the same junction temperature. Compared to the 5050 (5.0 mm × 5.0 mm), the 5630 occupies 34% less board area while still supporting up to 200 mA, making it a favorable trade-off between brightness and PCB space.
