The global indicator LED market is projected to grow at 5.2% CAGR (2023-2030) according to Market Research Future. Key drivers include:
Increasing demand for energy-efficient lighting in IoT devices
Miniaturization trends favoring compact packages
Growth in industrial automation requiring reliable status indicators
The TLHR4605-MS12Z addresses these needs with its low power consumption (2.4V forward voltage) and standardized form factor.
A: Vishay rates these LEDs for 100,000 hours at nominal current (20mA) when operated within specified temperature ranges.
A: While it meets basic environmental requirements, for automotive primary functions, consider AEC-Q102 qualified alternatives from Vishay's automotive line.
A: The TLHR4605-MS12Z is only available with green emission (569nm). Vishay offers other colors in the TLxR series.
A: Per IPC/JEDEC J-STD-020, maximum peak temperature should not exceed 260°C for 10 seconds in wave soldering applications.
A: Diffusion creates uniform light distribution, eliminating hot spots and making the LED visible from all angles within its 120° viewing cone.
Vishay continues to advance LED technology with:
Higher efficiency versions maintaining brightness at lower currents
Expanded color gamut for specialized applications
Hybrid packages combining multiple LEDs in single components
