TLL.440 is a low power LED produced by Vishay Telefunken. It has high brightness, CMOS/MOS compatibility and other features. It is suitable for low power DC circuits.
The TLL.440 family consists of low‑current 3 mm tinted diffused LEDs in red (TLLR440), yellow (TLLY440) and green (TLLG440) versions. They feature low power consumption, high brightness, and CMOS/MOS compatibility, making them suitable for low‑power DC circuits.
The document lists detailed electrical characteristics (forward voltage, reverse voltage, forward current, luminous intensity, wavelength), absolute maximum ratings, typical performance curves, mechanical dimensions, and Vishay’s ozone‑depleting substances policy. All parameters are given for a test current of 2 mA unless otherwise noted.
| Reverse voltage (Va) | 6 V |
|---|---|
