Vishay Semiconductor Opto Division TLHK5800

Overview

TLHK5800 from Vishay Semiconductors is a high-intensity red AlInGaP LED in a 5 mm untinted non-diffused T-1¾ package, delivering 1000–5500 mcd luminous intensity at 20 mA, with ±4° viewing angle and 630 nm dominant wavelength. It serves as a status or indicator light in space-constrained, high-brightness applications requiring directional output.

For engineers reviewing the TLHK5800 datasheet, TLHK5800 pinout, TLHK5800 application, or TLHK5800 equivalent, key selection criteria include luminous intensity binning (e.g., EE–LL groups), narrow viewing angle for focused illumination, DC/peak-current operation up to 30 mA, and compatibility with standard 5 mm LED mounting and lightpipe coupling.

Technical Context

The TLHK5800 uses AlInGaP-on-GaAs epitaxy to achieve high radiance in the red spectrum, with dominant wavelength centered at 630 nm and peak at 643 nm. Its parabolic lens geometry enables ±4° half-intensity angle and high optical power density.

Thermal resistance is 350 K/W junction-to-ambient, supporting operation from –40 °C to +100 °C ambient. Absolute maximum ratings include 30 mA DC forward current, 5 V reverse voltage, and 80 mW power dissipation at ≤65 °C ambient.

FAQ

What is the luminous intensity range of the TLHK5800 and how is it binned?

The TLHK5800 has a luminous intensity range of 1000–5500 mcd at 20 mA, categorized into 13 standardized brightness groups (BB through UU). Each bag contains only one group-no mixing-and single-group orders are not supported to ensure supply continuity. The TLHK5800 shipped will fall within its assigned group's min/max values, such as EE (1000–2000 mcd) or LL (5750–11,500 mcd).

What is the viewing angle of the TLHK5800 and why does it matter for design?

The TLHK5800 has a ±4° angle of half intensity, meaning its light output is highly directional. This narrow beam improves coupling efficiency into lightpipes and reduces optical crosstalk in dense indicator arrays. For TLHK5800 designs, PCB layout must align the LED precisely with optical paths, and mechanical housings should avoid obstructing the parabolic lens profile.

Can the TLHK5800 be driven with PWM, and what are its surge current limits?

Yes, the TLHK5800 supports pulsed operation: absolute maximum surge forward current is 0.1 A for pulses ≤10 μs. This allows robust PWM dimming at typical frequencies (1–10 kHz) without thermal stress, provided average power stays within 80 mW. The TLHK5800's 350 K/W thermal resistance and 100 °C max junction temperature define safe duty-cycle limits under given ambient conditions.

What is the dominant and peak wavelength of the TLHK5800, and how do they affect color rendering?

The TLHK5800 has a dominant wavelength of 630 nm and a peak wavelength of 643 nm, both in the deep red band. Dominant wavelength defines human-perceived hue under photopic vision; peak wavelength indicates maximum spectral power. This combination ensures strong, saturated red output ideal for attention-grabbing indicators-critical for TLHK5800 use in medical alarms or safety status lights.

Does the TLHK5800 require special handling due to ESD sensitivity?

The TLHK5800 has an ESD-withstand voltage of 2 kV per JESD22-A114-B (HBM), which exceeds standard handling requirements for most assembly environments. No special ESD workstations are needed for TLHK5800 placement, though standard anti-static precautions-such as grounded wrist straps and dissipative mats-are still recommended to maintain long-term reliability and prevent latent damage.
