Vishay Semiconductor Opto Division TLCR6800

Overview

TLCR6800 from Vishay Semiconductors is a red ultrabright AlInGaP-on-GaAs LED in a 5 mm clear, non-diffused package with ±4° viewing angle, 7500–35,000 mcd luminous intensity at 50 mA, and dominant wavelength 611–622 nm - designed for high-visibility indicator and signal applications including CHMSL and traffic signals.

For engineers reviewing the TLCR6800 datasheet, TLCR6800 pinout, TLCR6800 application, or TLCR6800 equivalent, key selection criteria include its narrow-beam optical profile, high junction temperature rating (125 °C), ESD robustness (2 kV HBM), luminous intensity binning, and compatibility with 50 mA constant-current drive in harsh ambient environments.

Technical Context

The TLCR6800 employs AlInGaP semiconductor technology on a GaAs substrate to deliver high-efficiency red emission with tight spectral control (Δλ = 18 nm FWHM) and low thermal drift (TCλd = 0.05 nm/K). Its parabolic lens geometry enables ±4° half-intensity angle and peak intensity at 622 nm.

Rated for continuous operation up to 125 °C junction temperature and 50 mA DC forward current, the device features a thermal resistance of 300 K/W and supports surge currents up to 1 A (10 μs pulse), making it suitable for automotive-grade indicator duty cycles with minimal derating.

FAQ

What is the maximum continuous forward current rating for TLCR6800?

The TLCR6800 is rated for 50 mA DC forward current at ambient temperatures ≤85 °C. Exceeding this requires derating per Fig. 1 in the datasheet - e.g., at 100 °C ambient, max IF drops to ~32 mA. The device supports 1 A surge current for pulses ≤10 μs, useful for strobe or PWM peak driving. Always maintain junction temperature ≤125 °C using thermal design margins.

Does TLCR6800 have a built-in current-limiting resistor?

No, the TLCR6800 is a bare LED die in a 5 mm package with no integrated current-limiting resistor. It must be driven by an external constant-current source or properly sized series resistor. At 50 mA and typical VF of 2.1–2.7 V, a 47 Ω–100 Ω resistor is typical with 5 V supply; thermal stability of the resistor and PCB layout must be considered for long-term intensity consistency.

What does "untinted non-diffused" mean for TLCR6800's optical performance?

"Untinted non-diffused" means the TLCR6800 uses a clear, colorless polycarbonate lens with no pigment or scattering additives - preserving raw die output with minimal absorption or angular dispersion. This yields a narrow ±4° half-intensity beam and peak luminous intensity up to 35,000 mcd, unlike diffused variants that trade intensity for wider viewing angles.

How is luminous intensity binned for TLCR6800, and why does it matter?

TLCR6800 is shipped in single-intensity bags where IV_max/IV_min ≤ 2.0 - e.g., an "MM" bin contains 7500–15,000 mcd units. This guarantees brightness uniformity across LEDs in the same bag, eliminating post-assembly sorting for displays or arrays. Bins like "SS" (32,000–64,000 mcd) enable high-end applications needing maximum output without sacrificing consistency.

Can TLCR6800 be used in reverse-bias configurations?

The TLCR6800 has a 5 V maximum reverse voltage rating and is not designed for sustained reverse conduction. However, the datasheet notes reverse driving is suitable for short-term applications - e.g., brief reverse pulses in multiplexed displays where cathode/anode roles alternate. Continuous reverse bias risks degradation; always limit IR to <10 μA and duration to milliseconds.
