Vishay Semiconductor Opto Division TLVD4200

Overview

TLVD4200 from Vishay Semiconductors is a high-brightness red LED optimized for backlighting applications using double heterojunction (DH) GaAlAs-on-GaAs technology, with 40–130 mlm luminous flux at 15 mA, ±85° viewing angle, and 1.8–2.2 V forward voltage at 20 mA. It features a tinted clear 3 mm non-diffused package and is engineered for uniform illumination of display panels and switch symbols.

For engineers reviewing the TLVD4200 datasheet, TLVD4200 pinout, TLVD4200 application, or TLVD4200 equivalent, key selection considerations include luminous flux binning (U–Z groups), DH red spectral output (640 nm dominant, 650 nm peak), thermal resistance (400 K/W), and absolute maximum ratings including 50 mA DC forward current and 100 °C junction temperature.

Technical Context

The TLVD4200 operates as a visible-light emitter in the red spectrum, leveraging DH GaAlAs-on-GaAs semiconductor structure to achieve high radiance and low self-heating. Its spatial radiation pattern-shaped by the 3 mm package geometry and ±85° half-intensity angle-is specifically qualified for backlighting tasks requiring wide-angle, directional emission without diffusion.

Designed for continuous or pulsed DC operation up to 50 mA, the device maintains stable optical output across –40 °C to +100 °C ambient range, with junction-to-ambient thermal resistance of 400 K/W enabling reliable performance in compact, thermally constrained backlight assemblies.

FAQ

What is the dominant wavelength of the TLVD4200?

The TLVD4200 has a dominant wavelength of 640 nm, measured at 10 mA forward current. This value places its output in the deep red portion of the visible spectrum, ensuring high visibility and color consistency for backlighting applications such as LCD panels and switch legends. The peak wavelength is 650 nm, confirming spectral alignment with standard red indicator requirements.

What luminous flux binning options are available for the TLVD4200?

The TLVD4200 is categorized into luminous flux groups U through Z, with group U specifying 40–80 mlm and group Z specifying 240–480 mlm at 15 mA. Each order bag contains only one flux group - no mixing occurs - and single-group orders are not supported to ensure supply continuity. TLVD4200 shipments default to standard binning unless otherwise specified.

Can the TLVD4200 be driven at 50 mA continuously?

The TLVD4200 supports a maximum DC forward current of 50 mA per its Absolute Maximum Ratings, but sustained operation at this level requires strict thermal management. At Tamb ≤ 60 °C, power dissipation must remain ≤100 mW, limiting practical continuous drive to ~45 mA depending on VF and ambient conditions. Pulse operation allows higher peak currents if duty cycle and pulse width comply with Fig. 2 in the datasheet.

What is the viewing angle specification for the TLVD4200?

The TLVD4200 has an angle of half intensity of ±85°, meaning luminous intensity drops to 50% of its on-axis value at 85° off-center in both directions. This wide viewing angle is achieved via its DH red chip geometry and 3 mm package shape, making it ideal for backlighting applications where uniform illumination across broad surfaces is required without additional diffusers or reflectors.

Is the TLVD4200 RoHS-compliant and halogen-free?

Yes, the TLVD4200 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (document 99912). The device uses lead-free solderable leads and meets JEDEC J-STD-020 moisture sensitivity level 1, supporting standard reflow profiles without preconditioning. Compliance documentation is available upon request from Vishay's website or Aetrix Electronics support.
