Vishay Semiconductor Opto Division TLVG4200

Overview

TLVG4200 from Vishay Semiconductors is a green backlighting LED in a 3 mm tinted non-diffused package, designed for uniform panel illumination with ±85° viewing angle, 10–30 mlm luminous flux at 15 mA, and 562–575 nm dominant wavelength using GaP-on-GaP technology.

For engineers reviewing the TLVG4200 datasheet, TLVG4200 pinout, TLVG4200 application, or TLVG4200 equivalent, this device supports low-power, high-reliability backlighting in space-constrained industrial displays, switch indicators, and measurement scales where spectral accuracy and wide-angle emission are critical.

Technical Context

The TLVG4200 operates as a discrete visible-light emitter with forward voltage of 2.4–3.0 V at 20 mA and absolute maximum DC forward current of 30 mA at ≤60 °C ambient. Its optical output is characterized by dominant wavelength (562–575 nm) and peak wavelength (555 nm), confirming green spectral purity optimized for human-eye sensitivity in indicator applications.

Thermal performance is defined by junction-to-ambient thermal resistance of 400 K/W and maximum junction temperature of 100 °C, enabling stable operation across –40 to +100 °C ambient range. The device uses a standard 3 mm radial-leaded package with non-diffused lens and tinted clear epoxy, supporting direct mounting without secondary optics in most backlight configurations.

Key Specifications

FAQ

What is the maximum continuous forward current for TLVG4200?

The TLVG4200 has an absolute maximum DC forward current of 30 mA at ambient temperatures ≤60 °C. Exceeding this value risks accelerated degradation and thermal runaway. At higher ambient temperatures, derating is required per Figure 1 in the datasheet; for example, at 85 °C ambient, the safe continuous current drops to approximately 20 mA. Always verify thermal margin using the 400 K/W junction-to-ambient resistance value when designing PCB copper area and airflow.

Does TLVG4200 require a current-limiting resistor in series?

Yes, TLVG4200 requires an external current-limiting resistor when driven from a fixed-voltage source. With a typical forward voltage of 2.4 V and maximum of 3.0 V at 20 mA, the resistor value must be calculated based on supply voltage and desired operating current - e.g., for 5 V supply and 20 mA target, a 100 Ω resistor provides appropriate bias. Constant-current drivers eliminate resistor dependency but must respect the 30 mA absolute maximum rating.

Can TLVG4200 be used in reverse-bias configurations?

No - TLVG4200 is not rated for sustained reverse-bias operation. Its absolute maximum reverse voltage is only 5 V, and the datasheet explicitly states that reverse conduction is suitable only for short-term applications (e.g., transient protection or multiplexed scanning). Continuous reverse bias will cause rapid degradation. For bidirectional signaling, use purpose-built dual-LED packages or discrete anti-parallel pairs with individual current limiting.

How does TLVG4200's luminous flux categorization affect ordering?

TLVG4200 is shipped in pre-binned luminous flux groups (e.g., Group R = 10–20 mlm) - each bag contains LEDs from only one brightness group. Single-group orders are not supported; distributors ship mixed-bag allocations to ensure availability. Engineers must design tolerance into optical systems to accommodate the full min–max flux range (10–30 mlm) rather than relying on tight binning unless specifying custom reels through Vishay's special-order process.

Is TLVG4200 RoHS-compliant and halogen-free?

Yes, TLVG4200 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (document #99912). The device uses lead-free matte tin-plated leads and halogen-free epoxy encapsulant. Full compliance documentation, including test reports and declarations of conformity, is available upon request from Aetrix Electronics or directly from Vishay's quality portal.
