Product details
Overview
TLVP4202 from Vishay Semiconductors is a pure green backlighting LED in a 3 mm tinted non-diffused package, delivering 6.3–30 mln luminous flux at 15 mA, with dominant wavelength 555–565 nm, ±85° viewing angle, and forward voltage 2.4–3.0 V at 20 mA - optimized for uniform LCD panel and keyboard symbol illumination.
For engineers reviewing the TLVP4202 datasheet, TLVP4202 pinout, TLVP4202 application, or TLVP4202 equivalent, this device supports low-power, high-reliability backlighting where spectral purity, wide angular distribution, and stable luminous output across -40°C to +100°C ambient are critical selection criteria.
Technical Context
The TLVP4202 uses GaP-on-GaP semiconductor technology to achieve narrow-band pure green emission centered at 555 nm (peak) and 555–565 nm (dominant), enabling high color fidelity in display backlighting. Its ±85° half-intensity angle ensures broad spatial radiation coverage without secondary optics.
Rated for 30 mA DC forward current and 90 mW power dissipation, the device maintains low self-heating (RthJA = 400 K/W) and operates reliably from -40°C to +100°C ambient - supporting industrial-grade display interfaces requiring long-term photometric stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous flux | 6.3–30 mln at 15 mA - defines usable brightness range for segment-level backlighting without overdriving |
| Dominant wavelength | 555–565 nm - ensures consistent pure green chromaticity compliant with display color gamut requirements |
| Viewing angle | ±85° half-intensity - enables wide-area illumination from single-point source, reducing LED count per panel |
| Forward voltage | 2.4–3.0 V at 20 mA - compatible with standard 3.3 V or 5 V constant-current LED drivers |
| Max forward current | 30 mA continuous - sets thermal design limit for PCB trace width and heatsinking in compact layouts |
| Junction temperature | 100°C max - constrains ambient operating envelope and derating curves above 60°C |
| Thermal resistance | 400 K/W junction-to-ambient - informs thermal pad sizing and airflow requirements for sustained operation |
Pinout & Package
TLVP4202 is housed in a standard Ø3 mm tinted non-diffused radial-leaded package (drawing No. 6.544-5268.01-4), with cathode-indicated lead and 2.54 mm lead pitch. Package dimensions: 4.6 ± 0.3 mm height, Ø3.4 ± 0.15 mm body, 33.08 ± 0.5 mm lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive supply connection | Must be driven by constant-current source; polarity reversal risks damage per note (1) |
| Cathode (shorter/flat-side lead) | Ground reference | Identified by flat edge on package body; required for correct orientation in automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Pure green emission | 555–565 nm dominant wavelength enables accurate color matching in RGB backlight systems |
| Wide viewing angle | ±85° half-intensity distribution eliminates hotspots and supports uniform illumination of irregular surfaces |
| Tinted clear package | Enhances contrast ratio in daylight-readable displays by suppressing ambient light scatter |
| Low power dissipation | 90 mW max allows dense LED arrays without thermal throttling in sealed enclosures |
| Rugged mechanical design | Radial leads with 2.54 mm pitch support wave soldering and manual rework without lead fracture |
Applications

Use Value: Stable luminous flux over -40°C to +100°C ensures readability across environmental test chambers and field use. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar pure green LED backlighting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLVP4201 | Higher luminous flux (16–30 mln vs. 6.3–30 mln); same wavelength and package | Better suited for high-brightness segments where visual impact outweighs power budget | Select TLVP4201 when >15 mln minimum output is required; TLVP4202 offers tighter low-end flux control |
| TLVG4200 | Green (not pure green); dominant wavelength 562–575 nm; lower typical flux (10–30 mln) | Acceptable for non-color-critical indicators but lacks chromatic precision for calibrated displays | Choose TLVG4200 only if spectral tolerance >10 nm is acceptable; TLVP4202 ensures strict 555–565 nm compliance |
Compared with TLVP4201 and TLVG4200, TLVP4202 provides the most precise pure green chromaticity and lowest minimum luminous flux bin (Q group: 6.3–12.5 mln), making it optimal for applications demanding both color fidelity and dimmable low-light performance.

FAQ
What is the dominant wavelength range specified for TLVP4202?
The TLVP4202 has a dominant wavelength range of 555–565 nm, measured at 10 mA forward current. This narrow band defines its "pure green" classification and distinguishes it from broader green variants like TLVG4200. The specification is confirmed in the Optical and Electrical Characteristics table for TLVP420. series on page 3 of Vishay document 83057, ensuring consistent color rendering in display backlighting applications where TLVP4202 is deployed.
What luminous flux bin does TLVP4202 fall into according to Vishay's classification?
TLVP4202 is categorized in the Q luminous flux group (6.3–12.5 mln), as defined in the Luminous Flux Classification table on page 3 of Vishay document 83057. This binning ensures predictable low-end brightness for dimming-critical applications, and each bag contains only Q-group units - no mixing with other flux groups occurs per Vishay's shipping policy.
Can TLVP4202 be driven with reverse voltage?
Per Note (1) in the Vishay datasheet, short-term reverse voltage application is permitted for TLVP4202, but absolute maximum reverse voltage is limited to 5 V. Sustained reverse bias is not recommended, as it may degrade junction integrity. Designers should implement polarity protection or ensure driver circuitry prevents accidental reverse connection during power sequencing or fault conditions involving TLVP4202.
What is the maximum continuous forward current rating for TLVP4202?
The TLVP4202 is rated for 30 mA DC forward current at ambient temperatures ≤60°C, as stated in the Absolute Maximum Ratings table on page 1 of Vishay document 83057. Above 60°C, current must be derated linearly per Fig. 1 (Forward Current vs. Ambient Temperature), reaching zero at 100°C. This rating directly governs trace width, copper area, and thermal management design for any PCB using TLVP4202.
How does the TLVP4202 package differ from standard 3 mm LEDs?
The TLVP4202 uses a Ø3 mm tinted non-diffused package with specific mechanical dimensions: 4.6 ± 0.3 mm height, Ø3.4 ± 0.15 mm body, and 2.54 mm lead pitch (drawing No. 6.544-5268.01-4). Unlike standard diffused 3 mm LEDs, its tinted clear lens enhances contrast in bright environments and supports precise angular control - critical for backlighting applications where TLVP4202 is specified.
