Product details
Overview
VLMTG1401-GS08 from Vishay Semiconductors is a true green surface-mount LED in 0603 package (1.6 mm × 0.8 mm × 0.55 mm), delivering 1400 mcd typical luminous intensity at 20 mA, with dominant wavelength 525 nm and forward voltage 2.80 V (typ). It serves as an indicator or backlight source in space-constrained, high-reliability portable electronics.
For engineers reviewing the VLMTG1401-GS08 datasheet, VLMTG1401-GS08 pinout, VLMTG1401-GS08 application, or VLMTG1401-GS08 equivalent, this page provides verified optical/electrical specs, JEDEC Level 2a moisture sensitivity handling, 146° viewing angle, InGaN technology validation, and tape-and-reel packaging details for production design-in.
Technical Context
This ChipLED uses InGaN semiconductor material to achieve stable true green emission at 525 nm (±10 nm), with spectral line half-width of 35 nm and peak wavelength at 518 nm. Its thermal resistance junction-to-ambient is 550 K/W when mounted on PCBs with pad area >5 mm².
The device operates across -40 °C to +80 °C ambient temperature, supports IR reflow soldering per J-STD-020C (peak 260 °C), and meets JEDEC Level 2a preconditioning requirements. Luminous intensity is measured under 25 ms pulse conditions with ±15% accuracy.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar true green LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMTG1400-GS08 | Lower VF bin (2.45–2.60 V vs. 2.60–3.05 V); same luminous intensity and wavelength specs | Better suited for low-voltage battery-powered systems where forward drop impacts runtime | Select VLMTG1400-GS08 if supply rail is ≤3.0 V and VF headroom is constrained |
| VLMTG1402-GS08 | Centered at 527 nm dominant wavelength (vs. 525 nm); identical intensity and VF ranges | Preferred where tighter color matching to 527 nm reference standards is required | Choose VLMTG1402-GS08 for applications demanding higher wavelength consistency in multi-LED arrays |
Compared with VLMTG1401-GS08, VLMTG1400-GS08 offers lower forward voltage for energy-sensitive designs, while VLMTG1402-GS08 provides a slightly longer dominant wavelength for improved color fidelity in calibrated optical systems - neither is pin-compatible replacement but share identical 0603 footprint and drive requirements.

FAQ
What is the exact dominant wavelength specification for VLMTG1401-GS08?
The VLMTG1401-GS08 has a dominant wavelength of 525 nm (typical), with minimum 515 nm and maximum 535 nm at 20 mA test current. This value is measured under pulsed 25 ms conditions with ±1 nm accuracy and defines its true green chromaticity for color-critical applications.
Does VLMTG1401-GS08 require baking before reflow soldering?
VLMTG1401-GS08 is shipped in JEDEC J-STD-033 Level 2a dry-packed reels. If the aluminum moisture barrier bag is opened and ambient conditions exceed <30 °C / 60% RH, baking is required before reflow if exposure exceeds 672 hours - per IPC/JEDEC J-STD-033 guidelines.
What is the recommended solder pad layout for VLMTG1401-GS08?
The recommended solder pad footprint for VLMTG1401-GS08 is 0.7 mm × 0.4 mm per terminal, with 0.8 mm center-to-center spacing. Pad dimensions align with the 0603 package outline (1.6 mm × 0.8 mm) and ensure reliable solder joint formation during IR reflow.
Can VLMTG1401-GS08 be driven continuously at 20 mA?
Yes - VLMTG1401-GS08 is rated for DC forward current of 20 mA at Tamb ≤ 25 °C. At higher ambient temperatures, derating applies: maximum IF drops to ~10 mA at 80 °C, as shown in Fig. 1 of the datasheet (Document No. 84393).
How does the viewing angle of VLMTG1401-GS08 affect optical design?
The VLMTG1401-GS08 has a ±73° angle of half intensity, resulting in a 146° total viewing angle. This wide dispersion reduces the need for secondary optics in indicator applications and ensures uniform brightness across angled viewing positions in compact UI layouts.
