Vishay Semiconductor Opto Division VLMW3201-GS08

Overview

VLMW3201-GS08 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-4 package, using InGaN/TAG-on-SiC technology, with minimum luminous intensity of 710 mcd at 30 mA, forward voltage 3.7–4.2 V, and ±60° viewing angle. It delivers enhanced thermal performance via optimized leadframe design, enabling higher drive current and doubled light output versus PLCC-2 predecessors - ideal for indicator backlighting and general illumination.

For engineers reviewing the VLMW3201-GS08 datasheet, VLMW3201-GS08 pinout, VLMW3201-GS08 application, or VLMW3201-GS08 equivalent, this page provides verified optical/electrical specs, thermal resistance (270 K/W), ESD Class 1 rating, JEDEC Level 2a preconditioning compliance, and real-world use context for reliable selection in lighting and display designs.

Technical Context

The VLMW3201-GS08 employs InGaN/TAG-on-SiC die architecture to achieve stable white emission with chromaticity coordinates centered at x=0.33, y=0.33 per CIE 1931. Its PLCC-4 leadframe is thermally optimized to reduce junction-to-ambient thermal resistance to 270 K/W when mounted on standard PCB pads.

It operates within -40 °C to +100 °C ambient range, supports DC forward current up to 30 mA (T_amb ≤ 65 °C), and exhibits temperature coefficients of -4 mV/K for forward voltage and -0.5 %/K for luminous intensity - enabling predictable performance across thermal environments.

FAQ

What is the minimum luminous intensity specification for VLMW3201-GS08?

The VLMW3201-GS08 has a guaranteed minimum luminous intensity of 710 mcd at 30 mA forward current and 25 °C ambient temperature. This value is measured with a 25 ms current pulse and ±11 % accuracy. The typical value is 900 mcd, and all units on a given reel fall within the V1 bin (710–900 mcd), ensuring consistent brightness across production lots.

Does VLMW3201-GS08 require special handling due to moisture sensitivity?

Yes, VLMW3201-GS08 is rated JEDEC Level 2a and must be stored in sealed dry bags until use. If exposed to ambient conditions exceeding 30 °C and 60 % RH, it requires baking before reflow: 192 h at 40 °C +5 °C/-0 °C and <5 % RH, or 96 h at 60 °C ±5 °C and <5 % RH. The EIA JESD22-A112 label on the packaging confirms this requirement.

What is the thermal resistance of VLMW3201-GS08, and how does it affect PCB layout?

VLMW3201-GS08 has a junction-to-ambient thermal resistance (R_thJA) of 270 K/W when mounted on the recommended PCB pad layout per Figure 6 in the datasheet. This value assumes a specific copper area and thickness; deviating from the recommended 2.05 × 1.95 mm pad with solder mask opening reduces thermal performance and may necessitate current derating below 30 mA.

Can VLMW3201-GS08 be used in reverse-bias configurations?

VLMW3201-GS08 is rated for a maximum reverse voltage of 5 V and can tolerate short-term reverse bias - such as during multiplexed display scanning - but is not designed for continuous reverse operation. Prolonged reverse bias beyond specifications risks degradation of the InGaN die and should be avoided in final designs.

What chromaticity coordinates does VLMW3201-GS08 meet, and how is color consistency ensured?

VLMW3201-GS08 is binned to chromaticity coordinates x = 0.33, y = 0.33 per CIE 1931, with tolerance ±0.01. Color consistency is maintained through automated spectral sorting during production, and each reel contains only one chromaticity group - eliminating mixed-bin shipments and ensuring uniform white point across assembled units.
