Product details
Overview
VLMS31J1K2-GS08 from Vishay Semiconductors is a high-intensity red surface-mount LED in PLCC-2 package, featuring 4.5–11.2 mcd luminous intensity at 10 mA, 624–638 nm dominant wavelength, ±60° viewing angle, and 1.9–2.6 V forward voltage at 20 mA. It serves as an indicator or backlight in compact consumer and office electronics.
For engineers reviewing the VLMS31J1K2-GS08 datasheet, VLMS31J1K2-GS08 pinout, VLMS31J1K2-GS08 application, or VLMS31J1K2-GS08 equivalent, key selection factors include luminous intensity binning (J1K2 group), GaAsP-on-GaP chip technology, PLCC-2 mechanical compatibility, IR reflow soldering compliance, and ESD robustness up to 2 kV.
Technical Context
This red SMD LED uses GaAsP-on-GaP semiconductor technology to deliver stable visible emission with dominant wavelength centered at 630 nm and peak wavelength at 643 nm. Its non-diffused lens enables efficient coupling to light pipes and uniform flat backlighting for symbols and LCDs.
The device operates within -40 °C to +100 °C ambient range, supports 20 mA DC forward current, and exhibits 400 K/W thermal resistance junction-to-ambient when mounted on ≥16 mm² PCB pad. Reverse voltage rating is 6 V, and junction capacitance is 15 pF at 0 V and 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4.5–11.2 mcd at 10 mA - defines brightness range for visual indication under standard drive |
| Dominant wavelength | 624–638 nm - specifies red spectral output compatible with human eye sensitivity and color coding |
| Forward voltage | 1.9–2.6 V at 20 mA - determines minimum supply headroom and power dissipation (≤80 mW) |
| Viewing angle | ±60° - provides wide, symmetric angular distribution suitable for front-panel indicators |
| ESD withstand | 2 kV HBM - ensures handling robustness during automated placement and board assembly |
| Junction temperature | 100 °C max - sets thermal derating limit for continuous operation in enclosed environments |
| Thermal resistance | 400 K/W - quantifies heat transfer efficiency from die to ambient on standard PCB layout |
Pinout & Package
VLMS31J1K2-GS08 uses a 2-pin PLCC-2 surface-mount package with molded white thermoplastic body and clear epoxy-filled reflector. Dimensions: 3.5 mm × 2.8 mm × 1.9 mm (L × W × H), with 2.2 mm lead spacing and 0.8 mm nominal thickness. Recommended footprint includes 2.6 mm × 1.6 mm solder pads with soldermask-defined openings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source; polarity must be observed to avoid reverse conduction beyond 6 V |
| Cathode (K) | Negative LED terminal | Connected to ground or current sink; identifies cathode via notch on package top surface |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | J1K2 group (4.5–11.2 mcd) ensures consistent brightness across reels without mixing |
| Non-diffused lens | Enables precise optical coupling to light guides and uniform edge-lit backlight panels |
| Reflow-compatible packaging | Qualified for Pb-free IR reflow (peak 260 °C, ≤10 s) per J-STD-020 and CECC 00802 |
| Low profile form factor | 1.9 mm height allows integration into space-constrained front panels and slim displays |
| ESD protection | 2 kV HBM rating reduces risk of damage during automated pick-and-place and handling |
Applications
| Telecom Indicator | Audio/Video Backlight |
|---|---|
Use Scenario: Status indication on telephone handsets and fax machine control panels. IC Role / Device Role / Timing Role: Visual emitter providing user feedback for line status, message waiting, or dial tone detection. Use Value: High luminous intensity (≥4.5 mcd) ensures visibility in ambient light; ±60° viewing angle covers typical operator viewing zone. |
Use Scenario: Backlighting for volume knobs, input selectors, and display overlays in AV receivers and DVD players. IC Role / Device Role / Timing Role: Constant-current driven red light source for panel illumination. Use Value: Non-diffused lens couples efficiently to molded light pipes; low 20 mA drive minimizes power draw in always-on features. |
| Office Equipment Symbol | LCD Flat Backlight |
Use Scenario: Power-on, paper-jam, or network-connect indicators on printers, scanners, and multifunction devices. IC Role / Device Role / Timing Role: Discrete optical indicator integrated into PCB-mounted front bezel assemblies. Use Value: PLCC-2 package supports high-speed placement; luminous intensity ratio ≤1.6 ensures uniform appearance across units. |
Use Scenario: Edge-lit backlight for character LCDs, membrane switch legends, and function key labels. IC Role / Device Role / Timing Role: Primary red light source positioned at LCD perimeter with light-guide interface. Use Value: 630 nm dominant wavelength matches photopic response; ±60° beam pattern delivers even illumination across narrow-width light guides. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LST670-J1K2 | OSRAM equivalent with identical luminous intensity bin (J1K2), same PLCC-2 package, and matching 624–638 nm wavelength range | No functional deviation; validated for same telecom and office equipment use cases | Select when dual-sourcing or OSRAM-designated BOMs require direct cross-reference |
| VLMS31J1L2-GS08 | Same package and technology but higher luminous intensity bin (J1L2: 4.5–18 mcd), wider output range | Suitable where higher brightness margin is needed, but requires verification of optical saturation in existing light-pipe geometry | Choose only if design tolerates >11.2 mcd upper bound; not drop-in due to intensity variance |
Compared with VLMS31J1K2-GS08, LST670-J1K2 offers identical optical and mechanical specs for seamless second-source deployment, while VLMS31J1L2-GS08 provides higher maximum intensity at the cost of reduced bin consistency-requiring optical redesign validation.
