Product details
Overview
VLMO31J1K2-GS08 from Vishay Semiconductors is a surface-mount soft orange LED in PLCC-2 package, with luminous intensity of 4.5–11.2 mcd at 10 mA, dominant wavelength 598–611 nm, and forward voltage 2.0–2.8 V at 20 mA. It delivers narrow brightness and color binning (IVmax/IVmin ≤ 1.6 per reel) for consistent backlighting and indicator use in telecom and office equipment.
For engineers reviewing the VLMO31J1K2-GS08 datasheet, VLMO31J1K2-GS08 pinout, VLMO31J1K2-GS08 application, or VLMO31J1K2-GS08 equivalent, this page provides verified optical/electrical specs, PLCC-2 terminal mapping, SMD assembly compatibility (JEDEC level 2a, IR reflow), and validated alternative LEDs for indicator and backlight designs requiring ±60° viewing angle and GaAsP-on-GaP technology.
Technical Context
This soft orange LED uses GaAsP-on-GaP semiconductor technology to achieve stable dominant wavelength (605 nm typ.) and low forward voltage (2.0–2.8 V). Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and non-diffused optics optimized for light-pipe coupling and flat backlighting.
Rated for 20 mA DC forward current and 100 °C junction temperature, it supports JEDEC level 2a preconditioning and withstands 2 kV ESD (HBM). Thermal resistance is 400 K/W when mounted on ≥16 mm² PCB pad, enabling reliable operation across –40 to +100 °C ambient range.
Key Specifications

Pinout & Package
The VLMO31J1K2-GS08 is housed in a standard SMD PLCC-2 package with 2 terminals: anode and cathode. The package has a low-profile, non-diffused lens and white thermoplastic reflector filled with clear epoxy. Dimensions are 3.5 ± 0.2 mm × 2.8 ± 0.15 mm × 1.75 ± 0.1 mm (L × W × H), with recommended footprint per Vishay drawing 6.541-5067.01-4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source or higher potential; polarity must be observed to avoid reverse conduction |
| Cathode (K) | Negative LED terminal | Connected to ground or current sink; marked by notch on package edge per PLCC-2 standard |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | IVmax/IVmin ≤ 1.6 per reel - ensures consistent brightness across production units without manual sorting |
| Non-diffused lens | Enables efficient coupling into light pipes and edge-lit LCD backlights with minimal optical loss |
| JEDEC level 2a compliance | Qualified for lead-free reflow (260 °C peak, ≤120 s) - supports high-yield automated SMT assembly |
| Low profile PLCC-2 | Height ≤1.75 mm - allows integration into space-constrained front panels and compact consumer devices |
| ESD robustness | 2 kV HBM rating - reduces risk of field failure due to handling or system-level transients |
