Product details
Overview
VLMO31J1K2-35-GS08 from Vishay Semiconductors is a soft orange SMD 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 backlighting and indicator applications requiring consistent visual output.
For engineers reviewing the VLMO31J1K2-35-GS08 datasheet, VLMO31J1K2-35-GS08 pinout, VLMO31J1K2-35-GS08 application, or VLMO31J1K2-35-GS08 equivalent, this device supports precise optical matching in telecommunication indicators, LCD backlighting, office equipment status displays, and low-power front-panel signaling where ±60° viewing angle and non-diffused lens coupling to light pipes are critical.
Technical Context
This soft orange LED uses GaAsP-on-GaP technology to achieve stable dominant wavelength (598–611 nm) and tight luminous intensity grouping (J1K2 bin). Its PLCC-2 package features a white thermoplastic body with clear epoxy-filled reflector and non-diffused lens optimized for directional coupling.
Rated for 20 mA DC forward current and 6 V reverse voltage, it operates across –40 °C to +100 °C ambient temperature with thermal resistance RthJA = 400 K/W on ≥16 mm² PCB pad. Preconditioned to JEDEC Level 2a and ESD-rated to 2 kV (HBM), it supports IR reflow, vapor phase, and wave soldering per CECC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4.5–11.2 mcd at 10 mA - defines visible brightness range within J1K2 bin for consistent panel appearance |
| Dominant wavelength | 598–611 nm - ensures soft orange chromaticity suitable for human-factor-compliant status indication |
| Forward voltage | 2.0–2.8 V at 20 mA - determines minimum drive rail and series resistor selection for constant-current biasing |
| Viewing angle | ±60° - enables wide but controlled illumination coverage without excessive lateral spill in compact UI layouts |
| Junction-to-ambient Rth | 400 K/W on ≥16 mm² pad - sets maximum allowable power dissipation (56 mW) under thermal derating constraints |
| ESD withstand | 2 kV HBM - confirms robustness during automated placement and board handling without special grounding protocols |
| Luminous intensity ratio | IVmax/IVmin ≤ 1.6 per reel - guarantees uniform brightness across full 1500-unit GS08 tape without mixing bins |
Pinout & Package
The VLMO31J1K2-35-GS08 is housed in a surface-mount PLCC-2 package with 2 terminals: anode and cathode. The package measures 3.5 mm × 2.8 mm × 1.75 mm (L × W × H), features a non-diffused lens, and uses a white thermoplastic body with internal reflector filled with clear epoxy.
| 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 breakdown (max VR = 6 V) |
| Cathode (K) | Negative LED terminal | Connected to ground or current sink; marking dot on package identifies cathode side per standard PLCC-2 orientation |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables efficient optical coupling to light pipes and edge-lit LCD backlights without scattering loss |
| Luminous intensity binning | J1K2 group ensures ≤1.6× intensity variation per reel-critical for uniform multi-LED panels |
| JEDEC Level 2a preconditioning | Validates moisture sensitivity level for safe lead-free reflow without popcorning or delamination |
| Low profile PLCC-2 | 1.75 mm height allows integration into space-constrained front panels and handheld device bezels |
| IR reflow compatible | Withstands peak 260 °C for ≤10 s per J-STD-020 - supports high-volume automated assembly |
