Product details
Overview
VLMY31J1K2-GS08 from Vishay Semiconductors is a yellow surface-mount LED in PLCC-2 package, with dominant wavelength 581–594 nm, luminous intensity 4.5–11.2 mcd at 10 mA, and forward voltage 2.1–2.8 V at 20 mA - designed for indicator and LCD backlighting in telecommunication and office equipment.
For engineers reviewing the VLMY31J1K2-GS08 datasheet, VLMY31J1K2-GS08 pinout, VLMY31J1K2-GS08 application, or VLMY31J1K2-GS08 equivalent, key selection criteria include narrow luminous intensity binning (J1/K2 group), ±60° viewing angle, GaAsP-on-GaP technology, IR-reflow compatibility, and ESD rating of 2 kV per JESD22-A114-B.
Technical Context
This device uses GaAsP-on-GaP semiconductor technology to emit yellow light with dominant wavelength centered at 588 nm and peak wavelength at 590 nm. Its optical output is characterized by non-diffused lens geometry, enabling efficient coupling to light pipes and uniform flat backlighting.
The PLCC-2 package features a white thermoplastic body with embedded lead frame and clear epoxy-filled reflector cavity. Thermal resistance junction-to-ambient is 400 K/W when mounted on a PCB pad >16 mm², supporting operation from −40 °C to +100 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Yellow - precise chromaticity for status indication and symbol illumination |
| Luminous intensity | 4.5–11.2 mcd at 10 mA - binned to J1/K2 group for consistent brightness across reels |
| Dominant wavelength | 581–594 nm - tightly controlled for color-matching in multi-LED arrays |
| Viewing angle | ±60° - wide dispersion suitable for panel-level backlighting and front-panel indicators |
| Forward voltage | 2.1–2.8 V at 20 mA - enables low-power drive with standard 3.3 V or 5 V logic-compatible current limiting |
| ESD withstand | 2 kV HBM - meets industrial handling requirements without additional protection circuitry |
| Absolute max forward current | 20 mA continuous - defines safe DC operating limit for long-life reliability |
Pinout & Package
PLCC-2 package: 2-terminal surface-mount device with cathode/anode configuration; dimensions 3.5 mm × 2.8 mm × 1.75 mm (L × W × H); recommended footprint includes 2.6 mm × 1.6 mm solder pads with 1.2 mm spacing and soldermask-defined land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source; polarity must be observed to avoid reverse conduction beyond 6 V |
| Cathode (K) | Negative terminal | Connected to ground or current sink; marking dot on package identifies cathode side |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity ratio ≤ 1.6 | Ensures minimal brightness variation within a single tape reel - critical for consistent visual appearance in production assemblies |
| Non-diffused lens | Maximizes directional light output for efficient coupling into light guides and edge-lit LCD backlights |
| JEDEC Level 2a preconditioning | Validates moisture sensitivity compliance for Pb-free reflow - eliminates need for baking prior to assembly if handled within 672 h |
| IR-reflow, vapor-phase & wave-solder compatible | Supports high-volume SMT manufacturing without thermal damage up to 260 °C peak package temperature |
| Low profile (1.75 mm height) | Enables ultra-thin front-panel designs and tight clearance in stacked PCB assemblies |
Applications
| Telecom Indicator | A/V Equipment Backlight |
|---|---|
Use Scenario: Status indication on telephone handsets, fax machines, and VoIP endpoints requiring visible, non-distracting yellow light. IC Role / Device Role / Timing Role: Light-emitting diode providing human-readable operational feedback.

IC Role / Device Role / Timing Role: Surface-mount visual indicator aligned with polycarbonate overlays. Use Value: PLCC-2 package withstands automated placement and reflow; ESD rating of 2 kV prevents field failures during handling and service. |
Use Scenario: Edge-lit backlight for monochrome or segmented LCDs in test instruments, industrial HMIs, and point-of-sale terminals. IC Role / Device Role / Timing Role: Primary light source coupled via light guide to achieve uniform panel illumination. Use Value: Dominant wavelength 588 nm provides high photopic luminance; low thermal resistance supports stable output over extended operating life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LYT670-J1K2 | Identical luminous intensity binning (J1/K2) and dominant wavelength range; same PLCC-2 footprint and optical characteristics | Direct cross-reference per Vishay's official crossing table; validated for identical indicator and backlight use cases | Select when OSRAM sourcing preference or dual-source strategy applies; no layout or drive circuit changes required |
| VLMY31K1L2-GS08 | Higher luminous intensity (7.1–18 mcd) and different binning (K1/L2); otherwise identical package, wavelength, and electrical specs | Suitable where higher brightness is needed without changing board layout or optics - e.g., outdoor-visible panels or high-ambient-light environments | Choose VLMY31K1L2-GS08 only if increased output justifies tighter bin control trade-offs; same thermal and soldering profile |
Compared with VLMY31J1K2-GS08, the OSRAM LYT670-J1K2 offers full functional and mechanical equivalence, while VLMY31K1L2-GS08 provides higher intensity within the same family - enabling brightness scaling without redesigning optics or PCB layout.

FAQ
What is the luminous intensity range of the VLMY31J1K2-GS08 at 10 mA?
The VLMY31J1K2-GS08 has a luminous intensity range of 4.5–11.2 mcd at 10 mA, binned specifically to the J1/K2 group per Vishay's classification table - ensuring consistent brightness within each 1500-piece GS08 tape reel. This binning minimizes visible variation in multi-LED assemblies and supports reliable visual signaling in production units.
Does the VLMY31J1K2-GS08 support Pb-free reflow soldering?
Yes, the VLMY31J1K2-GS08 is qualified for Pb-free reflow soldering per J-STD-020, with a maximum peak package temperature of 260 °C for up to 10 seconds. Its PLCC-2 package and internal construction are fully compatible with standard IR reflow, vapor-phase, and wave-solder processes - verified under JEDEC Level 2a preconditioning.
What is the dominant wavelength specification for the VLMY31J1K2-GS08?
The VLMY31J1K2-GS08 has a dominant wavelength range of 581–594 nm, with a typical value of 588 nm and peak wavelength at 590 nm. This yellow emission is achieved using GaAsP-on-GaP technology and is tightly binned to ensure color consistency across production lots - essential for applications requiring matched chromaticity.
How is the VLMY31J1K2-GS08 packaged for automated assembly?
The VLMY31J1K2-GS08 is supplied in an antistatic 8 mm blister tape (GS08 option), containing 1500 pieces per reel. The tape complies with DIN IEC 40 (CO) 564 and supports high-speed pick-and-place equipment. Polarity is marked with a dot on the cathode side, and the PLCC-2 footprint is optimized for standard SMT placement accuracy.
What is the maximum continuous forward current rating for the VLMY31J1K2-GS08?
The VLMY31J1K2-GS08 has a maximum DC forward current rating of 20 mA at ambient temperatures ≤60 °C. Exceeding this limit risks accelerated degradation and reduced lifetime. For pulsed operation, surge current up to 340 mA is allowed for ≤10 μs pulses - useful in multiplexed display drivers where duty cycle limits average power dissipation.
