Product details
Overview
VLMK33S1T1-GS08 from Vishay Semiconductors is an amber surface-mount power LED in PLCC-2 package, rated for 50 mA DC forward current, with luminous intensity of 180–355 mcd at 20 mA, dominant wavelength 611–622 nm, and ±60° viewing angle. It serves as a high-brightness indicator or backlight source in automotive interior lighting and industrial control panels.
For engineers reviewing the VLMK33S1T1-GS08 datasheet, VLMK33S1T1-GS08 pinout, VLMK33S1T1-GS08 application, or VLMK33S1T1-GS08 equivalent, this page delivers verified optical, electrical, thermal, and packaging data - including AEC-Q101 qualification, JEDEC level 2a preconditioning, and IR reflow compatibility - to support reliability-critical LED selection and layout validation.
Technical Context
The VLMK33S1T1-GS08 uses AlInGaP on GaAs technology to deliver amber light with peak wavelength at 624 nm and spectral bandwidth of 18 nm at 50% relative intensity. Its PLCC-2 package features a white thermoplastic body with clear epoxy-filled reflector cavity, enabling high reflectivity and directional emission.
Thermal resistance junction-to-ambient is 400 K/W when mounted on a PCB pad >16 mm², supporting stable operation up to 125 °C junction temperature. Absolute maximum ratings include 5 V reverse voltage, 130 mW power dissipation, and -40 to +100 °C operating/storage temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 180–355 mcd at 20 mA - defines brightness range for visibility under ambient lighting in indicator applications |
| Dominant wavelength | 611–622 nm - specifies amber color binning for consistent human-perceived hue across production lots |
| Forward voltage | 1.9–2.5 V at 20 mA - determines minimum supply headroom and series resistor sizing in constant-current drive circuits |
| Viewing angle | ±60° - sets beam spread for uniform illumination over defined panel area without secondary optics |
| Thermal resistance | 400 K/W - quantifies self-heating impact; requires ≥16 mm² copper pad for safe 50 mA continuous operation |
| ESD withstand | 2 kV HBM per JESD22-A114-B - confirms robustness against handling discharge during SMT assembly |
| AEC-Q101 qualified | Validated for automotive-grade reliability - supports use in dashboard indicators and exterior signaling where qualification is mandatory |
Pinout & Package
PLCC-2 package (equivalent to size B tantalum capacitor) with 2 terminals: anode and cathode. Molded white thermoplastic body with integrated reflector cavity filled with clear epoxy; lead frame embedded for mechanical stability and thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to constant-current source or series resistor; polarity must be observed to avoid reverse breakdown |
| Cathode (K) | Negative terminal | Typically tied to ground or low-side switch; reverse voltage rating limited to 5 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive environments - enables use in OEM dashboard and cabin lighting without additional qualification effort |
| PLCC-2 SMD package | Standardized footprint compatible with automated pick-and-place and IR reflow (J-STD-020), vapor phase, and wave soldering |
| 50 mA DC forward current rating | Supports higher brightness than legacy 30 mA LEDs - allows design margin for aging or temperature derating |
| ±60° viewing angle | Enables wide-area illumination from single device - reduces component count in backlight arrays for segmented displays |
| JEDEC level 2a preconditioning | Ensures moisture sensitivity compliance - eliminates need for baking before reflow in standard factory environments |
Applications
| Automotive Dashboard Indicators | Industrial Control Panel Backlighting |
|---|---|
Use Scenario: Illuminating status symbols (e.g., "Check Engine", gear position) on curved instrument cluster overlays. IC Role / Device Role / Timing Role: Amber light emitter providing human-visible feedback under variable ambient lighting and viewing angles. Use Value: ±60° viewing angle ensures legibility across driver's seating positions; AEC-Q101 qualification guarantees long-term reliability in thermal cycling environments. |
Use Scenario: Edge-lit backlighting for membrane switch legends on factory HMIs exposed to dust, vibration, and wide temperature swings. IC Role / Device Role / Timing Role: High-intensity amber LED delivering consistent luminance without phosphor degradation. Use Value: 180–355 mcd output at 20 mA enables low-power drive while maintaining visibility; PLCC-2 package resists mechanical stress from panel flexing. |
| Consumer Audio/Video Equipment Indicators | Emergency Exit Sign Auxiliary Lighting |
Use Scenario: Power-on and mode-status indication on AV receivers and streaming devices with dark front-panel aesthetics. IC Role / Device Role / Timing Role: Visual status element requiring precise amber hue matching brand identity and low EMI emission. Use Value: 611–622 nm dominant wavelength ensures color consistency across batches; clear epoxy lens minimizes yellowing over time. |
Use Scenario: Redundant illumination source in battery-backed exit signs where incandescent lamp replacement is impractical. IC Role / Device Role / Timing Role: Solid-state alternative to filament lamps offering longer lifetime and shock resistance. Use Value: 50 mA rating and 130 mW power dissipation allow sustained operation during extended emergency cycles; -40 to +100 °C rating covers indoor/outdoor mounting conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar amber LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LAT676-S1T1 | Identical luminous intensity (180–355 mcd) and wavelength (611–622 nm); same PLCC-2 package but different tape/reel coding (LT instead of GS) | Qualified to AEC-Q102 (optoelectronics-specific) rather than AEC-Q101; identical automotive suitability but different test scope | Select LAT676-S1T1 if OSRAM supply chain integration or AEC-Q102 documentation alignment is required |
| Vishay VLMK33S1T1-GS18 | Identical optical/electrical specs; differs only in reel quantity (8000 pcs vs. 1500 pcs) and tape option (GS18 vs. GS08) | No functional difference - GS18 is preferred for high-volume production due to larger reel size and lower handling cost per unit | Select VLMK33S1T1-GS18 for volume procurement where reel change frequency and line efficiency are critical |
Compared with VLMK33S1T1-GS08, LAT676-S1T1 offers equivalent photometric performance with alternate qualification coverage, while VLMK33S1T1-GS18 provides identical functionality in a higher-density reel format - both preserve the same thermal, optical, and mechanical interface for drop-in manufacturing continuity.
