Product details
Overview
VLMK334BACB-GS08 from Vishay Semiconductors is an orange-red power SMD LED in PLCC-2 package, rated for 70 mA DC forward current, with dominant wavelength 611–622 nm, luminous intensity 1800–4500 mcd at 50 mA, and forward voltage 1.9–2.8 V - used in dashboard illumination and traffic signal indicators where high-brightness visible-light output and AEC-Q101 qualification are required.
For engineers reviewing the VLMK334BACB-GS08 datasheet, VLMK334BACB-GS08 pinout, VLMK334BACB-GS08 application, or VLMK334BACB-GS08 equivalent, key selection criteria include its ±60° viewing angle, 300 K/W thermal resistance, AlInGaP-on-Si technology, JEDEC level 2a preconditioning compliance, and compatibility with reflow, vapor-phase, and wave soldering processes.
Technical Context
The VLMK334BACB-GS08 uses AlInGaP-on-Si die technology to deliver stable orange-red emission with dominant wavelength centered at 616 nm (typ.) and spectral bandwidth of 18 nm at 50% relative intensity. Its PLCC-2 thermoplastic package features a white reflector cavity filled with clear epoxy, enabling high optical efficiency and consistent color binning.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and supports operation from −40 °C to +100 °C ambient. Thermal resistance junction-to-ambient is 300 K/W when mounted on a PCB pad >16 mm², and ESD withstand voltage reaches 2 kV per JESD22-A114-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current | 70 mA max DC - enables high-brightness operation without derating below 65 °C ambient. |
| Dominant wavelength | 611–622 nm - defines precise orange-red chromaticity suitable for regulatory-compliant signaling. |
| Luminous intensity | 1800–4500 mcd at 50 mA - provides wide brightness binning for consistent visual performance across production reels. |
| Forward voltage | 1.9–2.8 V at 50 mA - supports low-voltage drive architectures while maintaining margin for thermal drift. |
| Viewing angle | ±60° - delivers wide, uniform illumination ideal for panel indicators and signage applications. |
| Thermal resistance | 300 K/W - determines required PCB copper area (>16 mm²) to maintain junction temperature ≤125 °C. |
| ESD rating | 2 kV HBM - ensures robust handling during automated assembly and field service without added protection circuitry. |
Pinout & Package
Package: PLCC-2 surface-mount package with white thermoplastic body, embedded lead frame, and clear epoxy-filled reflector cavity. Dimensions: 3.5 ± 0.2 mm × 2.8 ± 0.15 mm × 1.75 ± 0.1 mm (L × W × H), with 2.2 mm center-to-center pin spacing and 0.9 mm pin width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source; polarity must be observed to avoid reverse breakdown (max VR = 5 V short-term). |
| Cathode (K) | Negative terminal | Connected to ground or current sink; reverse leakage ≤10 μA at 5 V ensures low standby power loss. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics use, including dashboard and exterior lighting systems requiring long-term reliability under thermal cycling and humidity exposure. |
| JEDEC level 2a preconditioning | Enables safe reflow soldering without moisture-induced popcorning; dry-packaged in antistatic blister tape with desiccant and humidity indicator. |
| Reflow/wave solder compatible | Rated for peak reflow temperatures up to 260 °C (J-STD-020) and double-wave soldering per CECC 00802 - eliminates need for special process adjustments. |
| Color and intensity binning | Luminous intensity ratio IVmax/IVmin ≤ 1.6 per reel; dominant wavelength grouped into six defined bins - ensures visual consistency across assemblies. |
| High thermal resistance tolerance | 300 K/W RthJA allows direct thermal design using standard FR-4 PCBs without heatsinks in moderate-power applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar orange-red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LA T67F-U2AB-24-1 (OSRAM) | Same dominant wavelength range (611–622 nm), but lower max luminous intensity (3200 mcd vs. 4500 mcd); uses InGaN/AlInGaP hybrid structure. | Qualified to AEC-Q102 (optoelectronics) rather than AEC-Q101; not rated for 70 mA continuous drive. | Select when legacy OSRAM supply chain alignment is required and peak intensity demand is ≤3200 mcd. |
| VLMR334BACB-GS08 (Vishay) | Red variant (619–631 nm), identical package, drive capability, and thermal specs; 2200 mcd typ. intensity at 50 mA. | Better suited for applications requiring strict red chromaticity (e.g., brake lights), not orange-red signaling or warm-tone interior lighting. | Choose for color-critical red applications where VLMK334BACB-GS08's orange-red shift would violate specification. |
Compared with LA T67F-U2AB-24-1, VLMK334BACB-GS08 delivers higher luminous intensity and broader automotive qualification; versus VLMR334BACB-GS08, it offers distinct orange-red chromaticity essential for non-braking signaling functions where spectral separation from red is mandated.

FAQ
What is the maximum continuous forward current rating for VLMK334BACB-GS08?
The VLMK334BACB-GS08 has a maximum DC forward current rating of 70 mA when ambient temperature is ≤65 °C. At higher ambient temperatures, derating is required per Figure 1 in the datasheet. This rating reflects its enhanced chip size over the earlier VLM.31.. series and enables higher luminous output without thermal runaway.
Is VLMK334BACB-GS08 qualified for automotive applications?
Yes, VLMK334BACB-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity bias, mechanical shock, and ESD required for automotive electronic components. It is explicitly intended for dashboard illumination, traffic signals, and other vehicle-mounted visible-light applications.
What does the "BACB" suffix indicate in VLMK334BACB-GS08?
The "BACB" suffix denotes specific binning: "BA" indicates luminous intensity group (1800–2240 mcd), and "CB" indicates dominant wavelength group (614–622 nm). This ensures consistent optical performance within each reel - no mixing of intensity or wavelength bins occurs per packaging unit.
Can VLMK334BACB-GS08 be soldered using standard reflow profiles?
Yes, VLMK334BACB-GS08 is compatible with lead-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. Its PLCC-2 package is also qualified for vapor-phase and wave soldering per CECC 00802, with no special prebake required if stored per JEDEC level 2a guidelines.
What is the thermal resistance junction-to-ambient for VLMK334BACB-GS08?
The thermal resistance junction-to-ambient (RthJA) for VLMK334BACB-GS08 is 300 K/W when mounted on a PCB with a minimum pad area of 16 mm². This value is measured under standardized test conditions and guides thermal layout design to keep junction temperature ≤125 °C under worst-case drive and ambient conditions.
