Product details
Overview
VLMB41P1Q2-GS18 from Vishay Semiconductors is a blue surface-mount LED using InGaN-on-sapphire technology, housed in a PLCC-2 package with ±60° viewing angle, 90 mcd typical luminous intensity at 10 mA, and 469 nm typical dominant wavelength. It delivers stable optical output for automotive dashboard backlighting, office equipment indicators, and LCD symbol illumination under industrial ambient conditions.
For engineers reviewing the VLMB41P1Q2-GS18 datasheet, VLMB41P1Q2-GS18 pinout, VLMB41P1Q2-GS18 application, or VLMB41P1Q2-GS18 equivalent, this page provides verified electrical characteristics, AEC-Q101 qualification status, JEDEC level 2a moisture sensitivity handling, and real-world design constraints including thermal resistance (360 K/W), forward voltage range (3.2–4.2 V at 20 mA), and IR-reflow compatibility.
Technical Context
This device operates as a monochromatic blue light emitter optimized for visibility in indoor and automotive environments. Its PLCC-2 lead-frame-in-thermoplastic construction enables high thermal stability up to 110 °C junction temperature and supports wave, vapor-phase, and IR-reflow soldering per CECC 00802 and J-STD-020.
The VLMB41P1Q2-GS18 exhibits a negative temperature coefficient of forward voltage (−3 mV/K) and luminous intensity (−0.4 %/K), requiring thermal derating above 25 °C ambient. Its 2 kV ESD rating (JESD22-A114-B) and AEC-Q101 qualification confirm suitability for automotive-grade indicator applications where reliability under vibration and thermal cycling is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 45–112 mcd at 10 mA - defines visible brightness range for human-eye detection in low-ambient-light panels |
| Dominant wavelength | 462–476 nm (typ. 469 nm) - ensures consistent blue hue across production batches for color-matching UI elements |
| Forward voltage | 3.2–4.2 V at 20 mA - determines minimum supply headroom and series resistor sizing for constant-current drive |
| Viewing angle | ±60° half-intensity - specifies beam spread for uniform illumination of symbols or switch legends without hotspots |
| Junction temperature | 110 °C max - sets upper thermal limit for PCB layout and power dissipation planning (84 mW max at 25 °C) |
| Thermal resistance | 360 K/W (junction-to-ambient, mounted on >16 mm² pad) - quantifies required copper area for thermal management |
| ESD rating | 2 kV HBM (JESD22-A114-B) - informs ESD protection strategy during board assembly and field operation |
Pinout & Package
The VLMB41P1Q2-GS18 uses a 2-pin PLCC-2 surface-mount package with molded white thermoplastic body and internal clear epoxy lens. Pin identification follows standard PLCC-2 polarity: Cathode (pin 1) is marked by a notch or beveled corner; Anode (pin 2) is unmarked. Mounting requires 2.8 ± 0.15 mm pad spacing and soldermask-defined land pattern per Vishay drawing 20242.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (pin 2) | Positive terminal for forward bias | Connected to current-limiting resistor or constant-current source; must be at higher potential than cathode |
| Cathode (pin 1) | Negative terminal for forward bias | Typically tied to ground or low-side switch; polarity reversal risks permanent damage per datasheet note |
Key Features
| Feature | Design Value |
|---|---|
| InGaN-on-sapphire die technology | Enables high-efficiency blue emission with stable wavelength control and low degradation over 50,000-hour lifetime |
| AEC-Q101 qualification | Validates robustness for automotive interior lighting applications including dashboard switches and HVAC controls |
| JEDEC level 2a preconditioning | Confirms moisture sensitivity compliance for standard SMT reflow without baking when sealed bag is opened ≤672 h before assembly |
| EIA/ICE-standard PLCC-2 footprint | Ensures mechanical compatibility with automated pick-and-place equipment and industry-standard stencil designs |
| 8 mm tape reel (GS18 option) | Supplies 8,000 units per reel - supports high-volume manufacturing with minimal line changeovers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar blue SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LBT67C | Same PLCC-2 package, 470 nm dominant wavelength, 85 mcd @ 10 mA, but rated only to 85 °C junction temperature | Not AEC-Q101 qualified; limited to commercial-grade office and consumer equipment | Select when automotive qualification is unnecessary and lower thermal margin is acceptable |
| Vishay VLMB41P2Q2-GS08 | Identical package and wavelength, but higher luminous intensity bin (56–112 mcd vs. 45–112 mcd); same GS08 1,500-unit reel format | Suitable for applications requiring higher brightness without changing PCB layout or drive circuit | Choose when tighter brightness consistency is needed and smaller reel quantity suffices |
Compared with OSRAM LBT67C, VLMB41P1Q2-GS18 offers superior thermal capability (110 °C vs. 85 °C) and automotive qualification; compared with VLMB41P2Q2-GS08, it provides cost-optimized brightness for non-critical indicator roles while leveraging the larger 8,000-unit GS18 reel for production efficiency.

FAQ
What is the maximum continuous forward current for VLMB41P1Q2-GS18?
The VLMB41P1Q2-GS18 has a maximum DC forward current of 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated lumen depreciation and junction temperature violation beyond the 110 °C limit. Derating is required above 25 °C ambient per Figure 1 in the datasheet, and the device must never be reverse-biased as noted in the application notes.
Is VLMB41P1Q2-GS18 compatible with lead-free reflow soldering processes?
Yes, VLMB41P1Q2-GS18 is fully compatible with lead-free IR reflow soldering per J-STD-020, supporting peak package body temperatures up to 260 °C for ≤10 seconds. The recommended profile includes ramp-up ≤3 °C/s, soak at 150–200 °C for 60–120 s, and time above liquidus (217 °C) of 60–120 s - all validated in Figure 11 of the official Vishay document 81641.
Does VLMB41P1Q2-GS18 require baking before reflow if the moisture barrier bag is opened?
Yes - VLMB41P1Q2-GS18 is JEDEC level 2a moisture-sensitive. If the aluminum dry bag is opened and ambient conditions exceed 30 °C/60 % RH, the device must be mounted within 672 hours or baked prior to reflow. Acceptable bake conditions include 192 h at 40 °C +5 °C/-0 °C and <5 % RH, or 96 h at 60 °C ±5 °C and <5 % RH, as specified in the packaging section of document 81641.
What does the "P1Q2" suffix in VLMB41P1Q2-GS18 indicate?
The "P1Q2" suffix denotes the luminous intensity and dominant wavelength bins: "P" = 45–56 mcd intensity group, "1" = first sub-bin within P, "Q" = 71–90 mcd intensity group, "2" = second sub-bin within Q. However, per the Parts Table, VLMB41P1Q2-GS18 is shipped in the 45–112 mcd range (P1 + Q2 combined), with dominant wavelength binned into 466–472 nm (group 4), ensuring consistent optical performance per reel.
Can VLMB41P1Q2-GS18 be used in outdoor applications?
VLMB41P1Q2-GS18 is rated for operating temperatures from −40 °C to +100 °C and features a white thermoplastic package with UV-stable properties, but its optical specifications (e.g., luminous intensity, wavelength) are characterized only for indoor use. For outdoor message boards, additional environmental protection (e.g., conformal coating, secondary lens) and validation of long-term photometric stability under UV exposure are required beyond the datasheet scope.
