Product details
Overview
VLMD31M2P1-GS08 from Vishay Semiconductors is a red surface-mount LED in PLCC-2 package, GaAlAs-on-GaAs technology, with luminous intensity of 22.4–56 mcd at 10 mA, dominant wavelength 648 nm, and ±60° viewing angle-designed for automotive dashboard backlighting and indicator applications requiring tight brightness binning.
For engineers reviewing the VLMD31M2P1-GS08 datasheet, VLMD31M2P1-GS08 pinout, VLMD31M2P1-GS08 application, or VLMD31M2P1-GS08 equivalent, this device supports IR reflow soldering per J-STD-020, meets AEC-Q101 qualification, and delivers narrow-luminance-ratio (IVmax/IVmin ≤ 1.6) within reel packaging for consistent optical performance in production-grade indicator systems.
Technical Context
This SMD LED uses GaAlAs on GaAs semiconductor material to achieve high-efficiency red emission at 648 nm dominant wavelength with low forward voltage (1.8–2.2 V at 20 mA) and thermal stability (TCλd = +0.05 nm/K, TCVF = −1.8 mV/K). Its PLCC-2 package features a white thermoplastic lead frame and clear epoxy lens for directional light output.
Optical performance is characterized under pulsed conditions (25 ms pulse width, ±11% measurement accuracy), with angular intensity distribution peaking at 0° and falling to 50% at ±60°. The device operates across −40 °C to +100 °C ambient temperature and supports surge forward current up to 0.5 A for transient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 22.4–56 mcd at 10 mA - enables high-visibility indicators without excessive drive current |
| Dominant wavelength | 648 nm - standardized red color for automotive and telecom signaling compliance |
| Viewing angle | ±60° - provides wide, uniform illumination for backlighting flat panels and symbols |
| Forward voltage | 1.8–2.2 V at 20 mA - compatible with 3.3 V and 5 V logic-supplied LED drivers |
| Reverse voltage | 6 V - sufficient margin for transient protection in low-voltage indicator circuits |
| Junction capacitance | 7 pF at 0 V, 1 MHz - negligible impact on switching speed in DC indicator use |
| Thermal resistance | 400 K/W (junction-to-ambient, mounted on >16 mm² pad) - requires thermal pad design for sustained 30 mA operation |
Pinout & Package
VLMD31M2P1-GS08 is housed in a standard SMD PLCC-2 package (4.1 × 3.9 mm footprint, 1.6 mm height) with non-diffused lens and white thermoplastic reflector. Anode and cathode terminals are located on opposite sides of the rectangular body, aligned with industry-standard PLCC-2 polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal | Connected to current source or driver high-side; must be biased ≥1.8 V above cathode for conduction |
| Cathode | Negative terminal | Connected to ground or driver low-side; polarity reversal is permissible only for short-term testing (per Note 1) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
| Luminous intensity ratio ≤1.6 | Ensures consistent brightness across all units on a single tape reel-critical for uniform backlight appearance |
| JEDEC Level 2a preconditioning | Enables safe IR reflow processing without moisture-induced popcorning (max 672 h dry storage after opening) |
| Non-diffused lens | Maximizes coupling efficiency into light pipes and edge-lit LCD backlights with minimal optical loss |
| ESD withstand voltage | 2 kV HBM (JESD22-A114-B) - reduces handling sensitivity during SMT assembly and board test |
Applications
| Automotive Dashboard Backlighting | Telecom Indicator Panels |
|---|---|
|
Use Scenario: Illuminating segmented symbols and analog gauge markings in instrument clusters under varying ambient lighting.

Use Scenario: Status indication on telephone handsets, fax machines, and VoIP endpoint devices. IC Role / Device Role / Timing Role: Standalone visual feedback element powered directly from microcontroller GPIO or dedicated LED sink drivers. Use Value: Low forward voltage (1.8–2.2 V) allows direct drive from 3.3 V I/O rails without series resistor recalibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LHT674-M2P1 | Identical optical binning (M2P1), same PLCC-2 package, but higher RthJA (450 K/W) and no AEC-Q101 certification | Not qualified for automotive use; suitable for industrial/commercial indicator-only roles | Select when AEC-Q101 is not required and OSRAM supply chain preference applies |
| Vishay VLMD31L2N1-GS08 | Lower luminous intensity range (14–35.5 mcd), same wavelength and package, identical AEC-Q101 qualification | Better suited for low-power or glare-sensitive interfaces where lower brightness is preferred | Select when system-level brightness calibration requires lower base intensity tier |
Compared with VLMD31M2P1-GS08, the OSRAM LHT674-M2P1 offers matching optical binning but lacks automotive qualification, while the Vishay VLMD31L2N1-GS08 provides a lower-intensity alternative within the same qualified family-enabling brightness-tiered BOM strategies without redesign.

FAQ
What is the maximum continuous forward current rating for VLMD31M2P1-GS08?
The absolute maximum DC forward current for VLMD31M2P1-GS08 is 30 mA at ambient temperatures ≤60 °C. At higher ambient temperatures, derating is required per Figure 1 in the datasheet-e.g., ~22 mA at 85 °C. Exceeding this limit risks accelerated lumen depreciation and junction overheating. Always verify thermal pad layout and airflow in final design before operating VLMD31M2P1-GS08 near its rated limits.
Is VLMD31M2P1-GS08 compatible with lead-free reflow soldering processes?
Yes, VLMD31M2P1-GS08 is qualified for lead-free IR reflow per J-STD-020, with peak temperature up to 260 °C for ≤10 seconds. The recommended profile includes ramp-up ≤3 °C/s, time above 217 °C ≤30 s, and peak hold at 240–245 °C. Preconditioning to JEDEC Level 2a is mandatory before reflow, and moisture exposure must be controlled per the dry-packaging label instructions to prevent popcorning.
What does the "M2P1" suffix indicate in VLMD31M2P1-GS08?
The "M2P1" suffix denotes the luminous intensity bin: "M" = intensity group (18–22.4 mcd min, 22.4–28 mcd max), "2" = subgroup within M (22.4–28 mcd), and "P1" = further subdivision specifying 45–56 mcd upper range. This precise binning ensures IVmax/IVmin ≤ 1.6 within each 7500-unit GS08 tape reel-critical for consistent brightness in multi-LED arrays like dashboard backlighting.
Does VLMD31M2P1-GS08 have an integrated current-limiting resistor?
No, VLMD31M2P1-GS08 is a bare LED die in PLCC-2 package with no integrated current-limiting resistor. It requires external current control-either via series resistor, constant-current driver IC, or microcontroller PWM with appropriate current-sense feedback. The forward voltage range (1.8–2.2 V at 20 mA) and thermal coefficient (−1.8 mV/K) must be accounted for in driver design to maintain stable luminance over temperature.
Can VLMD31M2P1-GS08 be used in reverse-bias configurations?
The datasheet permits short-term reverse-bias operation (Note 1), but VLMD31M2P1-GS08 is not designed for continuous reverse conduction. Its absolute maximum reverse voltage is only 6 V, and prolonged reverse bias risks degradation of the GaAlAs junction. For bidirectional signaling or AC-driven indicators, use purpose-built dual-LED packages or external protection circuitry-not VLMD31M2P1-GS08 alone.
