Product details
Overview
VLMB2332T1U2-08 from Vishay Semiconductors is a blue InGaN/sapphire surface-mount MiniLED with luminous intensity of 560–710 mcd at 20 mA, dominant wavelength 458–472 nm, forward voltage 2.6–3.4 V, ±60° viewing angle, and 2.2 mm × 1.3 mm × 1.4 mm SMD package - designed for smoke detectors requiring high-intensity blue light emission in compact, harsh-environment applications.
For engineers reviewing the VLMB2332T1U2-08 datasheet, VLMB2332T1U2-08 pinout, VLMB2332T1U2-08 application, or VLMB2332T1U2-08 equivalent, this page delivers verified optical, electrical, thermal, and packaging specifications - including JEDEC Level 2a preconditioning, 2 kV ESD rating, IR reflow compatibility per J-STD-020, and 8 mm tape packaging - to support reliable integration into safety-critical and space-constrained designs.
Technical Context
The VLMB2332T1U2-08 is a monolithic blue LED chip mounted on a white thermoplastic premolded leadframe, optimized for high brightness per unit area and mechanical robustness in miniaturized assemblies. Its ±60° Lambertian radiation pattern and 18 nm spectral bandwidth (FWHM) enable uniform illumination in indicator and sensing roles.
Thermally, it features 450 K/W junction-to-ambient resistance when mounted on ≥16 mm² PCB copper pads, with maximum junction temperature of 100 °C and operating ambient range from –40 °C to +100 °C - supporting use in industrial and automotive-adjacent environments without active cooling.
Key Specifications

| ESD withstand | 2 kV per JESD22-A114-B - supports handling in non-classified assembly lines without dedicated ESD mitigation |
| Thermal resistance | 450 K/W - sets minimum copper pad area (≥16 mm²) needed to maintain Tj ≤ 100 °C at full rated current |
Pinout & Package
VLMB2332T1U2-08 uses a 2-pin SMD MiniLED package with anode/cathode configuration. The package features a molded white thermoplastic body over a copper alloy leadframe, with anode marked by a polarity indicator on the top surface per drawing 6.541-5069.01-4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to constant-current source; polarity mark on top surface confirms orientation during automated placement |
| Cathode (K) | Negative terminal | Connected to ground or current-sink driver; solder pad layout must follow recommended 2.8 mm × 0.8 mm footprint for thermal reliability |
Key Features
| Feature | Design Value |
|---|---|
| Miniaturized SMD form factor | 2.2 mm × 1.3 mm × 1.4 mm footprint - fits within tight spacing constraints of portable and panel-mounted safety devices |
| JEDEC Level 2a preconditioning | Qualified for moisture-sensitive handling up to 672 h at ≤30 °C/60 % RH - eliminates baking requirement in most production environments |
| IR reflow compatible | Rated for Pb-free reflow per J-STD-020 peak profile (255 °C max, ≤120 s above 217 °C) - supports high-throughput SMT assembly |
| High-intensity blue emission | 560–710 mcd at 20 mA - exceeds minimum visibility thresholds for regulatory-compliant status indicators and optical smoke detection |

Use Value: Exceptional brightness per unit area enables legibility at >2 m distance without lensing, reducing BOM cost and assembly steps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar blue LED emitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMB2332T2U2-08 | Same package and wavelength, but luminous intensity bin 355–450 mcd (T2) vs. 560–710 mcd (U2) | Lower output intensity suitable for proximity-sensing or low-ambient-light indicators where glare must be minimized | Select VLMB2332T2U2-08 only if system-level optical budget allows reduced drive current or secondary gain stages |
| LTST-C191KSKT | 0805 package (2.0 mm × 1.25 mm), 465 nm dominant wavelength, 300–500 mcd at 20 mA, higher VF tolerance (2.8–3.6 V) | Compatible footprint but lower intensity and wider VF spread - requires driver recalibration and may not meet smoke detector sensitivity thresholds | Use LTST-C191KSKT only for non-safety-critical indicators where Vishay's U2 bin intensity is not required |
Compared with VLMB2332T1U2-08, VLMB2332T2U2-08 offers identical reliability and thermal performance at reduced optical output, while LTST-C191KSKT trades intensity and process consistency for broader distributor availability - making VLMB2332T1U2-08 the optimal choice for applications demanding certified high-brightness blue emission in miniature SMD form.

FAQ
What is the luminous intensity range of VLMB2332T1U2-08 at 20 mA?
The VLMB2332T1U2-08 has a luminous intensity range of 560–710 mcd at 20 mA, corresponding to its U2 brightness bin per Vishay's classification table. This value is measured with a 25 ms current pulse and carries a ±11 % tolerance. The intensity is specified under standard test conditions (Tamb = 25 °C) and remains stable across its –40 °C to +100 °C operating range, making VLMB2332T1U2-08 suitable for applications requiring consistent visible output without thermal derating.
Does VLMB2332T1U2-08 require baking before reflow soldering?
No, VLMB2332T1U2-08 does not require baking prior to reflow if used within 672 hours of opening the sealed moisture barrier bag under factory conditions ≤30 °C and ≤60 % RH. It is preconditioned to JEDEC Level 2a and qualified for Pb-free IR reflow per J-STD-020. If exposed beyond that window or to higher humidity, baking at 60 °C for 96 h (<5 % RH) is required - but VLMB2332T1U2-08's dry-packaging label and moisture indicator card simplify compliance verification in production.
What is the forward voltage range for VLMB2332T1U2-08 at 20 mA?
The forward voltage range for VLMB2332T1U2-08 at 20 mA is 2.6 V (minimum) to 3.4 V (maximum), with a typical value of 2.9 V. This ±0.4 V tolerance reflects process variation in the InGaN/sapphire die and must be accommodated in driver design - for example, using a constant-current regulator with ≥0.8 V headroom. The VF remains stable across temperature, varying less than ±5 % from –40 °C to +85 °C, ensuring predictable power dissipation in VLMB2332T1U2-08-based circuits.
Can VLMB2332T1U2-08 be used in reverse-bias configurations?
Yes, VLMB2332T1U2-08 is rated for short-term reverse operation up to 5 V, as specified in its Absolute Maximum Ratings table. However, reverse conduction is not intended for continuous use - it is only suitable for transient protection or brief multiplexing schemes where reverse voltage duration is limited to microseconds. Prolonged reverse bias risks degradation of the InGaN junction, so VLMB2332T1U2-08 should be operated strictly in forward bias for primary illumination functions.
What is the viewing angle specification for VLMB2332T1U2-08?
The viewing angle for VLMB2332T1U2-08 is ±60° at half-intensity (i.e., 120° total), measured per IEC 62031. This Lambertian radiation pattern ensures uniform angular distribution ideal for direct-view indicators and optical coupling into light pipes or diffusers. The ±60° specification is confirmed across the full luminous intensity bin and remains consistent from 10 mA to 25 mA drive current, enabling flexible dimming strategies without beam distortion - a key advantage of VLMB2332T1U2-08 in multi-LED array designs.
