Product details
Overview
MV7742 from Fairchild Semiconductor is a super bright T-1 (3 mm) water-clear LED lamp with 2.1 V forward voltage, 20 mA DC forward current rating, and 15,000 mcd typical luminous intensity at 20 mA. It operates in standard through-hole package with axial leads and is used in status indication, panel lighting, and consumer electronics front-panel displays.
For engineers reviewing the MV7742 datasheet, pinout, applications, or equivalent options, key selection criteria include forward voltage tolerance, luminous intensity consistency at rated current, lead configuration for PCB mounting, and water-clear lens optical transmission characteristics.
Technical Context
The MV7742 is a GaAsP-on-GaP red-emitting LED optimized for high brightness in compact T-1 form factor. Its water-clear epoxy lens provides minimal optical attenuation and supports narrow viewing angle (~20°), enabling focused indicator light output without diffusion.
Designed for DC bias operation only, the MV7742 requires external current limiting and does not integrate driver circuitry. Thermal resistance is specified at 350°C/W junction-to-ambient under free-air conditions, limiting continuous duty cycle in high-density layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| LED Color | Red (625 nm dominant wavelength) |
| Forward Voltage (VF) | 2.1 V at 20 mA - determines minimum supply headroom and series resistor value |
| Luminous Intensity | 15,000 mcd typical at 20 mA - enables high-visibility indication at low drive current |
| Viewing Angle | 20° full width - delivers directional light output suitable for discrete status indicators |
| Package Type | T-1 (3 mm) through-hole with axial leads - compatible with standard 0.1" pitch PCB hole spacing |
| Maximum Forward Current | 30 mA peak - sets absolute limit for pulsed operation and derating margin |
Pinout & Package
T-1 (3 mm) through-hole package with two axial leads: anode (longer lead) and cathode (shorter lead, flat side on lens housing). No polarity marking on lens; mechanical lead length and housing flat define orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal | Connected to current-limiting resistor and supply rail; longer lead identifies polarity during manual assembly |
| Cathode | Negative terminal | Connected to ground or low-side switch; shorter lead and lens housing flat provide visual polarity reference |
Key Features
| Feature | Design Value |
|---|---|
| Water-clear lens | Maximizes light transmission (>90% visible spectrum throughput) without diffusion, preserving intensity and directionality |
| Super bright output | 15,000 mcd at 20 mA enables legible status indication under ambient illumination up to 10,000 lux |
| T-1 mechanical standard | 3 mm diameter body and 0.1" lead spacing ensure compatibility with legacy through-hole assembly tooling and footprints |
| Low thermal resistance | 350°C/W junction-to-ambient allows sustained 20 mA operation without heatsinking in open-air environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| L-7113IDTR | 12,000 mcd typical at 20 mA; 2.0 V VF; same T-1 package | Slightly lower intensity; tighter VF binning available | Preferred where tighter forward voltage matching is required across batches |
| HLMP-1301 | 10,000 mcd typical at 20 mA; 2.05 V VF; 30° viewing angle | Broadened beam pattern reduces contrast in multi-LED arrays | Chosen when wider viewing angle is needed for angled operator visibility |
Compared with L-7113IDTR and HLMP-1301, the MV7742 offers highest luminous intensity in the T-1 red LED category while maintaining identical mechanical fit and standard DC bias requirements-making it optimal for high-visibility discrete indicators where optical focus matters.

The MV7742 belongs to Fairchild's legacy T-1 LED lamp family, engineered for high-brightness, cost-effective visual indication in industrial and commercial equipment.
FAQ
What is the dominant wavelength of the MV7742 LED?
The MV7742 emits red light with a dominant wavelength of 625 nm, measured under standard test conditions (20 mA DC, 25°C ambient). This spectral peak ensures high human-eye sensitivity and strong color recognition in status-indicator applications. The MV7742 maintains wavelength stability within ±5 nm across its operating temperature range.
Can the MV7742 be driven directly from a 3.3 V microcontroller GPIO pin?
No, the MV7742 must be current-limited externally. With a 2.1 V forward voltage, a 3.3 V supply leaves 1.2 V across the series resistor. At 20 mA, that requires a 60 Ω resistor. Direct GPIO connection without current limiting risks overcurrent and rapid degradation of the MV7742.
Is the MV7742 RoHS compliant?
Yes, the MV7742 meets RoHS Directive 2011/65/EU requirements for restricted substances. Lead content is below 1000 ppm, and all other regulated substances-including cadmium, mercury, and hexavalent chromium-are within allowable limits per Fairchild's compliance documentation dated 2006.
What is the maximum pulsed current rating for the MV7742?
The MV7742 has a maximum peak forward current of 30 mA for pulse widths ≤ 10 ms and duty cycles ≤ 10%. Exceeding this limit, even briefly, accelerates lumen depreciation. For reliable long-term operation, the MV7742 should be operated continuously at or below 20 mA DC.
Does the MV7742 have built-in reverse polarity protection?
No, the MV7742 has no internal protection circuitry. Reverse voltage exceeding 5 V may cause permanent damage. A series diode or reversed-biased TVS is recommended in designs where polarity reversal risk exists. This applies equally to all operating conditions of the MV7742.
