Product details
Overview
MV8742 from Fairchild Semiconductor is a super-bright T-1 3/4 (5 mm) water-clear orange LED with 620 nm peak wavelength, 400 mcd minimum luminous intensity at 20 mA, and 2.8 V maximum forward voltage - used in outdoor status indicators, industrial control panels, and high-visibility signage.
For engineers reviewing the MV8742 datasheet, pinout, applications, or equivalent options, key selection factors include its 45° viewing angle, 40 mA continuous forward current rating, -40°C to +100°C operating temperature range, and cathode identification via flat lead edge.
Technical Context
This AlInGaP-based LED emits narrow-band orange light with dominant wavelength 615 nm and spectral line half-width 20 nm, enabling precise color matching in multi-LED arrays. Its water-clear epoxy lens maximizes optical coupling efficiency without diffusion.
The device operates within strict thermal limits: power dissipation capped at 100 mW, with forward current derated linearly above 25°C ambient - dropping to 0 mA at 100°C per Fig. 5. Lead soldering tolerance is specified at 260°C for 5 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Wavelength | 620 nm - defines spectral center for orange emission; critical for color-critical UIs and photometric compliance. |
| Luminous Intensity | Min 400 mcd @ 20 mA - ensures visibility under daylight or high-ambient-light conditions. |
| Forward Voltage | Max 2.8 V @ 20 mA - determines minimum supply headroom and series resistor sizing. |
| Viewing Angle | 45° - provides focused beam for directional indication without excessive lateral spill. |
| Continuous Forward Current | 40 mA - sets maximum steady-state drive level; exceeds typical 20 mA reference for enhanced brightness. |
| Operating Temperature | -40°C to +100°C - supports deployment in uncontrolled industrial or outdoor enclosures. |
Pinout & Package
T-1 3/4 (5 mm) through-hole package with 2.54 mm (100 mil) lead spacing; cathode identified by flat edge on lead frame. Body diameter 5.08 mm, flange-to-tip length 8.89 mm, lead diameter 0.58 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive DC input | Connected to current-limiting resistor; requires ≥2.8 V overhead for full brightness at 20 mA. |
| Cathode | Ground return / negative terminal | Identified by flat edge on lead; must be tied to lowest system potential for conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Super-bright AlInGaP die | Delivers 400–600 mcd output - enables legibility at >3 m distance in daylight. |
| Water-clear epoxy lens | Preserves spectral purity and peak intensity; avoids diffusion loss seen in diffused LEDs. |
| 45° viewing angle | Concentrates luminance into usable cone - reduces backlight bleed and improves contrast in panel layouts. |
| Industrial-grade thermal range | Rated for -40°C to +100°C operation - eliminates need for external thermal derating in most embedded housings. |
Applications
| Outdoor Status Indicators | Industrial Control Panels |
|---|---|
Use Scenario: LED mounted on weatherproof enclosure front panel indicating power-on, fault, or mode status in direct sunlight. IC Role / Device Role / Timing Role: Light-emitting element driven directly by microcontroller GPIO or discrete transistor switch. Use Value: 400 mcd minimum intensity and 45° beam ensure readability at 2+ meters under 10,000 lux ambient illumination. | Use Scenario: Multi-color status array on PLC I/O module faceplate showing input/output state per channel. IC Role / Device Role / Timing Role: Discrete visual indicator paired with current-limiting resistor; no timing or logic function. Use Value: Water-clear lens and 620 nm peak enable consistent orange hue across batches - critical for operator recognition standards. |
| High-Visibility Signage | Transportation Annunciators |
Use Scenario: Backlit alphanumeric segment in emergency exit sign or directional marker requiring long-life visible output. IC Role / Device Role / Timing Role: Steady-state emitter powered from regulated 5 V rail via fixed resistor. Use Value: 100 mW power dissipation limit and 40 mA IF rating allow sustained operation without thermal rolloff over 50,000-hour lifetime. | Use Scenario: Dashboard warning lamp in rail or bus control cabin where vibration, temperature swing, and EMI are present. IC Role / Device Role / Timing Role: Ruggedized optical indicator replacing incandescent bulbs; driven by open-collector driver. Use Value: Solid-state reliability and -40°C to +100°C rating eliminate cold-start failures and thermal cycling fatigue. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar orange LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| L-530RDT-1U | 630 nm peak, 350 mcd min @ 20 mA, 2.6 V max VF | Narrower 30° viewing angle; lower intensity but tighter beam | Select for higher directionality where off-axis visibility must be minimized. |
| HLMP-ED85 | 625 nm peak, 500 mcd min @ 20 mA, 2.7 V max VF, same T-1 3/4 package | Broader 60° viewing angle; higher intensity but wider dispersion | Select when wider field-of-view is needed for multi-position operator access. |
Compared with MV8742, L-530RDT-1U trades intensity for beam focus, while HLMP-ED85 increases total lumen output at the cost of angular spread - both retain identical 2.54 mm lead spacing and through-hole mounting compatibility.

FAQ
What is the peak emission wavelength of the MV8742?
The MV8742 has a peak emission wavelength of 620 nm, with dominant wavelength at 615 nm and spectral line half-width of 20 nm. This narrow-band orange output is achieved using an AlInGaP semiconductor die and is confirmed in the Electrical/Optical Characteristics table on page 2 of the official datasheet. The MV8742 maintains this spectral profile across its rated operating temperature range.
What is the minimum luminous intensity specification for MV8742 at 20 mA?
The MV8742 is rated for a minimum luminous intensity of 400 mcd at 20 mA forward current and 25°C ambient temperature. Its typical intensity is 600 mcd under the same conditions. This value is measured at the optical axis and reflects performance of the water-clear epoxy lens and AlInGaP chip combination. The MV8742 outperforms MV8741 (250 mcd min) in this parameter.
Does MV8742 have polarity marking, and how is the cathode identified?
Yes, the MV8742 uses a flat edge on one lead to denote the cathode terminal - consistent with standard T-1 3/4 LED packaging conventions. This flat feature is shown in the Package Dimensions diagram on page 2 of the datasheet. When installing the MV8742, the flattened lead must be connected to circuit ground or the low-side switch to ensure proper forward biasing and light emission.
What is the maximum continuous forward current rating for MV8742?
The MV8742 has a maximum continuous forward current rating of 40 mA at 25°C ambient temperature. At higher temperatures, this rating decreases linearly per the Current Derating Curve (Fig. 5), reaching zero at 100°C. Exceeding 40 mA continuously risks accelerated degradation. The MV8742 can tolerate 160 mA peak current only under pulsed conditions (1 kHz, 10% duty cycle), as specified in Absolute Maximum Ratings.
Is MV8742 suitable for reflow soldering?
No, the MV8742 is not rated for reflow soldering. Its Absolute Maximum Ratings specify lead soldering at 260°C for 5 seconds - a hand-soldering or wave-soldering condition. Reflow profiles typically exceed this thermal exposure, risking epoxy discoloration, bond wire failure, or internal delamination. For surface-mount alternatives compatible with reflow, consider checking ON Semiconductor's NSI50010YT1G or similar SMD orange LEDs - not the MV8742.
