Product details
Overview
MV7842 from Fairchild Semiconductor is a super bright T-1 (3mm) water-clear LED lamp with 20 mA forward current rating, 3.6 V typical forward voltage, and 15,000 mcd minimum luminous intensity at 20 mA. It serves as a visible status indicator in industrial control panels, consumer appliance displays, and instrumentation front panels.
For engineers reviewing the MV7842 datasheet, pinout, applications, or equivalent options, key selection factors include its water-clear epoxy lens for maximum light transmission, narrow viewing angle of ±15°, and compatibility with standard through-hole PCB mounting and wave soldering processes.
Technical Context
The MV7842 is a discrete visible-light emitter optimized for high-brightness signaling under DC or pulsed drive conditions. Its GaAsP-on-GaP semiconductor structure delivers stable chromaticity and low thermal droop up to 20 mA continuous operation.
Rated for 100,000-hour lifetime at 25°C ambient and 20 mA drive, the device features a cathode-anode polarity configuration with axial leads and conforms to JEDEC TO-18 mechanical outline standards for T-1 packages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Package | T-1 (3mm) axial lead, JEDEC TO-18 compliant |
| Luminous Intensity | 15,000 mcd min at 20 mA - enables clear visibility at >2 m distance in ambient light |
| Forward Voltage | 3.6 V typ at 20 mA - sets minimum supply headroom for series resistor design |
| Viewing Angle | ±15° - provides focused beam for discrete indicator use without optical diffusers |
| Reverse Voltage | 5 V max - defines absolute maximum blocking capability during reverse bias transients |
| Operating Temp | −40°C to +100°C - supports deployment in industrial enclosures without derating |
Pinout & Package
T-1 (3mm) package with axial leads: anode (longer lead) and cathode (shorter lead, flat side on epoxy body). Standard through-hole mounting; lead spacing 2.54 mm (0.1 inch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal | Connected to current-limiting resistor and supply rail; longer lead identifies polarity |
| Cathode | Negative terminal | Connected to ground or sink driver; shorter lead and flat epoxy edge mark cathode |
Key Features
| Feature | Design Value |
|---|---|
| Water-clear epoxy lens | Maximizes luminous output by minimizing internal light absorption vs. diffused or tinted lenses |
| High luminous intensity | 15,000 mcd minimum ensures legibility under factory lighting and daylight exposure |
| Narrow viewing angle | ±15° beam pattern prevents crosstalk between adjacent indicators on dense control panels |
| JEDEC TO-18 compliance | Guarantees mechanical interchangeability with legacy T-1 LED footprints and assembly tooling |
Applications
| Industrial Control Panel Indicator | Consumer Appliance Status Light |
|---|---|
Use Scenario: Power-on, fault, or mode indication on PLC I/O modules and HMI overlays. IC Role / Device Role / Timing Role: Discrete visual status emitter driven directly by microcontroller GPIO or logic buffer. Use Value: High brightness and narrow beam ensure unambiguous operator recognition amid panel clutter and ambient glare. | Use Scenario: Cycle completion or door-lock status on washing machines and microwave ovens. IC Role / Device Role / Timing Role: Through-hole mounted indicator integrated into appliance mainboard or display subassembly. Use Value: Water-clear lens and 100°C operating range withstand repeated thermal cycling and steam exposure in sealed enclosures. |
| Test Equipment Front Panel | Medical Device UI Indicator |
Use Scenario: Signal presence, calibration status, or error condition on oscilloscope or multimeter front panels. IC Role / Device Role / Timing Role: Direct-drive LED with series resistor; no active driver IC required. Use Value: Stable chromaticity and 100,000-hour lifetime reduce maintenance frequency in benchtop instruments. | Use Scenario: Non-critical system status (e.g., power, USB connection) on diagnostic equipment housings. IC Role / Device Role / Timing Role: Visual feedback component not part of life-support signal chain per Fairchild's policy statement. Use Value: Complies with Fairchild's stated restriction for non-life-support applications while meeting ESD robustness and labeling requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar visible indicator LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| L-7113IDT | Same T-1 package, 12,000 mcd min, 3.4 V VF - lower intensity, slightly lower VF | Suitable where reduced brightness suffices and lower drive voltage eases resistor selection | Select L-7113IDT when board space and thermal budget allow marginally lower output |
| TLR-3301 | T-1 package, 18,000 mcd min, 3.8 V VF - higher intensity, higher VF | Better for long-distance visibility but requires higher supply headroom | Choose TLR-3301 only if >15,000 mcd is mandatory and 3.8 V VF aligns with system rail constraints |
Compared with MV7842, L-7113IDT offers lower drive voltage but reduced intensity, while TLR-3301 delivers higher brightness at the cost of increased forward voltage - both require identical PCB footprint but differ in optical and electrical trade-offs.

FAQ
What is the maximum forward current rating for the MV7842?
The MV7842 has a maximum continuous forward current rating of 20 mA. Exceeding this value risks accelerated lumen depreciation and reduced lifetime. Pulse operation at higher peak currents is not specified in Fairchild's documentation for the MV7842, so sustained 20 mA is the design limit for reliability-critical applications.
Does the MV7842 have a built-in current-limiting resistor?
No, the MV7842 does not include an integrated current-limiting resistor. It is a bare LED die in a T-1 package requiring an external series resistor or constant-current driver. Designers must calculate resistance based on supply voltage, 3.6 V typical forward voltage, and desired 20 mA operating current to ensure safe and stable operation of the MV7842.
Is the MV7842 RoHS compliant?
Yes, the MV7842 is RoHS compliant per Fairchild Semiconductor's product documentation and packaging markings. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits, making it suitable for environmentally regulated electronics manufacturing.
What is the viewing angle specification for the MV7842?
The MV7842 has a viewing angle of ±15°, meaning full luminous intensity is maintained within a 30° cone centered on the optical axis. This narrow angular distribution supports discrete, non-overlapping indication in tightly spaced arrays - a key design feature confirmed in Fairchild's published optical data for the MV7842.
Can the MV7842 be used in life-support systems?
No - Fairchild explicitly states that the MV7842 is not authorized for use in life-support devices or systems without express written approval. As a discrete indicator LED, it is intended for non-critical status signaling only; any application involving surgical implantation, life-sustaining function, or safety-critical failure modes requires formal review and approval before using the MV7842.
