onsemi MV8317

Overview

MV8317 from Fairchild Semiconductor is a super-bright yellow T-1 3/4 (5 mm) LED lamp with water-clear epoxy lens, 590 nm peak wavelength, 12° viewing angle, and 4500 mcd minimum luminous intensity at 20 mA - used in high-visibility status indicators and outdoor signage.

For engineers reviewing the MV8317 datasheet, pinout, applications, or equivalent options, key selection factors include narrow-beam optical performance, thermal derating above 25°C ambient, forward voltage consistency (2.1 V typ), and cathode identification via flat edge on the T-1 3/4 package.

Technical Context

The MV8317 uses an AlInGaP semiconductor die optimized for yellow emission at 590 nm with 15 nm spectral line half-width, delivering concentrated light output via a 12° radiation pattern. Its water-clear epoxy lens preserves optical clarity without diffusion.

Rated for continuous forward current of 30 mA and peak current of 160 mA (1 kHz, 10% duty), the device operates across –40°C to +100°C and requires 260°C soldering for ≤5 seconds. Reverse voltage is limited to 5 V.

Key Specifications

Pinout & Package

Compared with MV8317, L-59EGW offers lower cost at reduced intensity, while TLR1200 provides higher output and wider dispersion - both require verification of mechanical fit and thermal margin in final layout.

Availability

MV8317 is available at Aetrix Electronics and suitable for outdoor signage, industrial HMI panels, and automotive dashboard indicators requiring stable component supply and long-term obsolescence management.

Supply support for MV8317 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Fairchild Semiconductor was a U.S.-based analog and discrete semiconductor manufacturer, acquired by ON Semiconductor in 2016; known for high-reliability optoelectronics and power devices.

The MV8317 belongs to the MV831X super-bright yellow LED family, engineered for high-intensity visual signaling in harsh environments where color accuracy and beam control are critical.

FAQ

What is the peak wavelength and spectral width of the MV8317?

The MV8317 has a peak wavelength of 590 nm with a spectral line half-width of 15 nm, measured at 20 mA. This narrow bandwidth ensures consistent yellow chromaticity essential for regulatory-compliant signaling applications. The AlInGaP die technology maintains this spectral stability across its operating temperature range.

What is the maximum continuous forward current rating for the MV8317?

The MV8317 is rated for 30 mA continuous forward current at 25°C ambient. Derating is required above 25°C - e.g., ~25 mA at 50°C and ~15 mA at 80°C - per the current derating curve in the datasheet. Exceeding 30 mA continuously risks accelerated lumen depreciation and reduced lifetime.

How is cathode polarity identified on the MV8317 package?

The MV8317 uses dual cathode identification: a flat edge on the lens housing and a shorter lead length. These features comply with JEDEC EIA-481 standards for T-1 3/4 LEDs. Correct orientation is critical - reverse bias beyond 5 V may cause irreversible junction damage.

Does the MV8317 require external current limiting?

Yes, the MV8317 requires an external series current-limiting resistor or constant-current driver. With a typical forward voltage of 2.1 V at 20 mA, the resistor value must be calculated based on supply voltage and desired operating current. Unregulated voltage drive will cause thermal runaway and premature failure.

Is the MV8317 suitable for outdoor use under UV exposure?

Yes, the MV8317's water-clear epoxy lens is formulated for UV resistance and retains optical clarity after prolonged outdoor exposure. Its –40°C to +100°C operating range and solid-state construction support deployment in non-hermetic outdoor enclosures, provided ingress protection (e.g., IP65) is implemented at the system level.
