Product details
Overview
VEMD4110X01 from Vishay Semiconductors is a high-speed, high-sensitivity silicon PIN photodiode in 0805 SMD package with 0.42 mm² radiant sensitive area, daylight-blocking filter matched to 830–950 nm IR emitters, ±55° half-sensitivity angle, and AEC-Q101 qualification for automotive sensor use.
For engineers reviewing the VEMD4110X01 datasheet, VEMD4110X01 pinout, VEMD4110X01 application, or VEMD4110X01 equivalent, key selection criteria include reverse light current (2.4 μA at 950 nm), rise/fall time (100 ns), spectral bandwidth (740–1040 nm), operating temperature range (−40 °C to +110 °C), and MSL 3 floor life (168 h).
Technical Context
The VEMD4110X01 operates in photovoltaic or photoconductive mode under reverse bias, delivering fast transient response (tr/tf = 100 ns) due to low junction capacitance (2.5 pF at VR = 5 V) and optimized PIN structure. Its spectral peak at 910 nm and full bandwidth from 740 nm to 1040 nm align precisely with common GaAlAs IR emitters.
Integrated daylight-blocking filter suppresses visible-light interference while maintaining high responsivity to near-IR signals; angular sensitivity is symmetric (±55°), supporting robust optical coupling in compact photo-interrupter and proximity-sensing configurations across industrial and automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar photodiode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VEMD4010X01 | Lower sensitivity (Ira = 1.6 μA typ.), same package and spectral response | Less suitable for low-irradiance or long-distance IR link scenarios | Select when cost optimization is prioritized over maximum signal margin |
| TEMDF1000 | TO-46 metal-can package, no daylight filter, wider viewing angle (±75°) | Better suited for free-space optical links requiring broad angular capture | Choose when mechanical mounting allows larger through-hole format and ambient light is controlled |

FAQ
What is the peak wavelength sensitivity of the VEMD4110X01?
The VEMD4110X01 has a peak wavelength sensitivity (λp) of 910 nm, with a full spectral bandwidth spanning 740 nm to 1040 nm. This matches common GaAlAs infrared emitters and ensures optimal responsivity in photo-interrupter and proximity-sensing circuits. The VEMD4110X01 achieves its highest reverse light current (2.4 μA typ.) at 950 nm under standardized irradiance conditions.
Is the VEMD4110X01 suitable for automotive applications?
Yes, the VEMD4110X01 is AEC-Q101 qualified and rated for operation from −40 °C to +110 °C, making it suitable for under-hood and cabin automotive applications such as seat occupancy detection, gear position sensing, and HVAC airflow monitoring. Its daylight-blocking filter and stable reverse light current performance across temperature ensure reliability in real-world vehicle environments. The VEMD4110X01 meets automotive-grade moisture sensitivity (MSL 3) and reflow requirements.
What is the reverse voltage rating for the VEMD4110X01?
The absolute maximum reverse voltage rating for the VEMD4110X01 is 20 V at Tamb = 25 °C. For normal operation, Vishay specifies VR = 5 V in key performance tests-including reverse light current (Ira), rise/fall time, and capacitance measurements. Operating above 5 V increases dark current and may degrade long-term stability; the VEMD4110X01 is not intended for high-voltage photodiode applications.
Does the VEMD4110X01 require external filtering for visible-light rejection?
No-the VEMD4110X01 integrates a daylight-blocking filter matched to IR emitters operating between 830 nm and 950 nm. This built-in filter suppresses visible-light response while preserving high near-IR quantum efficiency. As confirmed in the datasheet, the device delivers stable reverse light current (2.4 μA) under 950 nm illumination even in brightly lit indoor environments. No external optical filter is needed when paired with compatible IR sources. The VEMD4110X01's spectral selectivity is intrinsic to its construction.
What is the recommended PCB footprint for the VEMD4110X01?
The recommended PCB footprint for the VEMD4110X01 follows the 0805 outline with pad dimensions optimized for solder joint reliability: 0.9 mm × 1.3 mm pads spaced 1.45 mm center-to-center, matching the anode/cathode terminal layout shown in Figure 5 of the datasheet. Vishay provides verified land patterns and 3D models on their website. Proper thermal relief and solder mask definition are critical to avoid tombstoning during lead-free reflow. The VEMD4110X01's footprint supports automated placement and AOI inspection in high-volume manufacturing.
