Product details
Overview
TEMT6202FX01 from Vishay Semiconductors is a silicon NPN epitaxial planar phototransistor ambient light sensor in a surface-mount 0805 package (2.0 × 1.25 × 0.85 mm), optimized for human-eye spectral response with peak sensitivity at 550 nm, 450–610 nm spectral bandwidth, ±60° half-sensitivity angle, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TEMT6202FX01 datasheet, TEMT6202FX01 pinout, TEMT6202FX01 application, or TEMT6202FX01 equivalent, this page delivers verified phototransistor specifications including photo current (7.5–39 μA at 100 lx), dark current (≤50 nA), collector-emitter breakdown voltage (6 V), thermal resistance (450 K/W), and spectral responsivity alignment to CIE illuminant A - critical for display dimming and automotive cabin sensing design.
Technical Context
The TEMT6202FX01 operates as a two-terminal phototransistor with no base connection, relying on incident visible light to generate collector current. Its spectral response is filtered to suppress near-infrared radiation while matching photopic luminosity function, enabling accurate ambient light measurement under white LED and CIE illuminant A sources.
It exhibits a temperature coefficient of photo current of +0.9%/K (white LED) and +1.18%/K (CIE illuminant A), with collector-emitter saturation voltage ≤0.1 V at 0.45 μA output. The device is rated for operation from −40 °C to +100 °C and qualified per AEC-Q101 for automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ambient light sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VEMT2500X01 | Higher typical photo current (12–45 μA at 100 lx); same 0805 package and spectral response; no AEC-Q101 qualification. | Suitable for consumer electronics where automotive qualification is not required; slightly higher sensitivity improves low-light SNR. | Select VEMT2500X01 when AEC-Q101 is unnecessary and higher binned IPCE improves margin in low-illumination use cases. |
| TEMT6200FX01 | Identical package, pinout, and spectral characteristics; differs only in binned photo current range (7.5–39 μA vs. TEMT6202FX01's documented 7.5–39 μA - confirmed identical binning structure per Vishay doc#81317 rev.1.9). | No functional difference in application; both qualified for automotive and consumer ambient light sensing. | TEMT6200FX01 is a direct form-fit-function alternative with identical electrical and mechanical specs; interchangeability verified per Vishay documentation. |
Compared with TEMT6202FX01, VEMT2500X01 offers higher sensitivity but lacks automotive qualification, while TEMT6200FX01 provides identical performance and qualification - making it a drop-in replacement where sourcing flexibility is needed without design change.

FAQ
What is the spectral response range of the TEMT6202FX01?
The TEMT6202FX01 has a spectral bandwidth of 450 nm to 610 nm with peak sensitivity at 550 nm, closely matching the photopic luminosity function of the human eye. This range is confirmed in the "Basic Characteristics" table of Vishay document #81317, and the device includes a built-in filter to suppress near-infrared radiation outside this band. The TEMT6202FX01 thus delivers illumination measurements correlated to perceived brightness rather than raw irradiance.
Is the TEMT6202FX01 pin-compatible with other Vishay phototransistors in the same package?
Yes - the TEMT6202FX01 uses a standard two-terminal 0805 phototransistor configuration with emitter and collector terminals only, matching the pinout of TEMT6200FX01 and VEMT2500X01. All share identical physical dimensions (2.0 × 1.25 × 0.85 mm) and terminal orientation per Vishay package drawing #19757. No PCB layout changes are required when substituting within this family.
What is the maximum operating temperature for the TEMT6202FX01?
The TEMT6202FX01 is rated for continuous operation from −40 °C to +100 °C ambient temperature, with junction temperature limited to 100 °C. This rating is validated under AEC-Q101 stress testing and applies across its full electrical specification range. Derating of photo current and dark current versus temperature is documented in Figures 2 and 3 of Vishay document #81317.
Does the TEMT6202FX01 require a base connection or external biasing components?
No - the TEMT6202FX01 is a two-terminal NPN phototransistor with no base terminal. It operates in common-emitter configuration using only a collector pull-up resistor (typically 10–100 kΩ) and grounded emitter. No external biasing circuitry or base resistors are needed, simplifying interface design and reducing BOM count for the TEMT6202FX01.
How is the TEMT6202FX01 binned, and what does the 'FX01' suffix indicate?
The 'FX01' suffix denotes Vishay's standard binned phototransistor variant with three sensitivity groups (A/B/C) defined by photo current at 100 lx: Group A (7.5–15 μA), Group B (12–24 μA), and Group C (19.5–39 μA). The TEMT6202FX01 is shipped pre-binned per reel, with group labeling on packaging - no user selection of group is possible, and designs must accommodate the full specified IPCE range.
