SHORT INTRODUCTION TO PART NUMBERS
The performance of Vishay IR receivers is characterized by the type of microchip (IC) employed, the package, the automatic
gain control (AGC), and the band-pass frequency. These features are included in the part number nomenclature, as illustrated
above. The preamble TSxP already indicates which application the receiver is appropriate for: remote control, sensor
applications, or repeater and learning applications.
After the preamble, a number with five digits specifies the receiver. Further extensions assign special mechanical and package
options.

Introduction to IR Receiver Part Numbers
IC
The first digit after the preamble is reserved for the IC. Please note that “5” or a blank digit both indicate a Methone IC. A blank
digit means that in this case the number consists of four digits only. Furthermore, there are some exceptions for the Heimdall
package naming, where package number and IC number cannot be separated, but consist of a two-digit number. For example,
a receiver with Mneme IC, Heimdall package, AGC4, and 38 kHz band-pass frequency would be referred to as TSOP15438.
The microchip contains logic circuits that are employed to distinguish between noise and signal. Consequently, the choice of
the IC has impact on the dark sensitivity of the receiver as well as the robustness against different disturbance sources like
fluorescent lamps or Wi-Fi.
PACKAGE
The second digit specifies the type of receiver package. A choice can be made between SMD (Minimold P1xTR or DF1P,
Heimdall, Panhead, Belobog, TVCastSMD) and through-hole assembly (Minicast, Mold, Minimold, TVCast, Cast). The Mold
package is available with two different pinnings and therefore employs two different numbers. Both the Minimold and the
TVCast packages are unique in that both packages allow for both SMD and through-hole assembly. In the case of SMD
assembly, the latter is called TVCastSMD, and the SMD versions of both packages must be ordered in tape and reel.
AGC
The third digit defines the automatic gain control (AGC). The AGC controls which data formats are accepted and which
disturbance sources are suppressed by the receiver. The odd-numbered AGCs (1, 3, 5) are designed for short-burst reception,
defined as six or more carrier cycles per burst, and the even-numbered AGCs (2, 4, 6) are designed for long bursts, defined as
10 or more carrier cycles per burst. The higher the AGC number, the more robust will be the disturbance noise suppression
characteristics, but also the number of codes interpreted as noise will increase. It is essential that the designer test the intended
remote control code in the worst-case disturbed ambient to determine the optimal AGC.

BAND PASS FREQUENCY
Vishay IR receivers apply a band-pass filter that is tuned to a specific modulation frequency in the kHz regime, which enables
them to pick up a weak signal even under extremely noisy environmental conditions. The band-pass filter’s Q-factor is low, so
modulation frequencies outside the center frequency will often be received, but at a lower sensitivity. The last two digits indicate
the band-pass frequency in kHz.

VSOP
The VSOP products are chip packages for IR receivers, which require an external photodiode. The external photodiode should
typically contain an IR filter to eliminate wavelengths shorter than 940 nm, although operation without this filter is conceivable
for exotic applications, e.g. underwater where blue light is better propagated.
The nomenclature is similar to the TSxP receivers.
