Vishay Semiconductor Opto Division TSMP98100

Overview

TSMP98100 from Vishay Semiconductors is a miniaturized infrared (IR) sensor module designed for receiving modulated 38 kHz carrier signals in remote control systems. It integrates a PIN photodiode and preamplifier in a single epoxy package with built-in IR filter, operates from 2.0 V to 5.5 V, delivers carrier-out output for repeater applications, and achieves up to 12 m transmission distance with TSAL6200 emitter under dark conditions.

For engineers reviewing the TSMP98100 datasheet, TSMP98100 pinout, TSMP98100 application, or TSMP98100 equivalent, key selection considerations include its AC-coupled 30–60 kHz response, ±45° horizontal directivity, AGC-enabled ambient noise suppression, 0.45 mA typical supply current at 3.3 V, and leaded Minicast package compatibility with standard IR receiver design practices.

Technical Context

The TSMP98100 implements an integrated analog signal chain: IR light is detected by a PIN diode, amplified and AC-coupled through internal preamplifier stages, then conditioned by automatic gain control (AGC) to maintain consistent output amplitude across varying ambient light and signal strength. Its bandpass response is centered at 38 kHz with functional support across 30–60 kHz carrier frequencies.

Output is delivered as a demodulated carrier-out signal (pin 1), referenced to GND (pin 2) and powered from VS (pin 3). The device uses epoxy packaging optimized as an IR-pass/visible-light-blocking filter, and features improved shielding against electrical field disturbance - critical for reliable operation in noisy consumer electronics environments.

Key Specifications

Pinout & Package

TSMP98100 uses a 3-pin leaded Minicast package (5.0 mm × 6.95 mm × 4.8 mm) with gull-wing leads and integrated IR-filtering epoxy lens. Mounting is through-hole compatible.

FAQ

What is the primary function of the TSMP98100?

The TSMP98100 is an integrated infrared sensor module that detects and demodulates 38 kHz modulated IR signals from remote controls. It combines a PIN photodiode and preamplifier in one package, delivering a carrier-out output signal. This makes the TSMP98100 ideal for applications like IR repeaters and code-learning modules where preservation of carrier timing is essential - unlike standard demodulated-output receivers.

Does the TSMP98100 require external components to operate?

The TSMP98100 operates with only a supply decoupling capacitor (e.g., 1 µF) and optional pull-up resistor depending on load. Its internal AGC, bandpass filtering, and IR-optimized epoxy lens eliminate the need for external amplifiers, filters, or shielding. The recommended repeater circuit adds a 100 Ω series resistor and 680 Ω pull-down to limit output swing - but this is application-specific, not mandatory for basic detection.

What is the significance of the "carrier out" output on the TSMP98100?

The carrier-out output (pin 1) of the TSMP98100 preserves the original 38 kHz carrier envelope rather than providing a fully demodulated logic signal. This enables use cases such as IR repeater buffering and precise IR code learning, where timing fidelity of individual carrier cycles matters. Standard IR receivers output only a cleaned digital waveform - the TSMP98100 retains the analog-like carrier structure for downstream processing.

Can the TSMP98100 be used in automotive applications?

No, the TSMP98100 has not been qualified to any automotive-grade specification (e.g., AEC-Q200). Its operating temperature range is -25 °C to +85 °C, and it lacks automotive-specific reliability testing, qualification documentation, or part numbering suffixes indicating automotive compliance. For automotive IR sensing, Vishay offers separately qualified parts such as the TSSP series with AEC-Q200 certification - the TSMP98100 is intended for consumer and industrial indoor use only.

How does the TSMP98100 handle ambient light interference?

The TSMP98100 mitigates ambient light using dual mechanisms: its epoxy package acts as an optical IR-pass/visible-light-blocking filter, and its internal automatic gain control (AGC) dynamically adjusts amplification to suppress noise from sunlight or artificial lighting. Electrical field disturbance is further reduced by improved internal shielding. Test data shows stable operation even at 40 klx sunlight illumination, with supply current rising only to 0.45 mA - confirming robust ambient resilience without external compensation.
