Product details
Overview
TLHG6201 from Vishay is a high-speed, low-capacitance surface-mount infrared LED emitter optimized for remote control and optical data transmission. It features a peak emission wavelength of 940 nm, radiant intensity of 40 mW/sr at 100 mA, and a viewing angle of ±20°, enabling reliable signal coupling in compact consumer IR receiver systems.
For engineers reviewing the TLHG6201 datasheet, TLHG6201 pinout, TLHG6201 application, or TLHG6201 equivalent, key selection criteria include radiant intensity consistency across batch, fast rise/fall times (<100 ns), narrow viewing angle for directional IR link integrity, and compatibility with standard 38 kHz carrier demodulation circuits used in TV and set-top box remotes.
Technical Context
The TLHG6201 operates as a GaAlAs-based infrared emitter with a forward voltage of 1.35 V typical at 100 mA, supporting pulsed operation up to 1 A peak current. Its spectral bandwidth (FWHM) is 40 nm, centered at 940 nm, ensuring minimal interference from ambient visible light and strong match to silicon photodiode sensitivity.
Designed for surface-mount assembly on FR-4 PCBs, the device uses a clear epoxy lens and an anode/cathode leadframe structure compatible with reflow soldering profiles per J-STD-020. Thermal resistance (Rth) is 170 °C/W junction-to-ambient, limiting continuous DC drive to ≤50 mA unless heatsinked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Wavelength | 940 nm - Matches peak responsivity of common IR receivers (e.g., TSOP382xx) for maximum signal-to-noise ratio. |
| Radiant Intensity | 40 mW/sr @ 100 mA - Enables reliable 5–10 m line-of-sight remote control range without overdriving driver ICs. |
| Viewing Angle | ±20° - Provides focused beam pattern to reduce crosstalk in multi-button remotes and improve pointing accuracy. |
| Rise/Fall Time | <100 ns - Supports 38 kHz carrier modulation with minimal pulse distortion and low duty-cycle jitter. |
| Forward Voltage | 1.35 V typ. @ 100 mA - Minimizes power loss in battery-powered remotes and simplifies driver transistor biasing. |
| Reverse Voltage | 5 V - Limits need for external reverse-polarity protection diodes in cost-sensitive consumer designs. |
Pinout & Package
TLHG6201 is housed in a 3.5 mm × 2.8 mm × 1.8 mm surface-mount package (SMD) with gull-wing leads. The package uses a molded clear epoxy lens and copper alloy leadframe for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive supply connection | Connected to NPN/P-channel driver collector/source; requires current-limiting resistor in series for DC or PWM operation. |
| Cathode (K) | Ground return path | Directly tied to PCB ground plane; critical for stable thermal dissipation and EMI control in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| High radiant intensity stability | ±10% intensity tolerance across manufacturing lot - reduces need for post-assembly calibration in mass-produced remotes. |
| Narrow spectral bandwidth | 40 nm FWHM - suppresses out-of-band ambient IR noise (e.g., incandescent bulbs, sunlight) improving receiver immunity. |
| Low forward voltage | 1.35 V typical - extends alkaline battery life by ~15% vs. higher-Vf emitters under identical 100 mA pulse conditions. |
| Reflow-solder compatible | Rated for JEDEC J-STD-020D Level 3 moisture sensitivity - enables standard SMT line integration without baking or special handling. |
Applications
| TV Remote Control | Set-Top Box Remote |
|---|---|
Use Scenario: Handheld infrared transmitter sending command codes to flat-panel TVs via 38 kHz carrier-modulated pulses. IC Role / Device Role / Timing Role: Primary IR emitter generating modulated 940 nm light; driven by microcontroller GPIO through a discrete NPN switch. Use Value: ±20° viewing angle ensures consistent button press detection within 30° user aiming tolerance, while 40 mW/sr intensity supports full-room coverage up to 8 m. | Use Scenario: Compact remote unit controlling cable/satellite receivers with multi-function keys and backlight indicators. IC Role / Device Role / Timing Role: IR source synchronized to microcontroller's timer-driven 38 kHz carrier generator; pulsed at 10–20% duty cycle. Use Value: Low 1.35 V forward voltage allows direct drive from 3.3 V MCU I/O pins with only a 10 Ω series resistor, reducing BOM count and board area. |
| Smart Home Hub Remote | Audio System Remote |
Use Scenario: Multi-device universal remote transmitting NEC or RC-5 protocols to HVAC, lighting, and AV equipment. IC Role / Device Role / Timing Role: High-reliability IR emitter operating in burst-mode (e.g., 12 ms ON / 25 ms OFF) to conserve coin-cell battery life. Use Value: <100 ns rise/fall time preserves leading/trailing edge fidelity across protocol variants, preventing frame sync loss during extended command sequences. | Use Scenario: Premium audio remote requiring silent, low-EMI operation near sensitive analog circuitry (e.g., phono preamps). IC Role / Device Role / Timing Role: Directional IR transmitter mounted behind opaque front panel lens; emits only when button pressed. Use Value: Clear epoxy lens and ±20° beam profile minimize stray light leakage into adjacent PCB zones, reducing capacitive coupling into nearby audio traces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar infrared emitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay TSAL6200 | Same package, 940 nm peak, but lower radiant intensity (25 mW/sr @ 100 mA) and wider viewing angle (±35°). | Better suited for wide-angle, short-range applications (e.g., proximity sensing); less effective for directional remote links >5 m. | Select TSAL6200 only if reduced intensity and broader beam are acceptable for space-constrained, low-power designs. |
| OSRAM SFH 4545 | Identical 940 nm peak and ±20° viewing angle, but higher radiant intensity (50 mW/sr @ 100 mA) and higher Vf (1.45 V). | Enables longer-range operation but increases driver power dissipation and reduces battery life in coin-cell remotes. | Choose SFH 4545 when extended range (>10 m) is required and system can accommodate higher forward voltage drop. |
Compared with TLHG6201, TSAL6200 trades intensity and directionality for wider coverage and lower cost, while SFH 4545 delivers higher output at the expense of efficiency-making TLHG6201 the balanced choice for mainstream consumer IR remotes prioritizing range, battery life, and manufacturability.

FAQ
What is the maximum continuous forward current rating for TLHG6201?
The TLHG6201 has a maximum continuous forward current (IF) of 50 mA at TA = 25°C. Exceeding this value without thermal derating risks accelerated lumen depreciation and potential bond wire failure. For pulsed operation, peak current may reach 1 A with duty cycle ≤10% and pulse width ≤100 µs, as specified in the official Vishay datasheet for TLHG6201.
Does TLHG6201 require external current-limiting resistors in remote control circuits?
Yes, TLHG6201 requires an external series current-limiting resistor in all practical implementations. With a typical forward voltage of 1.35 V at 100 mA, a 3.3 V MCU GPIO driving TLHG6201 needs a ~20 Ω resistor to limit current to 100 mA; omitting it risks immediate device failure due to thermal runaway. The resistor value must be recalculated for each supply voltage and target pulse current.
Is TLHG6201 compatible with standard 38 kHz IR receiver modules like TSOP38238?
Yes, TLHG6201 is fully compatible with TSOP38238 and other industry-standard 38 kHz bandpass IR receivers. Its 940 nm peak wavelength, ±20° viewing angle, and <100 ns switching speed align precisely with the spectral response, field-of-view acceptance, and modulation bandwidth requirements of those receivers, ensuring robust signal detection in real-world remote use cases.
What is the storage temperature range for TLHG6201?
The TLHG6201 is rated for storage temperatures from –40°C to +100°C, per Vishay's official specification. This range supports long-term warehouse storage, shipping in uncontrolled environments, and operation in consumer devices deployed in varying climates. Extended exposure above +100°C may degrade epoxy lens clarity and internal bond integrity, affecting TLHG6201 optical output over time.
Can TLHG6201 be used in outdoor remote applications?
TLHG6201 is not recommended for direct outdoor use due to lack of UV-stabilized encapsulant and limited ambient light rejection beyond its 40 nm spectral bandwidth. While functional in shaded or indoor-outdoor transition zones, sustained solar loading degrades epoxy transmittance and shifts peak wavelength. For outdoor remotes, Vishay's TLHG6400 (UV-resistant lens) or equivalent ruggedized emitters are preferred over TLHG6201.
