Product details
Overview
TLHK4200 from Vishay Semiconductors is a high-intensity red AlInGaP LED in a standard Ø3 mm (T-1) tinted non-diffused package, delivering 25–100 mcd luminous intensity at 10 mA, with dominant wavelength of 630 nm, forward voltage of 1.9–2.6 V at 20 mA, and ±22° viewing angle-designed for status indication and legend lighting in industrial control panels.
For engineers reviewing the TLHK4200 datasheet, TLHK4200 pinout, TLHK4200 application, or TLHK4200 equivalent, key selection criteria include luminous intensity binning (Group T–Z), narrow viewing angle for directional visibility, DC/high-peak-current capability (30 mA DC, 100 mA surge), thermal resistance (400 K/W), and compatibility with through-hole PCB assembly using standard 2.54 mm lead spacing.
Technical Context
This device uses AlInGaP-on-GaAs heterostructure technology to achieve high radiant efficiency in the red spectrum. Its non-diffused lens and ±22° half-intensity angle concentrate output for high on-axis brightness without secondary optics.
The TLHK4200 operates across –40 °C to +100 °C ambient temperature and supports both continuous DC drive (≤30 mA) and pulsed operation (e.g., 25 ms pulses for luminous intensity testing). Junction-to-ambient thermal resistance is fixed at 400 K/W due to its molded plastic package and internal leadframe design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 25–100 mcd at 10 mA - defines minimum/typical on-state visibility under standard test conditions |
| Dominant wavelength | 630 nm - specifies spectral peak for red color matching in indicator applications |
| Viewing angle | ±22° - enables focused beam for discrete status feedback without light bleed |
| Forward voltage | 1.9–2.6 V at 20 mA - determines series resistor value for constant-current biasing |
| DC forward current | 30 mA max at ≤60 °C - sets continuous drive limit for thermal reliability |
| Junction temperature | 100 °C max - constrains PCB layout and heatsinking for long-term lumen maintenance |
| Thermal resistance | 400 K/W - quantifies self-heating under load; requires derating above 60 °C ambient |
Pinout & Package
Package: Ø3 mm (T-1) radial-leaded plastic package with cathode-indicating flat side and 2.54 mm lead pitch; leads are tin-plated copper alloy, compatible with wave and hand soldering (260 °C, 5 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connected to current-limiting resistor and supply rail; polarity must be observed to avoid reverse breakdown |
| Cathode (shorter lead / flat side) | Negative terminal | Common return path; flat edge on package body identifies this terminal for automated placement |
Key Features
| Feature | Design Value |
|---|---|
| AlInGaP-on-GaAs chip technology | Delivers stable red emission with low wavelength shift over temperature vs. older GaAsP LEDs |
| Luminous intensity binning (Groups T–Z) | Enables consistent visual appearance across assemblies without manual sorting |
| Non-diffused clear lens | Preserves angular intensity profile for precise optical targeting in panel indicators |
| Standard T-1 mechanical footprint | Ensures drop-in replacement in legacy 3 mm LED sockets and wave-solder tooling |
| High surge current tolerance (100 mA, 10 μs) | Supports multiplexed or PWM-driven displays without external protection circuitry |
Applications
| Status Indicator | Legend Illumination |
|---|---|
Use Scenario: Front-panel power-on or fault condition signaling on industrial HMIs and PLC modules. IC Role / Device Role / Timing Role: Discrete visible-light emitter providing unambiguous binary state feedback.

Use Value: Stable 630 nm output matches human photopic response peak for optimal perceived brightness. | Use Scenario: Service-mode status flag on telecom line cards or server PSUs during field diagnostics. IC Role / Device Role / Timing Role: Infrequent-use indicator requiring long-term lumen retention and wide temperature operation. Use Value: –40 °C to +100 °C operating range supports deployment in uncontrolled environments like outdoor cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kingbright AML-303RSGD | Same Ø3 mm package, but diffused lens; 15–70 mcd at 20 mA; 625 nm dominant wavelength | Wider viewing angle (±35°) sacrifices on-axis intensity for broader coverage | Select when uniform panel illumination is prioritized over discrete point visibility |
| Lumex SSL-LX3033ID | Ø3 mm package, non-diffused, 30–120 mcd at 10 mA, 625 nm, 2.0–2.4 V VF | Higher min. intensity and tighter VF range; RoHS-compliant materials only | Prefer when stricter luminance consistency or environmental compliance drives BOM decisions |
Compared with TLHK4200, AML-303RSGD trades intensity for wider viewing, while SSL-LX3033ID offers higher minimum brightness and tighter electrical tolerances-both require verification of binning group availability and thermal derating curves for target ambient conditions.

FAQ
What is the maximum continuous forward current rating for TLHK4200?
The TLHK4200 has a maximum DC forward current of 30 mA when ambient temperature is ≤60 °C. Above that temperature, current must be linearly derated per the datasheet curve. Exceeding this limit risks accelerated lumen depreciation and junction overheating. Always verify thermal performance in the final PCB layout before finalizing the TLHK4200 drive circuit.
Does TLHK4200 require a current-limiting resistor in series?
Yes, TLHK4200 requires an external current-limiting resistor when driven from a constant-voltage source. With a forward voltage range of 1.9–2.6 V at 20 mA and typical supply rails of 3.3 V or 5 V, the resistor value must be calculated to maintain current within the 10–30 mA operating window. The TLHK4200 does not contain integrated current regulation.
How is luminous intensity binned for TLHK4200, and what does Group 'V' mean?
TLHK4200 is categorized into luminous intensity groups T–Z per the datasheet table, where Group V specifies 63–125 mcd at 10 mA. Each shipping bag contains LEDs from only one intensity group-no mixing-and Group V provides mid-to-high brightness suitable for applications needing reliable visibility without excessive power draw. The TLHK4200 order code does not encode group; binning is assigned at shipment.
Can TLHK4200 be used in pulsed operation, and what are the limits?
Yes, TLHK4200 supports pulsed operation with a surge forward current of 100 mA for pulse widths ≤10 μs. For longer pulses (e.g., 25 ms used in luminous intensity testing), average current must remain within DC ratings. Duty cycle and thermal mass of the PCB determine safe repetition rates. Always reference the TLHK4200 transient thermal curves before designing high-frequency PWM drive schemes.
What is the significance of the ±22° angle of half intensity for TLHK4200?
The ±22° angle of half intensity means luminous intensity drops to 50% of its on-axis value at 22° off-center-defining a narrow, directional beam. This allows precise optical alignment in indicator housings and minimizes crosstalk between adjacent LEDs on dense panels. The TLHK4200's non-diffused lens preserves this angular profile, making it unsuitable for wide-area backlighting but ideal for discrete status signaling.
