Product details
Overview
QTLP630C2TR from Fairchild Semiconductor is a surface-mount AlGaAs red LED lamp in 0805 package, delivering 10 mcd typical luminous intensity at 20 mA, 2.4 V typical forward voltage, and 645 nm dominant wavelength with ±15 nm tolerance, optimized for keypad, push-button, and LCD backlighting in compact consumer and industrial interfaces.
For engineers reviewing the QTLP630C2TR datasheet, pinout, applications, or equivalent options, key selection criteria include its 140° viewing angle, moisture-proof construction, 30 mA continuous forward current rating, and cathode-marked polarity for reliable SMT assembly and optical uniformity in space-constrained illumination designs.
Technical Context
This AlGaAs red LED operates with a peak emission at 660 nm and dominant wavelength at 645 nm, enabling high-visibility signaling under ambient light. Its 140° Lambertian radiation pattern ensures wide-angle uniform illumination without secondary optics.
The device supports IR reflow soldering up to 240°C for 5 seconds and is rated for -40°C to +85°C operation. It uses water-clear epoxy encapsulation and is supplied on 8 mm tape, 2,000 units per 7-inch reel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 10 mcd typical at 20 mA - delivers visible brightness for indicator use at low drive current |
| Forward Voltage | 2.4 V typical at 20 mA - compatible with 3.3 V and 5 V logic-supplied current-limiting resistor networks |
| Dominant Wavelength | 645 nm - AlGaAs red spectral output optimized for human eye sensitivity and color coding |
| Viewing Angle | 140° - enables broad, even illumination across buttons or LCD edges without lensing |
| Continuous Forward Current | 30 mA - supports sustained operation in always-on status indicators and backlight segments |
| Package Size | 2.0 × 1.25 × 1.1 mm - fits standard 0805 footprint, enabling high-density PCB layout |
Pinout & Package
QTLP630C2TR uses a 2-terminal surface-mount package with cathode polarity marked by a notch or bar on the top surface. The device has no internal circuitry-only anode and cathode terminals for DC biasing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked side) | Positive terminal | Connects to current-limiting resistor and supply rail; requires external series resistance for 20–30 mA operation |
| Cathode (marked side) | Negative terminal | Identified by polarity mark; connects to ground or low-side switch; reverse connection blocks conduction |
Key Features
| Feature | Design Value |
|---|---|
| Wide viewing angle | 140° full-width half-maximum radiation pattern ensures consistent brightness across ±70° viewing cone |
| Water-clear optics | Uncoated epoxy lens maximizes luminous transmission and preserves spectral purity for accurate red color rendering |
| Moisture-proof packaging | Hermetically sealed construction meets JEDEC MSL Level 1 - no dry-pack or bake-out required before SMT |
| Standard 0805 footprint | 2.0 × 1.25 mm land pattern aligns with IPC-7351B generic 0805 definition, enabling drop-in replacement in existing layouts |
Applications
| Keypad Backlighting | Push-Button Indicator |
|---|---|
Use Scenario: Illuminating membrane or mechanical keypad overlays in handheld medical devices and industrial HMIs. IC Role / Device Role / Timing Role: Discrete light source driven directly by GPIO or constant-current LED driver IC. Use Value: 140° viewing angle ensures uniform keycap illumination without hotspots; 645 nm red provides high contrast against dark backgrounds. |
Use Scenario: Status indication on tactile push-buttons in test equipment and control panels. IC Role / Device Role / Timing Role: Standalone visual feedback element with no timing or logic function. Use Value: 10 mcd output at 20 mA enables clear visibility in both dim and moderately lit environments without excessive power draw. |
| LCD Edge Backlighting | Panel-Mount Status Light |
Use Scenario: Side-lit illumination for monochrome or segment LCDs in instrumentation and automotive clusters. IC Role / Device Role / Timing Role: Passive optical component placed along LCD edge; driven continuously or PWM-modulated. Use Value: AlGaAs red spectrum avoids UV degradation of light-guide materials; low 1.1 mm height clears tight bezel constraints. |
Use Scenario: Front-panel power-on or fault indicator on embedded controllers and power supplies. IC Role / Device Role / Timing Role: Directly biased discrete emitter; no integrated driver or intelligence. Use Value: Moisture-proof packaging ensures long-term reliability in non-hermetic enclosures; 30 mA rating supports robust overdrive margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Lite-On LTST-C191KFKT | 630 nm dominant wavelength, 12 mcd @ 20 mA, same 0805 package but with diffused lens | Slightly higher intensity but narrower 120° viewing angle; better for focused indication than wide-area backlighting | Prefer when higher brightness is needed and viewing cone can be narrower |
| Vishay TLHR5400 | 635 nm, 15 mcd @ 20 mA, 2.1 V VF, same cathode-marked 0805 package | Lower forward voltage reduces power loss in high-channel-count arrays; identical thermal and mounting behavior | Prefer when minimizing I²R losses across multiple LEDs or extending battery life in portable designs |
Compared with QTLP630C2TR, LTST-C191KFKT offers higher intensity but reduced angular coverage, while TLHR5400 lowers forward voltage for efficiency-critical arrays-neither is pin-compatible by datasheet claim, but both share identical 0805 land patterns and cathode-first orientation.

FAQ
What is the polarity configuration of QTLP630C2TR?
QTLP630C2TR uses cathode-anode polarity, with the cathode identified by a polarity mark (notch or bar) on the top surface. This matches the -2, -3, -4, and -B variants per Fairchild's documentation. Applying forward bias-positive to unmarked side, negative to marked side-enables conduction. Reverse connection blocks current flow and must be avoided during PCB layout and assembly.
What is the maximum continuous forward current for QTLP630C2TR?
The absolute maximum continuous forward current for QTLP630C2TR is 30 mA at TA = 25°C. Derating is required above 25°C ambient, with maximum allowable current dropping to approximately 20 mA at 60°C and 10 mA at 85°C per the published derating curve. Exceeding 30 mA risks accelerated lumen depreciation and junction overheating.
Does QTLP630C2TR require moisture sensitivity level (MSL) handling?
No-QTLP630C2TR is rated MSL Level 1 per JEDEC J-STD-020, meaning it has unlimited floor life and does not require dry packing, baking, or special handling prior to reflow. Its moisture-proof packaging and epoxy encapsulation eliminate humidity-induced popcorning risk during standard IR reflow profiles up to 240°C.
What is the recommended soldering profile for QTLP630C2TR?
The recommended IR reflow profile for QTLP630C2TR specifies preheating at ≤5°C/s to 120–150°C for 60–120 seconds, followed by a peak temperature of 240°C maximum for ≤5 seconds. Cooling rate must not exceed 5°C/s. This aligns with IPC/JEDEC J-STD-020 and avoids thermal stress on the epoxy lens or bond wires.
Can QTLP630C2TR be used in outdoor or high-humidity environments?
QTLP630C2TR's moisture-proof packaging and water-clear epoxy lens provide resistance to humidity ingress, making it suitable for indoor industrial enclosures and sealed consumer housings. However, it is not rated for direct outdoor exposure, UV resistance, or immersion-external conformal coating or secondary sealing is required for such environments.
