Product details
Overview
TLHR5400-AS12Z from Vishay Semiconductors is a red 5 mm tinted diffused LED with dominant wavelength 612–630 nm, luminous intensity 1.6–10 mcd at 10 mA, and forward voltage 2–3 V at 20 mA. It operates as a status or indicator light in industrial control panels and instrumentation interfaces requiring high on-off contrast and uniform visual appearance.
For engineers reviewing the TLHR5400-AS12Z datasheet, TLHR5400-AS12Z pinout, TLHR5400-AS12Z application, or TLHR5400-AS12Z equivalent, this device supports DC and pulsed operation up to 1 A surge current, delivers ±30° viewing angle, and ships in cathode-first tape (AS12) for automated SMT placement-key selection criteria for reliability-critical indicator designs.
Technical Context
This device is a GaAsP-on-GaP heterostructure LED optimized for visible red emission. Its optical design features a tinted diffused lens that enhances contrast while maintaining wide angular distribution. The 5 mm T-1¾ package includes mechanical stand-offs for consistent board clearance and solder joint integrity.
It complies with Vishay's luminous intensity binning (Group M: 1.6–3.2 mcd) and wavelength grouping standards, ensuring batch-to-batch visual uniformity. Absolute maximum ratings include 30 mA DC forward current, 6 V reverse voltage, and 100 °C junction temperature-enabling robust operation in industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Red, dominant wavelength 612–630 nm - ensures consistent human-visible signaling in status applications. |
| Luminous intensity | 1.6–10 mcd at 10 mA - falls in Vishay Group M binning, enabling matched brightness across assemblies. |
| Forward voltage | 2–3 V at 20 mA - compatible with standard 3.3 V or 5 V logic-level drive circuits without external regulation. |
| Viewing angle | ±30° half-intensity - provides wide visibility across panel surfaces without hot-spot glare. |
| Absolute max forward current | 30 mA continuous - supports sustained indicator operation with margin for thermal derating above 65 °C. |
| Surge current rating | 1 A for ≤10 μs - enables compatibility with pulse-driven multiplexed displays and low-duty-cycle signaling. |
| Junction-to-ambient thermal resistance | 350 K/W - defines thermal rise under steady-state bias; requires PCB copper area or airflow for >20 mA continuous use. |
Pinout & Package
TLHR5400-AS12Z uses a standard 5 mm T-1¾ radial-leaded plastic package with cathode lead exiting first in tape (AS12 orientation). The device has two terminals: anode and cathode, with no internal circuitry or polarity-sensitive markings beyond standard LED polarity conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal | Connected to current source or MCU GPIO via current-limiting resistor; forward bias initiates photon emission. |
| Cathode | Negative terminal | Connected to ground or sink driver; AS12 tape orientation ensures cathode leads tape feed direction for pick-and-place alignment. |
Key Features
| Feature | Design Value |
|---|---|
| Tinted diffused lens | Improves on-off contrast ratio by scattering emitted light uniformly, reducing glare and enhancing readability in ambient-lit environments. |
| Intensity and wavelength binning | Enables assembly of visually matched LEDs within same bag (IVmin/IVmax ≤ 0.5), eliminating post-production sorting for panel consistency. |
| Stand-off design | Provides mechanical clearance between LED body and PCB surface, minimizing thermal stress and improving solder joint reliability during reflow. |
| DC and high peak current capability | Supports both constant-current drive (e.g., 10–20 mA) and short-pulse operation (≤10 μs, 1 A), enabling multiplexed or strobed display architectures. |
Applications
| Status lights | Off / on indicator |
|---|---|
Use Scenario: Visual status indication on industrial PLC I/O modules and power supply front panels. IC Role / Device Role / Timing Role: Discrete red LED emitter providing binary operational state feedback. Use Value: High on-off contrast and ±30° viewing angle ensure legibility from multiple operator positions without backlighting. |
Use Scenario: Power-on confirmation and fault signaling in medical diagnostic equipment user interfaces. IC Role / Device Role / Timing Role: Standalone indicator element driven directly from microcontroller GPIO pins. Use Value: 2–3 V forward voltage aligns with 3.3 V system rails, eliminating need for level-shifting or external drivers. |
| Background illumination | Legend light |
Use Scenario: Edge-lit bezel lighting behind translucent membrane switch overlays in HVAC control panels. IC Role / Device Role / Timing Role: Low-power visible-light source positioned beneath diffuser films. Use Value: Tinted diffused package delivers uniform luminance without discrete hotspots, reducing visual fatigue during prolonged use. |
Use Scenario: Illumination of engraved legends on pushbutton actuators in factory floor machinery. IC Role / Device Role / Timing Role: Surface-mounted indicator aligned with legend cutouts for direct light transmission. Use Value: Group M intensity binning ensures consistent brightness across all buttons in multi-unit assemblies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHR5401 | Luminous intensity 4–12 mcd (Group N), otherwise identical optical/electrical specs and package. | Higher brightness suitable for outdoor-facing or high-ambient-light panels where TLHR5400-AS12Z may appear dim. | Select TLHR5401 when >3 mcd minimum intensity is required; verify optical path and viewing angle remain acceptable. |
| TLHR5405-KS21 | Luminous intensity 6.3–14 mcd (Group Q); KS21 denotes anode-first tape orientation vs. AS12Z's cathode-first. | Same brightness tier but reversed tape feed direction-requires adjustment in SMT feeder setup and reel loading. | Choose TLHR5405-KS21 only if anode-first tape is mandated by production line configuration; electrical performance is interchangeable. |
Compared with TLHR5400-AS12Z, TLHR5401 offers higher luminous output for demanding visibility conditions, while TLHR5405-KS21 provides equivalent brightness with reversed tape orientation-neither is pin-compatible (as LEDs have no pins), but both share identical footprint, thermal profile, and drive requirements.

FAQ
What is the luminous intensity range of TLHR5400-AS12Z at 10 mA?
The TLHR5400-AS12Z has a luminous intensity range of 1.6–10 mcd at 10 mA, corresponding to Vishay's Group M binning. This ensures brightness uniformity within each packaging unit (IVmin/IVmax ≤ 0.5), making TLHR5400-AS12Z suitable for applications requiring matched visual output across multiple units on a single PCB.
What does the "AS12Z" suffix indicate in TLHR5400-AS12Z?
The "AS12Z" suffix specifies tape orientation and packaging: "AS" denotes standard ammopack tape, "12" means cathode lead exits the tape first (critical for automated placement alignment), and "Z" indicates ammopack format (5 × 1000 units per carton). TLHR5400-AS12Z is not supplied in reel format.
Is TLHR5400-AS12Z suitable for pulsed operation?
Yes, TLHR5400-AS12Z supports pulsed operation with a surge forward current rating of 1 A for pulses ≤10 μs. Its GaAsP-on-GaP structure and thermal resistance of 350 K/W allow safe intermittent drive in multiplexed displays-provided average power remains within 100 mW and duty cycle limits are observed per Vishay's Fig. 7.
What is the dominant wavelength specification for TLHR5400-AS12Z?
The dominant wavelength of TLHR5400-AS12Z is specified as 612–630 nm at 10 mA, placing it in the deep red visible spectrum. This range is consistent across all TLHR540x red variants and enables predictable color matching in multi-LED arrays where spectral consistency affects perceived uniformity.
Does TLHR5400-AS12Z require current-limiting resistors in standard 5 V drive circuits?
Yes, TLHR5400-AS12Z requires an external current-limiting resistor when driven from a 5 V source. With a forward voltage of 2–3 V at 20 mA, a ~100 Ω resistor is typical to limit current to 20 mA; omitting this resistor risks exceeding the 30 mA absolute maximum DC rating and accelerating lumen depreciation in TLHR5400-AS12Z.
