Product details
Overview
TLHP4405 from Vishay Semiconductors is a red light-emitting diode (LED) in a 3 mm tinted diffused plastic package (T-1), designed for status indication and panel lighting. It delivers 6.3–15 mcd luminous intensity at 10 mA, with dominant wavelength 612–625 nm, ±30° viewing angle, and forward voltage 2–3 V at 20 mA.
For engineers reviewing the TLHP4405 datasheet, TLHP4405 pinout, TLHP4405 application, or TLHP4405 equivalent, this page provides verified optical, electrical, and mechanical specifications - including luminous intensity binning, wavelength grouping, thermal resistance (400 K/W), and absolute maximum ratings - to support indicator design, BOM validation, and visual consistency planning in industrial control panels and instrumentation.
Technical Context
The TLHP4405 uses GaAsP-on-GaP epitaxial technology to achieve stable red emission with high on-off contrast. Its ±30° half-intensity angle and tinted diffused lens ensure uniform illumination across wide viewing angles without hotspots.
Rated for DC and pulsed operation up to 1 A surge current (10 μs), it supports reliable indicator function under variable drive conditions. Thermal resistance of 400 K/W and operating temperature range of –40 °C to +100 °C enable use in demanding industrial ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 6.3–15 mcd at 10 mA - defines visible brightness level for human-readable status indication at standard drive current |
| Dominant wavelength | 612–625 nm - ensures consistent red hue within industry-standard color space for identification and safety compliance |
| Viewing angle | ±30° half-intensity - provides wide, even light distribution suitable for front-panel indicators viewed from multiple angles |
| Forward voltage | 2–3 V at 20 mA - determines series resistor value and power dissipation in simple DC drive circuits |
| Absolute max forward current | 30 mA DC - sets upper limit for continuous operation without degradation or accelerated aging |
| Junction-to-ambient thermal resistance | 400 K/W - quantifies self-heating under load; informs derating requirements above 60 °C ambient |
| Reverse voltage rating | 6 V - defines minimum protection needed against polarity reversal or transient back-EMF in panel wiring |
Pinout & Package
TLHP4405 is housed in a standard Ø3 mm (T-1) tinted diffused plastic package with axial leads. Cathode is identified by a flat edge on the lens housing and shorter lead; anode is longer lead. No internal circuitry - two-terminal passive device.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current source or series resistor; must be biased >2 V above cathode to emit light |
| Cathode (shorter lead, flat edge) | Negative terminal | Reference node for current return; polarity marking critical to prevent reverse breakdown at >6 V |
Key Features
| Feature | Design Value |
|---|---|
| Standard T-1 (Ø3 mm) package | Enables drop-in replacement in legacy 3 mm indicator sockets and PCB footprints without mechanical redesign |
| Luminous intensity binning (Group Q) | Guarantees IVmin/IVmax ≤ 0.5 within each bag - ensures uniform brightness across multiple units in same assembly |
| Tinted diffused lens | Eliminates glare and provides soft, homogeneous illumination ideal for legend and status lights |
| Wide ±30° viewing angle | Supports readability from off-axis positions typical in control cabinets and operator interfaces |
| GaAsP-on-GaP chip technology | Delivers stable red output with low wavelength drift over temperature and lifetime vs. AlInGaP alternatives |
Applications
| Status Indication | Panel Legend Lighting |
|---|---|
|
Use Scenario: Visual confirmation of power-on, fault, or mode state on industrial HMIs and machine control panels. IC Role / Device Role / Timing Role: Passive optical emitter - driven by microcontroller GPIO or discrete transistor switch. Use Value: High on-off contrast and wide viewing angle ensure immediate recognition by operators across cabinet doors and viewing distances up to 2 m. |
Use Scenario: Backlighting engraved or printed legends (e.g., "RUN", "STOP", "ALARM") on metal or plastic overlays. IC Role / Device Role / Timing Role: Steady-state DC-driven light source; no timing or modulation required. Use Value: Tinted diffused lens delivers even, non-glare illumination that enhances legibility without hotspots or shadowing. |
| Maintenance Indicator | Off/On Power Monitoring |
|
Use Scenario: Service access point indicators on field equipment (e.g., PLC modules, sensor transmitters) showing operational readiness. IC Role / Device Role / Timing Role: Low-power, long-life visual marker - operates continuously at 10 mA for >50,000 hours. Use Value: Luminous intensity binning (Group Q) ensures consistent appearance across batches during field replacement and service kit replenishment. |
Use Scenario: Primary power presence indicator on AC/DC power supplies, DIN-rail mounted converters, and embedded power modules. IC Role / Device Role / Timing Role: Directly connected via series resistor to regulated DC rail (e.g., 5 V, 12 V, 24 V). Use Value: Forward voltage tolerance (2–3 V) and 30 mA absolute max rating allow robust operation across input voltage tolerances and aging effects. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHR4405 | Identical optical specs (6.3–15 mcd, 612–625 nm, ±30°), same GaAsP-on-GaP die and T-1 package; differs only in part numbering suffix convention (no functional difference) | No difference - used interchangeably in Vishay's documentation and packaging; both meet identical luminance and wavelength binning standards | Select TLHR4405 if sourcing from distributors listing that variant; identical performance and fit. |
| TLHR4401 | Lower luminous intensity (2.5–14 mcd at 10 mA); same wavelength, viewing angle, and package; shares same absolute max ratings and thermal resistance | Suitable where reduced brightness suffices (e.g., low-ambient-light environments or battery-powered devices requiring lower current draw) | Choose TLHR4401 when brightness headroom is unnecessary and lower power consumption or cost optimization is prioritized. |
Compared with TLHP4405, TLHR4405 offers identical photometric and electrical behavior with no design impact, while TLHR4401 provides a lower-brightness alternative for power-sensitive or cost-constrained implementations - both maintain the same mechanical footprint and thermal profile.

FAQ
What is the luminous intensity range of TLHP4405 at 10 mA?
The TLHP4405 delivers a luminous intensity of 6.3–15 mcd at 10 mA, per Vishay's official datasheet (Document Number: 83006, Rev. 3.8). This places it in Group Q binning, ensuring consistent brightness across units shipped in the same bag - critical for uniform appearance in multi-LED panels and status arrays.
Does TLHP4405 have a diffused or clear lens?
TLHP4405 features a tinted diffused lens, as confirmed in the Vishay datasheet description: "High Efficiency LED in Ø 3 mm Tinted Diffused Package." The diffusion eliminates glare and provides soft, even illumination ideal for legend lighting and status indicators where harsh point sources would impair readability.
What is the forward voltage range for TLHP4405 at 20 mA?
The forward voltage of TLHP4405 is specified as 2–3 V at 20 mA, per the "OPTICAL AND ELECTRICAL CHARACTERISTICS" table in the Vishay datasheet. This range directly informs series resistor selection in constant-voltage drive circuits and confirms compatibility with common 3.3 V, 5 V, and 12 V supply rails when appropriately limited.
Is TLHP4405 RoHS-compliant and halogen-free?
Yes - TLHP4405 complies with RoHS Directive 2011/65/EU and is halogen-free, as stated in Vishay's material categorization documentation referenced in the datasheet (www.vishay.com/doc?99912). Compliance is verified per Vishay's standard material declarations and applies to all TLH.44.. series variants including TLHP4405.
What is the maximum allowable reverse voltage for TLHP4405?
The absolute maximum reverse voltage for TLHP4405 is 6 V, as defined in the "ABSOLUTE MAXIMUM RATINGS" section of the Vishay datasheet. Exceeding this value risks permanent junction damage; design best practice requires polarity protection (e.g., series diode or reverse-blocking FET) in applications with potential reverse bias events.
