Product details
Overview
TLHR4400-MS12Z from Vishay Semiconductors is a red light-emitting diode (LED) in a 3 mm tinted diffused plastic package (T-1), delivering 1.6–13 mcd luminous intensity at 10 mA, with dominant wavelength 612–625 nm, forward voltage 2–3 V at 20 mA, and ±30° viewing angle. It serves as an on/off indicator or status light in industrial control panels and instrumentation.
For engineers reviewing the TLHR4400-MS12Z datasheet, TLHR4400-MS12Z pinout, TLHR4400-MS12Z application, or TLHR4400-MS12Z equivalent, this page provides verified optical, electrical, and mechanical specifications, packaging orientation (cathode-first tape feed), absolute maximum ratings, and real-world use context for reliable visual indication design.
Technical Context
The TLHR4400-MS12Z is a GaAsP-on-GaP heterostructure LED optimized for DC and pulsed operation up to 1 A surge current (10 μs), with thermal resistance of 400 K/W and junction temperature limit of 100 °C. Its 3 mm diffused lens enables high on-off contrast and uniform illumination across ±30° half-intensity angle.
Rated for -40 to +100 °C operating temperature and compatible with standard reflow and hand-soldering (260 °C, 5 s), it uses ammopack tape with MS orientation code indicating cathode-first feed direction and 25.5 mm tape width per Vishay specification 948667-4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 1.6–13 mcd at 10 mA - defines visible brightness level under standard test conditions for consistent human-perceived indication |
| Dominant wavelength | 612–625 nm - ensures standardized red color output suitable for status differentiation in multi-color interfaces |
| Forward voltage | 2–3 V at 20 mA - determines series resistor selection and power budget for 3.3 V or 5 V logic-driven indicator circuits |
| Viewing angle | ±30° half-intensity - provides wide, uniform visibility without hotspots, ideal for front-panel indicators viewed from multiple angles |
| Absolute max forward current | 30 mA DC / 1 A surge (10 μs) - supports both steady-state and brief pulse-driven applications like blinking or strobing |
| Reverse voltage rating | 6 V - sets minimum reverse-bias protection requirement when used in AC-coupled or bidirectional drive configurations |
| Junction-to-ambient thermal resistance | 400 K/W - informs derating curves for ambient temperatures above 60 °C and validates suitability for sealed enclosures |
Pinout & Package
TLHR4400-MS12Z uses a standard 2-pin Ø3 mm (T-1) radial lead package with cathode-indicating flat edge and cathode-first tape orientation (MS code). Leads are tinned copper alloy, 0.5 mm diameter, 2.54 mm pitch, 4.4 mm length, and 3.4 mm body height per drawing 6.544-5255.01-4.
| 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 | Connected to ground or low-side switch; MS tape orientation confirms cathode feeds first into pick-and-place equipment |
Key Features
| Feature | Design Value |
|---|---|
| Standard T-1 (Ø3 mm) package | Ensures compatibility with legacy PCB footprints, panel cutouts, and automated assembly tooling across decades of industrial designs |
| Wide ±30° viewing angle | Eliminates need for secondary optics or reflectors in status-light applications, reducing BOM count and mechanical complexity |
| Luminous intensity binning | Guarantees IVmin/IVmax ≤ 0.5 within each bag - enables consistent brightness matching across multiple units in same assembly |
| Tinted diffused lens | Provides high on-off contrast and eliminates glare, critical for readability in brightly lit or variable ambient lighting environments |
| DC and high peak current capability | Supports direct microcontroller GPIO driving (with resistor) and high-duty-cycle PWM dimming without degradation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHR4400-AS12Z | Same optical/electrical specs; AS12Z denotes anode-first tape feed vs. MS12Z's cathode-first feed | Requires PCB footprint and pick-and-place program adjustment for lead polarity sequence | Select TLHR4400-AS12Z only if existing SMT line is configured for anode-leading tape reels |
| TLHR4401-MS12Z | Higher luminous intensity (2.5–14 mcd vs. 1.6–13 mcd); otherwise identical package, wavelength, and voltage | Better suited for applications requiring higher ambient light rejection or longer viewing distances | Choose TLHR4401-MS12Z when >13 mcd typical output is needed without changing layout or drive circuitry |
Compared with TLHR4400-MS12Z, TLHR4400-AS12Z differs only in tape orientation-no electrical or optical change-while TLHR4401-MS12Z offers +0.9 mcd min intensity at same test current, enabling improved visibility in bright environments without altering thermal or drive design.

FAQ
What is the exact package type and lead configuration of TLHR4400-MS12Z?
TLHR4400-MS12Z uses a standard Ø3 mm (T-1) radial lead package with two tinned copper alloy leads spaced 2.54 mm apart. The anode is the longer lead; the cathode is identified by the flat edge on the lens housing and feeds first in MS-coded tape per Vishay drawing 6.544-5255.01-4.
Does TLHR4400-MS12Z require external current limiting, and what resistor value is recommended for 5 V operation?
Yes, TLHR4400-MS12Z requires a series current-limiting resistor. For 5 V supply and 20 mA target current, use a 150 Ω resistor (VF = 2–3 V → R = (5 − 2.5)/0.02 = 125 Ω; 150 Ω provides margin). Derate power dissipation per ambient temperature using the datasheet's Fig. 1 curve.
Is TLHR4400-MS12Z RoHS-compliant and halogen-free?
Yes, TLHR4400-MS12Z complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard documented at www.vishay.com/doc?99912. Full compliance data is available in the official material declaration for document number 83006.
Can TLHR4400-MS12Z be driven directly from a 3.3 V microcontroller GPIO pin?
Yes, TLHR4400-MS12Z can be driven directly from a 3.3 V GPIO if current is limited to ≤10 mA (e.g., using 330 Ω resistor). Forward voltage is 2–3 V at 20 mA, so at 10 mA it drops to ~1.9 V, ensuring sufficient headroom. Confirm MCU pin sink/source capability meets 10 mA requirement.
What does the "MS12Z" suffix indicate in TLHR4400-MS12Z?
The "MS12Z" suffix specifies tape packaging: "MS" = cathode-first feed direction and 25.5 mm tape width; "12" = standard carrier tape per EIA-481; "Z" = ammopack (bulk reel) format. This ensures correct orientation during automated placement and distinguishes it from AS-coded (anode-first) variants.
