Product details
Overview
TLHG4405-MS12 from Vishay Semiconductors is a green high-efficiency LED in a 3 mm tinted diffused plastic package (T-1), delivering 6.3–15 mcd luminous intensity at 10 mA, with dominant wavelength 562–575 nm and ±30° viewing angle-designed for status indication and legend lighting in industrial control panels.
For engineers reviewing the TLHG4405-MS12 datasheet, TLHG4405-MS12 pinout, TLHG4405-MS12 application, or TLHG4405-MS12 equivalent, key selection criteria include luminous intensity binning (Q group), forward voltage range (2.4–3.0 V at 20 mA), reverse voltage rating (6 V), and compatibility with DC or pulsed drive up to 1 A surge current.
Technical Context
This device uses GaP-on-GaP epitaxial technology to achieve stable green emission with tight wavelength grouping (562–575 nm dominant) and high on-off contrast enabled by its wide ±30° half-intensity angle and diffused lens. It operates across –40 °C to +100 °C ambient temperature with thermal resistance of 400 K/W.
The TLHG4405-MS12 is categorized in luminous intensity group Q (6.3–12.5 mcd) and wavelength group 3–8 (562–575 nm), ensuring visual uniformity when assembled in arrays. Its 3 mm T-1 package supports standard through-hole mounting and automated tape-and-reel handling (MS orientation: cathode before anode).
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 under typical panel lighting |
| Dominant wavelength | 562–575 nm - ensures consistent green color perception across production lots and viewing angles |
| Forward voltage | 2.4–3.0 V at 20 mA - determines series resistor value and power dissipation in constant-current drive circuits |
| Viewing angle | ±30° half-intensity - provides wide visibility without hot-spotting, suitable for front-panel indicators viewed from multiple angles |
| Absolute max forward current | 30 mA DC / 1 A surge (10 µs) - sets safe operating limits for continuous vs. pulsed operation in microcontroller GPIO-driven applications |
| Reverse voltage | 6 V - defines minimum protection diode or layout clearance needed against accidental reverse bias |
| Junction temperature | 100 °C max - constrains thermal design when mounted near heat sources or in sealed enclosures |
Pinout & Package
TLHG4405-MS12 uses a standard 2-pin Ø3 mm (T-1) radial lead package with cathode-indicating flat side and MS tape orientation (cathode lead first). Leads are tinned copper alloy, compatible with wave and reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connected to current source or MCU output; requires current-limiting resistor or constant-current driver |
| Cathode (shorter lead, flat side) | Negative terminal | Reference node for driving circuit; MS tape orientation confirms cathode lead enters feeder first |
Key Features
| Feature | Design Value |
|---|---|
| Standard Ø3 mm T-1 package | Enables drop-in replacement in legacy indicator layouts and compatibility with existing pick-and-place tooling |
| Luminous intensity binning (Q group) | Guarantees 6.3–12.5 mcd consistency within each reel, reducing post-assembly brightness sorting effort |
| Wavelength grouping (562–575 nm) | Ensures uniform green hue across multi-LED arrays without visible color shift between units |
| Wide ±30° viewing angle | Supports readability from oblique angles in control cabinets and operator interfaces without optical lenses |
| DC and high peak current capability | Allows direct GPIO driving (with resistor) or PWM dimming up to 1 kHz without degradation |
Applications
| Status lights | Off / on indicator |
|---|---|
Use Scenario: Front-panel LED on industrial PLC I/O module indicating channel activity. IC Role / Device Role / Timing Role: Visual status emitter driven by microcontroller GPIO with current-limiting resistor. Use Value: High on-off contrast and ±30° viewing angle ensure clear visibility across cabinet doors and at varied operator positions. |
Use Scenario: Power-on indicator on medical device power supply unit. IC Role / Device Role / Timing Role: Steady-state DC-driven green emitter confirming system readiness. Use Value: Tight 562–575 nm wavelength binning prevents hue mismatch with adjacent red/yellow indicators. |
| Legend light | Maintenance light |
Use Scenario: Backlighting engraved labels on HVAC control panel overlays. IC Role / Device Role / Timing Role: Low-current (10 mA) diffused emitter placed behind translucent legend area. Use Value: Tinted diffused lens delivers even illumination without glare or hot spots under 24/7 operation. |
Use Scenario: Service-mode indicator inside telecom rack-mounted chassis. IC Role / Device Role / Timing Role: Pulse-driven (10 µs, 1 A) emitter activated during diagnostic mode. Use Value: Rated 1 A surge current enables brief high-brightness pulses for technician visibility in dark enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar green LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHG4405-AS12Z | Same luminous intensity (Q group) and wavelength (562–575 nm), but AS12Z tape orientation places anode first. | Requires PCB footprint and feeder setup revision if replacing TLHG4405-MS12 in automated assembly. | Select only if anode-first tape handling is already standardized in your SMT line. |
| TLHG4401-MS12 | Lower luminous intensity (4–14 mcd, N group); otherwise identical package, wavelength, and electrical specs. | Suitable where reduced brightness lowers power consumption or mitigates glare in low-light environments. | Choose when 4–14 mcd meets visibility requirements and cost optimization is prioritized over maximum intensity. |
Compared with TLHG4405-MS12, TLHG4405-AS12Z offers identical optical performance but demands tape orientation revalidation, while TLHG4401-MS12 trades 30% lower typical intensity for lower cost and power draw-making it appropriate for non-critical or battery-powered indicators.

FAQ
What is the luminous intensity range of TLHG4405-MS12 at 10 mA?
The TLHG4405-MS12 delivers a luminous intensity of 6.3–15 mcd at 10 mA, corresponding to intensity group Q per Vishay's classification. This range ensures consistent brightness across units shipped in the same reel, supporting uniform appearance in multi-LED installations without manual sorting.
Does TLHG4405-MS12 have a specified dominant wavelength?
Yes, TLHG4405-MS12 has a dominant wavelength range of 562–575 nm, placing it in green wavelength groups 3–8. This specification guarantees color consistency across production batches and enables reliable matching with other green LEDs in multi-color indicator systems.
What does the "MS12" suffix indicate in TLHG4405-MS12?
The "MS12" suffix denotes tape-and-reel packaging with cathode-first orientation (MS) and standard 2.54 mm pitch (12), compliant with EIA-481-D. This ensures compatibility with automated placement equipment configured for cathode-leading feed, distinguishing it from AS12Z (anode-first) variants.
Can TLHG4405-MS12 be driven directly from a 3.3 V microcontroller GPIO?
Yes, TLHG4405-MS12 can be driven from a 3.3 V GPIO using a series current-limiting resistor. With a forward voltage of 2.4–3.0 V at 20 mA, a 100 Ω resistor yields ~10–13 mA drive-within rated limits and sufficient for most status indication needs without external drivers.
What is the maximum allowable reverse voltage for TLHG4405-MS12?
The absolute maximum reverse voltage for TLHG4405-MS12 is 6 V. Exceeding this risks junction breakdown; designs with potential reverse polarity (e.g., AC-coupled signals or shared return paths) must include protection diodes or ensure strict polarity control in layout and cabling.
