Vishay Semiconductor Opto Division TLPH5600

Overview

TLPH5600 from Vishay Semiconductors is a 5 mm side-view red LED with dominant wavelength 612–625 nm, luminous intensity 0.63–3.5 mcd at 10 mA, and ±80° viewing angle-designed for front-panel status indication in industrial HMIs and consumer appliance displays.

For engineers reviewing the TLPH5600 datasheet, TLPH5600 pinout, TLPH5600 application, or TLPH5600 equivalent, key selection criteria include forward current rating (30 mA), thermal resistance (400 K/W), and GaAsP-on-GaP chip technology enabling stable red emission under DC/pulse operation across -40 to +100 °C ambient.

Technical Context

The TLPH5600 uses a GaAsP-on-GaP heterostructure emitting in the red spectrum (612–625 nm dominant, ~635 nm peak), with a tinted diffused lens optimized for uniform luminance and wide angular distribution. Its side-view package enables compact PCB mounting with light output directed parallel to the board surface.

Rated for 30 mA DC forward current and 100 mW power dissipation at ≤60 °C ambient, the device achieves junction-to-ambient thermal resistance of 400 K/W-enabling reliable operation without heatsinking in low-power indicator applications where thermal budget is constrained.

Key Specifications

Pinout & Package

TLPH5600 is housed in a standard 5 mm side-view plastic package with two axial leads: anode (longer lead) and cathode (shorter lead, flat side on housing). No polarity marking on lens; identification relies on lead length and housing flat.

FAQ

What is the dominant wavelength range of the TLPH5600?

The TLPH5600 has a dominant wavelength range of 612–625 nm, placing its output in the red portion of the visible spectrum. This range is measured at 10 mA forward current and ensures consistent color perception across production lots. The TLPH5600's GaAsP-on-GaP chip structure maintains this wavelength stability over temperature and aging, making TLPH5600 suitable for applications where red hue fidelity matters-such as safety-critical status indicators.

What is the maximum forward current rating for TLPH5600?

The TLPH5600 is rated for a maximum DC forward current of 30 mA at ambient temperatures ≤60 °C. Exceeding this current requires thermal derating per the datasheet's forward current vs. ambient temperature curve. This 30 mA rating distinguishes TLPH5600 from the TLPR5600 (20 mA), giving TLPH5600 greater drive headroom for brightness control or extended lifetime at lower currents. Always verify PCB copper area and airflow when operating TLPH5600 near its thermal limits.

Does TLPH5600 support pulse operation, and what are the limits?

Yes, TLPH5600 supports pulse operation with a surge forward current rating of 1 A for pulse widths ≤10 μs. Pulse operation enables higher instantaneous brightness without exceeding average power limits-useful for strobing or multiplexed displays. However, duty cycle and pulse repetition rate must be constrained to keep average power within 100 mW and junction temperature below 100 °C. The TLPH5600's 50 pF junction capacitance also supports fast switching in pulse-driven systems.

How is luminous intensity binned for TLPH5600, and why does it matter?

TLPH5600 luminous intensity is binned into standardized groups (K through U) ranging from 0.63–80 mcd, with TLPH5600 typically shipped in groups K–R. Each bag contains LEDs from only one intensity group-no mixing-to ensure visual consistency across assemblies. This binning matters because it eliminates visible brightness mismatch in multi-LED panels. For TLPH5600, specifying a target group (e.g., "M: 1.6–3.2 mcd") at order time guarantees uniformity, whereas un-binned orders may yield mixed groups.

What is the thermal resistance junction-to-ambient for TLPH5600, and how does it affect layout?

The TLPH5600 has a thermal resistance of 400 K/W junction-to-ambient, meaning each watt of dissipated power raises the junction temperature by 400 K above ambient. At its 30 mA / 2.5 V typical operating point (~75 mW), this yields ~30 °C rise-well within the 100 °C junction limit. To maintain this, avoid enclosing TLPH5600 in sealed plastic housings and ensure ≥25 mm² of 1 oz copper connected to at least one lead. This thermal behavior differentiates TLPH5600 from TLPR5600 (500 K/W), making TLPH5600 more tolerant of compact layouts.
