Vishay Semiconductor Opto Division TLHG5201

Overview

TLHG5201 from Vishay Semiconductors is a high-efficiency green LED in a 5 mm tinted non-diffused T-1¾ package, delivering 25–45 mcd luminous intensity at 10 mA with dominant wavelength 562–575 nm and ±14° viewing angle. It uses GaP-on-GaP technology, supports DC and pulsed operation up to 1 A surge current, and is rated for -40 °C to +100 °C ambient operation - ideal for status indication in industrial control panels.

For engineers reviewing the TLHG5201 datasheet, TLHG5201 pinout, TLHG5201 application, or TLHG5201 equivalent, this page provides verified optical, electrical, thermal, and mechanical specifications - including luminous intensity binning, wavelength categorization, forward voltage behavior at 20 mA, and tape orientation (AS12Z) - to support precise visual signaling design and BOM validation.

Technical Context

The TLHG5201 operates as a discrete visible-light emitter with fixed spectral output centered in the green band (562–575 nm dominant wavelength), optimized for high-brightness narrow-beam applications. Its ±14° half-intensity angle and non-diffused lens enable focused illumination without secondary optics.

It features GaP-on-GaP semiconductor construction, rated for 30 mA DC forward current and 100 mW power dissipation at ≤65 °C ambient, with thermal resistance of 350 K/W junction-to-ambient. Reverse voltage rating is 6 V, and junction capacitance is ≤50 pF at 0 V, 1 MHz.

FAQ

What is the luminous intensity range of TLHG5201 at 10 mA?

The TLHG5201 delivers a minimum luminous intensity of 25 mcd and a typical value of 45 mcd at 10 mA forward current, measured at 25 °C ambient temperature. This intensity range is binned to ensure IVmin/IVmax ≤ 0.5 within each packing unit, supporting uniform brightness in multi-LED assemblies. The TLHG5201 datasheet specifies no maximum intensity value beyond the typical.

What does the "AS12Z" suffix mean in TLHG5201-AS12Z?

The AS12Z suffix in TLHG5201-AS12Z indicates cathode-leading tape orientation: the cathode lead exits the carrier tape first during automated pick-and-place. This designation aligns with Vishay's tape coding standard (AS12 = cathode first), ensuring correct polarity alignment during SMT assembly. The "Z" denotes compliance with updated ammopack nomenclature per Vishay documentation.

What is the dominant wavelength specification for TLHG5201?

The TLHG5201 has a dominant wavelength range of 562 nm to 575 nm at 10 mA forward current, placing its output firmly in the green spectrum. This range is binned separately from red and yellow variants in the TLH.52.. series, enabling consistent color matching in multi-color indicator systems. Peak wavelength is specified at 565 nm typical.

Can TLHG5201 be driven directly from a 3.3 V microcontroller GPIO pin?

Yes, TLHG5201 can be driven directly from a 3.3 V microcontroller GPIO pin using an appropriate current-limiting resistor. With a forward voltage range of 2.0–3.0 V at 20 mA, a 100 Ω resistor yields ~23 mA drive current at 3.3 V - well within the 30 mA DC rating. Ensure GPIO sink/source capability meets the required current and verify thermal limits under continuous operation.

What is the maximum allowable ambient temperature for continuous operation of TLHG5201?

The TLHG5201 is rated for continuous operation across an ambient temperature range of -40 °C to +100 °C. At temperatures above +65 °C, the DC forward current must be derated linearly to maintain the 100 mW power dissipation limit and prevent junction temperature from exceeding 100 °C. Derating curves are provided in the TLHG5201 datasheet Figure 1.
