Product Overview
Archer catalog number 276-144 (TIL413) is a high-speed silicon PIN photodiode designed for reverse-bias operation in optical pulse detection and infrared remote control applications. Encapsulated in a side-looker package with an integrated lens, this component provides high photosensitivity, low 15pF junction capacitance, and a fast 100ns response time for clean signal acquisition.
Key Features
- Silicon PIN construction optimized for reverse-bias operation
- Maximum reverse voltage rating: 30V
- Power dissipation limit: 150mW
- 100ns rise and fall switching response time
- Typical light current: 15 µA at 10V reverse bias
- Typical dark current: 5 nA at 10V reverse bias
- Side-looker package with molded lens and daylight-filtering dark epoxy
- Operating temperature range: -25°C to 100°C
Applications
- Restoring vintage infrared remote controls and dedicated receiver subassemblies
- Building breadboard pulse counters, optical tachometers, and robotic light barriers
- Assembling classic Radio Shack engineer notebook circuits requiring exact legacy semiconductor footprints
Frequently Asked Questions
Which lead corresponds to the cathode on the TIL413?
The package pinout is printed directly on the card: viewing the component from the front with the lens facing you and leads pointing down, the cathode is the left lead.
Does this diode respond to visible light?
The black molded epoxy body acts as a daylight filter, attenuating visible ambient light to prioritize infrared wavelengths.
Why buy this specific vintage unit instead of a modern multi-pack?
This verified TIL413 provides the exact optical geometry, lead pitch, and electrical response called out in period Radio Shack project guides and vintage electronics schematics. Sourcing this genuine period component eliminates guesswork and fitment issues on vintage restoration work. Shipping is $8 flat rate, free once the order passes $28, and orders leave the Idaho warehouse the same or next business day.
Nothing quite matches the quiet satisfaction of installing a correct period-authentic component and seeing an old circuit respond on the first pass. Wire it into your circuit and let it read the beam.
