What are the key features of LTR-3208?

High-sensitivity infrared phototransistor with 4 mA nominal light current enables reliable detection of weak IR signals in remote control and optical sensing applications
100 nA maximum dark current minimizes quiescent power draw, making LTR-3208 suitable for battery-powered sensing systems requiring low standby current
30 V minimum collector-emitter breakdown voltage allows operation in industrial circuits with elevated supply rails without risk of transistor breakdown

What is LTR-3208 used for?

The LTR-3208 is well-suited for consumer electronics IR remote control receivers, industrial object detection sensors, and optical proximity switches where high photosensitivity to near-infrared wavelengths is required. Its through-hole mounting simplifies prototyping and low-volume board assembly, and its high sensitivity reduces the IR emitter drive current needed to achieve reliable detection across typical indoor operating distances.

Frequently Asked Questions

What is the nominal light current of the LTR-3208 and how does its high sensitivity benefit IR remote control designs?

The LTR-3208 delivers a 4 mA nominal light current under standard infrared illumination conditions, reflecting its high-sensitivity classification. This elevated output current allows simpler demodulator circuits to decode IR signals reliably at distances exceeding 5 meters, reducing the required emitter LED drive current and improving overall system power efficiency in consumer remote control receivers and set-top box front panels.

What maximum dark current does the LTR-3208 specify and why does it matter for battery-powered sensor applications?

The LTR-3208 specifies a maximum dark current of 100 nA, which represents the leakage current flowing through the phototransistor when no infrared light is present. In battery-powered proximity sensors or IR barrier systems operating in sleep mode, this sub-microamp dark current is low enough to sustain weeks of standby operation on a standard 3 V coin cell without significant battery drain.

How should engineers account for the 22-week factory lead time when designing LTR-3208 into a new product?

With a 22-week factory lead time, engineers should place LTR-3208 purchase orders at least 6 months before the scheduled production start date to avoid supply chain delays. For designs entering NPI or prototyping phases, ordering buffer stock of at least 20% above projected build quantity is advisable. Procurement teams should also identify alternative high-sensitivity IR phototransistors with 30 V breakdown and comparable 4 mA light current as approved substitutes in case of extended supply constraints.
