Frequently Asked Questions
What are the key electrical ratings of the BCR 162 PNP digital transistor?
The BCR 162 is rated for a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 50 V. It integrates a 4.7 kΩ base resistor internally, allowing direct connection to logic-level outputs without additional external bias resistors, simplifying design in LED switching and low-power load control applications.
In which circuit applications does BCR 162 replace a discrete transistor-plus-resistor combination?
BCR 162 replaces a discrete PNP transistor and external base resistor in LED driver circuits, relay switches, and logic-level load switches handling up to 100 mA. IoT sensor nodes, portable consumer electronics, and industrial control boards benefit from its integrated 4.7 kΩ base resistor for direct 3.3 V or 5 V microcontroller GPIO interfacing.
How does the SOT-23 package of BCR 162 benefit high-density PCB layouts compared to through-hole alternatives?
The BCR 162 SOT-23 3-pin package occupies a footprint roughly 1.3 mm × 2.9 mm, far smaller than TO-92 or SOT-89 through-hole counterparts. Combined with its integrated 4.7 kΩ base resistor that removes one external component, it allows designers to fit more switching circuits per unit PCB area in wearables, handheld devices, and dense IoT modules.
