2SA1770S-AN

Single Bipolar Transistors Overview

The onsemi 2SA1770S-AN is a PNP single bipolar junction transistor (BJT) utilizing MBIT process technology. It features a collector-to-emitter voltage of 160 V and a continuous collector current rating of 1.5 A, with a peak pulse current capability of 2.5 A. The device operates within a junction temperature range of -55°C to +150°C and dissipates up to 1 W of power. Key electrical characteristics include a DC current gain (hFE) ranging from 80 to 400 depending on the rank, a transition frequency (fT) of 120 MHz, and a low collector-to-emitter saturation voltage of 200 mV at 500 mA. It is housed in an NMP (SC-71) surface-mount package.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'S' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer's documentation aligns with the required hFE ranking for your circuit design, as gain varies between S and T ranks. Ensure the SC-71 footprint matches your PCB layout constraints before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring robust PNP switching with moderate current handling up to 1.5 A. Consider the 160 V breakdown voltage for higher voltage rail management compared to standard 50 V transistors. Evaluate the thermal dissipation requirements against the 1 W limit and ensure adequate heat sinking or copper area allocation for the NMP package.

Single Bipolar Transistors Part Context

This part belongs to the 2SA1770 series manufactured by onsemi. It is functionally paired with the 2SC4614 NPN transistor in complementary configurations. Both devices share similar electrical profiles and are designed for use in general-purpose switching and amplification tasks within consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

The 2SA1770T-AN serves as a direct alternative with identical electrical specifications but differs in shipping configuration. Verify pinout compatibility if substituting with other SC-71 PNP transistors, as lead assignments may vary across different manufacturers.
