Single Bipolar Transistors datasheet and documents for 2SA1381CSTU
Single Bipolar Transistors Overview
The 2SA1381CSTU is a PNP epitaxial silicon transistor manufactured by onsemi. It features a collector-emitter voltage (VCEO) of -300 V and a maximum collector current (IC) of 1.5 A. The device operates with a transition frequency (fT) of 150 MHz and exhibits low reverse transfer capacitance (Cre) of 2.3 pF at VCB = -30 V. It utilizes the TO-220AB package for thermal management.
Single Bipolar Transistors Feature Summary
- High voltage capability rated at -300 V collector-emitter breakdown
- Low reverse transfer capacitance for high-frequency signal integrity
- Excellent gain linearity designed to minimize total harmonic distortion
Single Bipolar Transistors Applications
- Audio amplification circuits
- Voltage amplifier stages
- Current source implementations
- CRT display and video output drivers
Single Bipolar Transistors Procurement Notes
Verify the specific suffix 'CSTU' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required -300 V rating and 150 MHz frequency performance for your circuit design before procurement.
Single Bipolar Transistors Selection Notes
Select this component for applications requiring high-voltage PNP switching or amplification with low distortion. Consider its 150 MHz transition frequency for high-speed audio or video signal processing where gain linearity is critical to maintaining signal fidelity.
Single Bipolar Transistors Part Context
This part belongs to the 2SA1381 series of PNP epitaxial silicon transistors originally developed by Fairchild Semiconductor, now integrated into onsemi's portfolio. It serves as a complement to the NPN 2SC3503/KSC3503 devices in push-pull amplifier configurations.
Single Bipolar Transistors Replacement Considerations
Official substitutes include the 2SC3503 or KSC3503 NPN counterparts for complementary pairs. Verify pinout compatibility and electrical parameters such as VCEO and IC ratings when replacing with other manufacturers' equivalents.
