Overview
The Panasonic 2SA1748G is a silicon PNP epitaxial planar transistor designed for high-frequency amplification. It operates with a collector-emitter voltage of -50 V and a maximum collector current of -50 mA, dissipating up to 150 mW. The device features a minimum transition frequency (fT) of 250 MHz at an emitter current of 2 mA and a low collector output capacitance (Cob) of 1.5 pF. DC current gain (hFE) ranges from 200 to 500 depending on the rank. It utilizes the SMini3-F2 surface-mount package.
Feature Summary
- High transition frequency suitable for RF applications
- Low collector output capacitance for signal integrity
- Compact S-Mini package enabling automated insertion
Applications
- High-frequency amplification circuits
- General electronic equipment
- Communications equipment
Procurement Notes
Verify the specific ordering suffix 'GRL' against official documentation, as datasheets may only list the base part number. Confirm RoHS compliance status and check the manufacturer's lifecycle page for maintenance or discontinuation notices before finalizing procurement plans.
Selection Notes
Select this component when a small-signal PNP transistor with high-speed switching capabilities is required. Ensure the design accommodates the -50 V voltage rating and verify that the SMini3-F2 footprint matches the PCB layout constraints.
Part Context
This component belongs to the Panasonic discrete semiconductor transistor family. It serves as the complementary pair to the NPN 2SC4562G transistor within the manufacturer's lineup for matched circuit designs.
Replacement Considerations
The 2SC4562G is the documented complementary NPN transistor. Verify pinout compatibility and electrical parameters before substituting with other general-purpose PNP transistors in existing designs.
FAQ
What is the transition frequency of the 2SA1748G?
