Overview
The onsemi 2SA1502-TB-E is a PNP bipolar junction transistor designed for surface-mount applications. It features a maximum collector-emitter voltage of -50 V and a continuous collector current of -1 A. The device operates with a transition frequency of 180 MHz and supports a maximum power dissipation of 1 W. It utilizes the CPA (TO-243AA) package, which provides a compact form factor suitable for high-density circuit designs. The component is rated for junction temperatures up to 150°C and complies with RoHS3 standards.
Feature Summary
- High current handling capability for single-ended amplifier stages
- Compact surface-mount packaging for space-constrained layouts
- Optimized transition frequency for RF signal processing
Applications
- Audio amplifier output stages
- General-purpose switching circuits
- RF driver stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and compliance status. Confirm that the supplier source provides authentic components with traceable documentation. Check for any regional export control classifications or material declarations required for your specific manufacturing environment before finalizing procurement orders.
Selection Notes
Select this component when a PNP transistor with 1 A current capacity and 50 V breakdown voltage is required in a surface-mount format. Ensure the thermal management design accommodates the 1 W power dissipation limit within the CPA package constraints. Verify that the operating frequency requirements align with the 180 MHz transition frequency specification for optimal performance.
Part Context
This part belongs to the 2SA series of PNP transistors from onsemi, engineered for general-purpose and audio applications. The CPA package variant offers improved thermal performance compared to smaller SOT packages while maintaining a low profile. It serves as a complementary device to NPN counterparts in push-pull configurations.
Replacement Considerations
Direct substitutes include the 2SA1502 without suffix variations if pinout compatibility is confirmed. Alternative packages such as TO-243AA equivalents may require schematic review. Verify gain group and saturation voltage specifications match the original design requirements before substitution.
