Overview
The ON Semiconductor 2SD1936T-AC is an NPN bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. It is manufactured in a surface-mount SOT-89 package, providing a compact form factor suitable for space-constrained circuit designs. The device features a collector-emitter breakdown voltage of 40V and a continuous collector current rating of 1A. With a transition frequency of 150MHz, it supports operation in high-frequency circuits. The component is rated for a maximum power dissipation of 1W at 25°C ambient temperature and can operate within a junction temperature range from -55°C to +150°C.
Feature Summary
- NPN polarity configuration for standard switching and amplification tasks
- Surface-mount SOT-89 packaging for automated assembly and board space efficiency
- High transition frequency capability for RF and signal processing applications
Applications
- General-purpose signal amplification stages
- Low-power switching circuits
- Driver stages for small loads
Procurement Notes
Verify the specific ordering suffix 'AC' against the official ON Semiconductor datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the procurement channel provides traceability documentation compliant with RoHS directives. Cross-reference the manufacturer's part number directly to avoid confusion with similar packages or voltage ratings.
Selection Notes
Select this component when a 40V NPN BJT is required in a surface-mount SOT-89 footprint. Consider the 150MHz transition frequency for bandwidth requirements and verify that the 1A current rating meets the load demands. Evaluate thermal management needs given the 1W power dissipation limit in the specified package.
Part Context
This part belongs to the 2SD series of NPN transistors from ON Semiconductor. These devices are commonly used as replacements for older through-hole components in modern PCB layouts. The 2SD1936 variant specifically targets applications requiring moderate voltage handling and current capacity in a compact surface-mount format.
Replacement Considerations
Check for direct cross-reference part numbers such as the 2SD1936 without suffixes or equivalent parts from other manufacturers offering identical 40V/1A SOT-89 NPN specifications. Verify pin compatibility before substitution.
