Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation, as the provided documentation identifies Toshiba as the original designer while EVVO is listed as the distributor or secondary source. Confirm that the component meets the specific RoHS compliance status indicated in the source data, which notes non-compliance in one record. Ensure the package type matches the required 3-pin leaded form factor for your assembly process.

Single Bipolar Transistors Selection Notes

Select this component when a low-power PNP transistor with moderate voltage handling is required for amplifier stages. The 230 V breakdown voltage provides sufficient headroom for many audio and RF driver applications. Consider the 2W power dissipation limit and ensure adequate heatsinking or thermal management is implemented to maintain junction temperatures within the specified 150°C maximum operating range.

Single Bipolar Transistors Part Context

The 2SA1837 is a legacy PNP power transistor originally developed by Toshiba. It is commonly used in complementary pairs with NPN devices like the 2SC4793. The component belongs to the family of general-purpose bipolar junction transistors suitable for linear amplification tasks where moderate current and high voltage are needed.
