Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix ZL1 corresponds to the Ammo Box shipping configuration as documented in the official datasheet. Confirm that the component carries the G suffix if lead-free compliance is required for the assembly process. Ensure the marking code matches the 7-25 designation for accurate identification upon receipt.

Single Bipolar Transistors Selection Notes

Select this component when a minimum hFE of 160 is required at higher collector currents compared to standard variants. The TO-92 package limits power dissipation to 625 mW without active cooling. Verify that the 45 V collector-emitter breakdown voltage meets the circuit's maximum operating requirements.

Single Bipolar Transistors Part Context

This part belongs to the BC337 family of NPN silicon amplifier transistors manufactured by onsemi. The family includes variants differentiated by DC current gain ranges (-16, -25, -40) and packaging types. The BC337-25 specifically targets applications requiring moderate to high current gain characteristics within a standard through-hole footprint.
