BC817-25LT1 Description

Short technical summary and product information.

The BC817-25LT1 is an NPN silicon bipolar junction transistor from On Semiconductor, designed for general-purpose switching and amplifier applications. Key electrical ratings include a maximum collector-emitter voltage of 45V, collector-base voltage of 50V, and emitter-base voltage of 5V. The continuous collector current is rated at 500mA, with a power dissipation of 225mW on FR-5 board (300mW on alumina substrate).

 

DC current gain (hFE) ranges from 160 to 400 at 100mA/1V, with a minimum of 40 at 500mA/1V. The transistor offers a transition frequency of at least 100MHz and a typical output capacitance of 10pF. Maximum collector cutoff current is 100nA at 20V VCB, increasing to 5µA at 150°C. The device is housed in a surface-mount SOT-23 package (TO-236-3, SC-59) and is Pb-Free, Halogen Free, and RoHS compliant.

 

This part is part of the BC817-25L series, which includes variants with different gain ranges. Cross-references include BC817-16L and BC817-40L series. Suitable for low-power circuits requiring moderate voltage and current handling.
