The 12A02SS-TL-E is a single NPN bipolar junction transistor manufactured by onsemi. It features a collector-emitter breakdown voltage of 30 V and a maximum continuous collector current of 700 mA. The device operates with a transition frequency of 540 MHz and supports a maximum power dissipation of 600 mW. DC current gain is specified at a minimum of 300 when tested at 50 mA and 2 V. The saturation voltage is limited to 190 mV at 10 mA base current and 200 mA collector current. The component utilizes a 3-MCPH surface-mount package, equivalent to SC-70 or SOT-323, and is rated for junction temperatures up to 150°C.
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and material declarations directly from the datasheet before finalizing procurement orders to meet regulatory requirements.
Select this component for designs requiring a small-form-factor NPN transistor with moderate current handling and high-speed performance. Ensure the circuit design accounts for the 600 mW power dissipation limit and verify that the required current gain meets the minimum specification under actual operating conditions.
This part belongs to the 30C02 series of small-signal NPN transistors. It shares core electrical characteristics with variants such as the 30C02MH-TL-E, differing primarily in packaging or manufacturing lot details. The series is designed for general-purpose amplification and switching tasks in portable and compact electronic devices.
The 30C02MH-TL-E is a confirmed substitute within the same product family. Verify pinout compatibility and package dimensions before implementation.
