Additional Details:

The MPSA94 TRE TIN/LEAD has a collector current rating of 500mA. It features a transition frequency (fT) of typically 50 MHz. The device is leaded and offers through-hole mounting. The “TRE” designation refers to the tape and reel packaging, facilitating automated assembly. The “TIN/LEAD” indicates the lead finish, which provides excellent solderability. It is important to note that leaded components require specific handling and disposal procedures to comply with environmental regulations. Designers should consider lead-free alternatives for new designs where applicable.
