2SB1205T-TL-E Description

Short technical summary and product information.

The 2SB1205T-TL-E is a PNP bipolar junction transistor from On Semiconductor, designed for medium-power switching and amplification applications. It features a maximum collector-to-emitter voltage of -20V and a continuous collector current of -5A, with a pulse current capability of -8A. The transistor offers a typical gain-bandwidth product of 320MHz and a minimum DC current gain of 200 at 500mA, 2V (Rank T variant).

 

This transistor is housed in a surface-mount TP-FA package (TO-252-3, SC-63) with gull wing leads and a tab for heat dissipation. It has a maximum power dissipation of 10W at case temperature 25°C and 1W at ambient temperature. The junction temperature rating is 150°C, and the storage temperature range is -55°C to +150°C.

 

The device utilizes FBET and MBIT processes for low saturation voltage and fast switching speeds. Typical switching times include a turn-on time of 40ns, storage time of 200ns, and fall time of 10ns. The low VCE(sat) of -500mV at 3A makes it suitable for voltage regulators, relay drivers, and lamp drivers.

 

The 2SB1205T-TL-E is supplied in tape and reel packaging with a minimum quantity of 700 pieces per reel. It is RoHS3 compliant (unverified) and REACH unaffected. The MSL rating is 1 (unlimited, unverified).
