TTA1713-Y,LF is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Toshiba Semiconductor and Storage. Its product description is TRANS PNP 45V 0.5A S-MINI. Review the specifications below when checking this part for your BOM.
The TTA1713 is a silicon PNP epitaxial type bipolar transistor manufactured by Toshiba Semiconductor and Storage. It operates with collector-base, collector-emitter, and emitter-base voltages of -50 V, -45 V, and -5 V respectively. The device supports a maximum collector current of -500 mA and base current of -50 mA. DC current gain (hFE) ranges from 120 to 390 depending on the rank. Transition frequency is typically 80 MHz at -10 mA collector current. The component is housed in an S-Mini package.
Verify the specific hFE rank suffix (Y or GR) required for your design, as this determines the minimum gain threshold. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement. Ensure the ordering code matches the exact electrical characteristics needed for the target application.
Select the Y rank for applications requiring a minimum hFE of 120, or the GR rank for a minimum hFE of 180. Consider the -45 V collector-emitter voltage limit when designing circuits with higher supply rails. Verify thermal dissipation requirements against the 200 mW power rating under specified board conditions.
This component belongs to Toshiba's lineup of small-signal and power bipolar junction transistors designed for general-purpose amplification and switching. The S-Mini package offers a compact footprint suitable for modern consumer electronics and industrial control boards where space constraints are critical.
