Single Bipolar Transistors

STT13005D Description

The STT13005D from STMicroelectronics is a high-voltage NPN bipolar junction transistor (BJT) designed for demanding power-switching applications. Housed in a SOT32-3 (TO-126) through-hole package, it offers a robust 400V collector-emitter breakdown voltage (V_CE) and a 2A continuous collector current (I_C). With a 45W maximum power dissipation, this transistor is engineered for efficiency in high-power circuits. Its low collector cutoff current (250µA max) and DC current gain (h_FE ≥ 10 @ 500mA, 5V) ensure reliable performance in switching and amplification roles.

STT13005D Features

• High Voltage Rating: 400V V_CE makes it suitable for offline power supplies and industrial applications.
• High Current Handling: 2A I_C and 1.5V V_CE(sat) @ 400mA/1.6A ensure minimal power loss in switching.
• Thermal Resilience: Operates up to 150°C junction temperature (T_J), ideal for high-temperature environments.
• Compliance: ROHS3 and REACH compliant, meeting environmental standards.
• Low Leakage: 250µA max cutoff current enhances energy efficiency.

STT13005D Applications

• Switching Power Supplies: Efficiently manages high-voltage switching in AC-DC converters.
• Motor Control: Drives inductive loads in industrial motor drivers and inverters.
• Electronic Ballasts: Used in fluorescent and LED lighting systems.
• CRT Deflection Circuits: High-voltage handling suits CRT monitor applications.
• Obsolete but Reliable: While marked obsolete, it remains a trusted choice for legacy designs requiring proven performance.

Conclusion of STT13005D

The STT13005D excels in high-voltage, medium-power applications, offering a balance of ruggedness, efficiency, and thermal stability. Its TO-126 package ensures easy integration into through-hole designs, while its high gain and low saturation voltage minimize losses. Though obsolete, it remains a viable option for engineers maintaining or upgrading legacy systems requiring 400V switching capability. For modern designs, consider newer alternatives, but the STT13005D’s reliability in demanding conditions ensures its enduring relevance.
