The Toshiba 2SD2695 is a Silicon NPN Epitaxial Darlington Power Transistor designed for micro motor drive, hammer drive, and power amplifier applications. It features a high DC current gain of 2000 (min) at VCE = 2 V and IC = 1 A, alongside a low saturation voltage of 1.5 V (max) under identical conditions. The device includes an integrated Zener diode between the collector and base terminals. Absolute maximum ratings specify a collector-emitter voltage of 60 V, a collector current of 2 A, and a collector power dissipation of 0.9 W at 25°C ambient temperature.
Verify RoHS compatibility status by contacting the manufacturer or authorized distributor, as environmental compliance varies by production lot. Confirm that the specific ordering suffix matches the required lead-free or standard configuration. Review the latest Toshiba Semiconductor Reliability Handbook for derating concepts and methods before finalizing component selection for your design.
Select this component when high current amplification is required in a compact package. Ensure the operating collector current remains within the 2 A limit and verify thermal management capabilities for the 0.9 W power dissipation rating. Consider the built-in Zener diode for base-collector transient suppression needs. Evaluate the transition frequency characteristics against the target application speed requirements.
This part belongs to the family of Silicon NPN Epitaxial Type transistors manufactured using the PCT process. It is housed in a JEDEC TO-92MOD package, also designated as TOSHIBA 2-5J1A. The device weighs approximately 0.36 g. It is distinct from standard bipolar transistors due to its Darlington configuration, which provides significantly higher current gain than single-transistor designs.
No public confirmed substitute part numbers are available in the provided documentation.
