概述

Description

2SD2114KT146W is a 2SD-series NPN silicon power transistor. Devices in this family are used for high-voltage, high-current switching and linear amplification in power supplies, audio amps, and motor drives. The exact electrical ratings (Vceo, Ic, Pd, hFE, package) vary by lot and variant, so the KT146W suffix primarily indicates a packaging/lot code for a specific manufacturer. Typical applications require proper heatsinking and a suitable base drive; observe safe operating area and parasitic inductance in switching use.
For accurate introduction, consult the specific datasheet from the vendor or distributor (to confirm Vce, Ic, Ptot, hFE, pinout, and package type). If you provide the manufacturer or a link, I can summarize the exact specs.

Package

Do you mean the semiconductor package type (e.g., TO-92, SOT-23) or the shipping/packing format (e.g., reel, tube)?

Pinout

- Pin count: 3 pins (three-terminal transistor: base, collector, emitter).
- Function: NPN transistor (power/high-voltage switching/ amplification). Pinout depends on the specific package, so check the datasheet for your layout.

Manufacturer

Manufacturer: Toshiba (Toshiba Electronic Devices & Storage Corporation).
What kind of company: A Japanese multinational electronics and semiconductor company that designs and manufactures semiconductors, transistors, storage devices, and other electronic components.

Application

2SD2114KT146W is a high‑voltage NPN power transistor. Typical applications include:
- Switching power supplies (DC‑DC converters, SMPS)
- Linear regulators (pass/transistor for regulation)
- Audio power amplifier output stages
- Motor control and driver circuits
- General switching/driving tasks in consumer and industrial electronics
Note: confirm exact voltage/current ratings from the datasheet for your design.
