## Description

The NTE2540 is a Silicon NPN transistor from NTE Electronics, specifically designed as a Darlington, High Voltage Switch. It is housed in a TO-220 Full Pack package, suitable for through-hole mounting.

Key electrical characteristics include a high DC current gain (hFE) of 600 minimum at VCE = 2V and IC = 2A, and 100 minimum at VCE = 2V and IC = 4A. The device can withstand a Collector Base Voltage (VCBO) of up to 600V and a Collector Emitter Voltage (VCEO) of up to 400V. The maximum Collector Current (IC) is 6A, with a maximum Base Current (IB) of 1A.

Absolute maximum ratings specify a Collector Power Dissipation (PC) of 2W at TA = +25°C and 25W at TC = +25°C. The operating junction temperature (TJ) can reach up to +150°C, with a storage temperature range of -55°C to +150°C.

Electrical characteristics also detail parameters such as Collector Cutoff Current (ICBO) of 0.5mA max, Emitter Cutoff Current (IEBO) of 3mA max, and Collector-Emitter Breakdown Voltage (V(BR)CEO) of 400V min. Saturation voltages (VCE(sat) and VBE(sat)) are specified at 2.0V and 2.5V maximum respectively under specific test conditions. Capacitance (Cob) is 35pF typical at 1MHz, and switching times (Turn-On, Storage, Fall) are in the microsecond range.
