NPN Power Transistor EB689083428 100 V 25 A

NPN power transistor EB689083428 is a discrete high-current semiconductor device specified for a maximum collector–emitter voltage of 100 V and a collector current up to 25 A. Intended for switching and linear amplification in power electronics, motor drivers, and power supply circuits, the transistor is optimized for applications that require robust current handling and predictable thermal behaviour when mounted on an appropriate heatsink.

Advantages

The transistor offers high current capacity and a 100 V voltage rating that suit mid-voltage power stages. Its design supports both switching and amplification tasks, providing low saturation characteristics under specified operating conditions and reliable performance when thermal management measures are applied. The device's electrical ratings make it compatible with common power-supply topologies and motor-drive circuits.

Suitable for

• Switching stages in DC power supplies and converters
• Motor driver output stages for DC motors and actuators
• Linear amplification in power control circuits
• Load switching and relay replacement in industrial control

Key specifications

• Transistor type: NPN bipolar power transistor
• Maximum collector–emitter voltage (Vce): 100 V
• Maximum collector current (Ic): 25 A
• Suitable for operation in switching and linear modes
• Requires external heatsinking for high-power dissipation

How to use

Integrate the NPN power transistor into the circuit according to standard bipolar transistor layout practices, observing correct pin connections for base, collector and emitter. Ensure gate/base drive and biasing networks provide appropriate base current and limit base–emitter voltage within safe limits. For high-current operation, mount the transistor on a suitably rated heatsink and provide adequate PCB copper for thermal conduction and current paths. Include proper snubbers, flyback diodes or RC suppression where inductive loads are present to protect the device from voltage transients.

Usage recommendations

Operate the transistor within specified voltage and current ratings and use a properly sized heatsink. Verify thermal resistance in your assembly and add overcurrent protection or fusing for reliability. For switching applications, ensure base drive circuitry is dimensioned to achieve the required turn-on and turn-off times while preventing excessive base dissipation.
