Overview
The STA404A is an NPN Darlington general-purpose transistor manufactured by Sanken Electric USA Inc. It features a collector-base voltage (VCBO) and collector-emitter voltage (VCEO) of 200 V, with an emitter-base voltage (VEBO) rating of 6 V. The device supports a continuous collector current (IC) of 3 A at 25°C ambient temperature, rising to 20 A at 25°C case temperature, and a peak collector current (ICP) of 6 A under pulsed conditions. Key electrical characteristics include a minimum DC current gain (hFE) of 1000 at IC=1A and VCE=4V, and a maximum saturation voltage (VCE(sat)) of 2.0 V at IC=1A and IB=1.5mA. The maximum power dissipation (PT) is 6 W at 25°C ambient, with a junction temperature (Tj) limit of 150°C.
Feature Summary
- High DC current gain capability suitable for general-purpose amplification and switching applications.
- Robust pulse current handling capacity for transient load requirements.
- Integrated equivalent circuit design simplifies driver interface connections.
Applications
- General-purpose switching circuits
- Amplifier stages requiring high current gain
- Driver interfaces for inductive loads
Procurement Notes
Verify the specific package variant against the official datasheet before ordering. Confirm thermal management requirements align with the specified power dissipation limits. Ensure supply chain sources provide authentic components from Sanken Electric or authorized distributors to guarantee parameter compliance.
Selection Notes
Select this component when a 200 V blocking voltage and 3 A continuous current are required. Consider the high hFE specification for low drive current applications. Evaluate thermal resistance parameters if operating near maximum power dissipation limits without adequate heatsinking.
Part Context
The STA404A belongs to Sanken Electric's STA series of NPN Darlington transistors. This family provides general-purpose solutions characterized by high current gain and robust voltage ratings. The device utilizes a standard 10-pin STA package configuration for mounting and thermal performance.
Replacement Considerations
Consult the manufacturer's datasheet for direct pin-compatible substitutes within the same product family. Verify that alternative components meet or exceed the 200 V voltage ratings and 3 A current specifications.
