2N5786 PBFREE

Overview

The 2N5786 PBFREE is an NPN silicon power transistor manufactured by Central Semiconductor Corp. It is designed for general-purpose switching applications and features a TO-39 through-hole package. Key electrical specifications include a collector-emitter voltage (VCEO) of 40 V, a continuous collector current (IC) of 3.5 A, and a maximum power dissipation of 1 W. The device exhibits a DC current gain (hFE) ranging from 20 to 150 at a collector current of 1.6 A and a collector-emitter voltage of 2 V. Additional parameters include an emitter-base voltage (VEBO) of 3.5 V, a collector-emitter saturation voltage of 1 V, a transition frequency (fT) of 4 MHz, and a gain bandwidth product of 1 MHz.

Feature Summary

• Complementary silicon power transistor design intended for general-purpose switching applications
• Through-hole TO-39 package construction for robust mounting
• Lead-free plating configuration compliant with RoHS standards

Applications

• General purpose switching circuits
• Power amplifier stages
• Driver circuits for loads up to 3.5 A

Procurement Notes

Verify the specific ordering suffix requirements when requesting lead-free plated devices, as manufacturers may require adding 'PBFREE' to the base part number during the procurement process. Confirm current manufacturing status and availability directly with Central Semiconductor or authorized distributors, as production schedules and stock levels are subject to change. Ensure that the requested component matches the exact electrical ratings and package type specified in the official datasheet to avoid integration issues.

Selection Notes

Select the 2N5786 PBFREE for applications requiring an NPN power transistor with a 40 V rating and 3.5 A current capacity. Consider the complementary 2N5783 PNP variant if a matched pair is needed for push-pull configurations. Evaluate the thermal management requirements based on the 1 W power dissipation limit and the thermal resistance characteristics of the TO-39 package. Verify that the required gain bandwidth and switching speed meet the circuit's operational frequency demands.

Part Context

The 2N5786 PBFREE belongs to the 2N57 series of complementary silicon power transistors produced by Central Semiconductor Corp. This series includes the 2N5783 (PNP) and 2N5786 (NPN) types, which are designed as matched pairs for general-purpose switching and amplification tasks. The components are housed in durable TO-39 metal cans, providing reliable performance in various electronic systems where moderate power handling and voltage ratings are required.

Replacement Considerations

The 2N5783 PBFREE serves as the complementary PNP counterpart within the same series. For direct substitution, verify that alternative NPN transistors match the 40 V VCEO, 3.5 A IC, and 1 W Pd specifications. Ensure the replacement device utilizes a compatible TO-39 or equivalent through-hole package and meets the same electrical characteristics defined in the official datasheet.
