2N6426RLRA

Overview

The onsemi 2N6426RLRA is an NPN silicon Darlington transistor in a TO-92 package. It features a collector-emitter voltage of 40 Vdc and continuous collector current of 500 mAdc. DC current gain ranges from 14,000 to 300,000 depending on operating conditions. The device operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Darlington configuration provides high DC current gain for sensitive signal amplification
• Suitable for low-power switching applications with moderate voltage ratings
• Through-hole mounting via standard TO-92 leaded package

Applications

• Low-noise preamplifier stages
• General-purpose switching circuits
• Sensor interface circuits

Procurement Notes

Verify the specific RLRA suffix indicates tape and reel packaging containing 2,000 units per reel. Confirm RoHS compliance status as the datasheet notes availability of Pb-Free packages but does not explicitly confirm this specific suffix is compliant. Ensure the obsolete status noted by distributors is acceptable for the design lifecycle.

Selection Notes

Select this component when high current gain is required in a small through-hole package. Verify that the 40 V collector-emitter breakdown voltage meets circuit requirements. Consider thermal dissipation limits at higher ambient temperatures or case-mounted operations.

Part Context

This part belongs to the 2N6426/2N6427 family of NPN Darlington transistors manufactured by onsemi. The RLRA suffix specifically denotes the Tape & Reel packaging format, distinguishing it from bulk box variants like the standard 2N6426.

Replacement Considerations

The 2N6427 is a variant within the same datasheet offering slightly different gain characteristics. Verify pinout compatibility and electrical parameters before substituting.
