2SC3399-AC

Overview

The onsemi 2SC3399-AC is a silicon NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. It features a collector-emitter voltage rating of 160 V and a continuous collector current capacity of 700 mA. The device operates within a temperature range of -55°C to +150°C and is housed in a TO-92-3 through-hole package. Key electrical characteristics include a DC current gain (hFE) ranging from 40 to 400, a transition frequency (fT) of 120 MHz, and a power dissipation capability of 700 mW. These specifications define its suitability for low-power signal processing and control circuits.

Feature Summary

• High voltage tolerance suitable for medium-voltage switching environments
• Wide operating temperature range ensuring reliability under thermal stress
• Standardized through-hole packaging facilitating manual assembly and prototyping

Applications

• General-purpose signal amplification in audio and RF circuits
• Low-power switching loads in consumer electronics
• Driver stages for relay or LED control systems

Procurement Notes

Verify the specific suffix AC against the manufacturer's official datasheet to confirm pinout configuration and binning standards. Check for obsolescence status as component lifecycles change. Ensure the supplier provides traceable documentation matching the exact part number to avoid counterfeit risks. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when a robust NPN transistor with 160V breakdown voltage is required in a compact TO-92 package. Compare hFE bins if precise gain control is necessary for amplifier designs. Consider the 700mA limit for load calculations. Evaluate thermal management needs given the 700mW dissipation rating in enclosed spaces.
