MUN2213JT1

Overview

The onsemi MUN2213JT1 is a single NPN pre-biased bipolar transistor designed for surface-mount applications. It integrates an internal base resistor network to simplify circuit design and reduce component count. The device features a collector-emitter voltage (Vceo) of 50 V and a continuous collector current rating of 100 mA. It is housed in the SC-59 package, which provides a compact footprint suitable for space-constrained designs. The unit operates within a temperature range of -55°C to +150°C and has a power dissipation capability of 338 mW. This component belongs to the digital transistor family, offering reliable switching performance for logic interface tasks.

Feature Summary

• Integrates internal biasing resistors to minimize external component requirements
• Provides high-density packaging for efficient board space utilization
• Supports wide operating temperature ranges for robust environmental stability

Applications

• Logic level shifting between different voltage domains
• Switching applications in consumer electronics
• Interface circuits for microcontroller input/output protection

Procurement Notes

Verify the specific ordering suffix JT1 to ensure correct tape-and-reel packaging configuration compatible with automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications and pinout definitions for accurate PCB layout implementation.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-power switching tasks. The 50 V breakdown voltage suits general-purpose logic interfacing where higher voltage ratings are unnecessary. Consider the SC-59 package dimensions against available board real estate. Ensure the 100 mA current limit meets the load requirements without exceeding thermal dissipation constraints in the target enclosure.
