Overview
The SMMUN2213LT1 is a single NPN digital transistor from onsemi, housed in an SOT-23-3 surface-mount package. It integrates a built-in bias resistor network with a typical input resistance of 47 kOhms and a typical resistor ratio of 1. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. It operates within a temperature range of -55°C to +150°C and meets AEC-Q100 automotive qualification standards.
Feature Summary
- Integrates a single NPN transistor with a built-in bias resistor network for simplified circuit design.
- Optimized for high-speed switching applications through integrated internal resistance.
- Qualified for automotive electronics under the AEC-Q100 reliability standard.
Applications
- Automotive logic interface circuits
- General-purpose switching applications
- Driver circuits requiring compact form factors
Procurement Notes
Verify the specific suffix against official documentation, as the provided model lacks the final 'G' character found in common commercial variants like SMMUN2213LT1G. Confirm RoHS compliance status and exact packaging configuration directly with the manufacturer or authorized distributors before procurement.
Selection Notes
Select this component when a single NPN switch with a 47 kOhm base resistor is required. Ensure the 50 V collector-emitter voltage rating aligns with the target circuit's maximum operating voltage. Verify that the SOT-23-3 package dimensions fit the available PCB space constraints.
Part Context
This part belongs to the MMUN2213L series of bias resistor transistors. These devices are designed to replace multiple discrete components, reducing board space and assembly costs. The series includes various resistor ratios to accommodate different drive requirements while maintaining consistent electrical characteristics.
Replacement Considerations
SMMUN2213LT1G is a confirmed equivalent variant with identical electrical specifications. Verify if the 'G' suffix denotes RoHS compliance or specific tape-and-reel packaging requirements for your manufacturing process.
