Overview
The NSVMMUN2233LT3G is an NPN Digital Transistor (BRT) from onsemi, featuring a monolithic bias network with R1 = 4.7 kΩ and R2 = 47 kΩ. It integrates a single transistor with series base and base-emitter resistors to replace discrete components. The device operates with a maximum collector-emitter voltage of 50 Vdc and continuous collector current of 100 mAdc at 25°C. Packaged in SOT-23 (CASE 318), it supports junction temperatures from -55°C to +150°C. This component simplifies circuit design by reducing board space and component count while maintaining RoHS compliance.
Feature Summary
- Integrates NPN transistor with monolithic bias resistor network
- Reduces system cost and board space by eliminating external resistors
- AEC-Q101 qualified and PPAP capable for automotive applications
- Pb-Free, Halogen Free/BFR Free, and RoHS compliant
Applications
- Automotive electronics requiring unique site and control change requirements
- General-purpose switching circuits
- Driver circuits for logic interfaces
Procurement Notes
Verify the specific ordering suffix LT3G corresponds to the SOT-23 package with 10,000 units per tape and reel configuration. Confirm that the NSV prefix indicates AEC-Q101 qualification and PPAP capability if automotive standards are required. Ensure the datasheet revision matches the intended manufacturing specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN switch with integrated biasing is needed. The 4.7 kΩ series resistor and 47 kΩ base-emitter resistor provide standard biasing for general logic levels. Consider the SOT-23 package dimensions and thermal dissipation characteristics relative to the application's ambient temperature and power constraints.
Part Context
This part belongs to the MUN2233 family of digital transistors, which includes variants like MMUN2233L and MUN5233. These devices share similar electrical characteristics but differ in packaging and specific resistor values or configurations. The NSV prefix denotes automotive-grade qualification within this product line.
Replacement Considerations
Direct substitutes include MMUN2233LT1G and other MUN2233 variants within the same family. Verify pin compatibility and electrical parameters such as breakdown voltage and current gain before substitution.
