MUN5213DW1T1G

Overview

The onsemi MUN5213DW1T1G is a dual NPN Bias Resistor Transistor (BRT) housed in a SOT-363 surface-mount package. It integrates two independent NPN transistors with monolithic bias resistor networks, each featuring a typical base resistor of 47 kΩ and a base-emitter resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. With a minimum DC current gain (hFE) of 80 and a power dissipation rating of 256 mW, it operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to replace discrete components
• Monolithic design reduces board space and simplifies circuit layout
• High thermal stability with an extended operating temperature range up to +150°C

Applications

• Low-power surface mount applications requiring compact transistor arrays
• General-purpose switching circuits utilizing pre-biased digital transistors
• Logic interface circuits where external biasing networks are eliminated

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm pinout compatibility and manufacturing lot details. Ensure that the selected variant matches the required tape and reel specifications for automated assembly processes. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a minimal footprint. The 47 kΩ input resistance suits standard logic levels, while the 50 V rating provides adequate headroom for low-voltage digital systems. Consider the SOT-363 package constraints regarding thermal dissipation limits during high-frequency switching operations.

Part Context

This part belongs to the MUN5213DW1 series of dual bias resistor transistors from onsemi. It is functionally related to other variants in the family, such as the MUN5213DW1T3G, which shares identical electrical characteristics but may differ in packaging format or shipping quantity. These devices are designed to streamline the design process by consolidating multiple discrete components into a single semiconductor solution.

Replacement Considerations

The MUN5213DW1T3G serves as a verified alternative within the same product family, offering identical electrical performance. Verify pin-to-pin compatibility and package dimensions before substitution to ensure seamless integration into existing PCB layouts without redesign.
