MUN5330DW1T1G

Overview

The MUN5330DW1T1G is a dual digital transistor array manufactured by onsemi, integrating one NPN and one PNP bipolar junction transistor with built-in bias resistors. It is housed in a surface-mount SOT-363 (SC-88/SC70-6) package. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA per element. Maximum power dissipation is rated at 250mW. The integrated base resistor (R1) and emitter resistor (R2) are both specified as 1 kΩ. DC current gain (hFE) is guaranteed to be at least 3 at 5mA collector current and 10V. Collector cutoff current is limited to 500nA, with a maximum saturation voltage of 250mV.

Feature Summary

• Integrates complementary NPN and PNP transistors with pre-biased resistors for simplified circuit design
• Utilizes compact SOT-363 surface-mount packaging for space-constrained applications
• Provides low saturation voltage characteristics for efficient switching performance

Applications

• General-purpose switching circuits requiring complementary logic levels
• Driver stages for small-signal loads in consumer electronics
• Logic level translation interfaces between different voltage domains

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the package type matches the required SOT-363 footprint. Ensure the revision suffix aligns with the intended manufacturing date code. Cross-reference the part number with authorized distributor catalogs to avoid counterfeit sources. Validate RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single package solution for both NPN and PNP switching is required. The 1kΩ internal bias resistors suit applications driving moderate base currents without external components. Consider the 50V rating for low-voltage digital logic systems. Evaluate the 250mW power dissipation limit against thermal constraints in dense PCB layouts. Compare hFE minimums with specific load requirements to ensure adequate gain margins.

Part Context

This part belongs to the MUN5330 series of dual digital transistors from onsemi. It shares the SOT-363 form factor with other variants like MUN5314 and MUN5316, which differ primarily in internal resistor values. The series is designed to replace discrete resistor-transistor networks, reducing board space and assembly costs. It complements single-element digital transistors like the MUN5230 for more complex logic functions.

Replacement Considerations

Direct pin-compatible substitutes include other onsemi MUN53xx series devices in SOT-363 packages, such as MUN5314DW1T1G or MUN5316DW1T1G, provided their internal resistor ratios match the circuit design requirements. Verify that alternative parts maintain the same 50V voltage rating and 100mA current capacity.
