Overview
The Nexperia PUMD48 is a dual Resistor-Equipped Transistor (RET) containing one NPN and one PNP transistor in a SOT363-3 (TSSOP6) package. It features built-in bias resistors with R1 values of 47 kΩ for the NPN and 2.2 kΩ for the PNP, both paired with R2 at 47 kΩ. The device supports a collector-emitter voltage (VCEO) of 50 V and an output current (IO) of 100 mA per transistor. Total power dissipation is rated at 300 mW at 25 °C ambient temperature. Key electrical characteristics include a DC current gain (hFE) of 80 for the NPN at 5 mA and 100 for the PNP at 10 mA.
Feature Summary
- Integrates NPN and PNP transistors with pre-biased resistors to simplify circuit design.
- Reduces component count and pick-and-place costs compared to discrete solutions.
- Provides high output current capability suitable for low-current peripheral drivers.
Applications
- Low current peripheral driver
- Control of IC inputs
- Replaces general-purpose transistors in digital applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as tape and reel quantities or cut tape options. Ensure the requested part number matches the exact resistor values and package type specified in the design requirements before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a compact SOT363-3 package. Verify that the required base drive currents align with the internal 47 kΩ and 2.2 kΩ bias resistors. Confirm thermal management capabilities meet the 300 mW total power dissipation limit under expected operating conditions.
Part Context
The PUMD48 belongs to Nexperia's family of NPN/PNP Resistor-Equipped Double Transistors. It serves as a complement to other RET devices like the PUMH series (NPN/NPN) and PUMB series (PNP/PNP). This specific model integrates distinct bias networks for complementary switching operations within a single ultra-small surface-mounted device.
Replacement Considerations
Direct functional substitutes include the PUMD48,115 and PUMD48,165 variants from Nexperia, which share identical electrical specifications but may differ in packaging formats or manufacturing site codes. Verify pin compatibility and resistor tolerances when cross-referencing with other manufacturers' dual RETs.
FAQ
What are the specific resistance values for the built-in bias resistors?
The NPN transistor (TR1) has a bias resistor R1 of 47 kΩ and R2 of 47 kΩ. The PNP transistor (TR2) has a bias resistor R1 of 2.2 kΩ and R2 of 47 kΩ.
What is the maximum total power dissipation for the device?
The total power dissipation (Ptot) is 300 mW when the ambient temperature is 25 °C or lower.
Does the PUMD48 have automotive qualification?
No, unless explicitly stated otherwise in specific product data sheets, this product is not qualified for automotive use according to AEC-Q101 standards.
