Overview
The PEMB24 is a PNP/PNP resistor-equipped transistor manufactured by Nexperia, formerly NXP Semiconductors. It integrates two PNP transistors with built-in bias resistors (R1 = 100 kΩ) in a SOT666 plastic surface-mounted package. The device features a collector-emitter voltage of -50 V and a DC output current of -20 mA per transistor. Key electrical characteristics include a DC current gain (hFE) of 80 at IC = -5 mA and a collector-emitter saturation voltage of -150 mV at IC = -5 mA. The component supports reflow soldering and operates within an ambient temperature range of -65 °C to +150 °C.
Feature Summary
- Built-in bias resistors simplify circuit design and reduce component count
- Reduces pick and place cost through integrated passive components
- Replaces general-purpose transistors in digital applications
Applications
- Low current peripheral driver
- Control of IC inputs
- Replacement of general-purpose transistors in digital applications
Procurement Notes
Verify the specific manufacturer status before procurement, as the product was originally released under NXP Semiconductors branding. Confirm that the SOT666 package variant matches the required PCB footprint. Ensure compliance with RoHS standards if applicable to the target assembly process. Check for any obsolescence notices or lifecycle changes directly from the supplier.
Selection Notes
Select this component when designing circuits requiring dual PNP switching with integrated base drive resistors. The fixed 100 kΩ bias resistors eliminate external resistor selection but limit flexibility in base current adjustment. Verify that the -50 V collector-emitter voltage rating meets the system's maximum operating voltage requirements.
Part Context
The PEMB24 belongs to the family of resistor-equipped transistors alongside the PUMB24 (SOT363 package). It serves as a compact solution for digital logic interfaces where space saving and simplified bill of materials are priorities. The device complements other discrete semiconductors used in automotive and industrial control systems.
Replacement Considerations
The PEMD24 is listed as the NPN/NPN complement within the same product family. Designers should verify pinout compatibility and electrical symmetry if substituting with complementary devices or similar resistor-equipped transistor families.
