PEMB9,115

Overview

The PEMB9,115 is a PNP/PNP double Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates two PNP transistors with built-in bias resistors in an ultra-small SOT666 surface-mounted package. The device supports a collector-emitter voltage of -50 V and an output current of -100 mA per transistor. Key electrical parameters include a typical DC current gain (hFE) of 100 at -5 mA and -5 V, a maximum collector-base cut-off current of 1 µA at -30 V, and a total power dissipation of 300 mW. The internal bias network consists of R1 = 10 kΩ and R2 = 47 kΩ.

Feature Summary

• Integrates dual PNP transistors with fixed bias resistors to reduce component count
• Simplifies circuit design for digital applications and interface circuits
• Ultra-small flat lead SOT666 package suitable for space-constrained designs

Applications

• Low current peripheral driver
• Controlling IC inputs
• Replacing general-purpose transistors in digital applications

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as indicated on distributor listings. Confirm that the procurement source provides the official Nexperia datasheet for the PEMB9 series to ensure compliance with the stated electrical characteristics and absolute maximum ratings before finalizing orders.

Selection Notes

Select this component when a compact solution for driving low-current loads or interfacing with logic inputs is required. The integrated bias resistors eliminate the need for external base resistors, simplifying the schematic. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the thermal constraints of the SOT666 package are respected during operation.

Part Context

The PEMB9 belongs to the PEMB9 family of PNP/PNP resistor-equipped double transistors. It serves as the PNP complement to the PEMD9 (NPN/PNP) and PEMH9 (NPN/NPN) variants. This family is designed to replace discrete transistor-resistor combinations in digital switching and amplification circuits, offering a standardized footprint and pinout for easy design integration.

Replacement Considerations

Direct functional replacements within the same package and specification range include the PEMD9 and PEMH9 from the same manufacturer family. Verify that any substitute maintains the -50 V voltage rating, 100 mA current capability, and compatible bias resistor values to ensure circuit compatibility without redesign.
