PUMB3HF Equivalent & Substitute Parts

Part Overview

The PUMB3HF is a pre-biased dual PNP bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in a 6-TSSOP surface mount package. This device integrates two PNP transistors with internal base resistors, designed for switching and amplification applications requiring 50V collector-emitter breakdown voltage and 100mA maximum collector current.

The PUMB3HF carries an obsolete product status. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PUMB3HF is determined by strict equivalence across the following critical parameters:

Electrical Characteristics:

• Transistor configuration: 2 PNP pre-biased dual topology
• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 50V
• Base resistor value: 4.7kOhms
• DC current gain (hFE): 200 minimum at 1mA, 5V
• Saturation voltage: 100mV maximum at specified bias conditions
• Collector cutoff current: 100nA maximum
• Transition frequency: 180MHz

Mechanical & Environmental Characteristics:

• Package type: 6-TSSOP (SC-88, SOT-363)
• Mounting: Surface mount
• RoHS compliance: ROHS3 compliant
• Moisture sensitivity: MSL 1

A substitute part must match all electrical parameters and maintain identical package specifications to ensure direct replacement without circuit redesign or PCB layout modification.
