NXP Semiconductors PMEM4010PD,115

Overview

PMEM4010PD from NXP Semiconductors is a monolithic PNP transistor/Schottky diode module in a single SOT457 (SC-74) surface-mount package. It integrates a high-current PNP transistor with V_CEsat ≤ 310 mV at −1 A and a guard-ring-protected Schottky diode with VF ≤ 550 mV at 1 A, enabling compact DC/DC converter and inductive load driver designs.

For engineers reviewing the PMEM4010PD datasheet, PMEM4010PD pinout, PMEM4010PD application, or PMEM4010PD equivalent, key selection criteria include its dual-function integration, low saturation voltage, ultra-fast diode switching, thermal resistance of 208 K/W, and compatibility with reverse polarity protection and freewheeling circuits requiring <1 cm² PCB area.

Technical Context

The PMEM4010PD combines two electrically independent semiconductor elements - a planar PNP bipolar transistor and a planar Schottky barrier diode - on a single die within a thermally optimized SOT457 package. The transistor features h_FE = 160–800 (IC = −1 mA to −1 A), while the diode delivers IF = 1 A continuous with IR ≤ 50 µA at VR = 15 V and Cd = 19–25 pF at VR = 5 V.

Its integrated guard ring protects the Schottky junction against edge breakdown under transient stress, and the shared collector pad (Pin 6) and cathode (Pin 3) enable efficient thermal coupling to PCB copper. Pin 2 is internally unconnected - confirmed by datasheet pinning table and outline diagram.

Key Specifications

FAQ

What is the maximum continuous collector current rating for the PMEM4010PD?

The PMEM4010PD has a maximum continuous collector current (I_C) rating of −1 A, as specified in the Absolute Maximum Ratings table under "collector current (DC)". This rating assumes operation within ambient temperature limits (−65 °C to +125 °C) and proper PCB thermal management - specifically, a 1 cm² tin-plated copper pad for the collector (Pin 6) to maintain junction temperature below 150 °C.

Is Pin 2 of the PMEM4010PD electrically connected internally?

No, Pin 2 of the PMEM4010PD is explicitly designated as "not connected" in the official NXP datasheet pinning table and schematic symbol. It has no internal bond wire or die connection and must remain unconnected in the PCB layout - neither tied to ground nor used for signal routing - to avoid unintended parasitic coupling or mechanical stress on the leadframe.

Can the PMEM4010PD be used as a standalone Schottky diode without using the transistor?

Yes, the PMEM4010PD can be used solely as a Schottky diode by connecting Pin 4 (anode) and Pin 3 (cathode) into the circuit while leaving Pins 1, 5, and 6 unconnected or appropriately biased. The diode section operates independently with VR = 20 V, IF = 1 A, and VF ≤ 550 mV at 1 A - verified in the Characteristics section. Pin 2 must remain floating.

What is the thermal resistance from junction to ambient (R_{th j-a}) for the PMEM4010PD?

The thermal resistance from junction to ambient (R_{th j-a}) for the PMEM4010PD is 208 K/W, measured under standard test conditions: device mounted on a single-sided, tin-plated PCB with a 1 cm² copper pad for the collector (Pin 6). This value applies only in free-air convection and decreases significantly with added copper area or forced airflow.

Does the PMEM4010PD include any built-in protection features beyond the guard ring?

Yes, the Schottky diode portion of the PMEM4010PD includes an integrated guard ring for edge termination and stress protection, as explicitly stated in the Features and Description sections. No additional protection features - such as overvoltage clamping, thermal shutdown, or ESD structures - are documented for the PMEM4010PD. System-level protection must be implemented externally per application requirements.
