Product details

Overview

94-2436PBF from Infineon Technologies is an N-channel enhancement-mode MOSFET in DPAK (TO-252) package, rated for 55 V V_DS, 30 A continuous drain current at T_C = 25°C, and R_DS(on) ≤ 22 mΩ at V_GS = 10 V. It serves as a main power switch in DC-DC synchronous buck converters for industrial power supplies.

For engineers reviewing the 94-2436PBF datasheet, 94-2436PBF pinout, 94-2436PBF application, or 94-2436PBF equivalent, key selection criteria include its low conduction loss at 12 V gate drive, thermal performance in surface-mount layouts, and suitability for high-efficiency 48 V input-to-12 V output conversion stages.

Technical Context

This MOSFET employs trench-gate silicon technology optimized for fast switching with reduced gate charge (Q_g = 32 nC typical) and low reverse recovery charge (Q_rr = 37 nC). Its body diode exhibits soft recovery characteristics critical for minimizing voltage overshoot in synchronous rectification.

The device is specified for operation up to T_J = 175°C and features 100% avalanche-rated ruggedness (E_AS = 120 mJ), enabling reliable use in unregulated input or load-dump transient conditions without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum blocking voltage compatible with 48 V nominal bus systems including surge margins.
I_D (continuous)	30 A at T_C = 25°C - Supports ≥25 A steady-state output in compact DPAK thermal layout with 2 oz copper and 2 thermal vias.
R_DS(on)	≤22 mΩ at V_GS = 10 V - Enables <0.7 W conduction loss at 15 A, reducing heatsink requirements.
Q_g	32 nC typical - Allows efficient 500 kHz switching with standard gate drivers (e.g., IR2110) without excessive driver power loss.
E_AS	120 mJ - Withstands single-pulse inductive energy events up to 120 mJ without failure, eliminating need for external clamping in many SMPS designs.
Q_rr	37 nC - Limits cross-conduction losses during dead-time in synchronous buck topologies, improving efficiency by ~0.8% at full load.

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for enhanced thermal dissipation; standard 3-pin configuration (G-D-S) with drain connected to tab.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Current return path for channel conduction	Connected to power ground plane; requires low-inductance routing to minimize switching noise coupling.
Pin 2 (Gate)	Control electrode for channel formation	High-impedance input requiring RC snubber (10 Ω + 100 pF) near device to damp ringing during fast transitions.
Pin 3 (Drain)	Main current-carrying terminal (connected to tab)	Tab soldered to PCB copper pour acts as primary heat sink; must be isolated from other nets per creepage/clearance rules.

Key Features

Feature	Design Value
Trench MOSFET architecture	Enables lower R_DS(on) × Q_g figure-of-merit than planar devices, improving trade-off between conduction and switching loss.
100% EAS tested	Guarantees robustness against inductive turn-off transients without derating, simplifying reliability validation.
Soft-recovery body diode	Reduces EMI generation and voltage spikes during freewheeling, lowering filter component count in EMI-compliant designs.
Lead-free and RoHS compliant	Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1), enabling standard reflow without baking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP30NF55	R_DS(on) = 28 mΩ (higher), Q_g = 45 nC (higher), TO-220 package	Requires heatsink due to higher R_DS(on) and through-hole mounting; unsuitable for space-constrained layouts	Select only if board redesign for TO-220 footprint is acceptable and thermal budget allows +0.35 W conduction loss.
IRFZ44NPBF	R_DS(on) = 28 mΩ, Q_rr not specified, TO-220 package	Lacks documented soft-recovery body diode; may require external snubber in synchronous rectification	Use only in non-synchronous or low-frequency (<100 kHz) applications where Q_rr impact is negligible.

Compared with STP30NF55 and IRFZ44NPBF, 94-2436PBF delivers superior power density and EMI performance in surface-mount synchronous buck converters, while its DPAK package enables automated assembly and better thermal management on standard PCBs.

FAQ

What is the maximum junction temperature for continuous operation?

The 94-2436PBF is rated for continuous operation up to T_J = 175°C. This allows full 30 A current capability when the case temperature is maintained at or below 25°C using adequate PCB copper area and thermal vias. Derating curves in the official Infineon datasheet specify linear reduction to 15 A at T_C = 100°C.

Does this MOSFET support 5 V gate drive?

No. The 94-2436PBF is a standard-threshold MOSFET requiring ≥10 V gate drive for guaranteed R_DS(on) ≤ 22 mΩ. At 5 V V_GS, R_DS(on) rises to approximately 55 mΩ, increasing conduction loss by over 150%. It is not logic-level compatible.

Can it replace IRFZ44N in existing designs?

Direct replacement is not recommended. While both are N-channel MOSFETs, 94-2436PBF uses DPAK packaging versus TO-220 for IRFZ44N, requiring PCB layout change. Additionally, its lower Q_rr and soft-recovery diode alter switching behavior-gate drive strength and dead-time settings may need adjustment to avoid shoot-through.

Is the drain tab electrically isolated from the PCB ground plane?

No. The drain (Pin 3) is internally connected to the exposed metal tab, which must be soldered to a dedicated drain copper pour. That pour must remain electrically isolated from all other nets-including system ground-unless the circuit topology intentionally references drain as the common node (e.g., high-side switch configuration).
