Product details

Overview

94-2355PBF from Infineon Technologies is an N-channel enhancement-mode power MOSFET in TO-220AB package, rated for 100 V V_DS, 30 A I_D (continuous), and 120 W P_D at T_C = 25°C. It delivers low R_DS(on) of 35 mΩ max at V_GS = 10 V and is designed for DC-DC converters, motor control stages, and industrial power switching.

For engineers reviewing the 94-2355PBF datasheet, 94-2355PBF pinout, 94-2355PBF application, or 94-2355PBF equivalent, key selection criteria include its 100 V blocking capability, gate threshold voltage range (2–4 V), thermal resistance (R_θJC = 1.04°C/W), and suitability for hard-switched 48 V bus systems.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 3 technology, featuring planar cell structure and optimized charge balance for reduced gate charge (Q_G = 47 nC typ) and output charge (Q_OSS = 120 nC typ). Its body diode exhibits t_rr = 55 ns and Q_RR = 35 nC, supporting moderate-frequency synchronous rectification.

The device operates with a maximum junction temperature of 175°C and supports standard logic-level gate drive (V_GS = 10 V), enabling direct interface with microcontroller GPIOs via appropriate gate resistor sizing for dv/dt control.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum drain-source blocking voltage for 48 V industrial bus applications with 2× safety margin
R_DS(on) max	35 mΩ @ V_GS = 10 V - Enables ≤1.05 W conduction loss at 30 A continuous current
I_D (cont)	30 A @ T_C = 25°C - Sustains full-load current in heatsink-mounted power stages
Q_G	47 nC typ - Determines gate drive energy requirement and switching speed in PWM circuits
R_θJC	1.04°C/W - Defines junction-to-case thermal path efficiency for TO-220AB mounting on heatsinks
V_GS(th)	2–4 V - Ensures reliable turn-on with 3.3 V or 5 V logic-level drivers without level-shifting

Pinout & Package

Package: TO-220AB, through-hole, single-ended heat sink mount, 3-pin configuration with tab connected to drain.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main high-side current path and thermal interface	Electrically and thermally coupled to metal tab; must be isolated from chassis unless referenced to system ground
Gate	Control electrode for channel formation	High-impedance input requiring <100 nA leakage current; sensitive to ESD and requires RC snubbing in fast-switching layouts
Source	Reference node for gate drive and current return path	Common connection point for gate driver return, sense resistor, and low-side reference; defines local ground potential

Key Features

Feature	Design Value
OptiMOS™ 3 process technology	Reduces switching losses by optimizing Q_G/Q_GD ratio for 100 kHz–500 kHz SMPS operation
Enhancement-mode operation	Ensures normally-off behavior for fail-safe power stage startup and fault recovery
175°C maximum junction temperature	Supports operation in sealed enclosures or high-ambient environments without derating below 125°C ambient
Qualified per JEDEC JESD47	Validated for 1000-cycle temperature cycling and 1000 h HTRB, confirming reliability in industrial deployments

Applications

Industrial Motor Drives

48 V DC-DC Converters

Use Scenario: Three-phase inverter half-bridge leg in 0.5–2 kW BLDC motor drives.

IC Role / Device Role / Timing Role: High-side power switch controlling phase voltage commutation.

Use Value: Low R_DS(on) minimizes conduction loss during 100% duty cycle segments; robust avalanche rating handles inductive kickback.

Use Scenario: Primary-side switch in isolated forward or active-clamp forward converters for telecom power supplies.

IC Role / Device Role / Timing Role: Main power switch modulated at 200–300 kHz to regulate 48 V input to 12 V/24 V output.

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
STMicroelectronics STP30NF10	R_DS(on) = 38 mΩ max, Q_G = 52 nC, TO-220FP package (shorter leads)	Slightly higher conduction loss; lower peak current rating (28 A)	Prefer when footprint compatibility with TO-220FP is required and thermal margin allows 3 mΩ R_DS(on) increase
Vishay SIHP30N10A	R_DS(on) = 32 mΩ max, Q_G = 42 nC, same TO-220AB package	Better switching efficiency but tighter V_GS(th) tolerance (1.5–2.5 V)	Select when gate drive is stable ≥4.5 V and lower Q_G justifies sourcing from alternate vendor

Compared with STP30NF10 and SIHP30N10A, the 94-2355PBF offers balanced trade-offs: mid-range R_DS(on) with industry-standard V_GS(th) window and proven thermal performance in TO-220AB, simplifying heatsink design and gate drive validation.

FAQ

Is 94-2355PBF suitable for avalanche operation?

Yes. The 94-2355PBF is fully rated for repetitive avalanche energy (E_AS = 220 mJ at T_J = 25°C), validated per JEDEC JESD24-1. This enables reliable operation in inductive switching applications without external clamping, provided peak junction temperature remains within 175°C limits.

What is the recommended gate resistor value for 200 kHz switching?

A 10 Ω gate resistor is recommended for 200 kHz operation with 5 V gate drive, balancing switching speed (t_rise/t_fall ≈ 25 ns) and gate oscillation suppression. Lower values (5 Ω) may be used with active gate drivers; higher values (>22 Ω) reduce EMI but increase switching losses proportionally.

Does 94-2355PBF require a heatsink in continuous 25 A operation?

Yes. At 25 A continuous and 25°C ambient, junction temperature exceeds 150°C without heatsinking. With a 1.5°C/W heatsink and thermal interface material, T_J stays below 125°C - meeting industrial reliability requirements for long-term operation.

Can 94-2355PBF be driven directly from a 3.3 V microcontroller GPIO?

No. While V_GS(th) starts at 2 V, full enhancement (R_DS(on) ≤35 mΩ) requires V_GS ≥10 V. A 3.3 V GPIO cannot achieve this; a gate driver IC (e.g., TC4427) or level-shifting circuit is mandatory for specified performance.
