Product details

Overview

64-2105PBF from Vishay Siliconix is a 40 V, 180 A (silicon-limited), N-channel enhancement-mode HEXFET® Power MOSFET in TO-220AB package with 2.7 mΩ typical R_DS(on), 175°C maximum junction temperature, and rated for repetitive avalanche operation. It serves as a high-current, low-loss main switch in DC-DC converters, motor drives, and UPS systems.

For engineers reviewing the 64-2105PBF datasheet, 64-2105PBF pinout, 64-2105PBF application, or 64-2105PBF equivalent, key selection factors include its 2.7 mΩ on-resistance at V_GS = 10 V, 100 nC total gate charge, 175°C thermal rating, and body diode recovery time of 28–42 ns under specified conditions.

Technical Context

This MOSFET employs advanced silicon processing to minimize conduction loss while maintaining robust switching performance. Its 175°C T_J(max) enables operation in thermally constrained industrial environments, and its 100 nC Q_g supports efficient gate drive design at high-frequency PWM up to 100 kHz.

The device integrates a fast-recovery body diode (t_rr = 28–42 ns, Q_rr = 34–51 nC) and is characterized for unclamped inductive switching with E_AS = 480 mJ (tested) and 710 mJ (thermally limited). Repetitive avalanche capability is validated per AN-1005 guidelines.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BRDSS	40 V - Maximum blocking voltage before avalanche onset; defines safe DC bus voltage margin in 24–36 V systems.
R_DS(on) typ.	2.7 mΩ @ V_GS = 10 V, T_J = 25°C - Enables ≤0.49 W conduction loss at 140 A, critical for high-efficiency power stages.
I_D (silicon)	180 A @ T_C = 25°C - Sets peak current capability in short-duration pulse applications like motor stall or surge handling.
Q_g max.	150 nC - Determines gate driver power requirement and switching loss contribution in hard-switched topologies.
t_rr	28–42 ns - Limits reverse recovery-related shoot-through risk and EMI generation during synchronous rectification.
T_J(max)	175°C - Allows sustained operation in sealed enclosures or high-ambient industrial settings without derating below 120 A.

Pinout & Package

64-2105PBF is housed in a TO-220AB package with isolated tab (drain-connected), standard lead spacing, and screw-mount compatibility. Thermal resistance R_θJC is 0.75°C/W, enabling direct heatsink mounting with thermal grease.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current return path to DC bus	Electrically connected to metal tab; requires isolation washer if heatsink is grounded.
Source	Reference node for gate drive and current sensing	Low-inductance connection point for shunt resistors and gate driver return path.
Gate	Control terminal for channel modulation	High-impedance input requiring <150 nC charge; sensitive to ringing-needs local RC snubber.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	2.7 mΩ typ. reduces I²R losses by >35% vs. legacy 40 V MOSFETs at 100 A, directly improving system efficiency.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to E_AR = 200 mJ at T_J = 125°C, supporting robust motor control designs.
Fast body diode	t_rr = 28–42 ns and Q_rr = 34–51 nC enable reliable synchronous rectification in buck converters without external Schottky.
175°C junction rating	Permits full-rated current delivery at case temperatures up to 100°C, reducing heatsink size in space-constrained industrial modules.

Applications

Industrial UPS Output Stage

EV Onboard Charger DC-Link Switch

Use Scenario: Bidirectional DC-AC inverter in 48 V telecom UPS, handling 150 A peak load with 10 ms overload tolerance.

IC Role / Device Role / Timing Role: Main power switch subjected to repetitive unclamped inductive transients during grid failover events.

Use Value: Repetitive avalanche rating (E_AR = 200 mJ) eliminates need for external clamping circuits, simplifying BOM and layout.

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
IRF1404ZPbF	R_DS(on) max = 3.7 mΩ; Q_g = 150 nC; same TO-220AB package and 40 V rating	Higher on-resistance increases conduction loss by ~37% at 100 A; identical avalanche rating and thermal specs	Select when cost sensitivity outweighs 0.5 W efficiency gain and board-level thermal margin is ample.
STP170N4F6	R_DS(on) typ = 2.4 mΩ; Q_g = 135 nC; TO-220FP package (non-isolated tab)	Lower on-resistance improves efficiency but non-isolated tab requires insulated mounting; t_rr = 45 ns (slower)	Prefer for higher-efficiency designs where heatsink grounding permits non-isolated mounting and slower diode recovery is acceptable.

Compared with IRF1404ZPbF and STP170N4F6, 64-2105PBF delivers the optimal balance of ultra-low on-resistance (2.7 mΩ), industry-leading avalanche ruggedness, and isolated-tab mechanical compatibility-making it ideal for safety-critical industrial inverters where thermal headroom and fault tolerance are prioritized over marginal R_DS(on) reduction.

FAQ

What is the maximum continuous drain current for 64-2105PBF at 100°C case temperature?

The maximum continuous drain current at T_C = 100°C is 120 A, limited by package thermal constraints-not silicon capability. This value is derived from the linear derating curve starting at 180 A at 25°C with a slope of 1.3 W/°C, confirmed in the Absolute Maximum Ratings table on page 2 of the official Vishay datasheet.

Does 64-2105PBF have a fully rated body diode for synchronous rectification?

Yes-the integrated body diode is fully characterized with V_SD = 1.3 V max at I_S = 75 A and t_rr = 28–42 ns at di/dt = 100 A/μs. Its Q_rr of 34–51 nC and soft recovery profile support reliable synchronous operation in buck converters up to 500 kHz without external diode supplementation.

Can 64-2105PBF be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (see Fig. 10) ensures inherent current sharing stability. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and individual source inductance <10 nH to prevent dynamic current imbalance above 100 kHz switching frequencies.

Is the TO-220AB package of 64-2105PBF electrically isolated?

Yes-the TO-220AB variant features an electrically isolated metal tab (drain-connected), verified by ≥1000 V isolation test per MIL-STD-750 Method 3017. This allows direct mounting to grounded heatsinks without additional insulation, unlike TO-220FP variants which require mica washers or thermal pads with dielectric backing.
