Product details
Overview
DFL1504S-E3/77 from Vishay Siliconix is a logic-level N-channel power MOSFET in TO-220AB package, rated for 200 V VDS, 5.2 A continuous drain current at TC = 25 °C, and 0.80 Ω RDS(on) at VGS = 5 V. It supports fast switching, repetitive avalanche operation, and is optimized for DC-DC converters, motor control, and industrial power supplies.
For engineers reviewing the DFL1504S-E3/77 datasheet, DFL1504S-E3/77 pinout, DFL1504S-E3/77 application, or DFL1504S-E3/77 equivalent, key selection criteria include its logic-level gate drive (VGS(th) = 1.0–2.0 V), low RDS(on) at 4–5 V, 16 nC total gate charge, and TO-220AB thermal performance (RthJC = 2.5 °C/W).
Technical Context
This MOSFET employs third-generation planar silicon technology with ruggedized die design for enhanced avalanche robustness and dynamic dV/dt immunity (5.0 V/ns peak diode recovery). Its gate threshold voltage range (1.0–2.0 V) ensures reliable turn-on with standard 3.3 V or 5 V logic drivers.
The device integrates a fast-recovery body diode (trr = 180–270 ns, Qrr = 1.1–1.7 μC) and features low parasitic inductance (LD = 4.5 nH, LS = 7.5 nH), supporting high-frequency hard-switching topologies without excessive voltage overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - supports input voltages up to 160 V DC in buck converters or 100 V AC rectified rails |
| RDS(on) @ VGS = 5 V | 0.80 Ω - enables ≤2.1 W conduction loss at 5.2 A, suitable for thermally constrained PCB layouts |
| Qg | 16 nC - determines gate driver current requirement (~1.6 mA average for 1 MHz switching) |
| ID (continuous, TC = 25 °C) | 5.2 A - defines maximum steady-state load current with heatsink |
| EAS | 125 mJ - allows unclamped inductive switching without failure under defined test conditions |
| trr | 180–270 ns - limits reverse recovery losses in synchronous rectification and freewheeling paths |
Pinout & Package
DFL1504S-E3/77 uses the industry-standard TO-220AB package with isolated tab (drain-connected), offering low thermal resistance (RthJC = 2.5 °C/W) and mechanical compatibility with common heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control terminal | Receives logic-level voltage (≥4 V) to fully enhance channel; requires <16 nC charge for full turn-on |
| D (Drain) | High-side power output | Connected to internal die substrate and metal tab; must be electrically isolated from heatsink unless referenced to system ground |
| S (Source) | Power return/reference node | Serves as local ground reference for gate drive; source inductance (7.5 nH) impacts switching stability in high-dI/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) = 1.0–2.0 V enables direct interface with 3.3 V microcontrollers without level-shifting circuitry |
| Repetitive avalanche rated | Rated for IAR = 5.2 A and EAR = 5.0 mJ, allowing safe operation during transient overloads in inductive loads |
| Fast switching | td(on) = 4.2 ns, tr = 31 ns, td(off) = 18 ns, tf = 17 ns - supports >500 kHz PWM in SMPS designs |
| Low gate charge | Qgd = 9.6 nC dominates Miller region; enables reduced gate driver power dissipation and faster voltage transitions |
Applications
| DC-DC Buck Converter | Brushed DC Motor Driver |
|---|---|
Use Scenario: Step-down regulation from 100–160 V DC input to 12–24 V output in industrial power modules. IC Role / Device Role / Timing Role: High-side synchronous switch operating at 100–300 kHz with forced commutation. Use Value: 0.80 Ω RDS(on) minimizes conduction loss at 5 A load; 125 mJ EAS absorbs energy during inductor current interruption. | Use Scenario: H-bridge half-bridge leg controlling 24 V, 3–5 A brushed motors in factory automation actuators. IC Role / Device Role / Timing Role: Low-side switching element with fast turn-off (tf = 17 ns) to reduce shoot-through risk during direction reversal. Use Value: Logic-level VGS(th) ensures full enhancement using 3.3 V MCU GPIO; body diode trr ≤ 270 ns limits freewheeling losses. |
| AC-DC Front-End Switch | Industrial LED Driver |
Use Scenario: Active clamp or auxiliary switch in flyback or forward converters accepting 85–265 V AC input. IC Role / Device Role / Timing Role: Clamping switch triggered synchronously with primary MOSFET to recycle leakage energy. Use Value: 200 V VDS rating accommodates reflected voltage spikes; dV/dt immunity of 5.0 V/ns prevents false triggering during high-slew transients. | Use Scenario: Constant-current switching element in 48 V, 1–2 A LED string drivers for high-bay lighting. IC Role / Device Role / Timing Role: PWM-controlled current regulator modulating LED brightness at 1–10 kHz. Use Value: Low Qg (16 nC) reduces gate driver power consumption; TO-220AB package enables direct mounting to aluminum extrusion heatsinks. |
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 |
|---|---|---|---|
| IRL620PbF | Same die, Pb-free termination only; identical RDS(on), Qg, and avalanche ratings | No functional difference; RoHS-compliant variant for lead-free assembly | Select when Pb-free compliance is mandatory per IPC-J-STD-020 or customer specification |
| STP5NK60ZFP | 600 V VDS, higher RDS(on) (1.2 Ω), lower ID (4.5 A), different gate charge profile (Qg = 23 nC) | Better suited for higher-voltage flyback primary switches; not logic-level (VGS(th) = 2–4 V) | Choose only if 600 V rating is required and gate drive voltage ≥10 V is available |
Compared with IRL620PbF and STP5NK60ZFP, DFL1504S-E3/77 offers optimal balance of logic-level drive, 200 V rating, and thermal efficiency in TO-220AB for mid-voltage industrial switching-making it preferred for space-constrained 3.3 V/5 V control systems where avalanche ruggedness and fast body diode recovery are critical.

FAQ
What is the maximum continuous drain current for DFL1504S-E3/77 at 100 °C case temperature?
The DFL1504S-E3/77 supports 3.3 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220AB package and must be verified against actual board layout, heatsink interface, and ambient conditions. Designers should consult Fig. 9 (Maximum Drain Current vs. Case Temperature) in the Vishay S21-1046 datasheet for interpolation across temperatures. The DFL1504S-E3/77 maintains RDS(on) stability up to 150 °C junction temperature.
Does DFL1504S-E3/77 have a built-in body diode, and what are its key parameters?
Yes, the DFL1504S-E3/77 integrates a monolithic body diode with typical forward voltage VSD = 1.8 V at IS = 5.2 A and TJ = 25 °C. Its reverse recovery time trr is 180–270 ns, and reverse recovery charge Qrr is 1.1–1.7 μC under standardized test conditions (IF = 5.2 A, dI/dt = 100 A/μs). These values are confirmed in the Drain-Source Body Diode Characteristics section of the Vishay datasheet for DFL1504S-E3/77.
Is DFL1504S-E3/77 compatible with 3.3 V microcontroller GPIOs for direct gate driving?
Yes, DFL1504S-E3/77 is explicitly designed for logic-level operation with VGS(th) ranging from 1.0 V to 2.0 V, ensuring full enhancement at VGS = 4.0 V (RDS(on) = 1.0 Ω) and VGS = 5.0 V (RDS(on) = 0.80 Ω). A 3.3 V GPIO can reliably drive the gate, though designers should verify gate charge (16 nC) and switching speed requirements against driver capability. The DFL1504S-E3/77 datasheet confirms this behavior in the Static Specifications table.
What is the thermal resistance from junction to case (RthJC) for DFL1504S-E3/77?
The junction-to-case thermal resistance RthJC for DFL1504S-E3/77 is 2.5 °C/W maximum, as stated in the Thermal Resistance Ratings table of the Vishay S21-1046 datasheet. This value applies to the drain-connected metal tab and assumes proper mounting to a flat, greased heatsink surface. The DFL1504S-E3/77's low RthJC enables efficient heat transfer in high-power-density applications such as industrial motor drives and LED drivers.
Can DFL1504S-E3/77 be used in avalanche-mode operation, and what are its rated limits?
Yes, DFL1504S-E3/77 is repetitively avalanche-rated with IAR = 5.2 A and EAR = 5.0 mJ, and single-pulse avalanche energy EAS = 125 mJ. These ratings assume specific test conditions: VDD = 50 V, starting TJ = 25 °C, L = 6.9 mH, Rg = 25 Ω. The DFL1504S-E3/77 datasheet provides avalanche waveforms and derating curves (Fig. 12c) to guide safe implementation in inductive switching circuits.
