Product details
Overview
IRLD120PBF from Vishay Siliconix is a logic-level N-channel power MOSFET in HVMDIP (4-pin DIP) package, rated for 100 V VDS, 1.3 A continuous drain current at 25 °C, and 0.27 Ω RDS(on) at VGS = 5 V. It features repetitive avalanche rating, 175 °C operating junction temperature, and dual-drain thermal path for up to 1 W power dissipation - used in low-power DC-DC converters and relay drivers.
For engineers reviewing the IRLD120PBF datasheet, IRLD120PBF pinout, IRLD120PBF application, or IRLD120PBF equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1.0–2.0 V), dV/dt ruggedness (5.5 V/ns), and HVMDIP through-hole mountability with stackable end geometry.
Technical Context
This device belongs to Vishay's third-generation high-voltage MOSFET family optimized for fast switching and ruggedized operation. Its dynamic dV/dt rating and repetitive avalanche capability (IAR = 1.3 A, EAR = 0.13 mJ) enable reliable operation under inductive load switching transients without external snubbers.
The HVMDIP package integrates dual drain terminals as a thermal link to the PCB, supporting conduction-cooled dissipation up to 1 W. Gate charge parameters (Qg = 12 nC, Qgd = 7.1 nC) indicate moderate switching loss profile suitable for <100 kHz hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports input rails up to 80 V DC with margin for inductive kick and ripple. |
| RDS(on) @ VGS = 5 V | 0.27 Ω - enables ≤0.4 W conduction loss at 1.3 A, suitable for low-duty-cycle loads. |
| Qg | 12 nC - determines gate drive strength requirement; compatible with standard logic-level drivers (e.g., TC4420). |
| TJ max | 175 °C - allows operation in sealed enclosures or high-ambient industrial environments without derating below 100 °C ambient. |
| dV/dt rating | 5.5 V/ns - suppresses false turn-on during high-slew-rate noise events in motor or solenoid drive circuits. |
| ID continuous @ TA = 100 °C | 0.94 A - defines usable current in thermally constrained PCB layouts with limited copper area. |
Pinout & Package
HVMDIP (High-Voltage Mini-DIP) package: 4-pin through-hole, 0.1" pin pitch, dual drain leads (D1/D2), single gate (G), single source (S). Molded plastic body with exposed drain pads for thermal conduction to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1, D2 | Drain (dual parallel) | Shared high-side switch node; both pins electrically identical and thermally coupled to PCB copper for enhanced heat spreading. |
| G | Gate | Logic-level control input; threshold voltage 1.0–2.0 V enables direct drive from 3.3 V or 5 V microcontrollers. |
| S | Source | Power return reference; connects to system ground or low-side shunt; body diode anode. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 4.0 V (RDS(on) = 0.38 Ω), eliminating need for gate boosters in 3.3 V/5 V control systems. |
| Repetitive avalanche rated | Rated for 1.3 A repetitive avalanche current and 0.13 mJ energy - enables robust unclamped inductive switching without external protection. |
| Dual drain thermal path | Two drain pins reduce thermal resistance to PCB; supports 1 W dissipation with minimal copper area (≥1 in² 2 oz Cu recommended). |
| Dynamic dV/dt immunity | 5.5 V/ns rating prevents spurious turn-on during fast voltage transients common in relay coil or solenoid de-energization. |
Applications
| DC-DC Converter Primary Switch | Low-Power Relay Driver |
|---|---|
Use Scenario: Step-down converter in battery-powered instrumentation with 24 V input and 5 V/1 A output. IC Role / Device Role / Timing Role: High-side synchronous rectifier switch operating at 50 kHz with duty cycle modulation. Use Value: Low RDS(on) (0.27 Ω) minimizes conduction loss; logic-level gate ensures full enhancement using MCU PWM output without level shift. |
Use Scenario: Solid-state replacement for electromechanical relays controlling 12 V/500 mA HVAC actuators. IC Role / Device Role / Timing Role: Low-side load switch with integrated body diode handling inductive flyback. Use Value: Repetitive avalanche rating absorbs 690 mJ single-pulse energy, eliminating external flyback diode in cost-sensitive designs. |
| LED Constant-Current Driver | Industrial Sensor Power Switch |
Use Scenario: Dimmable LED string driver in building automation panels with 36 V bus and PWM dimming. IC Role / Device Role / Timing Role: Low-side current sink switch modulated at 1–10 kHz to regulate average LED current. Use Value: 175 °C TJ rating permits operation inside sealed metal enclosures; Qg = 12 nC enables clean PWM edges without gate ringing. |
Use Scenario: Remote sensor node powered via 24 V PoE-derived supply, requiring on/off control of analog front-end circuitry. IC Role / Device Role / Timing Role: Always-on power switch enabling/disabling entire sensor subsystem under MCU command. Use Value: End-stackable HVMDIP footprint simplifies manual assembly and rework; Pb-free (PbF) marking confirms RoHS compliance for industrial deployment. |
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 |
|---|---|---|---|
| IRLD024PBF | VDS = 60 V, RDS(on) = 0.13 Ω @ 5 V, lower voltage rating and higher current capability. | Not suitable for 80–100 V bus applications; preferred where input voltage ≤48 V and lower on-resistance is critical. | Select IRLD024PBF only when system VIN < 50 V and RDS(on) reduction outweighs voltage margin loss. |
| FQP30N06L | VDS = 60 V, RDS(on) = 0.035 Ω @ 5 V, TO-220 package, no avalanche rating. | Higher thermal mass but requires heatsink above ~0.5 W; lacks dV/dt and avalanche ruggedness for inductive loads. | Choose FQP30N06L for high-current linear-mode or low-frequency switching where ruggedness is secondary to conduction loss. |
Compared with IRLD024PBF and FQP30N06L, the IRLD120PBF uniquely balances 100 V rating, logic-level drive, and certified repetitive avalanche performance in a compact, stackable DIP package - making it the only option among the three qualified for unclamped inductive switching at >60 V.

FAQ
What is the maximum continuous drain current for IRLD120PBF at 100 °C ambient temperature?
The IRLD120PBF supports 0.94 A continuous drain current at TA = 100 °C, as specified in the Absolute Maximum Ratings table. This value accounts for thermal derating due to reduced heat dissipation at elevated ambient temperatures and assumes adequate PCB copper area for thermal conduction through the dual drain leads.
Does IRLD120PBF require a gate resistor for safe operation?
While not strictly required, a gate resistor (typically 10–47 Ω) is recommended for IRLD120PBF to dampen ringing caused by gate loop inductance and prevent oscillation during fast switching. The device's Qg = 12 nC and moderate Ciss = 490 pF make it susceptible to overshoot without controlled gate drive impedance.
Can IRLD120PBF be used in avalanche mode repeatedly?
Yes, the IRLD120PBF is explicitly rated for repetitive avalanche operation with IAR = 1.3 A and EAR = 0.13 mJ per pulse, provided pulse width and duty cycle remain within limits defined by junction temperature rise. This capability is validated per Figure 12 test conditions and eliminates need for external clamping in many inductive load circuits.
What is the body diode forward voltage of IRLD120PBF at 1.3 A?
The body diode forward voltage (VSD) of IRLD120PBF is 2.5 V maximum at TJ = 25 °C and IS = 1.3 A with VGS = 0 V. This parameter is critical for freewheeling paths in low-frequency switching applications and affects conduction loss during reverse recovery.
Is IRLD120PBF compatible with lead-free soldering processes?
Yes, IRLD120PBF is marked "PbF" and qualified for lead-free soldering per J-STD-020. Its package withstands peak reflow temperatures up to 300 °C for 10 seconds, meeting standard Pb-free process requirements without degradation to electrical or mechanical performance.
