Product details
Overview
IRF9620L from Vishay Siliconix is a P-channel enhancement-mode power MOSFET designed for high-voltage switching in DC-DC converters, motor control, and load switching applications. It features -200 V drain-source voltage rating, 1.5 Ω RDS(on) at VGS = -10 V, 22 nC total gate charge, TO-220AB package, and -3.5 A continuous drain current at TC = 25 °C.
For engineers reviewing the IRF9620L datasheet, IRF9620L pinout, IRF9620L application, or IRF9620L equivalent, this device is selected for medium-power, high-side switching where rugged dV/dt immunity (-5.0 V/ns), fast turn-on/turn-off (td(on) = 15 ns, tf = 15 ns), and ease of paralleling are critical design requirements.
Technical Context
The IRF9620L operates as a voltage-controlled unidirectional switch with gate-driven channel inversion in a vertical DMOS structure. Its -200 V VDS rating and -4.0 V maximum VGS(th) enable reliable operation in high-side configurations up to 160 V bus systems, while its 3.1 °C/W RthJC supports thermal management in convection-cooled industrial enclosures.
Dynamic performance is defined by low Crss (30 pF) and Qgd/Qg ratio (~45%), contributing to stable switching under high dV/dt stress. The integral body diode exhibits 300–450 ns reverse recovery time and 1.9–2.9 μC Qrr, making it suitable for non-synchronous flyback and clamped inductive loads without external snubbing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -200 V - Supports 160 V nominal bus designs with 25% safety margin against transients |
| RDS(on) | 1.5 Ω @ VGS = -10 V - Delivers ≤5.3 W conduction loss at -3.5 A, enabling TO-220AB use without forced air |
| Qg | 22 nC - Enables efficient gate drive with standard ±12 V logic-level drivers (e.g., TC4427) |
| dV/dt Rating | -5.0 V/ns - Immune to false triggering in noisy industrial environments with fast-rising edge noise |
| ID Continuous | -3.5 A @ TC = 25 °C - Sustains 40 W power dissipation with standard heatsink mounting (RthCS = 0.50 °C/W) |
| Body Diode VSD | -7.0 V @ IS = -3.5 A - Limits forward conduction loss during freewheeling in half-bridge topologies |
Pinout & Package
IRF9620L uses the industry-standard TO-220AB package with isolated tab (drain-connected), 3-pin through-hole configuration. Mounting requires M3 screw and 1.1 N·m torque; soldering peak temperature must not exceed 300 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / heat sink interface | Electrically connected to metal tab; must be electrically isolated from chassis unless system ground reference permits |
| Gate | Voltage-controlled switch input | High-impedance node requiring <100 nA leakage control; sensitive to ESD-requires series gate resistor (≥10 Ω) and TVS protection |
| Source | Reference node for gate drive and load return | Common connection point for load, gate driver return, and current sensing; defines local ground potential in high-side layout |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic dV/dt rating | -5.0 V/ns immunity enables robust operation in high-noise motor drives and SMPS without false turn-on |
| Fast switching | 15 ns turn-on delay + 15 ns fall time allows >1 MHz hard-switching in low-duty-cycle applications |
| Ease of paralleling | Positive RDS(on) temperature coefficient ensures current sharing stability across multiple IRF9620L devices |
| Simple drive requirements | ±20 V VGS rating and 22 nC Qg allow direct interfacing with microcontroller GPIO via single-stage buffer |
Applications
| Industrial Motor Control | DC-DC Converter High-Side Switch |
|---|---|
Use Scenario: Controlling bidirectional 24–48 V brushed DC motors in programmable logic controller (PLC) I/O modules. IC Role / Device Role / Timing Role: High-side P-channel switch enabling PWM-based speed regulation and dynamic braking via source-follower gate drive. Use Value: -200 V VDS withstands inductive kickback spikes up to 120 V; RDS(on) = 1.5 Ω limits I²R loss to <18 W at 3.5 A peak. |
Use Scenario: Non-synchronous buck converter for 12 V → 5 V conversion in industrial sensor nodes. IC Role / Device Role / Timing Role: Upper switch in step-down topology operating at 200 kHz with 30% duty cycle. Use Value: Low Qgd/Qg ratio minimizes Miller-induced shoot-through risk; body diode trr = 300–450 ns avoids excessive ringing during freewheeling. |
| Load Switch for 24 V Systems | Overvoltage Protection Circuit |
Use Scenario: Hot-swap power sequencing in DIN-rail mounted programmable automation controllers (PACs). IC Role / Device Role / Timing Role: Controlled power rail enable switch with soft-start via RC gate ramp. Use Value: Gate threshold VGS(th) = -2.0 to -4.0 V ensures clean turn-on at -10 V drive; low IDSS (<100 μA) prevents standby leakage in always-on systems. |
Use Scenario: Crowbar-style overvoltage clamp protecting downstream 12 V logic from 24 V supply faults. IC Role / Device Role / Timing Role: Voltage-triggered shunt switch activated by comparator-driven gate pull-down. Use Value: -5.0 V/ns dV/dt rating prevents spurious triggering during transient surges; ruggedized SOA supports single-pulse energy absorption up to 120 mJ. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF9540N | VDS = -100 V, RDS(on) = 0.2 Ω @ -10 V, Qg = 85 nC - lower voltage, lower RDS(on), higher gate charge | Not suitable for >100 V bus systems; better for high-current, low-voltage load switches | Select IRF9540N only when Vbus ≤ 80 V and conduction loss dominates over switching loss. |
| STP9NK90ZFP | VDS = -900 V, RDS(on) = 1.3 Ω @ -10 V, Qg = 42 nC - higher voltage, similar RDS(on), higher Qg | Designed for ZVS resonant converters; slower switching due to higher capacitance | Choose STP9NK90ZFP only for >400 V applications where avalanche ruggedness and high-voltage SOA are mandatory. |
Compared with IRF9620L, IRF9540N offers lower conduction loss but insufficient voltage margin for 160 V systems, while STP9NK90ZFP provides superior voltage rating but sacrifices switching speed and gate drive efficiency-making IRF9620L the optimal balance for 100–160 V industrial switching.

FAQ
What is the maximum continuous drain current for IRF9620L at 100 °C case temperature?
The IRF9620L supports -2.0 A continuous drain current at TC = 100 °C, derated linearly from -3.5 A at 25 °C using the 0.32 W/°C linear derating factor. This reflects thermal limitations of the TO-220AB package rather than silicon capability, and actual current handling depends on heatsink efficiency and ambient airflow. IRF9620L maintains safe operation within its SOA curve up to this limit.
Does IRF9620L have avalanche rating, and what is its rated repetitive avalanche energy?
The IRF9620L datasheet does not specify a rated repetitive avalanche energy (EAS) or single-pulse avalanche capability. While the device exhibits inherent avalanche robustness due to its planar DMOS structure, Vishay does not guarantee or characterize avalanche operation for IRF9620L. Designers must avoid operation beyond the SOA boundary shown in Figure 4 and implement external clamping if inductive energy dissipation is required. IRF9620L is not intended for unclamped inductive switching.
Can IRF9620L be used with logic-level gate drive (e.g., 3.3 V or 5 V microcontroller outputs)?
No-IRF9620L requires VGS ≤ -10 V for full enhancement and specified RDS(on) = 1.5 Ω. Its gate threshold range is -2.0 V to -4.0 V, meaning 5 V logic cannot reliably turn it fully on; at VGS = -5 V, RDS(on) rises significantly (>3 Ω), increasing conduction loss and thermal stress. IRF9620L must be driven with ≥-10 V gate voltage via level-shifting or dedicated high-side driver. IRF9620L is not a logic-level MOSFET.
What is the thermal resistance from junction to case (RthJC) for IRF9620L, and how does it impact heatsink selection?
The IRF9620L has a maximum junction-to-case thermal resistance (RthJC) of 3.1 °C/W, measured from die to TO-220AB drain tab. This value enables precise heatsink sizing: for example, to maintain TJ ≤ 125 °C at 40 W dissipation and 25 °C ambient, the required total RthSA (sink-to-ambient) is ≤ (125 − 25)/40 − 3.1 = 1.65 °C/W. IRF9620L's low RthJC makes it compatible with compact extruded aluminum heatsinks in convection-only environments.
Is IRF9620L RoHS-compliant, and what are its lead-free ordering options?
Yes-IRF9620L is available in RoHS-compliant, lead (Pb)-free versions. The standard lead-free variant is IRF9620PbF; the halogen-free version is IRF9620PbF-BE3. Both retain identical electrical and thermal specifications as the legacy Pb-bearing part. Vishay confirms material compliance per document 99912, and IRF9620L meets JEDEC J-STD-609A Class 1 marking requirements for lead-free identification.
