Product details
Overview
IRFR9120TRLPBF from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, rated for -100 V drain-source voltage, 0.60 Ω RDS(on) at VGS = -10 V, and 5.6 A continuous drain current at TC = 25 °C. It features repetitive avalanche capability (EAS = 210 mJ), fast switching (tr = 29 ns), and integrated body diode with trr = 100–200 ns - used in DC-DC synchronous buck converters and high-side load switches.
For engineers reviewing the IRFR9120TRLPBF datasheet, IRFR9120TRLPBF pinout, IRFR9120TRLPBF application, or IRFR9120TRLPBF equivalent, this page delivers verified electrical parameters, thermal derating behavior, gate charge profile (Qg = 18 nC), avalanche energy limits, and PCB-mount power dissipation (2.5 W) - all confirmed from Vishay's official S26-0614-Rev. E specification.
Technical Context
This device employs third-generation trench-gate silicon technology optimized for ruggedized operation under unclamped inductive switching. Its -100 V VDS rating and -4.0 V maximum VGS(th) support reliable turn-on with standard logic-level gate drivers in high-side configurations.
Thermal design relies on low RthJC = 3.0 °C/W (junction-to-case) and RthJA = 50 °C/W (PCB mount), enabling stable operation up to TJ = 150 °C. The integral body diode supports bidirectional current flow with VSD = -6.3 V at IS = -5.6 A and controlled dV/dt recovery (-5.5 V/ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -100 V - Supports high-side switching in 48 V industrial bus and telecom power systems. |
| RDS(on) @ VGS = -10 V | 0.60 Ω - Limits conduction loss to ≤ 19 W at 6.8 A pulsed drain current. |
| Qg | 18 nC - Determines gate drive power requirement; compatible with 1–2 A peak gate drivers. |
| ID (continuous) | -5.6 A @ TC = 25 °C - Enables 2.5 W PCB-mount operation without heatsink in compact layouts. |
| EAS | 210 mJ - Withstands single-pulse inductive energy in motor control and solenoid drive circuits. |
| tr/tf | 29 ns / 25 ns - Enables >500 kHz switching in isolated DC-DC topologies with minimal overlap loss. |
| VGS(th) | -2.0 to -4.0 V - Ensures robust turn-off margin against noise in noisy automotive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFR9024TRLPBF | VDS = -60 V, RDS(on) = 0.27 Ω @ -10 V, Qg = 22 nC | Lower voltage rating limits use in 48 V+ systems; higher gate charge increases driver loss. | Select when lower conduction loss at ≤60 V is prioritized over avalanche robustness. |
| SiHFR9120TR-GE3 | Same VDS, RDS(on), Qg, and package; Pb-free/halogen-free construction per JEDEC J-STD-609A. | No functional difference; identical performance in all operating conditions. | Preferred for RoHS-compliant designs requiring documented halogen-free status. |
Compared with IRFR9120TRLPBF, IRFR9024TRLPBF trades avalanche margin for lower RDS(on) at reduced voltage, while SiHFR9120TR-GE3 offers identical electrical behavior with enhanced environmental compliance - making it a drop-in replacement where halogen-free certification is mandatory.

FAQ
What is the maximum junction temperature for IRFR9120TRLPBF?
The IRFR9120TRLPBF has an operating junction temperature range of -55 °C to +150 °C. This limit is enforced during repetitive avalanche operation and defines the upper boundary for thermal design - exceeding 150 °C risks permanent parametric shift or failure. Derating curves in Figure 8 confirm safe operation down to 0.33 W/°C above 25 °C case temperature.
Does IRFR9120TRLPBF support logic-level gate drive?
No, IRFR9120TRLPBF is not a logic-level MOSFET. Its gate threshold voltage ranges from -2.0 V to -4.0 V, and it is specified for RDS(on) at VGS = -10 V. For reliable enhancement, gate drive must deliver ≥ -10 V; -5 V drive yields significantly higher RDS(on) and increased conduction loss.
Can IRFR9120TRLPBF be used in parallel configurations?
Yes, IRFR9120TRLPBF supports paralleling due to its negative temperature coefficient of RDS(on) (shown in Figure 3). As junction temperature rises, on-resistance increases - promoting current sharing among paralleled devices without external balancing resistors.
What is the recommended PCB layout for thermal performance of IRFR9120TRLPBF?
Vishay recommends a minimum 0.420" × 0.224" (10.67 mm × 5.69 mm) copper pad for the drain tab per Application Note 826. Use multiple thermal vias (≥6× 0.3 mm diameter) under the tab connected to inner-layer ground planes to achieve RthJA ≈ 50 °C/W in PCB-mount configuration.
Is IRFR9120TRLPBF suitable for linear mode operation?
No, IRFR9120TRLPBF is not characterized or rated for linear (ohmic) mode operation. Its Safe Operating Area (SOA) curve (Figure 7) shows limited DC capability - only 0.2 A at VDS = -80 V - and pulse operation is constrained by junction temperature rise. Linear use risks thermal runaway.
