Product details
Overview
IRFB9N30APBF from Vishay Siliconix is a 300 V, 9.3 A N-channel enhancement-mode power MOSFET in TO-220 package, featuring 0.45 Ω RDS(on) at VGS = 10 V, 33 nC total gate charge, and repetitive avalanche rating-designed for hard-switched SMPS, motor drives, and DC-DC converters requiring ruggedness and fast switching.
For engineers reviewing the IRFB9N30APBF datasheet, IRFB9N30APBF pinout, IRFB9N30APBF application, or IRFB9N30APBF equivalent, key selection criteria include its 160 mJ single-pulse avalanche energy, 4.6 V/ns peak diode recovery dV/dt capability, TO-220 thermal resistance (RthJC = 1.3 °C/W), and RoHS-compliant lead-free termination.
Technical Context
This third-generation TrenchFET® MOSFET employs optimized cell layout and process to achieve low Qgd/Qg ratio (12/33 nC), supporting high-efficiency hard-switching operation. Its body diode exhibits 280–420 ns reverse recovery time (trr) and 1.5–2.3 µC Qrr under standardized 100 A/µs di/dt conditions.
The device is rated for continuous drain current up to 9.3 A at TC = 25 °C and derates linearly at 0.77 W/°C above 25 °C case temperature. It supports unclamped inductive switching with IAR = 9.3 A and EAR = 9.6 mJ under repetitive avalanche conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 300 V - Maximum blocking voltage before avalanche onset; enables use in 240 V AC rectified bus applications. |
| RDS(on) | 0.45 Ω @ VGS = 10 V - Determines conduction loss at 5.6 A ID; yields ~14.2 W max I²R loss at full rated current. |
| Qg | 33 nC - Total gate charge required for full turn-on; defines driver strength requirement and switching loss trade-off. |
| EAS | 160 mJ - Single-pulse avalanche energy handling capacity; critical for inductive load switching reliability. |
| RthJC | 1.3 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting with predictable thermal rise. |
| trr | 280–420 ns - Body diode reverse recovery time; impacts commutation losses and EMI in freewheeling paths. |
| VGS(th) | 2.0–4.0 V - Gate threshold voltage range; ensures reliable turn-on with standard 10 V gate drivers while avoiding false triggering. |
Pinout & Package
IRFB9N30APBF is housed in a through-hole TO-220AB package with isolated tab (drain-connected). The package features low thermal resistance (RthJC = 1.3 °C/W), 10 lbf·in mounting torque rating, and RoHS-compliant matte tin (Sn) lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current-carrying terminal connected to MOSFET die substrate | Electrically and thermally coupled to metal tab; requires insulating washer if mounted to grounded heatsink. |
| Gate | Control electrode modulating channel conductivity | High-impedance input (IGSS ≤ ±100 nA); driven by 10 V logic-level signal for full enhancement. |
| Source | Reference node for gate drive and current return path | Common connection point for source resistor sensing and gate driver return; internal inductance LS = 7.5 nH affects switching waveform fidelity. |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Supports 9.3 A IAR and 9.6 mJ EAR without degradation-enables robust operation in inductive switching circuits without snubbers. |
| Dynamic dv/dt rated | 4.6 V/ns peak diode recovery dV/dt tolerance-reduces risk of spurious turn-on during high-speed commutation. |
| Low Qgd/Qg ratio | 12/33 nC (36%)-improves Miller immunity and enables faster, more controllable turn-off in hard-switched topologies. |
| Fast switching performance | td(on) = 10 ns, tr = 25 ns, td(off) = 35 ns, tf = 29 ns @ VDD = 150 V, ID = 9.3 A-minimizes transition losses in high-frequency SMPS. |
| Lead (Pb)-free construction | RoHS-compliant matte tin plating on leads and tab-meets environmental compliance requirements without sacrificing solderability or thermal performance. |

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 |
|---|---|---|---|
| STP9NK30ZFP | 300 V, 9 A, RDS(on) = 0.45 Ω, but uses SuperMESH™ Zener-protected gate; Qg = 32 nC, trr = 350 ns. | Higher gate robustness against overvoltage; slightly slower body diode recovery than IRFB9N30APBF. | Preferred where gate transient immunity is prioritized over minimal trr. |
| IXTP9N30P | 300 V, 9 A, RDS(on) = 0.45 Ω, but TO-220FP (full-pack) variant; Qg = 30 nC, trr = 320 ns, RthJC = 1.5 °C/W. | Same electrical specs but higher thermal resistance; non-isolated tab requires insulated mounting. | Acceptable when isolation is not required and board space allows full-pack footprint. |
Compared with STP9NK30ZFP and IXTP9N30P, IRFB9N30APBF offers superior thermal performance (RthJC = 1.3 °C/W), tighter trr distribution (280–420 ns), and industry-standard isolated-tab TO-220AB mechanical compatibility-making it optimal for thermally constrained, high-reliability industrial power stages.

FAQ
What is the maximum continuous drain current rating for IRFB9N30APBF at 100 °C case temperature?
The IRFB9N30APBF has a continuous drain current rating of 5.9 A at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220 package and must be applied in thermal design calculations alongside RthJC = 1.3 °C/W and ambient conditions. The IRFB9N30APBF maintains safe operation only within this current limit at elevated case temperatures.
Does IRFB9N30APBF have a built-in gate protection diode?
No, the IRFB9N30APBF does not integrate a gate protection Zener diode. Its gate-source voltage rating is ±30 V, and gate-source leakage is specified at ±100 nA at ±30 V. External gate protection (e.g., 15 V Zener clamp) is recommended in noisy or high-dV/dt environments. This differs from alternatives like STP9NK30ZFP, which includes integrated gate Zener protection.
What is the typical body diode forward voltage of IRFB9N30APBF at 9.3 A and 25 °C junction temperature?
The typical body diode forward voltage (VSD) of IRFB9N30APBF is 1.5 V at IS = 9.3 A and TJ = 25 °C with VGS = 0 V, per the "Drain-Source Body Diode Characteristics" section. This value increases with temperature and current-designers should reference Fig. 7 in the datasheet for full VSD vs. ISD curves across operating conditions.
Can IRFB9N30APBF be paralleled with identical units for higher current handling?
Yes, IRFB9N30APBF is explicitly designed for ease of paralleling, as noted in its FEATURES list. Its positive RDS(on) temperature coefficient (shown in Fig. 4) promotes current sharing between paralleled devices. Successful implementation requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling-verified in Vishay's application notes for multi-MOSFET configurations.
Is IRFB9N30APBF suitable for use in automotive applications?
The IRFB9N30APBF is not AEC-Q101 qualified and is intended for commercial and industrial applications only. While its absolute maximum ratings (e.g., TJ = –55 to +150 °C) meet some automotive temperature ranges, Vishay does not certify or characterize IRFB9N30APBF for automotive use. For automotive-grade equivalents, consult Vishay's AEC-Q101-qualified power MOSFET portfolio.
