Product details
Overview
IRF9630 from Vishay Siliconix is a P-channel enhancement-mode power MOSFET designed for high-voltage switching in industrial and power conversion circuits. It features -200 V drain-source voltage rating, 0.80 Ω maximum RDS(on) at VGS = -10 V, 29 nC total gate charge, and TO-220AB package - enabling robust operation in DC-DC converters, motor controls, and relay replacement applications.
For engineers reviewing the IRF9630 datasheet, IRF9630 pinout, IRF9630 application, or IRF9630 equivalent, this page delivers verified electrical parameters, thermal performance data, body diode recovery characteristics, avalanche energy ratings, and real-world design context for high-reliability P-channel switching at up to -200 V.
Technical Context
The IRF9630 operates as a voltage-controlled unidirectional switch with gate threshold voltage between -2.0 V and -4.0 V, requiring negative gate drive relative to source. Its -200 V VDS rating and -6.5 A continuous drain current (TC = 25 °C) support high-side switching in off-line SMPS and battery-powered systems where polarity inversion is required.
It integrates a fast-recovery body diode with 200–300 ns reverse recovery time and 1.9–2.9 μC Qrr, and is rated for repetitive avalanche energy (7.4 mJ) and single-pulse avalanche (500 mJ), enabling rugged operation under inductive load switching without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -200 V - supports high-side switching in 170 V AC rectified rails and industrial 200 V DC bus systems |
| RDS(on) max | 0.80 Ω @ VGS = -10 V - enables <1.5 W conduction loss at -6.5 A, suitable for medium-power switching |
| Qg | 29 nC - determines gate driver strength requirement; compatible with standard logic-level drivers at ≤100 kHz |
| ID cont. | -6.5 A @ TC = 25 °C - defines thermal design basis using TO-220AB's 1.7 °C/W RthJC |
| EAS | 500 mJ - allows safe unclamped inductive turn-off in motor drives and solenoid control without snubber |
| dV/dt rating | -5.0 V/ns - ensures immunity to parasitic turn-on in high-dI/dt environments like half-bridge configurations |
| TJ range | -55 to +150 °C - supports extended temperature operation in automotive under-hood and industrial enclosures |
Pinout & Package
IRF9630 is housed in a TO-220AB package with standard three-terminal layout: Drain (D) connected to tab, Source (S) at lead 1, Gate (G) at lead 2 - enabling direct heatsink mounting and simplified PCB layout for high-current paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (left, viewing front) | Source (S) | Main current return path; tied to system ground or low-side reference in high-side switch configuration |
| Lead 2 (center) | Gate (G) | Control input requiring -10 V for full enhancement; isolated from power path by internal oxide dielectric |
| Tab / Lead 3 (right) | Drain (D) | High-voltage output node; electrically connected to metal tab - must be insulated from heatsink unless referenced to same potential |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Supports ≥6.4 A repetitive avalanche current - eliminates need for external clamping in flyback and forward converter primary switches |
| Dynamic dV/dt rating | -5.0 V/ns immunity - prevents false triggering during fast voltage transients in bridge-leg commutation |
| Fast switching | 27 ns rise time and 24 ns fall time - enables efficient operation up to 200 kHz in hard-switched topologies |
| Low gate charge | 29 nC total charge - reduces driver power dissipation and simplifies gate drive circuitry versus higher-Q alternatives |
| TO-220AB thermal performance | 1.7 °C/W RthJC - delivers 74 W power dissipation capability with minimal heatsink volume in convection-cooled designs |

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 |
|---|---|---|---|
| IRF9530PbF | VDS = -100 V, RDS(on) = 0.30 Ω @ -10 V - lower voltage rating but lower on-resistance | Not suitable for 200 V bus applications; limited to ≤100 V DC systems | Select only when operating voltage remains below 80 V and lower conduction loss is prioritized over voltage margin |
| STP12PF06 | VDS = -60 V, RDS(on) = 0.27 Ω @ -10 V, Qg = 22 nC - optimized for lower voltage, higher frequency use | Lacks avalanche rating and 200 V capability; unsuitable for off-line or industrial HV rails | Prefer for 24–48 V automotive or telecom systems where fast switching and low Qg outweigh voltage headroom needs |
Compared with IRF9530PbF and STP12PF06, the IRF9630 uniquely delivers -200 V blocking with verified repetitive avalanche capability - making it the only viable choice among the three for 170 V AC-derived supplies, industrial 200 V DC buses, and high-energy inductive load switching where voltage margin and ruggedness are non-negotiable.

FAQ
What is the maximum continuous drain current for IRF9630 at 100 °C case temperature?
The IRF9630 supports -4.0 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220AB package and must be used in thermal design calculations alongside RthJC = 1.7 °C/W to ensure junction temperature remains ≤150 °C. The IRF9630 datasheet confirms this value under standardized test conditions with proper heatsinking.
Does IRF9630 have a fully rated avalanche capability, and what does that mean for circuit design?
Yes, the IRF9630 is explicitly rated for repetitive avalanche with IAR = -6.4 A and EAR = 7.4 mJ, and single-pulse avalanche energy of 500 mJ. This means the IRF9630 can safely absorb inductive energy during unclamped turn-off events - such as in relay driving or motor freewheeling - without requiring external clamping components. Designers may rely on this rating to simplify protection circuitry while maintaining reliability in the IRF9630-based system.
What is the gate threshold voltage range for IRF9630, and how does it affect drive requirements?
The IRF9630 has a gate threshold voltage range of -2.0 V to -4.0 V, measured at VDS = VGS and ID = -250 μA. This relatively wide range means gate drive must provide at least -10 V to ensure full enhancement and low RDS(on). Logic-level drivers are insufficient; dedicated negative-bias gate drivers or level-shifted circuits are required to reliably operate the IRF9630 across temperature and process variation.
Can IRF9630 be used in parallel configurations, and what design considerations apply?
Yes, the IRF9630 is designed for ease of paralleling, as confirmed in its Features list. Key considerations include matched gate resistors (≤2 Ω per device), symmetrical PCB layout to minimize loop inductance, and thermal coupling via shared heatsink to ensure current sharing. The positive RDS(on) temperature coefficient promotes inherent current balancing above 25 °C - a critical advantage validated in the IRF9630's transfer characteristics and thermal resistance data.
Is IRF9630 RoHS-compliant, and which variant meets this requirement?
Yes, the IRF9630PbF variant is RoHS-compliant and lead (Pb)-free, as documented in the Ordering Information section of the Vishay datasheet (Document Number: 91084). The standard IRF9630 part uses SnPb terminations and is not RoHS-compliant. For new designs requiring environmental compliance, IRF9630PbF must be specified - and its packaging, marking, and soldering profile (peak 300 °C for 10 s) are fully aligned with RoHS Directive 2011/65/EU.
