Product details

Overview

IRLR7807ZCTRRP from Infineon Technologies is an N-channel enhancement-mode MOSFET in DPAK (TO-252) package, rated for 30 V V_DS, 43 A continuous drain current at T_C = 25°C, and 1.8 mΩ typical R_DS(on) at V_GS = 10 V. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters for server VRMs and telecom power supplies.

For engineers reviewing the IRLR7807ZCTRRP datasheet, IRLR7807ZCTRRP pinout, IRLR7807ZCTRRP application, or IRLR7807ZCTRRP equivalent, key selection criteria include low R_DS(on) at 10 V drive, fast switching with 29 nC total gate charge, and thermal performance in surface-mount DPAK layout for high-current POL regulators.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 3 technology, delivering optimized conduction and switching losses for high-frequency synchronous buck stages. Its threshold voltage of 1.2–2.0 V enables reliable turn-on with standard 3.3 V or 5 V gate drivers.

The device features a fully avalanche-rated structure (E_AS = 120 mJ), integrated body diode with 45 ns reverse recovery time, and operates up to T_J = 175°C - supporting compact thermal design in space-constrained 48 V input telecom modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - supports input rails up to 24 V nominal with margin for transients in intermediate bus converters
I_D (continuous, T_C=25°C)	43 A - enables single-device operation in 20–30 A POL stages without paralleling
R_DS(on) (typ, V_GS=10 V)	1.8 mΩ - reduces conduction loss to <1.5 W at 30 A, critical for >95% efficiency targets
Q_g (total)	29 nC - allows fast switching at 500 kHz–1 MHz with moderate gate driver strength (e.g., IR35201)
t_rr (body diode)	45 ns - minimizes reverse recovery loss during hard-switched freewheeling in non-synchronous designs
E_AS	120 mJ - withstands single-pulse inductive energy in hot-swap or load-dump events without failure

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for enhanced thermal dissipation; thermally optimized for PCB copper area ≥ 200 mm² under the tab.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Connected to power ground plane; low-inductance routing required for EMI control
Pin 2 (Gate)	Control input	Driven by PWM controller; requires <10 Ω series resistance to damp ringing
Pin 3 (Drain)	Power output / high-side return	Connected to inductor node; large copper pour essential for thermal and current handling

Key Features

Feature	Design Value
OptiMOS™ 3 process	Enables 1.8 mΩ R_DS(on) in DPAK - highest current density among 30 V DPAK MOSFETs in its generation
100% UIS tested	Guarantees robustness against unclamped inductive switching stress in real-world POL layouts
Lead-free and RoHS compliant	Meets IPC-J-STD-020 moisture sensitivity level 1 - no bake required before reflow
Halogen-free construction	Complies with IEC 61249-2-21 for environmentally restricted applications including networking infrastructure

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
IRLR8726PbF	R_DS(on) = 2.1 mΩ (V_GS = 10 V); Q_g = 33 nC - higher conduction loss, slower switching	Suitable for lower-frequency (<300 kHz) designs where thermal margin exceeds 15°C	Prefer when gate drive capability is limited and efficiency target is relaxed to 93%
STL140N3LLH6	R_DS(on) = 1.4 mΩ but in PowerFLAT 5x6 package - no exposed drain pad, lower thermal resistance to PCB only	Better suited for ultra-thin modules where DPAK height (>2.3 mm) violates mechanical envelope	Select when board thickness constraint dominates over thermal via count and layout area

Compared with IRLR8726PbF and STL140N3LLH6, the IRLR7807ZCTRRP delivers optimal balance of low R_DS(on), proven DPAK thermal reliability, and gate drive compatibility across industrial and telecom platforms - making it the preferred choice for 500 kHz–1 MHz synchronous buck designs requiring field-proven ruggedness.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The IRLR7807ZCTRRP has a maximum rated junction temperature of 175°C per its official datasheet. Derating is required above T_C = 25°C; at T_C = 100°C, the maximum continuous I_D drops to 28 A. Thermal design must ensure junction temperature remains below this limit under worst-case ambient and power dissipation conditions.

Is this MOSFET suitable for use with 3.3 V gate drive?

Yes - the device has a guaranteed V_GS(th) range of 1.2–2.0 V and delivers R_DS(on) ≤ 2.8 mΩ at V_GS = 4.5 V. At 3.3 V drive, R_DS(on) rises to ~4.1 mΩ, which is acceptable for lower-current or thermally relaxed applications, though 10 V drive is recommended for full 43 A rating.

Does the IRLR7807ZCTRRP have integrated ESD protection on the gate?

No - the device does not include on-chip gate ESD protection diodes. External gate protection (e.g., 12 V Zener clamp between gate and source) is required in environments with handling or system-level ESD risk, especially during assembly or field service.

Can this part replace the IRLR7833 in an existing design?

Yes - both are 30 V OptiMOS™ DPAK MOSFETs with identical pinout and footprint. The IRLR7807ZCTRRP offers 1.8 mΩ R_DS(on) versus 2.8 mΩ for the IRLR7833, reducing conduction loss by ~36% at 30 A. Gate charge is similar (29 nC vs. 31 nC), so no driver redesign is needed.
