Product details
Overview
NRVUD320VT4G from onsemi is an ultrafast surface-mount power rectifier in DPAK (TO-252) package, rated for 200 V peak repetitive reverse voltage and 3.0 A average forward current at TC = 158°C, with 35 ns reverse recovery time and 0.95 V forward voltage drop at 3 A/25°C - used as free-wheeling diode in automotive-grade switching power supplies and inverters.
For engineers reviewing the NRVUD320VT4G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q101 qualification, Pb-free RoHS compliance, thermal resistance (RJC = 6°C/W), low leakage (<5 µA @ 25°C), and DPAK-3 mechanical outline compatibility with high-power density PCB layouts.
Technical Context
This device belongs to onsemi's NRVUD series of automotive-qualified ultrafast rectifiers optimized for high-frequency switching topologies. Its 35 ns recovery time enables efficient operation in SMPS operating above 100 kHz, while the 6°C/W junction-to-case thermal resistance supports direct heatsinking via the exposed drain pad.
The DPAK-3 package integrates a cathode-anode-cathode terminal configuration (Style 8), enabling dual-kathode paralleling for enhanced current handling without external bus bars. It meets AEC-Q101 stress testing requirements including temperature cycling, HTRB, and ESD (HBM >8 kV, MM >400 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands peak reverse transients in 12–48 V automotive DC-DC converters without breakdown. |
| IF(AV) | 3.0 A at TC = 158°C - Supports continuous conduction mode operation in compact 25 W–50 W power stages. |
| trr | 35 ns - Minimizes switching losses and EMI generation in hard-switched flyback and forward converters. |
| VF | 0.95 V @ 3 A, 25°C - Reduces conduction loss by ~15% vs. standard FRD counterparts at light-to-moderate loads. |
| RJC | 6°C/W - Enables direct thermal coupling to copper pour or heatsink, limiting junction rise to ≤18°C at 3 A. |
| IR | 5 µA @ 25°C, rated VR - Ensures minimal standby leakage in battery-sensitive systems like ADAS ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MURD320T4G | Same die, identical electrical specs, but not AEC-Q101 qualified; marking prefix MURD instead of NRVUD. | Approved for industrial/commercial use only; excluded from automotive PPAP documentation packages. | Select when AEC-Q101 compliance is not required and cost sensitivity outweighs qualification traceability. |
| SURD8320T4G | Same DPAK-3 package and 200 V/3 A rating, but uses different die process yielding 25 ns trr (vs. 35 ns) and 0.85 V VF @ 3 A. | Better suited for >300 kHz designs where recovery loss dominates efficiency; slightly higher leakage (10 µA). | Prefer for high-frequency PFC stages or resonant LLC secondaries where <30 ns trr improves ZVS margin. |
Compared with NRVUD320VT4G, MURD320T4G offers identical performance without automotive qualification overhead, while SURD8320T4G trades lower VF and faster trr for reduced thermal margin and non-AEC-Q101 status - making NRVUD320VT4G optimal for production automotive systems requiring validated reliability.

FAQ
What is the AEC-Q101 qualification status of the NRVUD320VT4G?
The NRVUD320VT4G is fully AEC-Q101 qualified and PPAP capable, with test reports covering temperature cycling, high-temperature reverse bias (HTRB), and ESD (HBM >8 kV, MM >400 V). This qualification confirms its suitability for automotive power modules, including engine control units and ADAS domain controllers where reliability under thermal and vibration stress is critical. The NRVUD320VT4G carries explicit AEC-Q101 certification in onsemi's official documentation.
How does the dual-cathode configuration (Pins 2 and 4) of the NRVUD320VT4G improve performance?
The dual-cathode layout in the NRVUD320VT4G allows parallel current paths through Pins 2 and 4, reducing effective series resistance and distributing surge current during IFSM events. This configuration supports the rated 75 A non-repetitive surge current while minimizing localized heating and improving thermal uniformity across the DPAK-3 package. In practice, it enables higher peak power handling without board-level copper reinforcement - a key advantage over single-cathode alternatives like MURD320T4G.
Can the NRVUD320VT4G replace the MURD320T4G in existing designs?
Yes, the NRVUD320VT4G is a direct drop-in replacement for the MURD320T4G in terms of pinout, package, and electrical specifications - both use DPAK-3 (Case 369C), share identical VRRM, IF(AV), trr, and VF. However, the NRVUD320VT4G adds AEC-Q101 qualification and unique site/control change tracking (via NRVUD prefix), making it mandatory for new automotive designs. No PCB or layout changes are needed when upgrading from MURD320T4G to NRVUD320VT4G.
What is the maximum allowable case temperature for continuous operation of the NRVUD320VT4G?
The NRVUD320VT4G is rated for 3.0 A average forward current at TC = 158°C, as specified in the Absolute Maximum Ratings table. Operation beyond this temperature risks exceeding the 175°C maximum junction temperature, especially given its RJC = 6°C/W. For reliable long-term use, maintain TC ≤150°C with adequate copper pour and airflow; derating curves in Figure 4 confirm 2.5 A is sustainable at 165°C case temperature.
Is the NRVUD320VT4G compatible with lead-free reflow soldering processes?
Yes, the NRVUD320VT4G is Pb-free and RoHS compliant, with a maximum lead and mounting surface temperature rating of 260°C for 10 seconds - fully compatible with standard IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles. Its epoxy molding compound and solderable terminal finish meet industry requirements for void-free solder joints and intermetallic formation stability during repeated thermal cycling.
