Product details
Overview
NRVUD620CTT4G from onsemi is an ultrafast dual common-cathode rectifier in DPAK package, rated for 200 V peak reverse voltage and 6.0 A average forward current per device (3.0 A per diode), with 35 ns reverse recovery time at IF = 1 A. It serves as a switching-mode power rectifier in DC-DC converters and as a freewheeling diode in automotive power supplies.
For engineers reviewing the NRVUD620CTT4G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, Pb-free RoHS-compliant DPAK-3 package, 9 °C/W junction-to-case thermal resistance, and low 1.13 V forward voltage at 6 A/25 °C.
Technical Context
This device integrates two ultrafast silicon rectifiers in a single DPAK-3 surface-mount package with common cathode configuration. Its 35 ns trr enables high-frequency operation in SMPS topologies up to several hundred kHz, while the 200 V VRRM rating supports 12 V–48 V input bus applications with margin.
The dual-diode structure shares a common cathode terminal (Pin 3), with independent anodes on Pins 1 and 4 - enabling synchronous rectification or dual-output flyback configurations. Thermal performance is defined by RJC = 9 °C/W, requiring PCB copper area per onsemi's recommended minimum pad layout for 140 °C case temperature derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 200 V - supports 12–48 V automotive and industrial DC bus designs with 2× safety margin |
| Avg. Forward Current (Per Device) | 6.0 A at TC = 140 °C - enables compact 50–100 W power stage without forced air cooling |
| Reverse Recovery Time | 35 ns at IF = 1 A - minimizes switching loss in 200–500 kHz SMPS and reduces EMI generation |
| Forward Voltage | 1.13 V at IF = 6 A, TC = 25 °C - lowers conduction loss vs. standard FRDs, improving efficiency in high-current paths |
| Junction-to-Case Thermal Resistance | 9 °C/W - allows direct thermal coupling to heatsink or large copper pour for reliable 175 °C operation |
| ESD Rating (HBM) | Class 3B (> 8 kV) - ensures robustness during automated assembly and handling in automotive production lines |
| AEC-Q101 Qualified | Yes - certified for automotive under-hood and powertrain applications per stress test requirements |
Pinout & Package
DPAK-3 (Case 369C) surface-mount package: 6.10 mm × 6.54 mm × 2.28 mm body, 2.29 mm lead pitch, Pb-free matte tin plating, solderable at 260 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input path for first rectifier leg; connects to transformer secondary or switch node |
| Pin 2 | Cathode (Common) | Shared output node for both diodes; must be routed to low-inductance ground/power plane |
| Pin 3 | Thermal Pad / Cathode Tie | Electrically tied to Pin 2; provides primary thermal path to PCB copper; requires solder mask defined pad |
| Pin 4 | Anode of Diode 2 | Independent input path for second rectifier leg; enables dual-output or interleaved topology use |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (35 ns) | Reduces turn-off switching loss and associated heat generation in high-frequency converters |
| Common-cathode dual-diode architecture | Enables space-efficient dual-output rectification or phase-interleaved designs without discrete pairing |
| AEC-Q101 qualification | Validated for automotive power modules, engine control units, and ADAS power supplies |
| Pb-free, Halogen-free, RoHS-compliant | Meets global environmental compliance mandates including EU RoHS and JIGS-001 |
| Low leakage (5 µA @ 25 °C) | Minimizes standby power loss in always-on systems such as vehicle infotainment and telematics |
Applications
| Automotive DC-DC Converters | Industrial SMPS Outputs |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MURD620CTT4G | Same die, non-automotive grade; no AEC-Q101 qualification; identical electrical specs and DPAK-3 package | Approved for industrial/commercial use only; not suitable for automotive PPAP submissions | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive traceability needs |
| SRVUD620CTT4G | Same die, optimized for high-reliability industrial sites; includes extended PPAP documentation but same VRRM/trr/VF | Targeted at medical and telecom power supplies requiring full change control history | Prefer when full lot traceability, extended reliability testing, and controlled manufacturing site are mandatory |

FAQ
Is NRVUD620CTT4G still in active production?
No - the NRVUD620CTT4G is officially marked as discontinued per onsemi's October 2025 datasheet revision. It is not recommended for new designs. However, Aetrix Electronics maintains legacy inventory and supports existing production runs with traceable, date-code-controlled stock and lifecycle coordination services for the NRVUD620CTT4G.
What is the pin configuration of NRVUD620CTT4G?
The NRVUD620CTT4G uses a DPAK-3 package with four terminals: Pin 1 is Anode 1, Pin 2 is Common Cathode, Pin 3 is thermal pad electrically tied to Pin 2, and Pin 4 is Anode 2. This common-cathode dual-diode layout is confirmed in onsemi's mechanical drawing CASE 369C and marking diagram Style 3.
Does NRVUD620CTT4G support automotive qualification requirements?
Yes - the NRVUD620CTT4G is explicitly AEC-Q101 qualified and PPAP capable, as stated in its datasheet features section. This certification covers temperature cycling, humidity testing, and mechanical stress validation required for under-hood and powertrain applications, distinguishing it from non-automotive variants like MURD620CTT4G.
How does the thermal performance of NRVUD620CTT4G compare to standard FRDs?
The NRVUD620CTT4G delivers RJC = 9 °C/W, significantly better than typical TO-220 or SMC-packaged FRDs (RJC ≈ 25–40 °C/W). This enables higher power density in DPAK footprint designs. When mounted on onsemi's recommended minimum copper pad, it sustains 6.0 A at TC = 140 °C - verified in the datasheet's derating curves for the NRVUD620CTT4G.
Can NRVUD620CTT4G replace MURD620CTT4G in an existing design?
Yes - the NRVUD620CTT4G is pin-, package-, and electrically identical to MURD620CTT4G, differing only in automotive qualification and traceability. No PCB or schematic changes are needed. However, NRVUD620CTT4G adds AEC-Q101 compliance and PPAP documentation, making it suitable for automotive release where MURD620CTT4G is not approved.
