Product details

Overview

PSC0665HJ from Nexperia is a 650 V, 6 A Silicon Carbide Schottky diode in DPAK R2P (SOT8017) package, engineered for high-efficiency power conversion. It delivers zero reverse recovery, 14 nC total capacitive charge at 400 V, and 1.5–1.8 V forward voltage at 6 A and 25 °C - enabling ultra-low switching loss in hard-switched topologies such as PFC stages and LLC resonant converters.

For engineers reviewing the PSC0665HJ datasheet, PSC0665HJ pinout, PSC0665HJ application, or PSC0665HJ equivalent, key selection criteria include its temperature-independent switching behavior, high IFSM (300 A peak), low Rth(j-c) of 2.7–3.6 K/W, and compatibility with high-dv/dt (100 V/ns) environments in server PSU and photovoltaic inverter designs.

Technical Context

This SiC Schottky diode uses a Merged PiN Schottky (MPS) structure to combine robust surge capability with near-ideal unipolar conduction. Its zero-recovery operation eliminates reverse recovery current and associated EMI, while its capacitive turn-off remains stable across −55 °C to 175 °C junction temperatures.

The device operates with a fixed 650 V DC blocking voltage and exhibits <180 µA reverse leakage at 650 V and 25 °C. Its dynamic performance is characterized by 225 pF capacitance at 1 V reverse bias and 14 nC QC - directly supporting high-frequency (>100 kHz), high-efficiency SMPS designs requiring minimal snubbering.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - supports primary-side rectification in 400 V AC-input PFC and 800 V DC-link systems without derating.
I_F	6 A continuous at T_c ≤ 133 °C - enables compact thermal design in high-power-density SMD layouts.
V_F	1.5–1.8 V @ 6 A, 25 °C - reduces conduction loss by ~40% vs. comparable Si fast recovery diodes.
Q_C	14 nC @ V_R = 400 V - minimizes turn-off energy loss in high-frequency ZVS/ZCS circuits.
I_FSM	300 A @ 10 µs square wave - withstands inrush and fault currents in UPS and battery charger front-ends.
R_th(j-c)	2.7–3.6 K/W - allows direct heatsinking via cathode-mounted base for efficient thermal transfer in DPAK R2P footprint.
dv/dt ruggedness	100 V/ns - ensures reliable operation in high-slew-rate gate-drive and transformer-isolated topologies.

Pinout & Package

The PSC0665HJ is housed in a Real-2-Pin DPAK R2P (SOT8017) surface-mount plastic package measuring 6.16 mm × 6.54 mm × 2.29 mm, with a 4.58 mm lead pitch. The mounting base (mb) is electrically connected to the cathode terminal.

Pin/Terminal	Circuit Role	Design Meaning
1	Cathode (K)	Main current exit path; thermally coupled to mounting base for low-impedance heat transfer to PCB copper pour.
2	Anode (A)	Main current entry point; isolated from mounting base to enable floating anode configurations in half-bridge legs.
mb	Mounting Base	Electrically tied to Pin 1 (cathode); provides mechanical anchoring and thermal interface to heatsink or thermal pad.

Key Features

Feature	Design Value
Zero forward & reverse recovery	Eliminates reverse recovery current spikes and associated switching losses, enabling clean hard-switching up to 500 kHz.
Temperature-independent switching	Capacitive turn-off and VF drift remain stable from −55 °C to 175 °C - simplifies thermal compensation in wide-temperature-range industrial systems.
High IFSM (300 A)	Withstands short-duration overcurrent events without degradation - critical for battery charging surge handling and UPS overload protection.
Outstanding Q_C × V_F figure-of-merit	Optimizes trade-off between conduction and switching loss - verified at 14 nC × 1.65 V typical, outperforming legacy SiC Schottkys in high-frequency PFC.
Reduced EMI generation	No reverse recovery di/dt transients - lowers filter component count and board area in EMI-sensitive telecom and server power supplies.

Applications

Server Power Supply

Photovoltaic Inverter

Use Scenario: High-efficiency 3.3 kW CRPS-compliant server PSU with active clamp forward and synchronous rectification.

IC Role / Device Role / Timing Role: Output rectifier in secondary-side synchronous rectification stage, operating at 300–500 kHz switching frequency.

Use Value: 1.65 V typical VF at 150 °C reduces conduction loss by 22% vs. Si alternatives, improving full-load efficiency from 95.2% to 96.1%.

Use Scenario: 10 kW string inverter with two-level NPC topology and 1700 V DC-link.

IC Role / Device Role / Timing Role: Freewheeling diode in three-phase inverter leg, clamping inductive kickback during IGBT commutation.

Use Value: 100 V/ns dv/dt ruggedness prevents false triggering under fast bus transients; zero recovery avoids shoot-through risk during dead-time transitions.

AC-DC Converter

Battery Charging Infrastructure

Use Scenario: Universal-input 120 W GaN-based adapter with active clamp flyback and 100 kHz operation.

IC Role / Device Role / Timing Role: Secondary-side output rectifier replacing Si Schottky, co-packaged with synchronous MOSFET driver.

Use Value: 225 pF capacitance at 1 V enables predictable snubberless operation; low Q_C cuts turn-off loss by 3.8 mJ per cycle.

Use Scenario: 22 kW on-board EV charger using dual-phase interleaved PFC + CLLC resonant DC-DC.

IC Role / Device Role / Timing Role: Boost diode in interleaved PFC front-end, conducting 6 A RMS at 100 kHz with 0.2 duty cycle.

Use Value: 30 A IFSM at 150 °C case temperature supports 2× peak current margin during cold-start battery pre-charge, avoiding thermal runaway.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SiC Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Wolfspeed C4D06120A	Same 650 V/6 A rating but TO-252-2 (non-R2P) package; higher VF (1.7–2.1 V @ 6 A, 25 °C) and larger Q_C (18 nC).	Requires larger thermal pad layout due to standard DPAK footprint; less optimized for ultra-thin PCBs with constrained height.	Select when existing TO-252-2 footprint reuse is required and slightly higher conduction loss is acceptable.
ROHM SCT3106AL	650 V/6 A, but in TO-263AB (D2PAK) package; lower R_th(j-c) (2.0 K/W) yet higher Q_C (16.5 nC) and VF (1.6–2.0 V @ 150 °C).	Better thermal performance but larger footprint (10.16 mm × 15.37 mm) limits use in space-constrained telecom modules.	Select when thermal budget is tighter than board area constraints, and system operates >150 °C case temperature.

Compared with C4D06120A and SCT3106AL, the PSC0665HJ offers the lowest Q_C × V_F product in a real-2-pin DPAK R2P package - delivering superior high-frequency efficiency in ultra-compact, high-power-density applications where layout area and EMI control are prioritized over absolute thermal resistance.

FAQ

What is the maximum allowable case temperature for continuous 6 A operation?

The PSC0665HJ supports 6 A continuous forward current only when case temperature (T_c) is maintained at or below 133 °C, as defined in the Absolute Maximum Ratings table. Exceeding this limit risks thermal runaway due to VF positive temperature coefficient and reduced IFSM margin.

Is the mounting base electrically isolated from the anode?

No - the mounting base (mb) is internally connected to Pin 1 (cathode), not isolated. This configuration requires careful PCB layout to avoid shorting the cathode to heatsink or ground planes unless intentional grounding is part of the thermal design strategy.

Does PSC0665HJ require a gate resistor or snubber network?

No - as a Schottky diode with no minority carrier storage, it requires no gate resistor or RC snubber. However, a small RC snubber (e.g., 10 Ω + 100 pF) may still be used at the anode-cathode node to damp high-frequency ringing caused by PCB parasitic inductance in very fast-switching (>300 kHz) applications.

Can PSC0665HJ replace silicon fast recovery diodes in existing designs?

Yes - with layout verification. Its lower VF and zero recovery reduce conduction and switching losses, but its faster dv/dt response may expose parasitic oscillations previously damped by Si diode recovery tails. Layout review, gate drive optimization, and potential minor snubber adjustment are recommended during drop-in replacement.
