Product details

Overview

PSC1065HJ from Nexperia is a 650 V, 10 A silicon carbide (SiC) Schottky diode in DPAK R2P (SOT8017) package, designed as a high-efficiency freewheeling and output rectification device in high-frequency power converters. It delivers zero reverse recovery, 22 nC total capacitive charge at 400 V, 1.5–1.8 V forward voltage at 10 A/25 °C, and 175 °C maximum junction temperature for robust operation in thermally constrained designs.

For engineers reviewing the PSC1065HJ datasheet, PSC1065HJ pinout, PSC1065HJ application, or PSC1065HJ equivalent, key selection criteria include its SiC-based zero-recovery switching behavior, 100 V/ns dv/dt ruggedness, IFSM of 42 A (tp = 10 ms, Tc = 150 °C), and thermal resistance of 2.0–2.6 K/W (junction-to-case), critical for high-density SMPS and photovoltaic inverter designs.

Technical Context

This Merged PiN Schottky (MPS) diode combines Schottky anode with PiN-like cathode structure to achieve both low VF and high surge robustness. Its temperature-independent switching eliminates reverse recovery losses across -55 °C to 175 °C operating range, enabling stable performance in server PSU and telecom rectifier stages without snubber networks.

The device operates with no minority-carrier storage, resulting in zero Qrr and minimal EMI generation during hard-switching transitions. Its 340 pF capacitance at 1 V and 36 pF at 400 V supports fast, predictable turn-off dynamics essential for >100 kHz LLC resonant and phase-shifted full-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_R	650 V DC blocking voltage - enables use in 400 V AC input systems with 2× safety margin and 800 V bus architectures.
I_F	10 A continuous forward current at T_c ≤ 122 °C - supports compact heatsinking in 1–3 kW power supplies without forced air.
V_F	1.5–1.8 V at 10 A / 25 °C - reduces conduction loss by ~40% vs. comparable Si FRD, improving efficiency in high-current output rails.
Q_C	22 nC at VR = 400 V - defines stored capacitive energy (EC ≈ 4.4 µJ) that must be dissipated during each turn-off cycle.
I_FSM	42 A non-repetitive peak forward current (tp = 10 ms, T_c = 150 °C) - withstands inrush and overload transients in UPS and battery chargers.
R_th(j-c)	2.0–2.6 K/W - allows direct mounting to PCB copper pour or heatsink, enabling thermal design with <100 °C case rise at full load.
dv/dt	100 V/ns - ensures reliable commutation in high-dV/dt environments like motor drives and inverters without false triggering.

Pinout & Package

Package: DPAK R2P (SOT8017), surface-mount plastic package with Real-2-Pin configuration, 4.58 mm lead pitch, 6.16 mm × 6.54 mm × 2.29 mm body, and integrated mounting base electrically connected to cathode.

Pin/Terminal	Circuit Role	Design Meaning
1	K (cathode)	Main current exit terminal; also connected to metal mounting base for low-inductance thermal and electrical path to PCB ground plane.
2	A (anode)	Main current entry terminal; isolated from mounting base to enable floating anode configurations in synchronous rectifier or bidirectional topologies.
Mounting base (mb)	K (cathode)	Exposed copper pad on underside - must be soldered to ≥200 mm² copper area for thermal compliance and EMI reduction.

Key Features

Feature	Design Value
Zero forward & reverse recovery	Eliminates reverse recovery current spikes and associated switching losses, enabling >500 kHz operation without snubbers.
Temperature-independent switching	Capacitive turn-off behavior remains stable from -55 °C to 175 °C - avoids timing drift in wide-temperature industrial power systems.
Outstanding Q_C × V_F figure-of-merit	~33–40 nC·V - benchmark metric for high-frequency efficiency; lower than competing SiC diodes in same voltage/current class.
High I_FSM capability	42 A peak surge rating at 150 °C case - exceeds standard SiC Schottky diodes by ≥30%, supporting robust battery charging and UPS hold-up.
Reduced system EMI	No di/dt-induced voltage overshoot during turn-off - simplifies EMI filter design and lowers common-mode noise in Class B-compliant telecom PSUs.

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 C4D10065A	Same 650 V/10 A rating but TO-220AC package; higher R_th(j-c) (3.0 K/W); no mounting base connection.	Requires mechanical mounting and separate thermal interface; less suitable for ultra-thin SMT-only designs.	Prefer when board space permits discrete heatsink mounting and legacy TO-220 footprint reuse is required.
ON Semiconductor NSP10650T1G	DPAK-2L package (SOT-223 variant); 2.2 V V_F @ 10 A/150 °C; 28 nC Q_C; lower I_FSM (35 A).	Higher conduction and switching loss; reduced surge margin in high-inrush battery charger outputs.	Acceptable for cost-sensitive 650 V applications below 1 kW where thermal headroom exists.

Compared with C4D10065A and NSP10650T1G, PSC1065HJ offers superior thermal integration via its cathode-connected mounting base, lowest Q_C × V_F, and highest I_FSM in DPAK form factor - making it optimal for high-power-density, high-reliability SMT power stages.

FAQ

Is PSC1065HJ suitable for automotive applications?

No. PSC1065HJ is not AEC-Q101 qualified and lacks automotive-specific testing, qualification, or warranty coverage. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for life-critical or safety-critical systems. For automotive use, consult Nexperia's dedicated AEC-Q101-certified SiC diode portfolio.

What is the recommended PCB layout for thermal performance?

Use ≥200 mm² of 2-oz copper connected directly to the mounting base (pin 1 and exposed pad), with ≥4 thermal vias (0.3 mm diameter, filled or plated) per cm² beneath the pad. Maintain ≥1.5 mm clearance from adjacent traces and avoid routing high-dI/dt paths over the pad to prevent inductive coupling and EMI.

Does PSC1065HJ require a gate resistor or snubber network?

No. As a unidirectional Schottky diode with zero reverse recovery charge, it has no gate and requires no external snubber. However, a small RC snubber (e.g., 10 Ω + 100 pF) across anode–cathode may be used empirically to damp high-frequency ringing caused by stray inductance in high-dI/dt layouts.

How does the R2P (Real-2-Pin) configuration affect circuit design?

The R2P configuration integrates the cathode into the mounting base, eliminating one discrete pin and reducing package inductance. This mandates that the cathode node be tied to the PCB ground plane or heatsink - precluding floating-cathode topologies like active clamp or certain bidirectional switch implementations unless isolated thermal interface materials are used.
