Product details
Overview
PSC1665JJ from Nexperia is a 650 V, 16 A silicon carbide (SiC) Schottky diode in D2PAK R2P (SOT8018) package, engineered for high-efficiency power conversion with zero reverse recovery, temperature-independent switching, and low QC × VF figure-of-merit. It serves as a freewheeling or output rectifier in high-frequency DC-DC converters operating up to 175 °C junction temperature.
For engineers reviewing the PSC1665JJ datasheet, PSC1665JJ pinout, PSC1665JJ application, or PSC1665JJ equivalent, this device is selected for ultra-low-loss SMPS designs requiring robust surge handling (IFSM = 65 A), stable capacitance across temperature, and reduced EMI in server and photovoltaic inverter topologies.
Technical Context
This Merged PiN Schottky (MPS) diode combines SiC's wide-bandgap advantages with a real-2-pin configuration that ties the mounting base electrically to the cathode. Its zero-recovery behavior eliminates reverse recovery charge (Qrr = 0) and associated switching losses, enabling operation at >500 kHz without snubbers.
The device delivers stable dynamic performance across –55 °C to 175 °C: forward voltage drift is linearly modeled (VF = Vth + Rdiff × IF), and capacitive charge (QC = 34 nC at VR = 400 V) remains invariant with temperature-critical for consistent timing in resonant LLC and phase-shifted full-bridge converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Maximum repetitive reverse blocking voltage; enables use in 400 V AC-DC front-ends and 800 V DC bus systems with margin. |
| IF | 16 A continuous at Tc ≤ 120 °C - Sustains full rated current with case heatsinking; supports 500 W–1 kW power stages. |
| QC | 34 nC at VR = 400 V - Total capacitive charge determining turn-off energy loss; directly impacts EMI filter sizing and snubber design. |
| VF | 1.5–1.8 V at IF = 16 A, Tj = 25 °C - Low conduction loss enabling >98% efficiency in high-current synchronous rectification paths. |
| IFSM | 65 A (10 ms, half-sine, Tc = 150 °C) - High non-repetitive surge capability for inrush and fault conditions without bond-wire fusing. |
| Rth(j-c) | 1.3–1.7 K/W - Junction-to-case thermal resistance defining minimum heatsink requirement for thermal management. |
| VR leakage | 1 µA at 650 V, 25 °C - Ultra-low reverse leakage preserves efficiency in high-impedance hold-up circuits and battery-isolated systems. |
Pinout & Package
D2PAK R2P (SOT8018) surface-mount plastic package with real-2-pin configuration: anode and cathode terminals only; mounting base (mb) is internally connected to cathode and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Main current exit terminal; electrically tied to mounting base for low-inductance, low-thermal-resistance PCB layout. |
| 2 | A (anode) | Main current entry terminal; isolated from mounting base to enable floating anode configurations in bridge legs. |
| mb | Mounting base | Thermally conductive copper slug connected to cathode; requires soldered thermal pad on PCB for Rth(j-c) compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Zero forward & reverse recovery | Eliminates Qrr-related switching loss and di/dt-induced voltage overshoot, enabling hard-switched topologies without snubbers. |
| Temperature-independent QC | Capacitive charge remains stable from –55 °C to 175 °C, ensuring predictable turn-off timing and EMI profile across ambient extremes. |
| High IFSM (65 A) | Withstands 10 ms half-sine surge at 150 °C case temperature-supports robustness in UPS and PV inverter anti-islanding fault events. |
| Low QC × VF FoM | Optimized trade-off between conduction and switching loss; benchmark value for 650 V SiC Schottky diodes in high-frequency power supplies. |
| Reduced system EMI | No reverse recovery dv/dt spikes; measured diode capacitance (61 pF at 400 V) enables clean, predictable LC filter design. |
Applications
| Server Power Supply | Photovoltaic Inverter |

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 C4D16065A | Same 650 V/16 A rating but TO-247-2L package; higher Rth(j-c) (1.9 K/W); QC = 38 nC. | Requires larger heatsink footprint; less suitable for space-constrained SMD layouts. | Select when through-hole mounting and higher surge margin (IFSM = 80 A) are prioritized over board area. |
| ROHM SCT3160AL | 650 V/16 A in TO-263AB (D2PAK); QC = 32 nC but VF = 1.75 V @ 150 °C (vs. 2.6 V for PSC1665JJ). | Slightly lower conduction loss at high temperature; no integrated mounting base connection. | Select when lowest possible VF at elevated Tj is critical and discrete thermal pad routing is acceptable. |
Compared with C4D16065A and SCT3160AL, PSC1665JJ uniquely integrates cathode-to-mounting-base connectivity in D2PAK R2P, delivering lowest thermal resistance (1.3 K/W min) and highest surge robustness (65 A @ 150 °C) in a surface-mount form factor optimized for automated assembly.

FAQ
What is the maximum allowable case temperature for continuous operation?
The PSC1665JJ supports continuous forward current of 16 A at case temperature (Tc) ≤ 120 °C, as defined in the Quick Reference Data table. Exceeding this limit requires derating per Fig. 3 in the datasheet, where IF drops to 12 A at Tc = 135 °C under 0.5 duty cycle conditions.
Is the mounting base electrically isolated from the cathode?
No-the mounting base (mb) is internally connected to pin 1 (cathode), as confirmed in Table 2 (Pinning information) and the simplified outline graphic. This direct connection provides low-inductance, low-thermal-resistance current and heat transfer to the PCB thermal pad.
Does this diode exhibit reverse recovery charge (Qrr)?
No-this is a true Schottky-based Merged PiN Schottky (MPS) diode with majority-carrier conduction. The datasheet explicitly states "zero forward and reverse recovery" and confirms Qrr = 0 in both General Description and Features sections; only capacitive charge (QC = 34 nC) is present.
Can PSC1665JJ replace silicon fast recovery diodes in existing designs?
Yes-with layout and gate-drive adjustments: its zero Qrr eliminates snubber requirements, but its lower VF and faster switching demand careful evaluation of MOSFET body diode commutation and PCB parasitic inductance to avoid voltage ringing. Thermal interface must also accommodate the D2PAK R2P mounting base connection.
