Product details
Overview
STPSC16H065AW from STMicroelectronics is a 650 V, 16 A average forward current silicon carbide Schottky power rectifier in TO-247 package, featuring negligible reverse recovery, temperature-independent switching, and 1.56 V typical forward voltage at 25 °C. It operates up to 175 °C junction temperature and delivers high surge robustness (120 A IFSM, 10 ms) for hard-switching PFC stages in industrial AC-DC front-ends.
For engineers reviewing the STPSC16H065AW datasheet, STPSC16H065AW pinout, STPSC16H065AW application, or STPSC16H065AW equivalent, key selection criteria include zero-recovery behavior, low capacitive charge (41 nC), thermal resistance (0.95 °C/W typ.), and ECOPACK®2 compliance for high-efficiency, high-reliability power conversion designs.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-voltage rectification where reverse recovery losses dominate efficiency. Its wide bandgap enables stable 650 V blocking with no minority-carrier storage, eliminating turn-off ringing and enabling operation beyond 100 kHz without snubbers.
The device uses a planar Schottky structure on conductive SiC substrate, delivering temperature-invariant VF drift and minimal Cj variation (750 pF at 0 V, 76 pF at 300 V), making it suitable for boost PFC stages requiring consistent dynamic performance across -40 °C to +175 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in 400 VAC input PFC and 800 V DC bus systems with margin |
| IF(AV) | 16 A @ Tc = 115 °C - Sustains continuous conduction in 1–3 kW boost converters |
| VF (typ.) | 1.56 V @ IF = 16 A, Tj = 25 °C - Reduces conduction loss vs. Si FRD by ~40% at rated current |
| IFSM | 120 A @ tp = 10 ms, Tc = 25 °C - Withstands inrush and overload transients without failure |
| Rth(j-c) | 0.95 °C/W (typ.) - Supports thermal design with ≤100 W dissipation under forced convection |
| QCj | 41 nC @ VR = 400 V - Low capacitive charge minimizes switching loss in high-frequency operation |
| Tj (max.) | 175 °C - Allows compact heatsinking and operation in sealed industrial enclosures |
Pinout & Package
TO-247 package with isolated heat sink plane and three-terminal configuration: Anode (pin 1), Cathode (pin 2), and case-connected tab (pin 3). Mounting torque: 0.8 N·m recommended (max 1.0 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Current entry point during forward conduction | Connected to switch node in boost PFC; must handle high di/dt without parasitic inductance |
| Cathode (lead 2) | Current exit point during forward conduction | Connected to output capacitor; low-inductance layout critical for EMI control |
| Case (tab) | Thermal and electrical connection to cathode | Electrically tied to cathode; requires insulating washer if heatsink is grounded |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery | Eliminates reverse recovery charge (Qrr ≈ 0), removing switching loss and EMI spikes in hard-switched topologies |
| Temperature-stable VF | VF increases only ~0.42 V from 25 °C to 150 °C (1.56 → 1.98 V), enabling predictable loss modeling |
| High surge capability | 120 A non-repetitive surge withstand ensures reliability during cold-start and line-dip events |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements for industrial and automotive-qualified supply chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C4D15065A (Wolfspeed) | 15 A IF(AV), same 650 V VRRM, higher VF (1.7 V typ.), lower QCj (32 nC) | Slightly lower conduction loss at light load; less surge margin (100 A IFSM) | Prefer for ultra-high-frequency (>200 kHz) PFC where capacitive loss dominates |
| FFSH1565A (ON Semiconductor) | 15 A IF(AV), 650 V VRRM, VF = 1.65 V typ., Rth(j-c) = 1.1 °C/W | Higher thermal resistance limits power density; same TO-247 mechanical footprint | Choose when cross-compatible sourcing is required and 0.15 °C/W higher thermal impedance is acceptable |
Compared with C4D15065A and FFSH1565A, STPSC16H065AW offers superior surge robustness (120 A vs. ≤100 A) and lower thermal resistance (0.95 °C/W), making it optimal for high-reliability industrial PFC where transient immunity and thermal headroom are critical.

FAQ
Is STPSC16H065AW pin-compatible with standard silicon diodes in TO-247 packages?
Yes - STPSC16H065AW uses industry-standard TO-247 pinout (anode–cathode–case), matching legacy Si FRDs like STTH1606D. However, its cathode-connected case requires insulation from grounded heatsinks, unlike some Si diodes with isolated tabs.
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies IF(AV) = 16 A at Tc = 115 °C. For reliable long-term operation, keep Tc ≤ 115 °C under worst-case ambient and airflow conditions. Derating is required above this temperature per the IF vs. Tc curve (Figure 4).
Does STPSC16H065AW require a gate resistor or snubber network?
No - as a Schottky diode with no reverse recovery, it does not generate turn-off voltage spikes. Snubbers are unnecessary unless parasitic layout inductance causes ringing; gate resistors are irrelevant since it has no gate terminal.
How does its thermal resistance compare to competing SiC diodes?
At 0.95 °C/W (typical), STPSC16H065AW achieves among the lowest Rth(j-c) in its class - 0.2–0.3 °C/W better than C4D15065A and FFSH1565A - due to optimized die attach and copper tab construction in the TO-247 package.
