Product details

Overview

STPSC10C065RY from STMicroelectronics is a 650 V, 10 A average forward current silicon carbide (SiC) Schottky power diode in I²PAK package, qualified to AEC-Q101, with zero reverse recovery charge, temperature-independent switching, and 175 °C maximum junction temperature-designed for high-efficiency PFC stages in automotive on-board chargers and industrial AC-DC converters.

For engineers reviewing the STPSC10C065RY datasheet, STPSC10C065RY pinout, STPSC10C065RY application, or STPSC10C065RY equivalent, key selection criteria include its 26.4 nC capacitive charge at 400 V, 1.56 V typical forward voltage at 10 A/25 °C, 480 pF junction capacitance at 0 V, thermal resistance of 1.3 °C/W (typ), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in hard-switching PFC topologies by eliminating reverse recovery losses and associated EMI. Its wide bandgap enables stable 650 V blocking with low leakage (<425 µA at 150 °C) and minimal temperature drift in VF and Cj.

The device operates with no minority-carrier storage, delivering near-zero reverse recovery current (Qrr ≈ 0) and negligible turn-off ringing. Its junction-to-case thermal resistance (1.3 °C/W typ) supports high-power density mounting on heatsinks without forced air cooling in continuous conduction mode (CCM) PFC designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - Sustains full line voltage surges in universal-input 3-phase PFC and EV charger front-ends without breakdown.
I_F(AV)	10 A at T_c = 120 °C - Supports continuous conduction mode operation in 2–3 kW PFC stages with standard heatsinking.
V_F @ 10 A, 25 °C	1.56 V (typ) - Enables low conduction loss (≈15.6 W per diode at 10 A DC) and reduced thermal stress vs. Si FRD alternatives.
Q_Cj @ 400 V	26.4 nC - Defines stored capacitive energy during turn-off; directly impacts switching loss in totem-pole PFC gate drive requirements.
R_th(j-c)	1.3 °C/W (typ) - Allows direct thermal coupling to heatsink; enables >90% of rated power dissipation without derating at T_c ≤ 120 °C.
T_j(max)	175 °C - Permits operation in under-hood automotive environments and high-ambient industrial enclosures without thermal shutdown.
I_R @ 150 °C, V_RRM	425 µA (max) - Low leakage preserves efficiency in high-temperature boost diode position where Si devices exhibit exponential leakage rise.

Pinout & Package

The STPSC10C065RY is housed in an I²PAK (TO-263-2L) surface-mount package with isolated tab, epoxy rated UL 94 V0, and thermal path optimized for conduction cooling via the exposed drain pad.

Pin/Terminal	Circuit Role	Design Meaning
K (Pin 2)	Cathode	Main current output terminal; electrically connected to the metal tab for low-inductance, low-resistance thermal and electrical path to heatsink.
A (Pin 3)	Anode	Main current input terminal; routed to PFC boost inductor node; requires low-inductance PCB layout to minimize voltage overshoot.
NC (Pin 1)	No Connect	Internally unconnected lead; must remain floating-no PCB trace or solder connection permitted to avoid mechanical stress or parasitic coupling.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive power electronics including OBC, DC-DC, and traction inverters-meets stress testing for temperature cycling, HTRB, and ESD.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
C3D10065A (Wolfspeed)	Same 650 V/10 A rating; 1.7 V V_F (typ) at 10 A/25 °C; 28 nC Q_Cj; TO-247-2L package.	Higher thermal resistance (1.7 °C/W j-c); requires larger heatsink footprint; not AEC-Q101 qualified.	Select when cost sensitivity outweighs automotive qualification or when TO-247 mechanical fit is required.
SS10065 (ON Semiconductor)	650 V/10 A; 1.65 V V_F (typ); 25 nC Q_Cj; I²PAK package; AEC-Q101 qualified but PPAP not supported.	Limited documentation on surge capability (IFS_M not specified beyond 10 ms); no ECOPACK®2 compliance statement.	Select for non-automotive industrial PFC where PPAP and halogen-free compliance are not mandatory.

Compared with C3D10065A and SS10065, the STPSC10C065RY uniquely combines AEC-Q101 qualification, PPAP readiness, ECOPACK®2 compliance, and lowest R_th(j-c) (1.3 °C/W) in I²PAK-making it optimal for automotive and high-reliability industrial PFC where thermal performance and supply chain rigor are critical.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STPSC10C065RY supports continuous operation up to 120 °C case temperature (T_c) while delivering its full 10 A average forward current rating. At T_c = 120 °C, the junction temperature remains within the 175 °C limit assuming R_th(j-c) = 1.3 °C/W and power dissipation ≤13 W. Derating is required above this case temperature per Figure 4 in DS12402.

Is the I²PAK tab electrically isolated from the cathode?

No-the metal tab of the I²PAK package is internally connected to the cathode (Pin 2) and serves as both the primary thermal path and the main current-carrying terminal. PCB layout must treat the tab as a high-current cathode node, with appropriate copper area and thermal vias for heatsink attachment.

Does this diode require a gate resistor or snubber network?

No snubber or gate resistor is needed because the STPSC10C065RY has no reverse recovery charge (Q_rr ≈ 0) and exhibits negligible turn-off ringing. However, a small RC snubber (e.g., 10 Ω + 100 pF) may be used across anode-cathode in ultra-high dv/dt applications (>50 V/ns) to damp residual capacitive coupling.

Can STPSC10C065RY replace a silicon fast recovery diode in an existing PFC design?

Yes-pin-compatible replacement is possible in I²PAK footprints, but layout review is essential: reduce trace inductance due to faster switching, verify gate driver strength for coupled MOSFETs, and confirm thermal interface integrity since SiC runs cooler but concentrates heat at the tab. No circuit re-tuning is needed for basic CCM boost operation.
