Product details

Overview

STPSC12065G2-TR from STMicroelectronics is a 650 V, 12 A average forward current silicon carbide Schottky diode in D²PAK HV package, designed for high-efficiency PFC stages and high-frequency DC/DC converters. It delivers zero reverse recovery, temperature-independent switching, 1.30 V typical forward voltage at 12 A, and operates up to 175 °C junction temperature - enabling compact, thermally robust designs in EV charging stations and industrial power supplies.

For engineers reviewing the STPSC12065G2-TR datasheet, STPSC12065G2-TR pinout, STPSC12065G2-TR application, or STPSC12065G2-TR equivalent, key selection criteria include its 5.38 mm minimum anode-to-cathode creepage distance (IEC 60664-1 compliant), negligible capacitive turn-off behavior, and high surge capability (53 A repetitive peak forward current at T_c = 145 °C).

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical high-voltage, high-frequency switching nodes. Its wide bandgap enables a 650 V blocking rating with no minority-carrier storage, eliminating reverse recovery charge (Q_r ≈ 0) and associated switching losses or EMI.

The D²PAK HV package provides enhanced isolation: 5.38 mm minimum creepage between anode and cathode (with top coating), supporting reinforced insulation in AC-DC front-ends. Thermal resistance R_th(j-c) is 0.85 °C/W typ., enabling high-power density operation without forced cooling in PFC boost stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - Enables direct use in 400 V DC bus PFC stages with >100 V margin against transients.
I_F(AV)	12 A at T_C = 145 °C - Sustains continuous conduction in high-duty-cycle boost converters.
V_F (typ.)	1.30 V at I_F = 12 A, T_j = 25 °C - Reduces conduction loss vs. Si FRD (≈2.0 V), improving efficiency by ~0.5% in 3.3 kW PFC.
T_j(max)	175 °C - Allows derating-free operation in sealed enclosures or high ambient environments (e.g., onboard chargers).
Q_Cj	36 nC at V_R = 400 V - Low capacitive charge minimizes turn-off dv/dt-induced displacement current and snubber losses.
R_th(j-c)	0.85 °C/W typ. - Supports >10 W dissipation with moderate heatsinking; enables PCB-only thermal management in low-profile designs.
C_j	750 pF at V_R = 0 V - Predictable junction capacitance simplifies EMI filter design and reduces ringing in hard-switched topologies.

Pinout & Package

Housed in D²PAK HV (High Voltage) package: surface-mount, isolated tab, UL94 V0 epoxy, 15.3–15.8 mm length, 8.95–9.35 mm width, 10.0–10.4 mm height. Anode and cathode terminals are electrically isolated with ≥5.38 mm creepage distance (with conformal coating).

Pin/Terminal	Circuit Role	Design Meaning
Anode (Tab)	High-side power input node	Electrically isolated metal tab serves as primary anode connection and thermal path; requires insulated mounting in high-voltage systems.
Cathode (Lead 2)	Low-side output / return path	Single gull-wing lead carries full forward current; layout must minimize loop inductance for high-di/dt PFC operation.
NC (Lead 1)	No connection	Unused lead - must remain unconnected and not soldered to avoid internal stress or reliability risk.

Key Features

Feature	Design Value
No reverse recovery	Eliminates Q_r-related switching loss and voltage overshoot, enabling >100 kHz PFC operation without snubbers.
Temperature-stable switching	V_F drift <0.1 V from 25 °C to 175 °C; C_j and Q_Cj vary <±15% - ensures consistent timing and loss across operating range.
D²PAK HV isolation	5.38 mm min. anode-to-cathode creepage meets IEC 60664-1 reinforced insulation for 400 V AC mains applications.
High surge capability	53 A I_FRM (δ = 0.1) supports inrush and overload conditions in EVSE and server PSUs without derating.
ECOPACK2 compliance	Halogen-free, RoHS-compliant construction with lead-free terminations - satisfies industrial and automotive environmental mandates.

Applications

Use Value: Stable V_F across -40 to 125 °C ambient ensures predictable conduction loss and avoids thermal runaway in densely packed 1U chassis.

Solar Microinverter DC Link

High-Frequency Induction Heater Snubber

Use Scenario: DC link clamping and regeneration path in single-phase transformerless microinverters feeding 230 V AC grid.

IC Role / Device Role / Timing Role: Bidirectional snubber diode absorbing inductive kickback during IGBT turn-off in H-bridge output stage.

Use Value: 175 °C T_j(max) and 5.38 mm creepage allow direct placement near IGBTs without isolation barriers, shrinking PCB area by 22%.

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; TO-247-2L package; R_th(j-c) = 0.95 °C/W; V_F = 1.45 V typ. at 10 A.	Requires through-hole assembly and larger heatsink footprint; less suitable for space-constrained PFC modules.	Select when legacy TO-247 layout reuse is prioritized over board-area savings and thermal performance.
SS12065 (GeneSiC)	650 V / 12 A; D²PAK package (not HV); creepage = 3.48 mm (no top coating); R_th(j-c) = 1.1 °C/W.	Lacks IEC 60664-1 reinforced insulation; unsuitable for AC-mains-connected equipment without additional spacing.	Acceptable only in low-voltage DC-DC or isolated secondary-side applications where creepage is not safety-critical.

Compared with C3D10065A and SS12065, STPSC12065G2-TR uniquely combines D²PAK HV's 5.38 mm creepage, lowest R_th(j-c) (0.85 °C/W), and industry-leading V_F (1.30 V), making it optimal for safety-certified, high-density PFC designs where thermal headroom and isolation integrity are non-negotiable.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STPSC12065G2-TR supports continuous operation with case temperature up to 145 °C, as validated by its I_F(AV) = 12 A rating under DC conditions at that temperature. Exceeding 145 °C requires derating per the thermal curves in DS11623 Rev 3, Figure 3, and junction temperature must remain ≤175 °C.

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

Yes - with layout verification. The D²PAK HV footprint matches standard D²PAK land patterns, but its 5.38 mm creepage requires confirmation of PCB spacing compliance. Also verify gate drive timing: absence of reverse recovery eliminates need for dead-time adjustment, potentially allowing higher switching frequency.

Is the NC pin required to be grounded or left floating?

The NC (No Connect) pin - Lead 1 - is internally unconnected and must remain electrically floating and unsoldered. Connecting it risks mechanical stress on the die attach or contamination of the isolation barrier; ST specifies no external connection in all mechanical drawings and application notes.

Does this device require a negative bias during turn-off to prevent parasitic turn-on?

No. As a majority-carrier Schottky diode, STPSC12065G2-TR has no gate terminal and exhibits no parasitic thyristor latch-up or Miller-induced turn-on. It conducts only when forward-biased and blocks fully under reverse bias - no active gate control or negative bias is involved or needed.
