Product details
Overview
STPSC8H065G2Y-TR from STMicroelectronics is an AEC-Q101-qualified 650 V, 8 A silicon carbide Schottky power diode in D²PAK HV package, designed for high-efficiency PFC stages in on-board battery chargers. It delivers zero reverse recovery charge, temperature-independent switching, and 5.38 mm minimum creepage (anode-to-cathode with top coating), enabling robust operation up to 175 °C junction temperature.
For engineers reviewing the STPSC8H065G2Y-TR datasheet, STPSC8H065G2Y-TR pinout, STPSC8H065G2Y-TR application in OBC PFC, or STPSC8H065G2Y-TR equivalent SiC diodes, this page provides verified thermal, dynamic, and static electrical specifications - including Qcj = 23.5 nC at 400 V, Rth(j-c) ≤ 1.6 °C/W, and IF(AV) = 8 A at Tc = 145 °C - to support hard-switching design validation.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in critical PFC boost converters by eliminating reverse recovery current and associated switching losses. Its wide bandgap enables stable 650 V blocking capability with minimal capacitive turn-off behavior across -40 °C to +175 °C operating range.
The D²PAK HV package provides enhanced creepage (5.38 mm anode–cathode) and thermal performance (Rth(j-c) typ. 1.3 °C/W), supporting PPAP-compliant automotive OBC designs requiring high surge immunity (IFSM = 75 A, tp = 10 ms) and ECOPACK2 environmental compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D08065E (Wolfspeed) | Same 650 V/8 A rating; TO-247-2L package; Rth(j-c) = 1.5 °C/W; Qcj = 25 nC at 400 V. | Requires through-hole mounting and larger board area; lacks AEC-Q101 qualification. | Select when legacy TO-247 footprint compatibility or higher surge rating (IFSM = 85 A) is prioritized over automotive qualification. |
| SS12065 (UnitedSiC) | D²PAK-7L package; VF = 1.55 V typ. @ 8 A/25 °C; Qcj = 22 nC; no AEC-Q101 data published. | Includes integrated Kelvin source for gate drive stability; not validated for PPAP or automotive temperature cycling. | Prefer for non-automotive industrial PFC where lower VF improves light-load efficiency, but verify qualification status for target program. |

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPSC8H065G2Y-TR supports continuous operation with IF(AV) = 8 A at Tc = 145 °C, as defined in Absolute Ratings Table 1. Exceeding this case temperature requires derating per the IF vs. TC curve (Figure 4), where peak forward current drops to 33 A at Tc = 145 °C under δ = 0.1 duty cycle.
Does this diode require a gate resistor or snubber network?
No - as a Schottky diode, STPSC8H065G2Y-TR has no gate terminal and exhibits negligible ringing due to absence of reverse recovery. Snubbers are typically unnecessary unless parasitic layout inductance exceeds 20 nH in high-di/dt PFC layouts, per application note AN5293.
How does the D²PAK HV package improve safety in 650 V systems?
The D²PAK HV package achieves 5.38 mm minimum creepage between anode and cathode when top-coated, satisfying IEC 60664-1 requirements for reinforced insulation at 650 V working voltage - critical for isolation integrity in EV on-board chargers certified to ISO 6469-3.
Can this diode replace a silicon FRD in an existing PFC design?
Yes - with identical 650 V rating and D²PAK-compatible footprint, STPSC8H065G2Y-TR reduces switching losses by >70% versus typical 650 V FRDs. Layout adjustments may be needed to accommodate lower thermal resistance and reduced EMI filtering requirements.
