Product details
Overview
STPSC6H065BY-TR from STMicroelectronics is an AEC-Q101-qualified 650 V, 6 A silicon carbide Schottky power diode in DPAK package, designed for high-efficiency PFC stages in automotive and industrial AC/DC converters. It exhibits zero reverse recovery charge, temperature-independent switching, and 175 °C maximum junction temperature. Its 1.45 V typical forward voltage at 6 A and 25 °C enables low conduction loss in continuous hard-switching operation.
For engineers reviewing the STPSC6H065BY-TR datasheet, STPSC6H065BY-TR pinout, STPSC6H065BY-TR application, or STPSC6H065BY-TR equivalent, key selection criteria include reverse leakage at 150 °C (≤250 µA), junction-to-case thermal resistance (max 2.4 °C/W), capacitive charge (18 nC at 400 V), and PPAP capability for automotive qualification workflows.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in boost PFC circuits by eliminating reverse recovery current and associated switching losses. Its wide bandgap substrate enables stable 650 V blocking with minimal capacitance variation over temperature and voltage.
The device operates with no minority-carrier storage, resulting in negligible ringing and EMI during turn-off. Its thermal performance-supported by a low Rth(j-c) of 1.6 °C/W (typ)-allows sustained 6 A average forward current at Tc = 145 °C without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Sustains full bridge rectified line voltage in universal-input 3-phase PFC designs |
| IF(AV) | 6 A at Tc = 145 °C - Supports continuous conduction mode (CCM) PFC output up to ~500 W |
| VF @ 6 A, 25 °C | 1.45 V (typ) - Enables <1.5 W conduction loss per diode in 6 A PFC leg |
| IR @ 150 °C, VR = VRRM | 250 µA (max) - Ensures low standby loss and stable voltage hold-off in high-temp environments |
| Qcj @ 400 V | 18 nC - Reduces turn-off dv/dt stress and gate driver loading in high-frequency (>100 kHz) PFC controllers |
| Rth(j-c) | 2.4 °C/W (max) - Allows direct mounting to heatsink with predictable thermal margin under 6 A DC load |
| Tj(max) | 175 °C - Enables operation in under-hood automotive PFC modules without active cooling |
Pinout & Package
STPSC6H065BY-TR uses the industry-standard DPAK (TO-252) thermally enhanced surface-mount package with exposed drain pad for low-thermal-resistance PCB mounting. The package complies with ECOPACK®2 environmental requirements and supports conduction cooling via the bottom thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry | Connected to PFC boost inductor node; requires low-inductance layout to minimize voltage overshoot |
| Cathode (Pin 2 & Tab) | Forward current exit / Heat path | Electrically and thermally connected to PCB copper pour; tab must be soldered to ≥100 mm² 2-oz copper for rated IF(AV) |
| Source (Pin 3) | Not applicable | This is a two-terminal diode; Pin 3 is unused and internally unconnected |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D06065E (Wolfspeed) | Same 650 V/6 A rating; higher VF (1.55 V typ @ 6 A); 2.0 °C/W Rth(j-c) (max) | Requires larger heatsink area for same Tj; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification need and thermal margin is abundant |
| SS16HE3_A/H (Vishay) | Silicon Schottky; only 60 V rating; 0.72 V VF; no high-temp stability beyond 125 °C | Unsuitable for >100 V PFC; limited to low-voltage DC/DC outputs | Only acceptable for non-PFC, low-voltage (<100 V) freewheeling where SiC benefits are unnecessary |
Compared with C3D06065E, STPSC6H065BY-TR offers tighter VF tolerance and automotive qualification; versus SS16HE3_A/H, it delivers 10.8× higher voltage rating and guaranteed 175 °C operation-enabling use in high-line PFC where silicon diodes fail catastrophically.

FAQ
What is the maximum allowable case temperature for continuous 6 A operation?
The datasheet specifies IF(AV) = 6 A at Tc = 145 °C. Operation at higher case temperatures requires derating per Figure 4; at Tc = 155 °C, peak forward current drops to ~52 A for δ = 0.1 duty cycle, but average current must be reduced below 6 A to maintain Tj ≤ 175 °C given Rth(j-c) limits.
Does STPSC6H065BY-TR require a gate resistor or snubber network?
No. As a Schottky diode with no minority carriers, it has no reverse recovery and negligible stored charge. Snubbers are unnecessary in properly laid-out PFC circuits. Gate resistors apply only to MOSFETs/IGBTs-not to this two-terminal diode.
Can this diode replace a standard silicon FRD in an existing PFC design without layout changes?
Yes, if the PCB footprint matches DPAK (TO-252) and thermal copper area is ≥100 mm². However, reduced switching loss may increase controller duty cycle slightly; verify loop stability and peak inductor current margins before full deployment.
Is the cathode pin electrically isolated from the thermal tab?
No. In STPSC6H065BY-TR, the cathode is internally bonded to the exposed metal tab (Pin 2). The tab must be connected to the cathode net on the PCB and cannot be used as a floating thermal pad-it is both electrical terminal and thermal path.
