Product details

Overview

STPSC12065G-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 STPSC12065G-TR datasheet, STPSC12065G-TR pinout, STPSC12065G-TR application, or STPSC12065G-TR equivalent, key selection criteria include its 5.38 mm minimum anode-to-cathode creepage (IEC 60664-1 compliant), 36 nC total capacitive charge at 400 V, and 0.85 °C/W typical junction-to-case thermal resistance - critical for high-reliability, high-voltage PFC and snubber circuits.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency switching topologies by eliminating reverse recovery charge (Q_rr ≈ 0) and associated switching losses. Its wide bandgap enables stable operation from –40 °C to +175 °C with negligible VF drift and no thermal runaway risk.

The D²PAK HV package provides enhanced isolation via 5.38 mm minimum creepage between anode and cathode terminals, supporting reinforced insulation requirements in 650 V systems. Its low C_j (750 pF at 0 V) and Q_Cj (36 nC at 400 V) minimize capacitive turn-off losses and EMI generation during hard-switching.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - supports primary-side rectification and boost PFC in 400 V AC input systems with margin for transients
I_F(AV)	12 A at T_C = 145 °C - defines continuous conduction capability under real heatsink conditions
V_F (typ.)	1.30 V at I_F = 12 A, T_j = 25 °C - sets conduction loss baseline: ~15.6 W at full load using P = 1.02×I_F(AV) + 0.065×I_F(RMS)²
R_th(j-c) (typ.)	0.85 °C/W - enables direct thermal path to heatsink; allows 135 °C ΔT rise at 15.9 W dissipation
Q_Cj	36 nC at V_R = 400 V - determines capacitive turn-off energy loss and dv/dt-induced displacement current
C_j	750 pF at V_R = 0 V - contributes to high-frequency impedance and EMI filter design in snubber networks
T_j(max)	175 °C - permits operation in sealed enclosures or high-ambient environments without derating penalties

Pinout & Package

Housed in D²PAK HV (High Voltage) package, this device features a single anode and single cathode terminal layout optimized for high-voltage isolation. The package meets UL94 V0 flammability rating and provides 5.38 mm minimum creepage distance between anode and cathode when top-coated per IEC 60664-1.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Tab)	High-side power input node	Electrically connected to metal tab; requires insulated mounting or isolated heatsink for floating applications
Cathode (Lead)	Low-side power output node	Standard gull-wing lead; carries full forward current and must be routed with low-inductance layout

Key Features

Feature	Design Value
No reverse recovery (Q_rr ≈ 0)	Eliminates switching loss spikes and ringing in hard-switched PFC, reducing EMI filter size and MOSFET stress
Temperature-stable VF and C_j	Forward voltage increases only ~0.15 V from 25 °C to 175 °C; capacitance variation < ±15% across operating range
D²PAK HV creepage ≥ 5.38 mm	Enables reinforced insulation in 650 V systems without additional PCB spacing or potting
175 °C maximum junction temperature	Supports high-power density designs with reduced heatsink mass and extended lifetime in automotive and industrial environments
ECOPACK2 compliance	Meets RoHS, halogen-free, and material declaration requirements for global environmental regulations

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-TR	Same 650 V / 10 A rating; 1.55 V V_F (typ.) at 10 A; TO-247 package; R_th(j-c) = 0.75 °C/W	Higher V_F increases conduction loss by ~2.1 W at 10 A; larger footprint limits board density	Select for higher thermal performance where heatsink interface dominates loss budget
SS12065A-TR	650 V / 12 A; 1.40 V V_F (typ.) at 12 A; D²PAK package; no HV creepage spec; R_th(j-c) = 1.05 °C/W	Lacks 5.38 mm creepage; unsuitable for IEC 60664-1 reinforced insulation; higher thermal resistance	Select only for cost-sensitive, non-safety-critical 650 V applications with adequate PCB spacing

Compared with C3D10065A-TR and SS12065A-TR, STPSC12065G-TR uniquely balances low V_F, industry-leading creepage, and D²PAK HV manufacturability - making it optimal for certified, space-constrained PFC modules requiring both efficiency and safety compliance.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STPSC12065G-TR supports continuous operation at case temperatures up to 145 °C, as validated by its I_F(AV) = 12 A rating under that condition. Exceeding 145 °C requires derating per the I_F vs. T_C curve in Figure 3 of DS11623, with absolute maximum junction temperature limited to 175 °C regardless of case temperature.

Does this diode require a gate resistor or external snubber circuit?

No - the STPSC12065G-TR is a two-terminal uncontrolled diode with no gate. Its zero reverse recovery eliminates the need for RC snubbers typically used with silicon FRDs. However, an RCD snubber may still be used for voltage clamping in high-di/dt inductive switching environments, independent of diode recovery behavior.

How does the D²PAK HV package differ from standard D²PAK in layout and assembly?

The D²PAK HV variant uses extended leadframe spacing and modified mold compound geometry to achieve 5.38 mm minimum creepage between anode (tab) and cathode (lead). Its recommended footprint (Figure 13) has wider anode–cathode separation and different solder pad dimensions versus standard D²PAK - requiring dedicated stencil and placement files to ensure isolation integrity.

Can STPSC12065G-TR replace silicon diodes in existing 650 V designs without layout changes?

Direct replacement is possible only if the PCB layout accommodates D²PAK HV's larger anode–cathode clearance and revised footprint. Standard D²PAK footprints do not meet the 5.38 mm creepage requirement. Thermal and electrical improvements (e.g., lower V_F, no Q_rr) are realized immediately, but safety certification requires revalidation of creepage/clearance distances.
