Product details
Overview
STPSC20H12G2-TR from STMicroelectronics is a 20 A, 1200 V silicon carbide (SiC) Schottky power diode in D²PAK HV package, designed for high-efficiency PFC, EV charging stations, and DC/DC converters. It delivers zero reverse recovery, temperature-independent switching, 1.35 V typical forward voltage at 20 A and 25 °C, 5.38 mm minimum anode-to-cathode creepage, and operation up to 175 °C junction temperature.
For engineers reviewing the STPSC20H12G2-TR datasheet, STPSC20H12G2-TR pinout, STPSC20H12G2-TR application, or STPSC20H12G2-TR equivalent, key selection criteria include hard-switching robustness, conduction loss modeling (P = 1.07×IF(AV) + 0.059×IF²(RMS)), IEC 60664-1 creepage compliance, and surge capability under transient conditions (140 A @ 10 ms, Tc = 25 °C).
Technical Context
This SiC Schottky diode eliminates minority-carrier storage and reverse recovery charge, enabling clean turn-off with negligible ringing in high-frequency hard-switching topologies. Its wide bandgap enables stable 1200 V blocking with low VF drift across -40 °C to +175 °C.
Thermal performance is optimized via low Rth(j-c) (0.30–0.45 °C/W) and high surge current rating (140 A non-repetitive, 10 ms sinusoidal), supporting reliable operation in thermally demanding industrial power stages without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Enables direct use in 1000 V DC bus systems with 20% safety margin per IEC 62109. |
| IF(AV) | 20 A @ Tc = 155 °C - Sustains continuous conduction in PFC boost stages with standard heatsinking. |
| VF (typ.) | 1.35 V @ IF = 20 A, Tj = 25 °C - Reduces conduction loss vs. Si fast recovery diodes by ~40% at same current. |
| IR (max) | 800 µA @ VR = 1200 V, Tj = 150 °C - Ensures low leakage in high-temperature EV charger environments. |
| Rth(j-c) | 0.45 °C/W (max) - Allows thermal design with ≤9 W dissipation for ΔTjc ≤ 4.05 °C at rated IF(AV). |
| Cj | 1650 pF @ VR = 0 V - Low capacitance minimizes switching loss and EMI in >100 kHz PFC designs. |
| Qcj | 129 nC @ VR = 800 V - Quantifies capacitive turn-off charge; enables accurate snubber and gate driver sizing. |
Pinout & Package
Housed in D²PAK HV (TO-263HV) package with creepage-optimized layout: isolated anode (pin 1), cathode (pin 2), and exposed thermal tab (pin 3, electrically connected to cathode). Creepage distance between anode and cathode is ≥5.38 mm with conformal coating, meeting IEC 60664-1 requirements for reinforced insulation at 1200 V.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | High-voltage input node in boost PFC; requires isolation clearance ≥5.38 mm to cathode. |
| Pin 2 (Cathode) | Cathode connection | Output node tied to switching node; electrically common with thermal tab for low-inductance layout. |
| Pin 3 (Tab) | Thermal pad / Cathode | Primary heat path to PCB copper; must be soldered to ≥30 cm² of 35 µm Cu for Rth(j-a) ≤ 35 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery | Eliminates recovery-related switching losses and EMI in hard-switched totem-pole PFC. |
| Temperature-stable VF | VF increases only ~0.4 V from 25 °C to 150 °C - enables predictable loss budgeting across ambient range. |
| D²PAK HV creepage | 5.38 mm min. anode-to-cathode spacing - supports reinforced insulation for 1200 V DC systems per IEC 60664-1. |
| High surge capability | 140 A non-repetitive surge (10 ms, Tc = 25 °C) - withstands inrush and fault currents in EVSE front-end stages. |
| ECOPACK2 compliance | Halogen-free, RoHS-compliant packaging - meets EU environmental directives for industrial and automotive applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D20120D | Same 20 A/1200 V rating; TO-247 package; higher Rth(j-c) (0.65 °C/W); VF = 1.5 V typ. | Requires larger heatsink area; less suitable for space-constrained D²PAK layouts. | Prefer when mechanical mounting flexibility outweighs thermal density needs. |
| UJ3D20120K | Kelvin-source TO-247-4L package; lower VF (1.25 V typ.); includes dedicated sense pin for accurate current monitoring. | Enables closed-loop current control in advanced PFC; not pin-compatible with D²PAK footprint. | Choose when precision conduction loss measurement or adaptive control is required. |
Compared with C3D20120D and UJ3D20120K, STPSC20H12G2-TR offers superior thermal density (Rth(j-c) ≤ 0.45 °C/W) and creepage-optimized D²PAK HV packaging-making it optimal for compact, high-reliability EVSE and industrial PFC where board space and IEC 60664-1 compliance are critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPSC20H12G2-TR supports continuous operation at Tc = 155 °C for its rated IF(AV) = 20 A. At this case temperature, junction temperature remains within the absolute maximum limit of 175 °C when Rth(j-c) ≤ 0.45 °C/W and power dissipation is ≤9 W. Derating is required above 155 °C case temperature.
Does this diode require a gate resistor or snubber network?
No. As a Schottky diode with no minority carriers, STPSC20H12G2-TR exhibits no reverse recovery and negligible turn-off ringing. Snubbers are unnecessary in properly laid-out PCBs with controlled loop inductance. Gate resistors do not apply - this is a two-terminal passive device, not a MOSFET or IGBT.
How does the D²PAK HV package differ from standard D²PAK?
The D²PAK HV variant features extended creepage distances (5.38 mm anode-to-cathode vs. ~3.5 mm in standard D²PAK), reinforced mold compound meeting UL94 V0, and modified leadframe geometry to isolate high-voltage terminals. These changes enable safe operation at 1200 V DC with reinforced insulation per IEC 60664-1.
Can STPSC20H12G2-TR replace a silicon fast recovery diode in an existing design?
Yes - with layout review. Its lower VF reduces conduction loss, but its lower stored charge demands tighter control of parasitic inductance to avoid voltage overshoot. Verify PCB trace inductance, update snubber components (if present), and confirm thermal interface to the tab meets D²PAK HV requirements before drop-in replacement.
