Product details
Overview
STPS20H100CGY-TR from STMicroelectronics is an automotive-grade dual center-tap Schottky rectifier rated for 100 V repetitive peak reverse voltage, 2 × 10 A average forward current per diode at Tc = 160 °C, and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.59 V typ. at 10 A, 125 °C) and negligible switching losses, targeting high-frequency DC/DC converters in engine control units and ADAS power supplies.
For engineers reviewing the STPS20H100CGY-TR datasheet, STPS20H100CGY-TR pinout, STPS20H100CGY-TR application, or STPS20H100CGY-TR equivalent, key selection criteria include avalanche-rated ruggedness (780 W peak), AEC-Q101 qualification, thermal resistance (1.6 °C/W j-c per diode), low leakage (≤6 mA at 125 °C), and D²PAK package compatibility with board-level conduction cooling.
Technical Context
This dual-center-tap Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal, enabling synchronous rectification in half-bridge or center-tapped topologies. Its design emphasizes thermal robustness: junction-to-case resistance is 1.6 °C/W per diode, and coupling resistance between diodes is 0.15 °C/W, supporting parallel operation under asymmetric load conditions.
The device operates across –40 to +175 °C junction temperature, with avalanche capability validated per ST AN1768 and AN2025. Static characteristics are specified with pulse testing (tp = 380 µs for VF, tp = 5 ms for IR), ensuring relevance for SMPS transient behavior.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS20H100TV-TR | D²PAK package with standard marking; identical electrical specs but not PPAP-capable | Lacks PPAP documentation support for Tier 1 automotive production release | Select when AEC-Q101 qualification is required but PPAP is not mandated |
| VS-20CPH10-M3/45 | 100 V, 20 A dual common-cathode Schottky; Rth(j-c) = 1.8 °C/W, IR = 8 mA @ 125 °C | Higher leakage and thermal resistance reduce efficiency in high-ambient applications | Choose only if ST part is unavailable and thermal margin >15 °C exists |
Compared with STPS20H100TV-TR, the CGY-TR variant adds PPAP capability for production traceability; versus VS-20CPH10-M3/45, it offers lower VF, tighter IR, and superior thermal resistance-critical for compact, high-power-density automotive designs.

FAQ
What is the thermal resistance from junction to case per diode?
The junction-to-case thermal resistance is 1.6 °C/W per diode, measured with the cathode tab mounted to a large copper plane. This value assumes optimal soldering and thermal interface; actual performance depends on PCB copper area, thickness, and heatsink contact quality.
Is STPS20H100CGY-TR suitable for non-automotive industrial applications?
Yes-it meets industrial temperature requirements (–40 to +175 °C) and offers AEC-Q101 qualification, which exceeds typical industrial reliability standards. Its avalanche rating and low VF make it appropriate for high-reliability UPS, telecom, and railway power supplies where transient immunity is critical.
How does the dual center-tap configuration affect PCB layout?
The dual anode pins (1 and 2) and shared cathode tab require symmetrical trace routing to balance parasitic inductance. Anode traces must be equal length and width; the cathode tab must connect directly to a solid internal or bottom-layer copper pour ≥100 mm² for thermal and current return path integrity.
Does this device require a snubber circuit?
No snubber is needed due to zero reverse recovery charge. However, a small RC network (e.g., 10 Ω + 100 pF) across each anode-to-cathode path may be used to damp high-frequency ringing caused by layout parasitics in >1 MHz designs.
