Product details
Overview
STPS41H100CGY-TR from STMicroelectronics is a dual center-tap automotive Schottky rectifier in D²PAK (TO-263) package, rated for 100 V repetitive reverse voltage and 2 × 20 A average forward current per diode, with typical forward voltage of 0.62 V at 125 °C and 20 A - optimized for high-frequency DC/DC converters in engine control units and ADAS power supplies.
For engineers reviewing the STPS41H100CGY-TR datasheet, STPS41H100CGY-TR pinout, STPS41H100CGY-TR application, or STPS41H100CGY-TR equivalent, key selection criteria include avalanche-rated ruggedness (1300 W peak), AEC-Q101 qualification, low thermal resistance (1.5 °C/W junction-to-case per diode), and ECOPACK®2 compliance for automotive-grade reliability and environmental safety.
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 negligible switching losses stem from majority-carrier conduction and absence of minority-carrier storage delay.
Thermal design relies on conduction cooling via the exposed tab; junction temperature is limited to 175 °C, supported by Rth(j-c) = 1.5 °C/W per diode and coupling resistance Rth(c) = 0.1 °C/W between diodes. Avalanche capability is validated per ST AN1768 and AN2025 for transient overvoltage resilience in automotive load-dump conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports 42 V automotive systems with ≥2× margin against ISO 7637-2 pulse 5a (load dump up to 60 V). |
| IF(AV) per diode | 20 A - enables compact 100–200 W DC/DC stages without forced air cooling when mounted on ≥25 cm² copper area. |
| VF (Typ) | 0.62 V @ 125 °C, 20 A - reduces conduction loss to ~12.4 W per diode versus 1.2 V for Si PN rectifiers. |
| IR max | 10 µA @ 25 °C, 100 V - ensures minimal standby leakage in always-on vehicle modules. |
| Tj(max) | 175 °C - allows operation in under-hood environments near turbochargers or exhaust manifolds. |
| PARM | 1300 W @ 10 µs - withstands single-pulse avalanche energy during battery disconnect transients. |
| Rth(j-c) | 1.5 °C/W per diode - enables direct heatsink mounting with predictable thermal rise under 30 A RMS load. |
Pinout & Package
The STPS41H100CGY-TR uses a surface-mount D²PAK (TO-263) package with three terminals: two anodes (A1, A2) and one common cathode (K). The exposed metal tab is electrically connected to the cathode and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input node for first Schottky diode path; connects to primary-side switch node in center-tapped forward converter. |
| A2 | Anode 2 | Input node for second Schottky diode path; used for complementary phase in interleaved or push-pull topologies. |
| K | Common Cathode | Output node shared by both diodes; ties directly to output capacitor and ground plane for low-inductance return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use across -40 to +175 °C with 1000-cycle temperature cycling and 1000 h HTOL stress. |
| Avalanche rated | Rated for 1300 W peak repetitive avalanche power (tp = 10 µs), enabling robustness against inductive kickback in solenoid drivers. |
| Low VF/IR trade-off | 0.62 V @ 125 °C / 10 µA @ 25 °C - balances efficiency and leakage better than standard Schottky alternatives like STPS30L100CG. |
| ECOPACK®2 compliant | Lead-free, halogen-free, RoHS-compliant packaging meeting automotive ELV Directive requirements. |
| Dual center-tap topology | Reduces component count vs. discrete dual-diode solution; eliminates mismatch-induced imbalance in synchronous rectification. |
Applications
| Engine Control Unit (ECU) Power Supply | ADAS Camera Module DC/DC Converter |
|---|---|
Use Scenario: Regulating 12 V battery input to stable 3.3 V/5 V for microcontroller and CAN transceiver in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier in center-tapped forward converter operating at 200–500 kHz. Use Value: Reduces conduction loss by 45% vs. Si diode, lowering thermal load on ECU PCB and eliminating need for auxiliary heatsink. | Use Scenario: Powering image sensor and ISP in 77 GHz radar or surround-view camera modules with strict EMI limits. IC Role / Device Role / Timing Role: High-frequency rectifier in compact 12 V → 1.8 V/2.5 V isolated flyback with <100 ns recovery. Use Value: Negligible reverse recovery charge (Qrr ≈ 0) prevents switching node ringing and meets CISPR 25 Class 5 conducted emissions. |
| Electric Power Steering (EPS) Motor Driver | On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: Providing isolated 15 V gate drive supply for 3-phase inverter IGBTs in EPS control module. IC Role / Device Role / Timing Role: Output rectifier in 500 kHz resonant LLC auxiliary transformer secondary. Use Value: Withstands 175 °C junction temperature during sustained steering assist, avoiding thermal shutdown during peak torque events. | Use Scenario: Generating 12 V bias rail from high-voltage DC bus (400–800 V) for OBC control logic and communication ICs. IC Role / Device Role / Timing Role: Primary rectifier in flyback-derived auxiliary supply with 100 V VRRM derated for 600 V bus transients. Use Value: Avalanche rating absorbs 100 V+ spikes from HV bus switching, eliminating need for external TVS clamping. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30L100CG-TR | Lower IF(AV) (15 A per diode), higher VF (0.72 V typ @ 125 °C), same VRRM and package. | Suitable for ≤75 W auxiliary rails; insufficient for 20 A continuous ECU main rail. | Select when thermal budget allows higher VF and cost is prioritized over peak power density. |
| VS-42BA100-M3/4B | Single-diode TO-220AB package, 42 A total IF(AV), no center-tap configuration. | Requires two devices and external interconnection for center-tapped topology; higher layout inductance. | Choose only if legacy TO-220 footprint must be retained and dual-anode integration is not required. |
Compared with STPS30L100CG-TR and VS-42BA100-M3/4B, the STPS41H100CGY-TR uniquely delivers integrated dual-anode architecture with automotive-grade avalanche ruggedness and thermal performance in a space-saving D²PAK, making it optimal for new ECU and ADAS designs where board area and transient immunity are critical.

FAQ
Is STPS41H100CGY-TR pin-compatible with STPS41H100CTY?
No. STPS41H100CGY-TR uses a D²PAK (TO-263) surface-mount package with gull-wing leads and exposed cathode tab, while STPS41H100CTY uses through-hole TO-220AB with three separate leads and insulated mounting hole. Footprint, soldering method, and thermal interface differ fundamentally.
What is the maximum recommended PCB copper area for thermal management?
ST recommends ≥25 cm² of 2-oz copper connected to the cathode tab via multiple thermal vias (≥8 × 0.3 mm diameter) for operation at full 20 A per diode. With 10 cm², derating to 14 A per diode is required to maintain Tj ≤ 150 °C at 70 °C ambient.
Does STPS41H100CGY-TR support bidirectional current flow?
No. As a Schottky rectifier, it conducts only from anode to cathode. Reverse conduction is blocked above VRRM = 100 V, and no body diode or MOSFET channel exists to enable reverse current. It is unidirectional by semiconductor physics.
How is PPAP capability verified for this part?
PPAP Level 3 documentation - including design FMEA, process flow, control plan, dimensional results, and material certifications - is available upon request for STPS41H100CGY-TR. ST maintains full PPAP readiness per AIAG standards for all AEC-Q101-qualified automotive rectifiers.
