Product details
Overview
STPS5H100BY-TR from STMicroelectronics is an AEC-Q101-qualified 100 V, 5 A automotive-grade Schottky barrier rectifier in DPAK package, featuring 0.61 V max forward voltage at 125 °C and 5 A, -40 °C to +175 °C operating junction temperature, and negligible switching losses-designed for DC/DC converters and ECU power stages in engine control units.
For engineers reviewing the STPS5H100BY-TR datasheet, STPS5H100BY-TR pinout, STPS5H100BY-TR application, or STPS5H100BY-TR equivalent, key selection criteria include avalanche-rated reverse voltage stability across temperature, low leakage current (≤4.5 mA at 125 °C), thermal resistance (Rth(j-c) = 2.5 °C/W), and ECOPACK-compliant packaging for automotive production.
Technical Context
This high-frequency Schottky rectifier uses a planar silicon structure optimized for minimal reverse recovery charge and zero minority-carrier storage, enabling operation up to several MHz in SMPS topologies. Its avalanche-rated capability (518 W peak at 10 µs) and guaranteed VRRM over -40 °C to +175 °C support robust transient handling in automotive 12 V/24 V systems.
The device achieves a deliberate trade-off between forward voltage drop and leakage current: VF ≤ 0.61 V at 5 A/125 °C while limiting IR to 4.5 mA at VRRM/125 °C-enabling thermally stable performance in compact, unheatsinked ECU PCB layouts with copper area ≥ 20 cm².
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Guaranteed reverse blocking capability from -40 °C to +175 °C, suitable for 24 V automotive transients. |
| IF(AV) | 5 A at Tc = 165 °C - Continuous DC output current rating under real heatsink conditions. |
| VF (max) | 0.61 V at 5 A, 125 °C - Directly determines conduction loss: Pcond ≈ 0.51×IF(AV) + 0.02×IF(RMS)². |
| IR (max) | 4.5 mA at VRRM, 125 °C - Limits standby power loss in always-on ECU modules. |
| Rth(j-c) | 2.5 °C/W - Enables thermal design with minimal external heatsinking when mounted on ≥20 cm² copper. |
| PARM | 518 W at 10 µs - Supports single-pulse avalanche energy handling during load dump events. |
| Tj range | -40 °C to +175 °C - Meets under-hood ambient requirements without derating in engine bay applications. |
Pinout & Package
STPS5H100BY-TR is housed in a surface-mount DPAK (TO-252) package with three terminals: anode, cathode, and exposed thermal pad (cathode-connected). The package features UL94 V0 epoxy molding and is optimized for high-power density PCB mounting with solderable tab for enhanced thermal transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input current entry | Connected to input rail (e.g., battery or boost stage output); must withstand surge IFSM = 75 A. |
| Cathode (Pin 2) | Output current exit | Common node for output filter capacitor and load; electrically tied to thermal tab. |
| Thermal Pad (Tab) | Thermal & electrical cathode extension | Soldered directly to large copper pour; provides primary heat path (Rth(j-c) = 2.5 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive power electronics per stress test requirements including HTOL, TC, and UHAST. |
| Negligible switching losses | No reverse recovery charge (Qrr ≈ 0), eliminating turn-off loss and EMI in high-frequency DC/DC converters. |
| High Tj capability | Full specification maintained up to +175 °C junction temperature-critical for under-hood ECU placement. |
| Low leakage current | IR ≤ 4.5 mA at 100 V/125 °C ensures <10 mW standby dissipation in always-on vehicle networks. |
| ECOPACK compliance | Halogen-free, RoHS-compliant materials meet automotive environmental standards without performance compromise. |
Applications
| Engine Control Unit (ECU) | Automotive LED Lighting |
|---|---|
Use Scenario: Input rectification and freewheeling in 12 V–24 V buck-derived auxiliary power supplies within engine bay-mounted ECUs. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck converter secondary side; handles continuous 5 A DC current with minimal voltage drop. Use Value: Enables compact, heatsinkless layout due to Rth(j-c) = 2.5 °C/W and 175 °C Tj rating-reducing board area by >30% vs. standard Schottkys. | Use Scenario: Output rectification in constant-current LED drivers for headlamps and DRL modules. IC Role / Device Role / Timing Role: High-efficiency freewheeling path during PWM dimming cycles; operates at 100–500 kHz switching frequency. Use Value: 0.61 V VF at 125 °C reduces conduction loss by ~18% versus legacy 0.75 V parts-extending thermal margin for sealed LED housings. |
| Car Audio Power Supply | Start-Stop DC/DC Converter |
Use Scenario: Secondary-side rectification in Class-D amplifier DC/DC rails supplying 12–20 V to output stages. IC Role / Device Role / Timing Role: Low-noise, low-loss output diode in isolated flyback or forward converter delivering clean 15 V bias. Use Value: Negligible switching loss eliminates high-frequency ringing on audio supply rails-reducing audible noise and EMI filtering cost. | Use Scenario: Buck-boost rectifier in 12 V start-stop system power management, handling regenerative braking energy return. IC Role / Device Role / Timing Role: Bidirectional energy path component supporting both charging and discharging phases of supercapacitor buffer. Use Value: Avalanche rating (518 W @ 10 µs) sustains repeated load-dump transients without failure-ensuring >10-year field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS5L100D-TR | Lower VF (0.55 V typ. @ 5 A/25 °C) but higher IR (12 mA @ 125 °C); same DPAK package. | Better efficiency in cool environments; less suitable for high-ambient under-hood use due to leakage sensitivity. | Select when ambient Ta < 85 °C and leakage-driven standby loss is non-critical. |
| SB5100-E3/54 | Same 100 V/5 A rating but no AEC-Q101 qualification; Rth(j-c) = 3.0 °C/W; VF = 0.75 V max @ 125 °C. | Limited to non-safety-critical infotainment or body electronics-not approved for ECU or powertrain. | Acceptable only for cost-sensitive non-automotive industrial DC/DC where qualification is not required. |
Compared with STPS5L100D-TR and SB5100-E3/54, STPS5H100BY-TR uniquely balances low VF, controlled IR, full automotive qualification, and proven avalanche ruggedness-making it the only choice for thermally constrained, safety-critical engine bay power conversion.

FAQ
Is STPS5H100BY-TR pin-compatible with STPS5H100-Y?
Yes-STPS5H100BY-TR and STPS5H100-Y share identical DPAK package dimensions, terminal configuration (anode/cathode/tab), and thermal pad layout. The "-TR" suffix denotes tape-and-reel packaging (2500 pcs/reel); electrical and thermal specifications are fully identical per DS6906 Rev 3.
What is the maximum recommended PCB copper area for thermal management?
Per Figure 8 in DS6906 Rev 3, a minimum 20 cm² of 35 µm-thick copper under the thermal tab reduces Rth(j-a) to ~35 °C/W. For continuous 5 A operation at 125 °C ambient, ≥40 cm² is recommended to maintain Tj ≤ 155 °C without forced airflow.
Does this part support bidirectional current flow in start-stop systems?
No-STPS5H100BY-TR is a unidirectional Schottky rectifier. In start-stop DC/DC converters, it conducts only during energy transfer from input to output (forward bias). Reverse conduction is blocked; external MOSFETs or synchronous rectifiers handle regeneration paths.
How is avalanche capability verified and rated?
Avalanche energy is tested per JEDEC JESD24-11 using 10 µs pulses at Tj = 125 °C. ST guarantees 518 W peak power (PARM) under these conditions, validated across lot sampling. This rating supports single-event load dump survival but does not imply repetitive avalanche operation.
