Product details
Overview
STPS8H100DEE-TR from STMicroelectronics is an 8 A, 100 V PowerFLAT-packaged Schottky rectifier optimized for high-frequency DC-DC converters and switch-mode power supplies. It delivers a typical forward voltage of 0.60 V at 125 °C/8 A, supports 175 °C maximum junction temperature, and features 4 °C/W junction-to-case thermal resistance for efficient thermal management in space-constrained inverters and polarity protection circuits.
For engineers reviewing the STPS8H100DEE-TR datasheet, STPS8H100DEE-TR pinout, STPS8H100DEE-TR application, or STPS8H100DEE-TR equivalent, key selection criteria include conduction loss modeling (P = 0.61×IF(AV) + 0.0088×IF²(RMS)), avalanche energy handling (480 W, 10 µs), and low-profile PowerFLAT 3.3×3.3 mm mounting compatibility with FR4 PCBs.
Technical Context
This Schottky rectifier operates as a unidirectional, low-loss freewheeling or output rectification device in synchronous and non-synchronous topologies. Its negligible reverse recovery charge and extremely fast switching enable operation above 500 kHz without significant switching losses, while its specified avalanche capability (480 W, 10 µs) allows safe transient energy absorption during inductive load commutation.
The device uses a planar Schottky barrier structure on silicon with metal-silicon interface engineered for stable VF vs. temperature behavior - typ. 0.60 V at 125 °C/8 A and 0.82 V at 25 °C/8 A - and low IR leakage (≤6 mA at 125 °C/VRRM), supporting reliable operation in automotive and industrial ambient environments up to 105 °C board temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 8 A average forward current at Tc = 150 °C - defines continuous DC output rectification capability in high-duty-cycle converters |
| VRRM | 100 V repetitive peak reverse voltage - sets maximum blocking voltage in buck, flyback, or half-bridge secondary-side applications |
| VF (typ.) | 0.60 V at 8 A, 125 °C - enables <1.5 W conduction loss per diode in 12 V/50 A systems using parallel devices |
| Tj (max.) | 175 °C - permits operation in under-hood automotive or sealed industrial enclosures without derating below 150 °C ambient |
| Rth(j-c) | 4 °C/W - allows direct heatsinking via exposed tab to copper area ≥2.2 cm² on FR4, enabling >6 W dissipation at ΔT = 25 °C |
| IFSM | 100 A non-repetitive surge (10 ms sine) - withstands inrush and fault currents in motor drive or UPS hold-up stages |
| PARM | 480 W repetitive avalanche power (10 µs pulse) - provides robustness against inductive kickback in relay drivers or solenoid controls |
Pinout & Package
Package: PowerFLAT 3.3 × 3.3 mm, surface-mount, single-sided thermal pad (cathode-connected tab). Exposed copper thermal pad occupies full bottom footprint (3.3 × 3.3 mm) and must be soldered to ≥2.2 cm² copper pour for rated thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top-side pad) | Forward current entry point | Connected to switching node (e.g., MOSFET drain in buck sync rectifier); requires low-inductance trace routing |
| Cathode (exposed bottom tab) | Forward current exit / thermal path | Electrically and thermally connected to system ground plane; must be fully soldered for Rth(j-c) = 4 °C/W compliance |
Key Features
| Feature | Design Value |
|---|---|
| Very low conduction losses | VF = 0.60 V @ 125 °C/8 A reduces power loss by ~35% vs. comparable 100 V Si PN diodes in 48 V telecom PSUs |
| Extremely fast switching | Negligible Qrr (<10 nC typical) eliminates reverse recovery spikes, enabling clean gate drive in synchronous rectifiers |
| Low thermal resistance | Rth(j-c) = 4 °C/W allows 6.5 W dissipation with only 25 °C rise above heatsink - critical for fanless industrial SMPS |
| Avalanche capacity specified | 480 W (10 µs) repetitive avalanche rating supports reliable operation in inductive load switching without external snubbers |
| ECOPACK2 compliant | Meets RoHS, halogen-free, and lead-free reflow requirements per JEDEC J-STD-020, qualified for automotive AEC-Q101 stress testing |
Applications
| DC-DC Converter Output Rectification | Automotive Body Control Module (BCM) Polarity Protection |
|---|---|
Use Scenario: 12 V → 3.3 V/15 A buck converter in infotainment head unit with strict EMI and thermal limits. IC Role / Device Role / Timing Role: Synchronous rectifier replacing MOSFET + driver; conducts during low-side switch ON phase. Use Value: 0.60 V VF at 125 °C cuts conduction loss by 1.2 W vs. Si diode alternative, reducing local hotspot temperature by 18 °C. | Use Scenario: Reverse-voltage protection on 12 V supply rail feeding microcontroller and CAN transceiver in door module. IC Role / Device Role / Timing Role: Series-blocking Schottky diode placed between battery input and downstream LDO. Use Value: 100 V VRRM withstands jump-start transients (up to 28 V) plus load-dump spikes; 6 mA IR at 125 °C ensures <100 µW standby loss. |

IC Role / Device Role / Timing Role: Shunt path activated when LED string opens, diverting full current around failed segment. Use Value: 8 A IF(AV) rating supports 3× overcurrent margin during fault; 175 °C Tj enables operation inside sealed LED housing at 95 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH10FN-M3/45 | Same 100 V VRRM, 8 A IF(AV), but TO-220AC package; Rth(j-c) = 2.5 °C/W, VF = 0.72 V @ 125 °C | Requires through-hole mounting and external heatsink; unsuitable for ultra-thin PCBs | Preferred where higher thermal margin outweighs board space constraints and assembly cost |
| ON Semiconductor SB8100 | PowerFLAT 5×6 mm; VF = 0.65 V @ 125 °C/8 A; Rth(j-c) = 3.5 °C/W; no avalanche rating specified | Larger footprint; lacks documented repetitive avalanche capability for inductive load reliability | Acceptable for non-inductive DC-DC outputs where transient robustness is not mission-critical |
Compared with VS-8EWH10FN-M3/45 and SB8100, STPS8H100DEE-TR uniquely balances ultra-low VF (0.60 V), compact PowerFLAT 3.3×3.3 mm footprint, and guaranteed 480 W avalanche rating - making it optimal for space-limited, high-reliability industrial and automotive DC-DC designs.

FAQ
What is the recommended PCB footprint for STPS8H100DEE-TR?
The official footprint is defined in Figure 10 of DS9077 Rev 4: a 3.3×3.3 mm thermal pad with 0.55–0.75 mm pitch outer pads. Minimum copper area under the tab is 2.2 cm² on 35 µm FR4; stencil aperture should match pad size with 100% paste coverage for void-free solder joints.
Does STPS8H100DEE-TR require a heatsink?
No discrete heatsink is required. The PowerFLAT package relies on PCB copper as the primary heatsink. With ≥2.2 cm² of 2-oz copper directly beneath the tab, it achieves Rth(j-a) ≈ 22 °C/W, enabling 6.5 W dissipation at 25 °C ambient rise - sufficient for most 8 A applications without added thermal mass.
Is STPS8H100DEE-TR suitable for automotive applications?
Yes. It is ECOPACK2-compliant, qualified per AEC-Q101, and rated for Tj = 175 °C. Its 100 V VRRM handles automotive load-dump transients (ISO 7637-2 Pulse 5a), and its avalanche rating supports inductive switching in BCMs and seat/mirror control units.
How is conduction loss calculated for STPS8H100DEE-TR?
Use the manufacturer-provided equation: P = 0.61 × IF(AV) + 0.0088 × IF²(RMS). For example, at IF(AV) = 8 A and IF(RMS) = 15 A (δ = 0.5 square wave), conduction loss = 0.61×8 + 0.0088×225 = 4.88 + 1.98 = 6.86 W - matching thermal test data in DS9077 Figure 1.
