Product details
Overview
STPS2200UF from STMicroelectronics is a 200 V, 2 A average forward current Schottky rectifier in SMBflat package, featuring 0.58 V typical forward voltage at 125 °C and 2 A, low thermal resistance (15 °C/W junction-to-lead), and operation up to 175 °C junction temperature. It is designed for high-frequency DC-DC converters, LED lighting freewheeling paths, and low-voltage polarity protection circuits.
For engineers reviewing the STPS2200UF datasheet, STPS2200UF pinout, STPS2200UF application, or STPS2200UF equivalent, key selection criteria include forward voltage drop at operating temperature, surge current capability (100 A), thermal impedance profile under pulsed conditions, and SMBflat footprint compatibility with FR4 PCB copper area constraints.
Technical Context
This Schottky diode uses a planar silicon structure optimized for minimal conduction and switching losses, with negligible reverse recovery charge (Qrr ≈ 0 nC) and fast unidirectional conduction. Its low VF and high Tj(max) enable high-efficiency operation in compact, thermally constrained power stages.
The SMBflat package provides enhanced thermal performance over standard SMB (Rth(j-l) = 15 °C/W vs. 20 °C/W), achieved via reduced leadframe thickness and optimized internal bond geometry - critical for sustained 2 A average current in ambient temperatures up to 85 °C with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input rails up to 170 VDC in offline SMPS or 48 V/60 V industrial DC systems with margin |
| IF(AV) | 2 A - delivers continuous output current in 12–24 V LED drivers or auxiliary supplies without forced air |
| VF(typ) | 0.58 V @ Tj=125°C, IF=2 A - reduces conduction loss to ~1.16 W, enabling >95% efficiency in 12 V buck outputs |
| Rth(j-l) | 15 °C/W - allows 30 °C temperature rise above lead at 2 A, simplifying thermal design on 100 cm² FR4 copper |
| IFSM | 100 A @ tp=10 ms - withstands inrush surges in hot-plug LED arrays or motor control flyback paths |
| Tj(max) | 175 °C - enables operation in sealed enclosures or high-ambient industrial lighting fixtures |
| IR(max) | 2.5 mA @ Tj=125°C, VR=200 V - ensures low leakage in high-impedance bias networks or sensing circuits |
Pinout & Package
The STPS2200UF is housed in an SMBflat (non-exposed pad) surface-mount package compliant with ECOPACK®2, UL94 V0 epoxy, and lead-free assembly. Dimensions: 5.60 × 3.95 × 1.10 mm (L × W × H), with 2.20 mm lead width and 0.40 mm minimum standoff.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to switching node (e.g., MOSFET drain) in synchronous rectifier or freewheeling path |
| Cathode (K) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; must be routed with low-inductance trace to minimize voltage overshoot |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high temperature | 0.58 V typ @ 125 °C - maintains efficiency in thermally saturated LED driver PCBs |
| Negligible switching losses | Zero Qrr and soft reverse recovery - eliminates snubber requirements in 300–500 kHz DC-DC stages |
| High surge robustness | 100 A IFSM - survives repeated cold-start surges in 24 V industrial lighting controllers |
| Thermally optimized SMBflat | 15 °C/W Rth(j-l) - enables 2 A continuous operation with <10 cm² total copper area per lead |
| ECOPACK®2 compliance | Lead-free, RoHS-compliant, halogen-free - meets EU and China RoHS 2.0 and JEDEC J-STD-020 reflow profiles |
Applications
| LED Lighting Driver | DC-DC Buck Converter Freewheeling |

Use Value: Fast switching (<10 ns) avoids commutation overlap losses during zero-crossing transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2H100UF | 100 V VRRM, same SMBflat package, 0.55 V VF @ 125 °C | Lower voltage rating limits use to ≤48 V systems; better VF for 12–24 V LED drivers | Select when input voltage is ≤36 V and lowest possible conduction loss is prioritized |
| SS210H | 100 V VRRM, SMB package, 0.85 V VF @ 25 °C, Rth(j-l) = 20 °C/W | Higher VF and thermal resistance reduce efficiency in thermally dense layouts | Choose only for cost-sensitive, low-power (<1 A), non-thermally constrained designs |
Compared with STPS2H100UF and SS210H, STPS2200UF uniquely balances 200 V capability, SMBflat thermal performance, and sub-0.6 V VF at elevated temperature - making it optimal for 24–48 V industrial LED and DC-DC applications requiring reliability across -40 to +85 °C ambient.

FAQ
What is the maximum allowable PCB copper area required for STPS2200UF to sustain 2 A continuous current at 70 °C ambient?
With 15 °C/W junction-to-lead thermal resistance and 1.16 W dissipation, a 30 °C temperature rise above lead is expected. Figure 8 shows Rth(j-a) drops to ~3.0 °C/W with ≥100 cm² total copper (50 cm² per lead). For 70 °C ambient and 175 °C max Tj, 40 cm² total copper (20 cm² per lead) is sufficient - verified via FR4 board test data in the datasheet.
Does STPS2200UF have a specified reverse recovery time (trr) or charge (Qrr)?
No - as a Schottky diode, STPS2200UF exhibits no minority-carrier storage, resulting in effectively zero reverse recovery time and Qrr. The datasheet confirms negligible switching losses and absence of reverse recovery waveforms, eliminating need for snubbers in 500 kHz+ topologies.
Can STPS2200UF replace STPS2200U in existing SMB footprint designs?
No - STPS2200UF uses SMBflat (non-exposed pad), while STPS2200U uses standard SMB. Though both share identical electrical specs, SMBflat has different land pattern dimensions (e.g., shorter L, no exposed thermal pad), requiring PCB redesign. Footprint compatibility is not guaranteed per Figures 10 and 12.
Is STPS2200UF qualified for automotive applications per AEC-Q101?
No - STPS2200UF is not AEC-Q101 qualified. The datasheet states it is intended for industrial and general-purpose power applications, with no automotive qualification testing performed. For automotive use, ST recommends the AEC-Q101-qualified STPS2200TV1 or STTH2R06.
