Product details

Overview

STPS2200U from STMicroelectronics is a 200 V, 2 A average forward current Schottky rectifier in SMB package, featuring 0.58 V typical forward voltage at 125 °C and 20 °C/W junction-to-lead thermal resistance. It serves as a low-loss freewheeling or polarity protection diode in high-frequency DC-DC converters and LED lighting power stages.

For engineers reviewing the STPS2200U datasheet, STPS2200U pinout, STPS2200U application, or STPS2200U equivalent, key selection criteria include forward voltage drop at operating temperature, surge current rating (100 A), thermal resistance, reverse leakage at 125 °C, and SMB package compatibility with FR4 PCB layouts.

Technical Context

This Schottky diode operates with negligible switching losses due to majority-carrier conduction and lacks minority-carrier storage delay. Its 200 V repetitive peak reverse voltage supports use in 100–120 VAC-derived offline supplies and 48 V intermediate bus architectures.

The device delivers stable conduction performance across -40 °C to +175 °C junction temperature range, with reverse leakage limited to 2.5 mA at 125 °C and VRRM. Thermal design relies on junction-to-lead resistance (20 °C/W for SMB) and PCB copper area for ambient thermal management.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	200 V - supports input rectification in 100–120 VAC SMPS and 48 V/60 V DC bus systems
IF(AV)	2 A - rated continuous forward current with square-wave duty cycle δ = 0.5 at lead temperature 145 °C
VF(typ)	0.58 V at Tj = 125 °C, IF = 2 A - enables <0.9 W conduction loss in high-efficiency LED drivers
Rth(j-l)	20 °C/W - defines thermal path from junction to SMB package leads; requires ≥1 cm² copper per lead for safe 2 A operation
IFSM	100 A - withstands 10 ms sinusoidal surge, suitable for inrush current handling in AC-DC front-ends
Tj(max)	+175 °C - allows operation in thermally constrained LED driver enclosures without derating below 2 A
IR(max)	2.5 mA at Tj = 125 °C, VR = 200 V - limits standby power loss in always-on lighting control circuits

Pinout & Package

STPS2200U is housed in an SMB (DO-214AA) surface-mount package with two terminals: cathode (K) and anode (A). The package uses gull-wing leads, epoxy body compliant with UL94 V0, and lead-free construction.

Pin/Terminal	Circuit Role	Design Meaning
A (Anode)	Forward current entry point	Connected to lower-potential side (e.g., switch node or ground return) in freewheeling paths
K (Cathode)	Forward current exit point	Connected to higher-potential rail (e.g., output capacitor positive or input supply) for unidirectional conduction

Key Features

Feature	Design Value
Low VF at high temperature	0.58 V typ at 125 °C enables >92% efficiency in 12 V → 5 V synchronous buck secondary-side rectification
Extremely fast switching	No reverse recovery time (trr ≈ 0 ns) eliminates switching loss and EMI in >500 kHz DC-DC converters
Low thermal resistance	20 °C/W junction-to-lead allows direct thermal coupling to PCB copper, reducing need for heatsinks
ECOPACK®2 compliance	Meets RoHS and halogen-free requirements for industrial and commercial LED lighting certifications

Applications

LED Lighting Power Supply

High-Frequency DC-DC Converter

Use Scenario: Constant-current LED driver with 24 V input and 36 V output string, operating at 300 kHz switching frequency.

IC Role / Device Role / Timing Role: Freewheeling diode in asynchronous buck topology, conducting during low-side switch off-time.

Use Value: 0.58 V VF at 125 °C reduces conduction loss by 35% versus standard PN diodes, improving thermal margin in enclosed fixtures.

Use Scenario: 48 V input to 12 V output telecom DC-DC module with tight thermal constraints.

IC Role / Device Role / Timing Role: Output rectifier in forward converter secondary, handling 2 A average load current.

Use Value: 20 °C/W Rth(j-l) enables full 2 A rating with only 2 cm² total copper area, eliminating discrete heatsink.

Input Polarity Protection

Low-Voltage Inverter Freewheeling

Use Scenario: 5 V/3.3 V USB-powered industrial sensor node with reverse-voltage risk during field wiring.

IC Role / Device Role / Timing Role: Series-connected anode-to-input protection diode blocking reverse current flow.

Use Value: 0.73 V VF at 25 °C ensures <150 mW dissipation at 200 mA fault current, avoiding thermal shutdown.

Use Scenario: 24 V battery-fed H-bridge motor controller with regenerative braking.

IC Role / Device Role / Timing Role: External freewheeling path across each half-bridge leg during PWM dead-time.

Use Value: Zero reverse recovery charge prevents shoot-through risk and reduces gate drive stress on MOSFETs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS220H	Same 200 V VRRM, 2 A IF(AV), but SMBflat package (Rth(j-l) = 15 °C/W); VF = 0.75 V typ at 25 °C	Better thermal performance in space-constrained layouts; slightly higher VF increases conduction loss at room temp	Select when PCB layout allows SMBflat footprint and junction temperature exceeds 125 °C routinely
MBR2200	200 V VRRM, 2 A IF(AV), DO-15 through-hole package; VF = 0.82 V typ at 25 °C; Rth(j-a) = 65 °C/W	Higher VF and worse thermal resistance limit usable current to ~1.2 A in SMT designs	Choose only for legacy through-hole assembly or where manual rework access is required

Compared with SS220H and MBR2200, STPS2200U offers optimal balance of low VF at elevated temperature, SMB footprint compatibility, and proven reliability in LED driver production-making it preferred for new SMT-based 24–48 V power stages.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The STPS2200U has a specified operating junction temperature range of -40 °C to +175 °C. Continuous operation at Tj = 175 °C is permitted when average forward current is maintained at or below 2 A with lead temperature held at 145 °C, per the absolute ratings table in the official datasheet.

Does STPS2200U have a specified reverse recovery time (trr)?

No-STPS2200U is a Schottky barrier diode and exhibits no minority-carrier storage. Its reverse recovery behavior is effectively instantaneous (trr ≈ 0 ns), confirmed by absence of trr specification in the datasheet and negligible switching losses cited in the features section.

Can STPS2200U be used in automotive applications?

ST does not qualify STPS2200U for automotive use. The datasheet explicitly states ST products are not designed or authorized for automotive environments unless expressly designated as such. This part lacks AEC-Q101 qualification and automotive-grade screening.

How does the SMB package compare thermally to SMBflat for STPS2200U variants?

The STPS2200U (SMB) has Rth(j-l) = 20 °C/W, while the STPS2200UF (SMBflat) achieves 15 °C/W due to enhanced thermal pad contact. SMBflat provides superior heat transfer in thermally demanding layouts, but SMB offers broader board-level compatibility and easier rework with standard gull-wing solder profiles.
