Product details
Overview
STPS20150CG from STMicroelectronics is a dual center-tap Schottky rectifier in D²PAK (TO-263) package, rated for 150 V repetitive peak reverse voltage and 2 × 10 A average forward current per diode at TC = 155 °C, with typical forward voltage drop of 0.69 V at 10 A and 25 °C - optimized for high-frequency switch-mode power supplies in telecom and industrial AC/DC adapters.
For engineers reviewing the STPS20150CG datasheet, STPS20150CG pinout, STPS20150CG application, or STPS20150CG equivalent, key selection criteria include its dual-diode center-tap configuration, 175 °C maximum junction temperature, insulated thermal performance (Rth(j-c) = 2.2 °C/W per diode), and ECOPACK®2 compliance for surface-mount high-power rectification.
Technical Context
This dual Schottky rectifier integrates two identical anode-common diodes in a single D²PAK package, enabling center-tap transformer secondary rectification without discrete pairing. Its low VF and low IR trade-off supports high-efficiency operation in 100–500 kHz SMPS topologies.
Thermal design leverages direct case conduction: Rth(j-c) = 2.2 °C/W per diode (D²PAK), with avalanche capability rated at 480 W (10 µs pulse, Tj = 125 °C). The insulated TO-220FPAB variant offers 2000 VRMS isolation, but STPS20150CG uses non-insulated D²PAK.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks up to 150 V reverse voltage per diode, suitable for 48 V–110 V input DC bus or 115 VAC-derived rails. |
| IF(AV) per diode | 10 A at TC = 155 °C - defines continuous DC output current capability per leg in thermally managed PCB layouts. |
| VF (typ) | 0.69 V at IF = 10 A, Tj = 25 °C - enables <1.4 W conduction loss per diode at 10 A, critical for >90% efficiency targets. |
| Tj(max) | +175 °C - allows operation in high-ambient environments (e.g., enclosed industrial PSUs) without derating below 155 °C case temp. |
| Rth(j-c) per diode | 2.2 °C/W - determines minimum copper area required under tab: ~30 cm² on 35 µm FR4 yields Rth(j-a) ≈ 25 °C/W. |
| IR (max) | 5.0 µA at 25 °C, 5.0 mA at 125 °C - low leakage preserves standby efficiency and prevents thermal runaway in parallel configurations. |
Pinout & Package
D²PAK (TO-263) package: surface-mount, 3-terminal outline with exposed metal tab (cathode common), UL 94 V0 epoxy, recommended footprint per Figure 11 (16.90 × 12.20 mm pad layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Cathode (common) | Electrically connected to heatsink; must be isolated from ground unless circuit requires cathode-referenced output. |
| Pin 2 | Anode 1 | First diode anode; connects to one end of center-tapped transformer secondary. |
| Pin 3 | Anode 2 | Second diode anode; connects to opposite end of center-tapped transformer secondary. |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | Rated for continuous operation up to +175 °C junction, enabling compact thermal design in space-constrained 1U power supplies. |
| Low VF / IR trade-off | 0.69 V VF (10 A) + 5 µA IR (25 °C) reduces both conduction loss and standby leakage vs. standard Schottkys. |
| Avalanche energy rating | 480 W peak avalanche power (10 µs, Tj = 125 °C) protects against inductive switching transients in flyback or forward converters. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and material declaration requirements for industrial and telecom equipment sustainability mandates. |
Applications
| Telecom AC/DC Adapters | Industrial 48 V Power Distribution |
|---|---|
|
Use Scenario: 115 VAC input, 48 V/20 A output flyback converter with center-tapped secondary. IC Role / Device Role / Timing Role: Dual Schottky rectifier providing synchronous full-wave rectification with shared cathode return path.

Use Scenario: Redundant 48 V DC-DC brick supplying backplane power in programmable logic controller (PLC) chassis. IC Role / Device Role / Timing Role: Center-tap rectifier converting isolated 52 VAC auxiliary winding into regulated 48 V bus with low EMI. Use Value: 175 °C Tj(max) ensures reliability during 70 °C ambient operation with no forced airflow, extending MTBF beyond 500,000 hours. |
| Server PSU Secondary Side | Medical Imaging Power Modules |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual center-tap Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH07 | Same VRRM (150 V), higher IF(AV) = 20 A/device, VF = 0.72 V @ 10 A, TO-247AC package (leadless, higher Rth(j-c) = 2.5 °C/W). | Requires larger heatsink due to TO-247 thermal resistance; better suited for lower-frequency (<100 kHz) designs with higher surge margin. | Select when surge current (IFSM = 220 A) and long-term thermal stability outweigh surface-mount assembly needs. |
| ON Semiconductor MBR20150CT | Identical ratings (150 V, 2×10 A), VF = 0.82 V @ 10 A, TO-220AB package (non-insulated, Rth(j-c) = 2.2 °C/W), no avalanche rating specified. | Lacks documented avalanche capability; unsuitable for unclamped inductive switching; through-hole only. | Choose for cost-sensitive, non-safety-critical 60 Hz line-powered supplies where layout permits through-hole mounting. |
Compared with VS-20CPH07 and MBR20150CT, STPS20150CG uniquely combines D²PAK surface-mount compatibility, verified 480 W avalanche robustness, and lowest VF (0.69 V) among 150 V dual Schottkys - making it optimal for high-density, high-reliability SMPS where thermal and transient margins are constrained.

FAQ
What is the pin configuration of STPS20150CG in D²PAK?
STPS20150CG has three terminals: Pin 1 is the common cathode (exposed metal tab), Pin 2 is Anode 1, and Pin 3 is Anode 2. The tab must be electrically connected to the cathode net and thermally coupled to PCB copper; no internal insulation exists between tab and cathode.
Does STPS20150CG support paralleling for higher current?
Yes - its matched dual-diode structure and low thermal resistance enable balanced current sharing when mounted on symmetric copper pours. Derate total IF(AV) by 15% for two devices in parallel due to thermal coupling; use Kelvin sensing traces for precision balancing.
How does the 175 °C Tj(max) impact thermal design?
The 175 °C rating allows sustained operation at 155 °C case temperature, meaning PCB copper area can be minimized: 25 cm² of 2-oz copper under the D²PAK tab achieves ~25 °C/W Rth(j-a), sufficient for 14 W dissipation with ≤50 °C ambient rise.
Is STPS20150CG suitable for automotive applications?
No - it is not AEC-Q101 qualified, lacks automotive-grade screening, and its datasheet specifies industrial temperature range only. For automotive 12 V/48 V systems, ST recommends AEC-Q101-certified alternatives like STPS30L15CW.
