Product details
Overview
STPS20150CFP from STMicroelectronics is a dual-center-tap Schottky rectifier in TO-220FPAB insulated package, rated for 150 V repetitive reverse voltage and 2 × 10 A average forward current per diode at TC = 135 °C, with typical forward voltage drop of 0.69 V at 10 A and 25 °C. It delivers low conduction loss and avalanche-rated ruggedness for high-frequency switch-mode power supplies in industrial AC/DC adapters and server PSUs.
For engineers reviewing the STPS20150CFP datasheet, STPS20150CFP pinout, STPS20150CFP application, or STPS20150CFP equivalent, key selection criteria include its 2000 VRMS insulation rating, 4.5 °C/W junction-to-case thermal resistance (per diode), 175 °C max junction temperature, and ECOPACK®2 compliance - critical for thermally constrained, safety-isolated, and environmentally regulated power designs.
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode diodes sharing a common cathode terminal (center-tap configuration), enabling synchronous rectification or dual-output DC/DC conversion. Its low VF and low IR trade-off is optimized for efficiency in 100–500 kHz SMPS topologies.
The TO-220FPAB package provides reinforced electrical isolation (2000 VRMS) between mounting tab and internal die, eliminating need for insulating washers in grounded heatsink applications. Thermal coupling between diodes is characterized via Rth(c) = 2.5 °C/W, enabling accurate parallel-loss modeling under asymmetric load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - supports input rectification up to 100 VAC RMS with margin for line surges in universal-input SMPS. |
| IF(AV) per diode | 10 A at TC = 135 °C - defines continuous output current capability per leg when mounted on heatsink with controlled case temperature. |
| VF(typ) @ 10 A | 0.69 V at 25 °C - enables <1.4 W conduction loss per diode at 10 A, reducing thermal load vs. standard silicon rectifiers. |
| IR(max) @ 125 °C | 5.0 mA at VR = 150 V - limits standby leakage in high-temperature environments without compromising efficiency. |
| Rth(j-c) per diode | 4.5 °C/W - determines minimum heatsink requirement: ~10 °C rise per 2.2 A RMS current in steady-state operation. |
| Tj(max) | 175 °C - allows operation in sealed enclosures or high-ambient industrial settings without derating below full current. |
| Insulation rating | 2000 VRMS - satisfies basic insulation requirements per IEC 60950-1 and IEC 62368-1 for secondary-side rectification. |
Pinout & Package
TO-220FPAB package features electrically isolated metal tab (pin 3), with pins 1 and 2 serving as anode terminals for each diode; cathodes are internally joined and connected to the insulated tab. Mounting screw contact is safe for direct connection to grounded heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first rectifier leg; routed to primary-side switching node in center-tap forward converter. |
| Pin 2 | Anode of Diode 2 | Input node for second rectifier leg; enables dual-output or interleaved synchronous rectification. |
| Tab (Pin 3) | Common Cathode (isolated) | Output node shared by both diodes; electrically isolated from heatsink - no insulator required. |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche energy rating | 480 W peak (tp = 10 µs) - withstands transient overvoltage events without failure during MOSFET turn-off spikes. |
| High Tj capability | 175 °C max junction temperature - extends lifetime in thermally aggressive environments like enclosed power modules. |
| Low VF / IR trade-off | 0.69 V @ 10 A / 5 mA @ 150 V, 125 °C - balances efficiency and leakage better than generic Schottkys in same voltage class. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy and lead finish - meets IPC-1752A Tier 1 reporting and EU environmental mandates. |
| Insulated TO-220FPAB | 2000 VRMS isolation - eliminates creepage/clearance design overhead and reduces BOM cost vs. adding external isolators. |

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, but TO-220AB (non-insulated); Rth(j-c) = 2.2 °C/W per diode. | Requires insulating kit for grounded heatsink; better thermal performance but adds assembly cost and risk of insulation failure. | Select when heatsink is floating or isolation is handled elsewhere; avoid in Class I medical or telecom systems requiring reinforced insulation. |
| ON Semiconductor MBR20150CT | Same TO-220AB package, identical VRRM/IF ratings, but VF = 0.86 V @ 10 A (typ), no avalanche rating specified. | Lacks documented avalanche ruggedness and has higher conduction loss; not qualified for surge-prone telecom or industrial mains-connected equipment. | Acceptable for cost-sensitive consumer adapters with low surge exposure; unsuitable where transient immunity or efficiency >92% is required. |
Compared with VS-20CPH07 and MBR20150CT, STPS20150CFP uniquely combines certified 2000 VRMS isolation, 480 W avalanche rating, and 0.69 V VF - making it the only option among the three qualified for safety-critical, high-reliability, and thermally constrained isolated power applications without design compromises.

FAQ
What is the maximum continuous forward current per diode for STPS20150CFP at 135 °C case temperature?
The STPS20150CFP is rated for 10 A average forward current per diode at TC = 135 °C, as confirmed in Table 1 of DS2252 Rev 12. This value assumes δ = 0.5 square-wave conduction and proper heatsinking to maintain case temperature at or below 135 °C. Exceeding this limit risks thermal runaway due to the device's positive temperature coefficient of VF.
Does STPS20150CFP require an insulating pad when mounted to a grounded heatsink?
No - the TO-220FPAB package provides 2000 VRMS isolation between the internal die and the metal tab, allowing direct mechanical mounting to a grounded heatsink without thermal interface pads or mica insulators. This is verified in Section 2.4 of the datasheet and eliminates risk of insulation breakdown under normal operating conditions.
How does the avalanche rating of STPS20150CFP compare to standard Schottky rectifiers?
STPS20150CFP specifies 480 W repetitive peak avalanche power at tp = 10 µs and Tj = 125 °C - a feature absent in most Schottky rectifiers. This enables reliable clamping of MOSFET turn-off voltage spikes in hard-switched topologies, unlike conventional Schottkys that fail catastrophically under similar overvoltage stress.
Can STPS20150CFP be used in place of STPS20150CT in existing designs?
Yes, but with thermal and layout considerations: STPS20150CFP (TO-220FPAB) has higher Rth(j-c) = 4.5 °C/W vs. STPS20150CT's 2.2 °C/W (TO-220AB), requiring ~2.3× larger heatsink area for equivalent temperature rise. The insulated tab also eliminates need for isolation hardware, simplifying assembly but demanding verification of creepage distances in PCB layout.
