Product details
Overview
STPS30150CG-TR from STMicroelectronics is a dual-center-tap high-voltage Schottky rectifier in D²PAK (TO-263) package, rated for 150 V reverse voltage and 15 A average forward current per diode, with typical forward voltage drop of 0.69 V at 125 °C and 15 A. It is designed for high-frequency switch-mode power supplies requiring low conduction loss and high thermal reliability.
For engineers reviewing the STPS30150CG-TR datasheet, STPS30150CG-TR pinout, STPS30150CG-TR application, or STPS30150CG-TR equivalent, key selection criteria include junction-to-case thermal resistance (0.85 °C/W total), avalanche power rating (750 W), insulated package compliance (ECOPACK®2), and dual-diode center-tap configuration for synchronous rectification topologies.
Technical Context
This dual Schottky rectifier integrates two identical anode-cathode diodes sharing a common cathode terminal (center-tap configuration), enabling use in full-wave rectification and synchronous buck-derived topologies. Its low VF–IR trade-off supports high-efficiency operation at switching frequencies up to several hundred kHz.
The device features specified avalanche capability (750 W peak, 10 µs pulse), junction temperature rating up to +175 °C, and insulating package construction (D²PAK with isolated tab). Thermal performance is defined by Rth(j-c) = 0.85 °C/W (total for both diodes) and Rth(j-a) dependent on PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per diode; defines usable input voltage range in AC/DC or DC/DC stages. |
| IF(AV) per diode | 15 A - Average forward current rating per diode at TC = 120 °C; determines continuous output current capability in center-tap designs. |
| VF (typ) | 0.69 V @ 15 A, 125 °C - Low forward voltage minimizes conduction loss and improves efficiency in high-current SMPS outputs. |
| Rth(j-c) total | 0.85 °C/W - Junction-to-case thermal resistance for both diodes combined; enables accurate heatsink sizing when mounted on copper plane. |
| Tj(max) | +175 °C - Maximum junction temperature; allows operation in high-ambient industrial or automotive under-hood environments. |
| IR (max) | 8.0 mA @ 125 °C, VR = VRRM - Low leakage preserves efficiency during light-load or standby modes in regulated supplies. |
| PARM | 750 W @ tp = 10 µs - Peak avalanche power rating ensures robustness against transient overvoltage events without clamping circuitry. |
Pinout & Package
The STPS30150CG-TR uses the D²PAK (TO-263) surface-mount package with isolated tab, featuring three terminals: two anodes (A1, A2) and one shared cathode (K). The package provides 2000 VRMS insulation between tab and terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input connection for first half of center-tapped transformer secondary or first phase leg in dual-output topology. |
| A2 | Anode 2 | Input connection for second half of center-tapped transformer secondary or second phase leg. |
| K | Common Cathode | Output node for full-wave rectified DC; serves as reference for output filter capacitor and load return path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual center-tap Schottky configuration | Enables full-wave rectification with single-package integration, reducing board space vs. discrete dual-diode solutions. |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements without compromising thermal or electrical performance in industrial-grade applications. |
| Insulated D²PAK package | Provides 2000 VRMS isolation between mounting tab and terminals, eliminating need for insulating hardware in heatsink-mounted designs. |
| Avalanche-rated operation | Guaranteed 750 W peak avalanche energy handling supports reliable operation during line transients or inductive kickback events. |
Applications

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-30CPH015 | Same 150 V VRRM, 15 A IF(AV)/diode, but TO-247 package; Rth(j-c) = 1.5 °C/W per diode (worse thermal coupling). | Requires mechanical insulator and higher-torque mounting; less suitable for high-density SMT layouts. | Select when forced-air cooling is available and through-hole assembly is preferred. |
| ON Semiconductor MBR30150CT | Identical D²PAK package and pinout, but higher VF (0.82 V typ @ 125 °C) and no specified avalanche rating. | Lacks guaranteed avalanche robustness; may require external TVS in high-transient environments. | Select only for cost-sensitive, low-transient applications where 0.13 V higher VF is acceptable. |
Compared with VS-30CPH015 and MBR30150CT, STPS30150CG-TR offers superior thermal resistance (0.85 °C/W total), certified avalanche capability (750 W), and ECOPACK®2 compliance-making it optimal for thermally constrained, high-reliability SMT power supplies.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPS30150CG-TR is rated for 15 A average forward current per diode at TC = 120 °C. Exceeding this temperature requires derating per Figure 2 in the datasheet; sustained operation above 120 °C case temperature risks exceeding the 175 °C maximum junction temperature, especially under high ambient or poor PCB copper area conditions.
Is the D²PAK tab electrically isolated from the terminals?
Yes-the D²PAK package used in STPS30150CG-TR is the insulated variant (TO-220FPAB-equivalent isolation level), with 2000 VRMS dielectric strength between the metal tab and all terminals. This allows direct mounting to grounded heatsinks without insulating pads or washers.
Can STPS30150CG-TR replace a single-diode D²PAK in existing designs?
No-it is a dual-diode center-tap device with three terminals (A1, A2, K); replacing a single-diode part would require schematic and layout changes to accommodate the shared cathode topology and dual-anode inputs. Pinout and function are not interchangeable with single-diode Schottkys like STPS30H100CG.
Does this part support lead-free reflow soldering per JEDEC J-STD-020?
Yes-STPS30150CG-TR is qualified for standard lead-free reflow profiles (peak temperature ≤ 260 °C, 20–40 sec dwell), consistent with its ECOPACK®2 halogen-free and RoHS-compliant construction. The D²PAK package meets IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1).
