Product details
Overview
STPS30L60CG-TR from STMicroelectronics is a dual-center-tap Schottky rectifier in D2PAK package, rated for 60 V repetitive peak reverse voltage and 30 A total average forward current (15 A per diode), with maximum forward voltage of 0.56 V at 15 A and 125 °C junction temperature. It delivers low conduction loss and negligible switching losses for high-frequency DC–DC converters and switched-mode power supplies.
For engineers reviewing the STPS30L60CG-TR datasheet, STPS30L60CG-TR pinout, STPS30L60CG-TR application, or STPS30L60CG-TR equivalent, key selection criteria include its 1.5 °C/W junction-to-case thermal resistance (per diode), avalanche-rated 80 V peak voltage, 230 A non-repetitive surge capability, and suitability for thermally constrained high-efficiency power stages.
Technical Context
This dual-diode Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap configuration), enabling synchronous rectification in half-bridge or full-wave topologies. Its low dV/dt rating of 10,000 V/µs supports fast-switching operation without spurious turn-on.
The device features specified avalanche capability (7800 W peak, 80 V, 1 µs pulse) and is characterized across −65 to +175 °C storage range and up to 150 °C maximum operating junction temperature, with thermal derating defined for δ = 0.5 duty cycle at Tc = 130 °C (TO-220AB/D2PAK/I2PAK/TO-247 variants).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or LLC resonant converter secondary side. |
| IF(AV) per diode | 15 A - Average forward current rating per diode at Tc = 130 °C, δ = 0.5; determines continuous output current capability in center-tap transformer designs. |
| VF (max) | 0.56 V at 15 A, 125 °C - Peak forward voltage drop; directly sets conduction loss (P ≈ 0.42×IF(AV) + 0.009×IF(RMS)²) in high-efficiency SMPS. |
| Rth(j-c) per diode | 1.5 °C/W - Junction-to-case thermal resistance (D2PAK); enables precise heatsink sizing for thermal management under 30 A total load. |
| IFSM | 230 A - Non-repetitive surge current (10 ms, sinusoidal); supports inrush and transient overload tolerance in industrial power supplies. |
| VARM | 80 V - Maximum repetitive avalanche voltage (tp < 1 µs); allows controlled energy absorption during inductive switching events without failure. |
| Tj(max) | 150 °C - Maximum junction temperature; sets upper thermal boundary for reliability modeling and derating curves in continuous operation. |
Pinout & Package
STPS30L60CG-TR is housed in a surface-mount D2PAK (TO-263AB) package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features a copper-exposed thermal pad on the underside for direct PCB thermal coupling and meets UL94 V0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | First Schottky diode anode; connects to primary-side switch node in center-tap forward converter or leg 1 of half-bridge secondary. |
| A2 | Anode 2 | Second Schottky diode anode; connects to complementary switch node, enabling dual-path rectification with shared cathode return. |
| K | Common Cathode | Single low-impedance output node; serves as DC output rail connection point, minimizing layout parasitics in high-current paths. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.56 V max at 15 A/125 °C reduces conduction loss by >30% vs. standard silicon rectifiers in 12–48 V output rails. |
| Negligible switching losses | Zero minority-carrier storage enables hard-switching at >500 kHz without reverse recovery tail, eliminating snubber requirements. |
| Avalanche capability | Rated for 7800 W peak avalanche power (80 V, 1 µs) - permits robust operation during voltage transients in unregulated or loosely coupled transformers. |
| Low thermal resistance | 1.5 °C/W j-c (per diode) in D2PAK allows ≥25 W dissipation with ≤40 °C temperature rise above case, supporting compact heatsinking. |
| Center-tap dual-diode topology | Integrated A1–K and A2–K paths simplify PCB layout for push-pull, forward, and full-wave center-tap converters versus discrete dual-diode solutions. |
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-30CPH06-M3 | D2PAK package, same 60 V VRRM, but 0.62 V VF max at 15 A/125 °C and 2.0 °C/W Rth(j-c). | Higher conduction loss and thermal resistance reduce efficiency by ~1.2% and require larger heatsink area in space-constrained designs. | Select when legacy qualification or Vishay supply chain alignment is required; verify thermal margin with revised Rth and VF. |
| ON Semiconductor MBR3060CT | TO-220AB package (not surface-mount), identical 60 V/30 A rating, but 0.72 V VF max and no specified avalanche rating. | Through-hole mounting increases assembly cost and limits high-density PCB layouts; absence of avalanche spec restricts use in unclamped inductive circuits. | Prefer only for through-hole legacy systems where D2PAK rework is prohibited; avoid in new designs requiring surge robustness or SMT scalability. |
Compared with VS-30CPH06-M3 and MBR3060CT, STPS30L60CG-TR offers the lowest VF and best thermal performance in D2PAK, making it optimal for high-efficiency, surface-mount power supplies where board space and thermal headroom are critical constraints.

FAQ
What is the thermal pad soldering requirement for STPS30L60CG-TR in D2PAK?
The D2PAK package features an exposed thermal pad on the underside that must be soldered to a minimum 2 cm² copper area on the PCB using a grid pattern of ≥9 thermal vias (0.3 mm diameter, filled or capped) to achieve the specified 1.5 °C/W junction-to-case resistance. Insufficient thermal pad connection raises junction temperature by up to 25 °C at full load.
Does STPS30L60CG-TR support parallel operation of both diodes in a single-output configuration?
Yes - the dual-center-tap structure allows simultaneous conduction of both diodes into the common cathode (K) terminal, enabling 30 A total average current delivery in full-wave center-tap topologies. Thermal derating must account for combined power dissipation (Ptot = Pdiode1 + Pdiode2) and shared case temperature rise.
How does the avalanche rating of STPS30L60CG-TR impact system-level protection design?
The 80 V VARM and 7800 W PARM ratings allow the device to safely absorb inductive energy during MOSFET turn-off without external clamping, provided the avalanche energy E = ∫V×I dt remains within the curve in Figure 12. This eliminates need for TVS diodes in well-designed transformer-coupled topologies, reducing component count and cost.
Can STPS30L60CG-TR replace TO-220AB variants like STPS30L60CT in existing designs?
No - STPS30L60CG-TR uses D2PAK (surface-mount) packaging versus TO-220AB (through-hole), requiring PCB footprint, stencil, and reflow profile changes. While electrically identical, mechanical incompatibility prevents drop-in replacement; thermal performance differs due to distinct Rth(j-c) paths and mounting methods.
