Product details
Overview
STPS30M60SG-TR from STMicroelectronics is a single high-current Schottky rectifier diode in D2PAK surface-mount package, rated for 30 A average forward current, 60 V repetitive peak reverse voltage, and 0.380 V typical forward voltage at 125 °C/30 A. It features avalanche rating (80 V max repetitive peak), 0.9 °C/W junction-to-case thermal resistance, and is optimized for high-frequency SMPS in notebook and desktop adapters.
For engineers reviewing the STPS30M60SG-TR datasheet, STPS30M60SG-TR pinout, STPS30M60SG-TR application, or STPS30M60SG-TR equivalent, key selection criteria include low conduction loss (P = 0.395×IF(AV) + 0.0047×IF²(RMS)), thermal performance under Tc = 130 °C, and avalanche energy handling per AN1768/AN2025 validation.
Technical Context
This Schottky diode operates without minority-carrier storage, enabling zero reverse recovery time and minimal switching loss in high-frequency DC-DC converters. Its low VF (0.380–0.535 V across temperature/load) directly reduces conduction losses in secondary-side rectification stages.
The device is avalanche-rated with VARM = 80 V (tp < 1 µs, Tj < 150 °C, IAR < 129 A) and PARM = 34.4 kW, validated per ST application notes AN1768 and AN2025. Thermal design relies on Rth(j-c) = 0.9 °C/W and requires heatsinking via the exposed tab to maintain Tj ≤ 150 °C at IF(AV) = 30 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 30 A - maximum continuous forward current at Tc = 130 °C, defining usable output power in adapter designs |
| VRRM | 60 V - peak reverse blocking capability, suitable for 48 V input or 5 V/12 V/19 V output rails |
| VF (typ) | 0.380 V at 30 A, 125 °C - enables <0.5 W conduction loss at full load, critical for efficiency compliance |
| Tj (max) | 150 °C - absolute junction limit; derating required above ambient due to Rth(j-c) = 0.9 °C/W |
| Rth(j-c) | 0.9 °C/W - quantifies thermal path from die to case; mandates direct metal heatsink contact under tab |
| IFSM | 600 A (10 ms sine) - surge rating supports inrush and transient overload without failure |
| VARM | 80 V (tp < 1 µs) - defines safe reverse avalanche energy window during switching transients |
Pinout & Package
STPS30M60SG-TR uses a 3-terminal D2PAK (TO-263) package with an electrically active exposed metal tab serving as the cathode terminal. The package is RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Anode) | Anode connection | Input side of rectifier; connects to transformer secondary or switch node |
| Terminal 2 (Cathode) | Cathode connection | Output side of rectifier; ties to output capacitor and load ground reference |
| Tab (Cathode) | Electrically connected cathode | Primary thermal path and electrical return; must be soldered to copper pour for thermal and EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Validated 80 V repetitive peak avalanche voltage per AN1768, enabling robustness against inductive switching spikes |
| Low forward voltage drop | 0.380 V typ. at 30 A/125 °C reduces conduction loss by >25% vs. standard silicon diodes in same footprint |
| High-frequency suitability | No reverse recovery charge (Qrr = 0) eliminates switching loss and EMI in >100 kHz SMPS topologies |
| Thermally optimized package | D2PAK's 0.9 °C/W Rth(j-c) supports 30 A continuous operation with minimal PCB copper area (≥40 cm² recommended) |
| ECOPACK® environmental compliance | Meets UL94 V0 flammability and RoHS requirements without lead-free solder compatibility compromises |
Applications
| Adapter Secondary Rectification | Laptop Power Supply Output Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH06-M3 | Same 60 V VRRM, 30 A IF(AV), but TO-220AC package; Rth(j-c) = 1.2 °C/W; VF = 0.49 V @ 30 A/125 °C | Requires through-hole assembly and larger heatsink; less suitable for ultra-thin adapters | Select when legacy through-hole layout or higher surge margin (IFSM = 750 A) is prioritized over thermal density |
| ON Semiconductor MBR3060CT | Dual-diode configuration in TO-220AB; each anode-cathode pair rated 30 A/60 V; VF = 0.62 V @ 30 A/25 °C | Not pin-compatible; dual-channel topology adds routing complexity and increases conduction loss | Choose only if dual-output flyback or redundancy architecture demands two independent 30 A paths in one package |
Compared with VS-30CPH06-M3 and MBR3060CT, STPS30M60SG-TR delivers superior thermal density (0.9 °C/W), lowest VF at elevated temperature, and surface-mount scalability-making it optimal for space-constrained, high-efficiency adapter designs where thermal management and board real estate are critical.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies IF(AV) = 30 A at Tc = 130 °C. Exceeding this temperature requires linear derating per Figure 3; at Tc = 140 °C, maximum IF(AV) drops to ~26 A. Maintaining Tc ≤ 130 °C requires ≥40 cm² of 2 oz copper connected to the D2PAK tab with thermal vias.
Is STPS30M60SG-TR suitable for synchronous rectification replacement?
No-it is a passive Schottky diode, not a synchronous rectifier IC. It replaces standard PN diodes in secondary-side rectification but lacks gate drive, sensing, or control logic. For true synchronous rectification, discrete MOSFETs with external controllers (e.g., STSR3) or integrated SR controllers are required.
Does this part require a minimum solder mask opening for the D2PAK tab?
Yes-the exposed tab must be fully soldered to a large copper pour. ST recommends a minimum solder mask opening matching the tab footprint (9.15 × 10.2 mm per Table 6), with no solder mask dams, to ensure mechanical adhesion and optimal thermal transfer to the PCB.
How is avalanche capability validated for STPS30M60SG-TR?
Avalanche robustness is validated per ST application notes AN1768 and AN2025 using controlled unclamped inductive switching (UIS) tests. The device sustains 80 V repetitive peak avalanche voltage (VARM) at tp < 1 µs and IAR < 129 A, with energy limits defined in Figure 12's reverse SOA.
