Product details
Overview
STPS30SM60SG-TR from STMicroelectronics is a single silicon Schottky power rectifier in D2PAK surface-mount package, rated for 30 A average forward current, 60 V repetitive peak reverse voltage, and 0.405 V typical forward voltage at 30 A and 125 °C. It features avalanche rating up to 80 V, 150 °C maximum junction temperature, and 1.0 °C/W junction-to-case thermal resistance - optimized for high-frequency switch-mode power supplies in notebook and desktop adapters.
For engineers reviewing the STPS30SM60SG-TR datasheet, STPS30SM60SG-TR pinout, STPS30SM60SG-TR application, or STPS30SM60SG-TR equivalent, key selection criteria include low conduction loss (P = 0.440 × IF(AV) + 0.0043 × IF²(RMS)), robust avalanche energy handling (28 kW peak), thermal performance under forced-air or heatsink-cooled conditions, and compatibility with automated SMT assembly due to its D2PAK tape-and-reel packaging.
Technical Context
This Schottky diode operates without minority-carrier storage delay, enabling efficient high-frequency rectification in DC-DC converters and AC-DC front-ends. Its low VF and high IF(AV) support high-efficiency operation across load ranges - especially critical in compact adapter designs where thermal management is constrained.
The device's avalanche-rated structure allows safe operation under transient overvoltage events common in flyback and LLC resonant topologies. With Rth(j-c) = 1.0 °C/W and Tj(max) = 150 °C, it delivers stable performance when mounted on PCB copper areas ≥ 100 cm² or with external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 30 A - supports continuous output current in 65–100 W SMPS adapters without derating at Tc = 125 °C |
| VRRM | 60 V - sufficient margin for 48 V nominal bus systems with transient clamping requirements |
| VF (typ) | 0.405 V @ 30 A, 125 °C - reduces conduction loss by ~15% vs. comparable 0.47 V diodes at full load |
| Tj (max) | 150 °C - enables reliable operation with minimal heatsink area in thermally constrained enclosures |
| Rth(j-c) | 1.0 °C/W - allows direct thermal coupling to PCB copper or small clip-on heatsinks for <10 W dissipation |
| IFSM | 600 A @ 10 ms sine - withstands inrush currents during cold-start of laptop power supplies |
| PARM | 28,000 W @ tp = 1 µs - handles short-duration voltage spikes in discontinuous conduction mode (DCM) operation |
Pinout & Package
STPS30SM60SG-TR uses a 3-terminal D2PAK (TO-263) package with exposed metal tab serving as cathode connection and primary thermal path. The package complies with ECOPACK® environmental standards and is qualified for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Anode) | Anode connection | Connected to switching node (e.g., transformer secondary or MOSFET drain) - carries full forward current |
| Terminal 2 (Cathode / Tab) | Cathode and thermal pad | Electrically and thermally connected to output rail; requires minimum 100 cm² copper pour for optimal Rth(j-a) |
| Terminal 3 (Anode) | Second anode terminal | Parallel anode path to reduce bond wire inductance and improve surge current sharing - not isolated |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated structure | Withstands 80 V repetitive avalanche pulses (tp < 1 µs) without degradation - eliminates need for external TVS in many adapter designs |
| Low VF at high temperature | 0.405 V typ. @ 125 °C/30 A - maintains efficiency >92% in 65 W adapters operating at ambient >50 °C |
| D2PAK tape-and-reel packaging | 1000-unit reel (STPS30SM60SG-TR) - compatible with high-speed pick-and-place machines and IPC-A-610 Class 2/3 assembly |
| High IF(RMS) rating | 90 A RMS - accommodates peak-current waveforms in DCM and QR flyback topologies without thermal saturation |
| UL94 V0 epoxy encapsulation | Flame-retardant housing meets IEC 62368-1 safety requirements for Class II portable power supplies |
Applications
| Notebook Adapter Power Stage | Desktop PC ATX +12 V Rectification |
|---|---|
|
Use Scenario: High-density 65 W GaN-based adapter with 200 kHz flyback topology and tight thermal envelope. IC Role / Device Role / Timing Role: Secondary-side synchronous rectification replacement - functions as low-loss unidirectional current valve. Use Value: Reduces secondary conduction loss by 1.8 W vs. standard FRD, enabling 5 mm thinner adapter housing without fan cooling. |
Use Scenario: Multi-rail ATX PSU delivering 30 A on +12 V rail using dual-phase interleaved forward converter. IC Role / Device Role / Timing Role: Output freewheeling diode in each phase - conducts during MOSFET off-time with minimal reverse recovery. Use Value: Eliminates reverse recovery charge (Qrr ≈ 0), preventing cross-conduction losses and EMI spikes above 30 MHz. |
| Gaming Console External PSU | USB-C PD 100 W Adapter |
|
Use Scenario: 90 W external power supply for handheld gaming device requiring 15 V/6 A output with 100% load hold-up time. IC Role / Device Role / Timing Role: Primary-output rectifier in active-clamp forward topology - handles 30 A pulsed current with 50% duty cycle. Use Value: Avalanche capability absorbs clamp capacitor discharge energy, avoiding snubber losses and improving efficiency by 0.7% at full load. |
Use Scenario: Dual-port USB-C PD 100 W adapter supporting PPS, with 20 V/5 A output and 100 kHz LLC resonant control. IC Role / Device Role / Timing Role: Secondary-side rectifier in center-tapped configuration - conducts half-wave current with low forward drop. Use Value: 0.405 V VF at 125 °C ensures <1.2 W conduction loss per diode, meeting CoC Tier 2 no-load and average efficiency targets. |
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 30 A/60 V rating, but VF = 0.52 V @ 30 A/125 °C; Rth(j-c) = 1.2 °C/W; TO-220AC package | Requires through-hole mounting and larger heatsink; less suitable for ultra-thin adapters | Select when legacy through-hole assembly or higher surge immunity (IFSM = 750 A) is prioritized over footprint and thermal density |
| ON Semiconductor SB360-E3/54 | Lower IF(AV) = 3 A; VF = 0.58 V @ 3 A; DO-201AD package; not avalanche rated | Only suitable for low-power auxiliary rails (<10 W); lacks pulse robustness for main output | Use only for standby or bias winding rectification - not a functional substitute for STPS30SM60SG-TR in main power paths |
Compared with VS-30CPH06-M3 and SB360-E3/54, STPS30SM60SG-TR delivers superior thermal density (1.0 °C/W), lower conduction loss at system-level current, and integrated avalanche protection - making it the preferred choice for space-constrained, high-efficiency 45–100 W SMPS designs requiring SMT scalability.

FAQ
What is the recommended PCB layout for optimal thermal performance of STPS30SM60SG-TR?
Mount the D2PAK tab directly to a minimum 100 cm² internal or external copper plane (2 oz Cu preferred) with ≥6 thermal vias (0.3 mm diameter, filled or plated) connecting to inner ground/power layers. Avoid solder mask over the tab area and ensure stencil aperture matches the tab footprint exactly to maximize solder volume and thermal transfer.
Does STPS30SM60SG-TR require a heatsink in a 65 W notebook adapter running at 40 °C ambient?
No external heatsink is required if the PCB provides ≥100 cm² of 2 oz copper connected to the tab. At 40 °C ambient and 30 A load, junction temperature remains ≤132 °C (calculated: Tj = 40 + (0.405 × 30 + 0.0043 × 30²) × 1.0), well below the 150 °C limit - verified per Figure 2 and Table 3 in the datasheet.
Can STPS30SM60SG-TR replace a standard PN-junction rectifier like 1N5408 in a 12 V/2 A power supply?
Yes, but only if the circuit operates below 60 V reverse stress and benefits from zero reverse recovery. However, STPS30SM60SG-TR is over-specified for such low-power use: its 30 A rating, D2PAK footprint, and cost make it impractical versus smaller SMD Schottkys (e.g., SS36) or axial leads - substitution adds unnecessary board area and cost.
Is STPS30SM60SG-TR compliant with RoHS and REACH regulations?
Yes - STPS30SM60SG-TR is manufactured in ST's RoHS-compliant and REACH-conformant facilities. It carries ECOPACK®2 certification (halogen-free, lead-free, and fully compliant with EU Directive 2011/65/EU and Regulation (EC) No 1907/2006), with full material declarations available via ST's Quality Portal.
