Product details
Overview
STPS3030CG-TR from STMicroelectronics is a dual low-drop Schottky rectifier in D2PAK (TO-263) package, rated for 30 V repetitive peak reverse voltage and 2 × 15 A average forward current per diode at Tc = 135 °C, with typical forward voltage drop of 0.44 V at 15 A and 25 °C - optimized for high-efficiency, high-frequency DC/DC converters and switch-mode power supplies.
For engineers reviewing the STPS3030CG-TR datasheet, STPS3030CG-TR pinout, STPS3030CG-TR application, or STPS3030CG-TR equivalent, key selection criteria include conduction loss modeling (P = 0.26 × IF(AV) + 0.0107 × IF²(RMS)), thermal resistance (Rth(j–c) = 1.2 °C/W per diode), avalanche capability (4100 W at tp = 1 µs), and D2PAK mounting torque (0.55 Nm recommended).
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode junctions in a single D2PAK thermally enhanced surface-mount package, enabling shared heatsinking while maintaining electrical isolation between channels. Its negligible switching losses and extremely fast recovery eliminate snubber requirements in high-frequency topologies up to several hundred kHz.
The device features specified avalanche capability (PARM = 4100 W, tp = 1 µs), low thermal resistance (Rth(j–c) = 1.2 °C/W per diode), and stable reverse leakage (<1 mA at VR = 30 V, Tj = 125 °C), supporting robust operation in free-wheeling, polarity protection, and low-voltage DC inverters where thermal management and reliability under transient overload are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum repetitive reverse blocking voltage per diode; defines safe operating range in buck, flyback, or synchronous rectification circuits |
| IF(AV) per diode | 15 A at Tc = 135 °C - continuous DC current handling per channel with adequate heatsinking |
| VF(max) | 0.49 V at IF = 15 A, Tj = 25 °C - directly determines conduction loss and system efficiency at nominal load |
| Rth(j–c) | 1.2 °C/W per diode - enables thermal design using case temperature as proxy for junction temperature |
| IFSM | 250 A (tp = 10 ms, sinusoidal) - supports short-term surge tolerance during startup or fault conditions |
| PARM | 4100 W at tp = 1 µs - quantifies single-pulse avalanche energy handling for transient overvoltage robustness |
| dV/dt | 10,000 V/µs - ensures stable operation without spurious turn-on in fast-switching converter nodes |
Pinout & Package
STPS3030CG-TR uses a 3-pin D2PAK (TO-263) package with exposed metal tab serving as common cathode connection. The package provides low thermal resistance and is designed for surface-mount reflow assembly with mechanical anchoring via screw or clamp (recommended torque: 0.55 Nm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first Schottky diode | Input node for first channel; requires PCB trace sizing for 15 A continuous current |
| Pin 2 (Anode 2) | Anode of second Schottky diode | Independent input node for second channel; electrically isolated from Pin 1 |
| Tab (Cathode) | Common cathode for both diodes | Thermally and electrically connected to PCB copper pour; must be soldered for thermal performance and circuit return path |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF = 0.44 V typ. @ 15 A, 25 °C - reduces conduction loss by ~25% vs. comparable 45 V Schottkys |
| Dual-diode integration | Two independent 15 A Schottky junctions in one D2PAK - saves board space and simplifies layout in dual-rail or interleaved converters |
| Avalanche-rated operation | 4100 W single-pulse avalanche power - eliminates need for external clamping in inductive switching applications |
| Thermal resistance | Rth(j–c) = 1.2 °C/W per diode - allows direct junction temperature estimation from measured case temperature |
| ECOPACK® compliance | Lead-free second-level interconnect, JEDEC JESD97 marked - meets RoHS and industrial environmental requirements |
Applications
| Server VRM Output Rectification | Industrial DC/DC Converter Secondary Side |
|---|---|
Use Scenario: High-current, low-voltage output stage of multiphase buck converters supplying CPU/GPU core power in 1U servers. IC Role / Device Role / Timing Role: Dual-channel synchronous rectifier replacement; each anode handles one phase's output current, cathode tied to common output rail. Use Value: 0.44 V VF minimizes I²R loss at 15 A/channel, improving full-load efficiency by ≥1.2% versus 0.55 V alternatives; D2PAK thermal interface sustains 135 °C case temperature. | Use Scenario: Isolated 12 V → 3.3 V/5 V DC/DC module in programmable logic controller (PLC) power supply. IC Role / Device Role / Timing Role: Secondary-side dual-output rectifier feeding independent 3.3 V and 5 V LDO pre-regulators. Use Value: Independent anodes enable separate filtering per rail; 250 A IFSM withstands transformer reset spikes without derating; Rth(j–c) = 1.2 °C/W supports convection-cooled design. |
| Telecom AC/DC Front-End Clamp | Automotive Body Control Module Polarity Protection |
Use Scenario: Input-stage reverse-polarity and surge clamp in 48 V telecom rectifier modules subjected to lightning-induced transients. IC Role / Device Role / Timing Role: Low-VF freewheeling path during MOSFET dead-time and avalanche energy sink during line surges. Use Value: 4100 W PARM rating absorbs 1 µs 100 V/100 A transients without failure; dV/dt = 10,000 V/µs prevents false triggering during fast ESD events. | Use Scenario: Reverse-battery protection at 12 V input of BCM controlling door locks, lighting, and sensors. IC Role / Device Role / Timing Role: Cathode-connected to battery+, anodes to downstream loads - blocks reverse current while conducting forward at <0.49 V drop. Use Value: 0.49 V max VF at 15 A limits power dissipation to <7.4 W during cranking; Tj(max) = 150 °C ensures operation at under-hood ambient up to 105 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPQ030 | Same VRRM (30 V), higher IF(AV) = 30 A per diode, VF = 0.47 V @ 15 A, Rth(j–c) = 1.0 °C/W | Better thermal performance but larger TO-247 package; requires different footprint and mounting | Select when higher current headroom or lower thermal resistance is prioritized over D2PAK compatibility |
| ON Semiconductor MBR3030CT | Same TO-220AB/D2PAK variants, VF = 0.55 V @ 15 A, Rth(j–c) = 1.5 °C/W, no avalanche rating | Lacks specified avalanche capability; less efficient conduction; higher thermal resistance | Acceptable only in cost-sensitive, non-safety-critical applications where surge immunity is externally managed |
Compared with VS-30CPQ030 and MBR3030CT, STPS3030CG-TR delivers superior balance of low VF (0.44 V), verified avalanche robustness (4100 W), and D2PAK mountability - making it optimal for space-constrained, high-reliability DC/DC and industrial power designs where thermal and transient margins are tightly coupled.

FAQ
What is the maximum junction temperature and how is it enforced?
The absolute maximum junction temperature (Tj) for STPS3030CG-TR is 150 °C, validated under thermal runaway avoidance conditions with proper heatsinking. This limit is enforced by design through low Rth(j–c) = 1.2 °C/W per diode and is confirmed in the datasheet's absolute ratings table (Tj max = 150 °C). Operation beyond this temperature risks irreversible degradation of Schottky barrier integrity.
Can STPS3030CG-TR be used in parallel configurations?
STPS3030CG-TR is not recommended for parallel operation due to inherent forward voltage mismatch between diodes, which causes current imbalance and potential thermal runaway. Each device contains two matched diodes internally, but inter-device matching is not guaranteed. For higher current, use a single higher-rated part such as STPS6030CG or implement external current-sharing resistors with derating.
Is the D2PAK tab electrically isolated from the anodes?
No - the metal tab is the common cathode terminal, electrically connected to both internal Schottky cathodes. It is not isolated and must be treated as a live circuit node tied to the output rail. PCB layout must ensure the tab is soldered to a dedicated cathode copper pour, with no unintended shorts to adjacent traces or ground planes.
Does STPS3030CG-TR require a minimum load or snubber network?
No minimum load is required. Due to its Schottky construction, it exhibits negligible reverse recovery charge (Qrr ≈ 0) and does not generate switching spikes - eliminating the need for snubber networks in typical DC/DC applications. However, a small RC snubber may still be used at the anode nodes if EMI exceeds regulatory limits at very high switching frequencies (>500 kHz).
