Product details
Overview
STPS30L30CG-TR from STMicroelectronics is a dual center-tap low-drop Schottky rectifier in D2PAK package, rated for 2 × 15 A average forward current per diode, 30 V repetitive peak reverse voltage, and 150 °C maximum junction temperature. It delivers typ. 0.37 V forward voltage at 15 A/125 °C and features avalanche capability up to 45 V with 5300 W peak power, optimized for high-frequency DC–DC converters and SMPS secondary-side rectification.
For engineers reviewing the STPS30L30CG-TR datasheet, STPS30L30CG-TR pinout, STPS30L30CG-TR application, or STPS30L30CG-TR equivalent, key selection criteria include dual-diode thermal coupling behavior, low Rth(j-c) (0.8 °C/W total), conduction loss modeling (P = 0.24×IF(AV) + 0.009×IF(RMS)²), and avalanche-safe operation under <1 µs transients.
Technical Context
This dual-center-tap Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (K), enabling synchronous or interleaved low-voltage output rectification. Its extremely fast switching and negligible reverse recovery charge eliminate snubber requirements in >100 kHz topologies.
The device operates with low thermal resistance (Rth(j-c) = 0.8 °C/W total) and supports avalanche energy validation per AN1768/AN2025. Junction-to-case derating accounts for mutual heating: ΔTj(diode1) = Pdiode1 × 1.5 + Pdiode2 × 0.1 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback/freewheeling clamp circuits. |
| IF(AV) | 2 × 15 A - Average forward current rating per diode at Tc = 140 °C; enables 30 A total DC output in dual-phase configurations. |
| VF(typ) | 0.37 V @ 15 A, 125 °C - Low conduction loss reduces heat generation and improves efficiency in 3.3–12 V output rails. |
| Rth(j-c) | 0.8 °C/W (total) - Combined junction-to-case thermal resistance for both diodes; enables compact heatsink design with ≤20 W dissipation. |
| VARM | 45 V @ tp < 1 µs - Maximum repetitive avalanche voltage; allows robust handling of inductive turn-off spikes without external clamping. |
| dV/dt | 10,000 V/µs - Critical rate of rise of reverse voltage; ensures stable operation during fast-switching MOSFET transitions. |

FAQ
What is the thermal coupling behavior between the two diodes in STPS30L30CG-TR?
The two diodes share a common die substrate and thermal path. Per Table 3, junction-to-case resistance is 1.5 °C/W per diode, with 0.1 °C/W coupling resistance between them. So heating in one diode raises the other's junction temperature by ΔT = P₂ × 0.1 °C/W - critical for parallel-phase thermal design.
Can STPS30L30CG-TR replace TO-220AB-packaged STPS30L30CT in the same PCB layout?
No - D2PAK (STPS30L30CG-TR) and TO-220AB (STPS30L30CT) have incompatible footprints and mounting methods. D2PAK requires surface-mount reflow with thermal pad soldering; TO-220AB uses through-hole leads and mechanical screw mounting. Layout redesign is mandatory.
How is avalanche capability validated for this part?
Avalanche energy rating is validated per ST application notes AN1768 and AN2025 using unclamped inductive switching (UIS) tests. VARM = 45 V and PARM = 5300 W are measured at tp < 1 µs, Tj < 150 °C, and IAR < 35 A, with SOA defined in Figure 12 of the datasheet.
What is the maximum continuous power dissipation per diode at 100 °C case temperature?
From Figure 2: at Tc = 100 °C and δ = 0.5, average forward power dissipation is ~5.2 W per diode. Using P = 0.24×IF(AV) + 0.009×IF(RMS)², this corresponds to ~13.5 A average current per diode under those thermal conditions.
