Product details
Overview
STPS30L30DJF-TR from STMicroelectronics is a 30 V, 30 A low-profile PowerFLAT 5x6 Schottky rectifier optimized for high-frequency DC/DC converters and SMPS secondary-side rectification. It delivers typ. 0.30 V forward voltage at 30 A and 125 °C, with 2 °C/W junction-to-case thermal resistance and avalanche rating up to 500 W (10 µs pulse), enabling compact, high-efficiency telecom power supplies.
For engineers reviewing the STPS30L30DJF-TR datasheet, STPS30L30DJF-TR pinout, STPS30L30DJF-TR application, or STPS30L30DJF-TR equivalent, key selection criteria include its 30 V reverse voltage rating, 30 A average forward current capability, 1 mm thin profile, low conduction loss equation (P = 0.27×IF(AV) + 0.006×IF²(RMS)), and PowerFLAT 5x6 thermal performance under constrained PCB space.
Technical Context
This device operates as a unidirectional, low-loss freewheeling and polarity protection diode in synchronous and non-synchronous buck/boost topologies. Its Schottky barrier construction eliminates minority-carrier storage delay, enabling negligible switching losses and extremely fast recovery (<10 ns typical reverse recovery time implied by zero Qrr and fast switching claim).
The PowerFLAT 5x6 package integrates a thermally enhanced copper-exposed die pad directly bonded to PCB copper, achieving Rth(j-c) = 2 °C/W and supporting high-current operation without external heatsink when mounted on ≥120 cm² of 70 µm Cu. Avalanche rating confirms robustness against inductive load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24 V bus DC/DC outputs. |
| IF(AV) | 30 A - Average forward current at Tc = 110 °C; supports continuous 30 A output in telecom PSUs with proper PCB copper area. |
| VF (typ.) | 0.30 V @ 30 A, 125 °C - Low conduction loss enables >95% efficiency in 5–12 V output stages. |
| Rth(j-c) | 2 °C/W - Junction-to-case thermal resistance; allows direct thermal path to PCB, eliminating need for bolted heatsinks. |
| IFS M | 250 A @ 10 ms - Non-repetitive surge rating; withstands startup inrush and short-circuit events in server power rails. |
| Tj (max.) | +150 °C - Maximum junction temperature; enables operation in sealed industrial enclosures without forced air. |
Pinout & Package
Package: PowerFLAT 5x6 (5.0 × 6.0 × 1.0 mm), surface-mount, thermally enhanced with exposed copper die pad (cathode-connected). Compliant with ECOPACK2 environmental standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input current terminal | Connected to switching node (e.g., MOSFET drain); carries full load current during freewheeling phase. |
| Cathode (K) | Output current terminal | Connected to output rail; electrically tied to exposed copper pad for thermal and electrical return path. |
| Exposed Pad | Thermal & electrical cathode extension | Must be soldered to ≥120 cm² PCB copper pour; provides primary heat dissipation path and reduces Rth(j-a) to ~7 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high temperature | 0.30 V typ. @ 30 A, 125 °C - Reduces conduction loss by >40% vs. silicon diodes in hot environments. |
| Thin 1 mm profile | Height ≤1.0 mm - Enables use in ultra-low-profile telecom modules (e.g., 1U servers, PoE injectors) where Z-height is constrained. |
| Avalanche rated | 500 W peak (10 µs) - Withstands voltage spikes from transformer leakage inductance without failure. |
| PowerFLAT thermal design | Rth(j-c) = 2 °C/W - Delivers 30 A continuous current with <20 °C junction rise above case when PCB copper is properly sized. |

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-30CPQ030 | Same 30 V/30 A rating but TO-220AC package; Rth(j-c) = 2.5 °C/W; VF = 0.42 V @ 30 A, 25 °C. | Requires heatsink mounting; unsuitable for ultra-thin designs; higher conduction loss at elevated temperature. | Choose for legacy through-hole assembly or where mechanical robustness outweighs Z-height constraints. |
| ON Semiconductor SB330 | DO-201AD package; 30 V/3.0 A rating; VF = 0.52 V @ 3 A; not rated for avalanche or high RMS current. | Limited to low-power auxiliary rails; cannot replace STPS30L30DJF-TR in 30 A main output paths. | Only suitable for cost-sensitive, low-current (<5 A) applications where thermal performance is secondary. |
Compared with VS-30CPQ030 and SB330, STPS30L30DJF-TR uniquely combines 30 A current handling, 1 mm profile, 2 °C/W thermal resistance, and 500 W avalanche capability-making it the only viable option for space-constrained, high-reliability 48 V telecom and server DC/DC systems.

FAQ
What is the maximum allowable PCB copper area required for full 30 A operation?
Per Figure 8 in DS8955, a minimum of 120 cm² of 70 µm thick copper on the component side is required to achieve Rth(j-a) ≈ 7 °C/W and sustain 30 A average current at Tamb = 70 °C. Smaller copper areas reduce derated current capacity proportionally.
Is the exposed thermal pad electrically isolated or connected to a specific terminal?
The exposed copper pad is electrically connected to the cathode (K) terminal. It must be soldered to a PCB copper pour tied to the cathode net and cannot be left floating or grounded independently without violating the device's electrical and thermal specifications.
Does STPS30L30DJF-TR have a specified reverse recovery time (trr)?
No trr is specified because this is a majority-carrier Schottky diode with no minority-carrier storage charge. Its switching behavior is governed solely by junction capacitance (Cj ≈ 1000 pF at 0 V, per Figure 6), resulting in effectively zero reverse recovery loss-critical for >500 kHz DC/DC operation.
Can STPS30L30DJF-TR be used in parallel configurations for higher current?
Parallel operation is not recommended due to mismatch in VF temperature coefficients and thermal coupling limitations. ST does not characterize or guarantee balanced current sharing. For >30 A, select a single higher-rated device (e.g., STPS40L30CW) or redesign with multiple independent phases.
