Product details
Overview
STTH30R02DJF-TR from STMicroelectronics is a 200 V, 30 A ultrafast recovery silicon diode in PowerFLAT 5x6 package, optimized for high-frequency DC/DC converters and telecom power supplies. It delivers low conduction loss (VF = 0.8 V typ. at 150 °C), fast reverse recovery (trr = 27 ns typ.), high surge capability (IFSM = 300 A), and operates up to 175 °C junction temperature.
For engineers reviewing the STTH30R02DJF-TR datasheet, STTH30R02DJF-TR pinout, STTH30R02DJF-TR application, or STTH30R02DJF-TR equivalent, key selection criteria include reverse recovery softness (Sfactor = 0.3), Qrr = 140 nC, thermal resistance Rth(j-c) = 2.0 °C/W, and thin 1 mm profile for space-constrained power stages.
Technical Context
This diode employs an optimized ultrafast recovery epitaxial structure with controlled carrier lifetime to minimize switching losses while maintaining soft recovery behavior-critical for reducing EMI in synchronous rectification and LLC resonant topologies. Its low VF and high Tj rating support high-efficiency, high-density designs in telecom and server SMPS.
The PowerFLAT 5x6 package enables double-sided cooling via exposed copper tab, delivering 2.0 °C/W junction-to-case thermal resistance. The device's dIF/dt-dependent trr (27–50 ns), IRM (6–8 A), and Qrr (140 nC) are characterized across 25–125 °C, supporting robust design under dynamic load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input rails up to 160 V DC in telecom rectifiers without derating |
| IF(AV) | 30 A at TC = 105 °C - enables compact heatsinking in high-current output stages |
| trr (typ.) | 27 ns at 25 °C - reduces turn-off switching loss in >300 kHz DC/DC converters |
| VF (typ.) | 0.80 V at 150 °C / 30 A - lowers conduction loss vs. standard FRDs in high-temp operation |
| Rth(j-c) | 2.0 °C/W - allows direct thermal coupling to PCB copper or heatsink for efficient power dissipation |
| Qrr | 140 nC - quantifies stored charge removed during reverse recovery, critical for snubberless layout |
| Sfactor | 0.3 - indicates soft recovery behavior, suppressing voltage overshoot and EMI generation |
Pinout & Package
STTH30R02DJF-TR uses the PowerFLAT 5x6 surface-mount package with exposed thermal pad (bottom-side cathode connection). Total height is 1.0 mm max, enabling ultra-thin power modules and VRMs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (top-side metal area) | Forward current entry point | Connected to switching node (e.g., MOSFET drain); requires low-inductance routing |
| Cathode (exposed bottom pad) | Forward current exit / thermal path | Must be soldered to ≥2 cm² of inner-layer copper for optimal Rth(j-a) and surge handling |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr = 27 ns typ. enables use in >500 kHz topologies without excessive switching loss |
| High surge current | IFSM = 300 A (10 ms sine) supports inrush and fault transients in telecom hot-swap circuits |
| High-energy avalanche rating | Rated for repetitive avalanche energy-enables rugged operation in inductive load switching |
| Thin 1 mm profile | PowerFLAT 5x6 height ≤1.0 mm allows integration into ultra-low-profile VRMs and baseplate-mounted modules |
| ECOPACK2 compliance | Halogen-free, RoHS-compliant construction meets strict environmental requirements for telecom infrastructure |
Applications
| Telecom Rectifier Module | Server VRM Output Stage |
|---|---|
Use Scenario: 48 V input, 12 V/60 A output DC/DC stage in 19-inch rack power shelf. IC Role / Device Role / Timing Role: Synchronous rectifier freewheeling diode in multiphase buck converter.

IC Role / Device Role / Timing Role: Secondary-side freewheeling diode in high-frequency interleaved buck. Use Value: 27 ns trr and 140 nC Qrr minimize dead-time loss and cross-conduction risk during phase interleaving. |
| Industrial DC/DC Converter | Optical Line Terminal (OLT) Power Supply |
Use Scenario: 24–48 V input, 5 V/20 A isolated DC/DC for PLC I/O modules. IC Role / Device Role / Timing Role: Output rectifier in forward or active clamp flyback topology. Use Value: 175 °C Tj rating ensures reliability in sealed enclosures with limited airflow. | Use Scenario: -48 V telecom line-powered supply feeding GPON optical transceivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L02DJF-TR | Lower VF (0.75 V typ. at 150 °C), same trr (27 ns), identical PowerFLAT 5x6 package | Better conduction efficiency at high ambient temp; slightly reduced softness (Sfactor ≈ 0.25) | Select when thermal margin is constrained and EMI sensitivity is moderate |
| IXYS MBR30200CT | TO-220AC package, 200 V/30 A Schottky, VF = 0.92 V, no reverse recovery (trr = 0) | No Qrr-related losses but limited to ≤125 °C Tj and higher leakage (IR = 1 mA at 125 °C) | Select for lower-noise, lower-frequency (<200 kHz) designs where junction temp stays below 125 °C |
Compared with STTH30R02DJF-TR, STTH30L02DJF-TR trades minor softness reduction for lower conduction loss, while MBR30200CT eliminates reverse recovery entirely but sacrifices thermal robustness and leakage performance in high-temp telecom environments.

FAQ
What is the maximum recommended PCB copper area for the cathode pad?
The datasheet recommends ≥2 cm² of inner-layer copper connected to the exposed cathode pad to achieve the specified Rth(j-c) = 2.0 °C/W and sustain IFSM = 300 A. Use thermal vias (≥8 × 0.3 mm) to inner ground planes for optimal heat spreading and mechanical reliability.
Does STTH30R02DJF-TR support synchronous rectification drive?
No-it is a passive ultrafast recovery diode, not a MOSFET-based synchronous rectifier. It functions as a freewheeling or output rectifier in non-controlled topologies (e.g., buck, forward, flyback). For synchronous rectification, ST offers dedicated SR controllers like STSR3.
How does soft recovery (Sfactor = 0.3) impact EMI in DC/DC layouts?
A soft recovery factor of 0.3 means the diode's reverse current decays gradually rather than abruptly, reducing di/dt-induced voltage spikes and high-frequency ringing on switching nodes. This directly lowers conducted EMI and eases compliance with EN55032 Class B limits in dense PCB layouts.
Can this diode replace a standard FRD in an existing 100 kHz SMPS design?
Yes-its 27 ns trr and low Qrr make it suitable for 100 kHz designs, but verify thermal performance: its lower VF reduces conduction loss, while faster recovery may require slight snubber adjustment to manage reduced ringing amplitude and frequency shift.
