Product details
Overview
STTH10R04G-TR from STMicroelectronics is an ultrafast recovery power rectifier in D²PAK package, designed for clamping in plasma display panel (PDP) energy recovery circuits. It delivers 10 A peak forward current, 400 V repetitive reverse voltage, 15 ns typical reverse recovery time, and 1.15 V typical forward voltage at 125 °C - enabling high-efficiency switching in high-frequency PDP sustain stages.
For engineers reviewing the STTH10R04G-TR datasheet, STTH10R04G-TR pinout, STTH10R04G-TR application, or STTH10R04G-TR equivalent, key selection criteria include ultrafast trr (15 ns typ.), low VF (1.15 V @ 125 °C), high Tj (175 °C), surge capability (100 A IFSM), and thermal resistance (3.5 °C/W j-c).
Technical Context
This device operates as a unidirectional, silicon-based power rectifier optimized for fast commutation in resonant energy recovery topologies. Its soft recovery behavior (Sfactor ≥ 0.3) minimizes EMI during turn-off, while the low leakage current (<10 µA @ 25 °C) supports stable blocking in high-voltage hold phases.
The D²PAK package enables direct thermal coupling to heatsinks via its exposed cathode tab, supporting continuous operation at junction temperatures up to 175 °C. Dynamic performance is characterized under standardized conditions: trr measured at IF = 0.5 A, Irr = 0.25 A, IR = 1 A; VFP and tfr tested at dIF/dt = 100 A/µs with IF = 10 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage, suitable for 300–400 V DC bus applications |
| IF(peak) | 10 A - peak forward current rating at TC = 135 °C, δ = 0.5 square wave |
| trr (typ.) | 15 ns - ultrafast reverse recovery time reduces switching losses in >100 kHz PDP sustain circuits |
| VF (typ.) | 1.15 V @ Tj = 125 °C, IF = 10 A - low conduction loss improves system efficiency at elevated temperature |
| Rth(j-c) | 3.5 °C/W - thermal resistance from junction to case enables effective heatsink cooling in compact designs |
| Tj (max) | 175 °C - high junction temperature rating supports reliable operation in thermally constrained PDP modules |
| IFS M | 100 A - non-repetitive surge current (tp = 10 ms, sinusoidal) withstands transient overloads |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated mounting tab (cathode), featuring three terminals: Anode (pin 1), Cathode (tab), and NC (pin 2). The exposed copper tab serves as the cathode connection and primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current input | Connects to high-side switching node; carries full load current during conduction phase |
| Cathode (Tab) | Forward current output / heat sink interface | Electrically and thermally connects to PCB copper pour or heatsink; must be soldered for thermal and electrical integrity |
| NC (Pin 2) | No internal connection | Unused terminal; electrically isolated - no routing or grounding required |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 15 ns typical trr ensures minimal switching loss and EMI in high-frequency (>100 kHz) PDP sustain circuits |
| Soft recovery behavior | Sfactor ≥ 0.3 suppresses voltage overshoot and ringing during diode turn-off |
| High surge capability | 100 A IFSM withstands repeated energy recovery transients without degradation |
| Low leakage current | <10 µA @ 25 °C VR = VRRM maintains stable blocking in high-impedance hold states |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements for environmentally regulated industrial displays |
Applications
| Plasma Display Panel (PDP) Energy Recovery | Industrial Switch-Mode Power Supplies |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06D-TR | 600 V VRRM, 20 ns trr (typ.), 1.25 V VF @ 125 °C | Higher voltage margin for 450–600 V bus designs; slightly higher conduction loss | Select when system requires >450 V reverse blocking with minimal layout change |
| IXYS MUR1040CT | 400 V VRRM, 35 ns trr (typ.), TO-220AC package, 2.0 V VF @ 125 °C | Slower recovery and higher VF increase switching/conduction losses; through-hole mounting | Use only if D²PAK footprint is unavailable and thermal budget allows higher Rth(j-a) |
Compared with STTH10R04G-TR, the STTH10R06D-TR trades 5 ns slower recovery for +200 V blocking headroom, while the MUR1040CT sacrifices speed and efficiency for legacy through-hole compatibility - making the STTH10R04G-TR optimal for space-constrained, high-frequency PDP and SMPS designs.

FAQ
What is the recommended PCB footprint for STTH10R04G-TR?
The D²PAK footprint must match ST's recommended layout in Figure 14: 8.6–9.35 mm length, 10.0–10.55 mm width, with ≥100 mm² copper pour under the cathode tab. Thermal vias (≥6×0.3 mm) into inner layers are advised to maintain Rth(j-a) ≤ 25 °C/W in standard FR4 boards.
Does STTH10R04G-TR require a heatsink in continuous 10 A operation?
Yes - at 10 A average current and 175 °C max junction temperature, the 3.5 °C/W Rth(j-c) demands active or substantial passive heatsinking. Without external cooling, junction temperature exceeds rating within seconds due to ~11.5 W conduction loss (calculated using P = 1.05 × IF(AV) + 0.03 × IF²(RMS)).
How does soft recovery (Sfactor) benefit EMI performance?
A softness factor ≥ 0.3 ensures gradual current decay during turn-off, reducing di/dt-induced voltage spikes and high-frequency ringing. This directly lowers conducted EMI in PDP sustain drivers, easing compliance with CISPR 22 Class B limits without added RC snubbers.
Can STTH10R04G-TR replace standard FR107 diodes in existing designs?
No - FR107 has 500 ns trr and 1.3 V VF, making it unsuitable for >50 kHz operation. Substituting STTH10R04G-TR requires verifying PCB thermal design (D²PAK vs. DO-41), gate drive timing (due to faster recovery), and snubber re-optimization to avoid oscillation from reduced stored charge.
