Product details
Overview
STTH10R04FP 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 operates up to 175 °C junction temperature.
For engineers reviewing the STTH10R04FP datasheet, STTH10R04FP pinout, STTH10R04FP application, or STTH10R04FP equivalent, key selection criteria include conduction loss modeling (P = 1.05×IF(AV) + 0.03×IF²(RMS)), softness factor (S ≥ 0.3), thermal resistance (Rth(j-c) = 3.5 °C/W), and surge capability (IFS M = 100 A, tp = 10 ms).
Technical Context
This device implements a planar epitaxial ultrafast diode structure optimized for low Qrr and controlled soft recovery-critical for minimizing switching losses and EMI in high-frequency PDP energy recovery blocks. Its 1.15 V typical forward voltage at 125 °C and 10 A ensures efficient clamping with minimal conduction loss.
The D²PAK package enables direct thermal coupling to heatsinks via the exposed cathode tab, supporting continuous operation at Tj = 175 °C. Dynamic parameters-including trr = 15 ns (typ.), tfr = 140 ns (max), and Sfactor = 0.3 (min)-are characterized under standardized dIF/dt conditions (200 A/µs) and VR = 200 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage for reliable clamping in 300–400 V PDP bus applications |
| IF(peak) | 10 A - peak forward current rating defining safe single-pulse clamping energy handling |
| trr (typ.) | 15 ns - ultrafast reverse recovery enabling >1 MHz switching in resonant recovery topologies |
| VF (typ.) | 1.15 V @ 125 °C, 10 A - low forward drop directly reducing conduction loss and thermal stress |
| Rth(j-c) | 3.5 °C/W - thermal resistance from junction to case, enabling high-power dissipation with minimal ΔT |
| Sfactor | ≥ 0.3 - soft recovery behavior limiting voltage overshoot and EMI during turn-off |
| IFS M | 100 A @ tp = 10 ms - non-repetitive surge rating supporting transient energy absorption in PDP sustain cycles |
Pinout & Package
D²PAK (TO-263) package with isolated mounting tab (cathode), standard 3-pin layout: Anode (pin 1), Cathode (tab + pin 2), and NC (pin 3). Thermal path optimized through copper-tab conduction; UL94 V0 epoxy molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode (Tab + Pin 2) | Forward current exit / heat sink interface | Electrically and thermally coupled to PCB copper pour or heatsink; primary thermal path |
| NC (Pin 3) | No internal connection | Unused terminal; electrically isolated; no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr = 15 ns (typ.) enables high-frequency (>500 kHz) clamping without excessive switching loss |
| Soft recovery characteristic | Sfactor ≥ 0.3 reduces voltage ringing and EMI during turn-off in inductive PDP circuits |
| High junction temperature rating | Tj(max) = 175 °C supports operation in thermally constrained PDP chassis environments |
| Low leakage current | IR ≤ 100 µA @ 125 °C ensures stable blocking performance over lifetime in high-temp operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH12R06D | 600 V VRRM, 12 A IF(peak), 25 ns trr (typ.), Rth(j-c) = 3.0 °C/W | Higher voltage margin for 600 V bus systems; slower recovery increases switching loss at >300 kHz | Select when higher reverse voltage headroom is required and dIF/dt < 300 A/µs |
| IXYS MUR1040CT | 400 V VRRM, 10 A IF(peak), 35 ns trr (typ.), TO-220AC package, Rth(j-c) = 4.0 °C/W | Larger thermal resistance and slower recovery limit use in compact, high-frequency PDP modules | Prefer for cost-sensitive industrial supplies where footprint and EMI are less critical |
Compared with STTH10R04FP, STTH12R06D trades speed for voltage margin and thermal efficiency, while MUR1040CT sacrifices recovery performance and thermal capability for legacy package compatibility and lower unit cost.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The STTH10R04FP is rated for continuous operation up to 175 °C junction temperature, verified per absolute maximum ratings in Table 2 of the official datasheet (DocID13971 Rev 2). This allows direct mounting on heatsinks in thermally dense PDP chassis without derating below full 10 A peak current.
Does the NC pin require PCB routing or grounding?
No - Pin 3 is internally unconnected (NC) and electrically isolated. It must not be soldered or routed on the PCB. The D²PAK mechanical drawing (Figure 13) confirms no internal bond wire or die connection to this terminal; routing it may compromise thermal integrity or cause unintended parasitic coupling.
How is conduction loss calculated for thermal design?
Conduction loss is calculated using the manufacturer-provided equation: P = 1.05 × IF(AV) + 0.03 × IF²(RMS), where IF(AV) is average forward current and IF(RMS) is RMS forward current. This empirical model accounts for both linear and quadratic resistive components across temperature and current ranges.
Is the D²PAK package lead-free and RoHS compliant?
Yes - the STTH10R04FP is ECOPACK®2 compliant, meeting RoHS Directive 2011/65/EU and halogen-free requirements. The epoxy molding compound is UL94 V0 rated, and all plating meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) specifications.
