Product details
Overview
STTH10R04B-TR from STMicroelectronics is an ultrafast recovery power rectifier in D²PAK package, rated for 400 V repetitive peak reverse voltage and 10 A peak forward current, with typical reverse recovery time of 15 ns and forward voltage drop of 1.15 V at 125 °C. It serves as a clamping diode in plasma display panel (PDP) energy recovery circuits, delivering low conduction and switching losses under high dI/dt conditions.
For engineers reviewing the STTH10R04B-TR datasheet, STTH10R04B-TR pinout, STTH10R04B-TR application, or STTH10R04B-TR equivalent, key selection criteria include ultrafast trr (15 ns typ.), high Tj max (175 °C), low leakage (<10 µA at 25 °C), softness factor (0.3 typ.), and thermal resistance (3.5 °C/W junction-to-case).
Technical Context
This device employs a planar epitaxial silicon structure optimized for ultrafast recovery with controlled minority-carrier lifetime, enabling low Qrr and soft reverse recovery (Sfactor = 0.3). Its dynamic performance is characterized under standardized test conditions: IF = 0.5 A, Irr = 0.25 A, IR = 1 A at 25 °C for trr measurement.
The rectifier operates with a maximum junction temperature of 175 °C and exhibits stable VF across temperature-1.15 V (typ.) at 125 °C/10 A-and maintains low IR (<100 µA at 125 °C), supporting reliable operation in high-temperature PDP energy recovery blocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands repetitive reverse voltage up to 400 V without breakdown in clamping applications. |
| IF(peak) | 10 A - Supports peak forward current required during PDP energy recovery pulses. |
| trr (typ.) | 15 ns - Enables minimal switching loss and EMI in high-frequency energy recycling circuits. |
| VF (typ.) | 1.15 V at 125 °C/10 A - Low conduction loss reduces thermal stress in high-duty-cycle clamping. |
| Rth(j-c) | 3.5 °C/W - Efficient heat transfer to heatsink via D²PAK metal tab, critical for sustained 175 °C operation. |
| Sfactor | 0.3 - Soft recovery limits voltage overshoot and ringing during turn-off in inductive energy recovery paths. |
| Tj (max) | 175 °C - Allows operation in thermally demanding PDP backlight and sustain driver stages. |
Pinout & Package
D²PAK (TO-263) package with isolated metal tab for thermal conduction and electrical isolation of cathode. Three terminals: Anode (pin 1), Cathode (tab), and NC (pin 2, not connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to energy storage capacitor or inductor node in recovery loop; must handle 100 A surge. |
| Cathode (Tab) | Forward current exit / reverse blocking terminal | Mounted directly to heatsink; electrically isolated but thermally coupled; carries full load current. |
| NC (Pin 2) | No connection | Internal die bond pad left unconnected; no circuit function; must remain floating. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 15 ns typical trr enables >1 MHz switching in resonant energy recovery topologies. |
| High surge capability | 100 A non-repetitive surge (tp = 10 ms) withstands PDP sustain pulse transients. |
| Low leakage current | <10 µA at 25 °C ensures minimal standby loss in high-impedance clamp nodes. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy meets stringent environmental requirements for consumer displays. |
| High junction temperature rating | 175 °C max Tj supports compact thermal design in space-constrained PDP module layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF-TR | D²PAK package with insulated tab; Rth(j-c) = 3.5 °C/W same; identical electrical specs. | Required where cathode isolation from heatsink is mandatory (e.g., floating ground systems). | Select when system-level isolation > thermal optimization is prioritized. |
| IXYS MUR1040CT | TO-220AB package; trr = 35 ns (slower); VF = 1.3 V (higher); IFSM = 120 A (higher). | Better surge margin but higher switching loss; unsuitable for >500 kHz PDP recovery. | Choose only if board layout constraints prohibit D²PAK or if surge robustness outweighs efficiency. |
Compared with STTH10R04DJF-TR, the STTH10R04B-TR offers identical performance in non-isolated thermal mounting; versus MUR1040CT, it delivers 57% faster recovery and 13% lower VF at 125 °C-critical for high-frequency, thermally constrained PDP designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device has a maximum junction temperature of 175 °C and a junction-to-case thermal resistance of 3.5 °C/W. Assuming worst-case ambient and heatsink conditions, the case temperature must remain ≤140 °C to maintain safe margin-verified via thermal simulation using the provided Zth(j-c) curve and actual power dissipation (P = 1.05 × IF(AV) + 0.03 × IF²(RMS)).
Is the STTH10R04B-TR pin-compatible with STTH10R04G-TR?
Yes-both share identical D²PAK mechanical outline, pin 1 anode / pin 2 NC / cathode tab configuration, and identical thermal and electrical specifications. The "-B" and "-G" suffixes denote minor internal process revisions; no layout or schematic changes are required for substitution.
Does this diode require a snubber circuit in PDP energy recovery applications?
No snubber is required due to its soft recovery characteristic (Sfactor = 0.3) and low Qrr (25 nC typ.), which suppress voltage overshoot and ringing. Application notes confirm stable operation without external RC networks when used with matched gate drivers and PCB layout minimizing loop inductance.
Can STTH10R04B-TR be used in automotive under-hood environments?
It is not qualified to AEC-Q101 and lacks automotive-specific qualification testing (e.g., HTOL, temperature cycling). While its 175 °C Tj rating exceeds typical under-hood requirements, ST does not guarantee reliability or provide PPAP documentation for automotive use-industrial and display applications remain its validated scope.
