Product details
Overview
STTH2002G-TR from STMicroelectronics is an ultrafast recovery silicon rectifier diode in D²PAK (TO-263) package, rated for 200 V repetitive peak reverse voltage and 20 A average forward current at TC = 120 °C. It delivers 16 ns typical reverse recovery time, 0.86 V typical forward voltage at 20 A and 150 °C, and operates up to 175 °C junction temperature. It is designed for high-frequency DC–DC converters and switch-mode power supplies requiring low conduction and switching losses.
For engineers reviewing the STTH2002G-TR datasheet, STTH2002G-TR pinout, STTH2002G-TR application, or STTH2002G-TR equivalent, key selection criteria include its 2.4 °C/W junction-to-case thermal resistance, insulated variant availability (STTH2002DI), and verified performance under dIF/dt = −100 A/µs with 8–10 A peak reverse recovery current at 125 °C.
Technical Context
This single-anode, single-cathode ultrafast diode uses optimized lifetime control to achieve sub-20 ns trr while maintaining low VF and high Tj capability. Its dynamic behavior is characterized under controlled dIF/dt conditions (−50 to −200 A/µs) and VR = 30–160 V, with Qrr varying predictably with dIF/dt and junction temperature.
The device's thermal design relies on direct case conduction via the D²PAK exposed copper tab, supporting PCB copper area optimization per Figure 10. Its ECOPACK®2 compliance confirms halogen-free, RoHS-compliant construction without compromising insulation integrity or thermal performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands 200 V repetitive reverse voltage without breakdown; suitable for 12–48 V output SMPS with margin. |
| IF(AV) | 20 A at TC = 120 °C - Sustains continuous 20 A forward current when mounted on heatsink maintaining case at 120 °C. |
| trr (typ.) | 16 ns - Enables operation >500 kHz switching frequencies with minimal switching loss in hard-switched topologies. |
| VF (typ.) | 0.86 V at IF = 20 A, Tj = 150 °C - Reduces conduction loss to ~17.2 W (P ≈ 0.75×IF(AV) + 0.01×IF²(RMS)) in high-temp operation. |
| Rth(j-c) | 2.4 °C/W - Allows 79 °C temperature rise across junction-to-case for 33 W dissipation, enabling compact thermal design. |
| Tj (max.) | 175 °C - Supports operation in sealed industrial enclosures or high-ambient environments without derating below 125 °C. |
| IRM (typ.) | 9 A at IF = 20 A, dIF/dt = −100 A/µs, VR = 160 V, Tj = 125 °C - Defines EMI and snubber sizing requirements during turn-off. |
Pinout & Package
STTH2002G-TR is housed in a surface-mount D²PAK (TO-263) package with an exposed copper drain pad (cathode) and two signal leads: anode (pin 1) and cathode (pin 2). The package features a single-row 3-pin configuration (A-K-tab), where the large metal tab is electrically connected to the cathode and serves as the primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to input/high-side node; must be routed with low-inductance trace to minimize voltage overshoot during recovery. |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Electrically tied to exposed tab; requires full-solder coverage to PCB copper pour for optimal thermal transfer and EMI control. |
| Tab (Cathode) | Thermal and electrical cathode connection | Provides low-impedance thermal path (2.4 °C/W) and must be isolated from chassis ground unless circuit topology permits common-cathode mounting. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (trr ≤ 20 ns) | Enables >500 kHz operation in LLC resonant and phase-shifted full-bridge converters without excessive diode switching loss. |
| Low VF at high Tj (0.86 V @ 150 °C) | Reduces conduction loss by ~15% compared to standard fast diodes at elevated temperatures, improving system efficiency stability. |
| High Tj rating (175 °C) | Eliminates need for additional thermal derating in automotive under-hood or industrial motor drive applications. |
| ECOPACK®2 compliance | Confirms halogen-free, lead-free, RoHS-compliant construction with UL94 V0 epoxy - meets IPC-J-STD-020 moisture sensitivity level 1. |
| Insulated variant available (STTH2002DI) | Supports direct mounting to heatsinks without isolation hardware; 2500 VRMS insulation enables use in floating-ground topologies. |
Applications
| Server PSU Rectification | Industrial DC–DC Converter |
|---|---|
|

Use Scenario: Output rectification in 24 V input, 5 V/30 A isolated DC–DC module for PLC I/O modules. IC Role / Device Role / Timing Role: High-frequency rectifier in asymmetrical half-bridge topology operating at 300 kHz. Use Value: 2.4 °C/W Rth(j-c) allows direct thermal coupling to 25 cm² internal copper plane, eliminating external heatsink. |
| Solar Microinverter Freewheeling | Automotive On-Board Charger (OBC) |
|
Use Scenario: Freewheeling path in H-bridge inverter stage of 300 W solar microinverter. IC Role / Device Role / Timing Role: Clamp diode handling reactive current during zero-crossing commutation in unidirectional energy flow. Use Value: 175 °C Tj rating supports operation inside sealed aluminum enclosure with ambient up to 105 °C. |

IC Role / Device Role / Timing Role: Low-loss freewheeling diode in interleaved totem-pole PFC and secondary-side synchronous rectification. Use Value: 0.86 V VF at 150 °C ensures stable conduction loss across full vehicle thermal range (−40 °C to +125 °C ambient). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1202S | 12 A IF(AV), same VRRM (200 V), 15 ns trr, DPAK package (smaller thermal mass) | Limited to lower-power (<300 W) adapters; lacks D²PAK thermal robustness for sustained 20 A loads | Select when board space is constrained and peak load is <15 A RMS; verify Rth(j-c) = 3.5 °C/W suffices. |
| IXYS MBR20200CT | 20 A IF(AV), 200 V VRRM, Schottky architecture, VF ≈ 0.85 V but Tj(max) = 150 °C, no trr (no recovery charge) | Not usable above 150 °C ambient; unsuitable for high-dV/dt noise-sensitive environments due to higher capacitance | Prefer in low-temp, high-efficiency designs where zero-recovery EMI is critical; avoid in industrial enclosures >100 °C. |
Compared with STTH1202S and MBR20200CT, STTH2002G-TR uniquely balances 20 A current handling, 175 °C operation, and 16 ns trr in D²PAK - making it optimal for thermally demanding, high-frequency industrial and automotive power stages where reliability trumps marginal VF reduction.

FAQ
What is the maximum recommended soldering temperature profile for STTH2002G-TR?
The D²PAK package is rated for IPC-J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles. Peak temperature must not exceed 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. Preheat (150–200 °C) duration should be 60–120 seconds to ensure uniform heating of the large copper tab.
Can STTH2002G-TR replace STTH2002D in existing TO-220AC-based designs?
No direct drop-in replacement is possible due to package differences: STTH2002G-TR is surface-mount D²PAK (TO-263), while STTH2002D is through-hole TO-220AC. Pad layout, thermal interface, and mechanical mounting differ significantly. A redesign of footprint, stencil, and heatsink interface is required to migrate.
How does the 2500 VRMS insulation rating apply to STTH2002G-TR?
STTH2002G-TR itself has no insulation rating - that specification applies only to the insulated TO-220AC variant (STTH2002DI). The D²PAK version (STTH2002G-TR) has no internal isolation barrier; its creepage/clearance depends entirely on PCB layout and conformal coating. For insulated mounting, use STTH2002DI or add external isolating hardware.
Is STTH2002G-TR suitable for bidirectional current applications like regenerative braking circuits?
No. STTH2002G-TR is a unidirectional ultrafast rectifier optimized for forward conduction and fast reverse recovery. It lacks symmetrical reverse conduction capability or controlled reverse recovery characteristics required for true bidirectional switching. Use actively controlled MOSFETs or dedicated bidirectional switches instead.
