Product details
Overview
STTH1302CG-TR from STMicroelectronics is a dual-center-tap ultrafast recovery rectifier diode in D²PAK package, rated for 200 V repetitive peak reverse voltage, 6.5 A average forward current per diode (13 A device total), and 16 ns typical reverse recovery time. It operates up to 175 °C junction temperature and is optimized for low-loss operation in high-frequency switch-mode power supplies.
For engineers reviewing the STTH1302CG-TR datasheet, STTH1302CG-TR pinout, STTH1302CG-TR application, or STTH1302CG-TR equivalent, key selection criteria include ultrafast trr (16 ns typ.), dual-diode thermal coupling behavior, D²PAK thermal resistance (1.9 °C/W total junction-to-case), and suitability for low-voltage DC–DC inverters and freewheeling paths where conduction and switching losses must be minimized.
Technical Context
This dual-center-tap configuration integrates two independent ultrafast diodes sharing a common cathode terminal (K), enabling synchronous rectification or center-tapped transformer secondary rectification. Each diode exhibits 0.81 V typical forward voltage at 125 °C and 6.5 A, with reverse recovery charge Qrr of ~25 nC (typ.) under IF = 6.5 A, VR = 100 V conditions.
The device uses planar epitaxial silicon technology with soft recovery characteristics, minimizing EMI in high-dI/dt environments (up to 1000 A/µs). Thermal design requires accounting for coupling: ΔTj(diode1) = P₁ × 3 °C/W + P₂ × 0.8 °C/W, due to shared case thermal path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback or forward converter outputs. |
| IF(AV) per diode | 6.5 A - Continuous average forward current rating per diode at TC = 155 °C; determines heatsink sizing for steady-state conduction loss. |
| trr (typ) | 16 ns - Typical reverse recovery time at 25 °C; enables >1 MHz switching in resonant topologies with minimal turn-off loss. |
| VF (typ, 125 °C) | 0.81 V - Forward voltage drop per diode at elevated temperature and 6.5 A; directly impacts conduction loss (P ≈ 0.80×IF(AV) + 0.023×IF²(RMS)). |
| Tj (max) | 175 °C - Maximum junction temperature; allows operation in compact, thermally constrained industrial power modules. |
| Rth(j-c) total | 1.9 °C/W - Total junction-to-case thermal resistance for both diodes active; critical for calculating combined thermal rise under dual-load conditions. |
Pinout & Package
D²PAK (TO-263-3) surface-mount package with exposed copper tab for thermal conduction. Dimensions: 10.55 mm × 9.35 mm × 4.60 mm (L × W × H); weight: 1.38 g; ECOPACK®2 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K (Tab) | Common cathode | Electrically and thermally connected to exposed metal tab; must be soldered to PCB copper pour for thermal management and circuit return path. |
| A1 | Anode 1 | Input terminal for first diode leg; used in center-tapped transformer secondaries or dual-output freewheeling configurations. |
| A2 | Anode 2 | Input terminal for second diode leg; symmetric with A1; enables balanced current sharing when paired with matched magnetics. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 16 ns trr (typ.) enables high-frequency SMPS operation (>500 kHz) with reduced switching loss and EMI vs. standard fast recovery diodes. |
| Dual-center-tap topology | Single-package integration of two matched diodes with shared cathode simplifies layout and improves thermal symmetry in push-pull or half-bridge rectifiers. |
| High surge capability | 70 A non-repetitive surge current (tp = 10 ms) supports robust startup and fault tolerance in industrial power supplies. |
| High-temperature operation | 175 °C max junction temperature allows use in sealed enclosures or high-ambient environments without derating penalties. |
Applications
| Server VRM Rectification | Industrial DC–DC Inverter |
|---|---|
Use Scenario: High-efficiency 12 V → 1.2 V point-of-load conversion in datacenter server voltage regulator modules. IC Role / Device Role / Timing Role: Dual-center-tap freewheeling diode replacing synchronous MOSFETs in cost-sensitive, medium-power VRMs. Use Value: Reduces gate-drive complexity and eliminates shoot-through risk while maintaining <25 ns effective recovery window for 600 kHz operation. | Use Scenario: Low-voltage (24–48 V input), high-current DC–DC conversion in PLC power modules. IC Role / Device Role / Timing Role: Center-tapped secondary rectifier in isolated forward converter delivering 5–12 V @ 10–20 A output. Use Value: Enables compact transformer design with single secondary winding and eliminates need for dual discrete diodes and associated layout asymmetry. |
| Solar Microinverter Freewheeling | Automotive DC Fast Charging Polarity Protection |
Use Scenario: Freewheeling path in interleaved boost stages of residential solar microinverters (200–400 V DC bus). IC Role / Device Role / Timing Role: Ultrafast clamping diode across IGBTs during dead-time commutation. Use Value: 16 ns trr limits voltage overshoot to <10% of bus voltage under 500 A/µs dI/dt, reducing snubber size by 40% vs. 50 ns diodes. | Use Scenario: Reverse polarity protection on 400 V battery input of EV DC fast charging station auxiliary power supply. IC Role / Device Role / Timing Role: Series-connected anode-to-anode (A1–A2) configuration acting as bidirectional blocking element. Use Value: Withstands 200 V reverse bias per diode and handles 70 A surge during hot-plug events without latch-up or thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1202S-TR | Single-diode D²PAK variant (same VRRM, trr, VF), no center-tap; 6.5 A IF(AV) per device. | Requires external dual placement for center-tap function; increases PCB area and thermal mismatch risk. | Select when layout flexibility outweighs integration benefit, or when only one diode leg is used. |
| IXYS MBR20200CT | 200 V, 20 A dual common-cathode Schottky; zero trr but VF = 0.95 V (typ.) at 125 °C and higher leakage (IR = 1 mA @ 125 °C). | Better efficiency below 120 °C; unsuitable above 125 °C due to thermal runaway risk in Schottky structure. | Select for ambient <85 °C applications prioritizing lowest conduction loss over high-temperature reliability. |
Compared with STTH1302CG-TR, STTH1202S-TR sacrifices integration for layout simplicity, while MBR20200CT trades ultrafast recovery for lower VF at the cost of thermal stability-making STTH1302CG-TR optimal for high-temperature, high-dI/dt industrial SMPS where soft recovery and 175 °C operation are mandatory.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF(AV) = 6.5 A per diode at TC = 155 °C. Exceeding this temperature requires linear derating per Figure 5; at TC = 175 °C, IF(AV) drops to ~4.2 A per diode. The 175 °C limit applies to junction temperature only-case temperature must remain ≤155 °C for full rated current.
Can STTH1302CG-TR be used in parallel with another unit for higher current?
No-parallel operation is not recommended. The dual-diode structure shares a single thermal path and cathode node; paralleling units introduces uncontrolled current imbalance due to VF mismatch and thermal coupling effects. For >13 A, select a higher-rated single-device alternative or redesign with interleaved phases.
Is the D²PAK tab electrically isolated from the cathode terminals?
No-the exposed metal tab is internally bonded to the K (cathode) terminal and is not insulated. It must be mounted to a grounded or cathode-referenced copper pour. Use of insulating thermal pads or sil-pad materials will degrade thermal performance and is not supported by ST's recommended footprint.
How does reverse recovery charge (Qrr) vary with temperature and dI/dt?
Qrr increases with junction temperature and dI/dt. At Tj = 125 °C and dI/dt = 1000 A/µs, Qrr reaches ~40 nC (vs. ~25 nC at 25 °C). This rise directly impacts turn-off loss (E = Qrr × VR) and must be included in thermal calculations for high-frequency designs above 300 kHz.
