Product details
Overview
STPS16170CG-TR from STMicroelectronics is a dual-center-tab high-voltage Schottky rectifier in D²PAK package, rated for 170 V repetitive peak reverse voltage and 2 × 8 A average forward current per diode at Tc = 150 °C. It features low forward voltage drop (0.70 V typ. at 8 A, 125 °C), 175 °C maximum junction temperature, avalanche-rated capability (335 W, 10 µs), and ECOPACK®2 compliance. It is engineered for high-frequency switched-mode power supplies requiring efficient conduction and thermal robustness.
For engineers reviewing the STPS16170CG-TR datasheet, STPS16170CG-TR pinout, STPS16170CG-TR application, or STPS16170CG-TR equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (1.8 °C/W total), leakage current limits (15 mA max at 125 °C), avalanche energy rating, and D²PAK mounting requirements for high-power dissipation.
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode junctions sharing a common center tab for mechanical and thermal anchoring. Each diode supports simultaneous operation with coupled thermal dynamics: junction temperature rise depends on both its own power dissipation and cross-heating from the adjacent diode via Rth(c) = 0.6 °C/W coupling resistance.
Conduction loss modeling uses P = 0.64 × IF(AV) + 0.014 × IF²(RMS), reflecting non-linear VF behavior across temperature and current. Avalanche capability is validated per AN1768/AN2025 under 10 µs pulses at Tj = 125 °C, enabling use in clamping or inductive switching protection without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 170 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in boost/flyback output stages. |
| IF(AV) per diode | 8 A at Tc = 150 °C - Continuous DC current handling per diode with heatsink; total device rating is 16 A when both diodes are used. |
| VF (typ) | 0.70 V at IF = 8 A, Tj = 125 °C - Low forward drop enables <1.12 W conduction loss per diode at rated current, reducing thermal load. |
| IR (max) | 15 mA at VR = 170 V, Tj = 125 °C - Controlled leakage ensures minimal standby loss in high-efficiency SMPS designs. |
| Tj(max) | 175 °C - Enables operation in thermally constrained environments such as enclosed industrial PSUs or automotive under-hood converters. |
| Rth(j-c) total | 1.8 °C/W - Combined junction-to-case thermal resistance for both diodes; critical for heatsink sizing when using shared thermal pad. |
| PARM | 335 W at tp = 10 µs, Tj = 125 °C - Avalanche pulse power rating supports transient overvoltage suppression without failure. |
Pinout & Package
The STPS16170CG-TR is housed in a surface-mount D²PAK (TO-263) package with three terminals: two anodes (A1, A2) and one common cathode (K) connected to the large exposed copper tab. The center tab serves as the cathode and primary thermal path to the PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input terminal for first rectification path; electrically isolated from A2 but thermally coupled via shared case. |
| A2 | Anode of Diode 2 | Input terminal for second independent rectification path; enables dual-output or interleaved converter topologies. |
| K (Tab) | Common Cathode | Output node for both diodes; must be soldered to ≥200 mm² copper area for Rth(j-a) ≤ 15 °C/W per Figure 9. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration with shared cathode tab | Enables compact dual-output or phase-interleaved SMPS designs without discrete cathode wiring or thermal mismatch. |
| Avalanche energy rating (335 W, 10 µs) | Eliminates need for external TVS or RC snubbers in flyback clamp circuits, reducing BOM count and board space. |
| Low VF (0.70 V typ. @ 8 A, 125 °C) | Reduces conduction losses by ~25% versus standard 1N5822-class Schottkys, improving efficiency in 12–48 V output rails. |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements without compromising thermal performance; suitable for industrial and telecom equipment. |
| Junction temperature derating support | Specified dPtot/dTj < 1/Rth(j-a) condition prevents thermal runaway when mounted on properly sized copper areas. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS16170CB-TR | DPAK package (0.32 g), higher Rth(j-c) = 3 °C/W per diode, lower IF(AV) = 8 A total (not per diode). | Suitable only for lower-power (<100 W) or space-constrained designs where thermal mass is limited. | Select when board area is critical and thermal budget allows higher junction rise; not interchangeable in high-current layouts. |
| Vishay VS-16CTQ170PBF | Single-diode TO-220AB package, same 170 V/16 A rating but no dual-anode isolation or shared cathode tab. | Requires two devices and separate cathode routing; lacks integrated thermal coupling for dual-channel control. | Choose only if discrete layout and manual thermal management are acceptable; inferior integration for multi-rail systems. |
Compared with STPS16170CB-TR and VS-16CTQ170PBF, the STPS16170CG-TR uniquely delivers dual-anode isolation with unified cathode thermal anchoring in D²PAK-enabling higher power density, simplified PCB layout, and superior thermal coupling for balanced current sharing in interleaved converters.

FAQ
What is the maximum continuous forward current per diode for STPS16170CG-TR?
The STPS16170CG-TR supports 8 A average forward current per diode at case temperature Tc = 150 °C, with total device rating of 16 A when both diodes operate simultaneously. Derating applies above 150 °C case temperature per Figure 2, and thermal design must account for inter-diode coupling via Rth(c) = 0.6 °C/W.
Does STPS16170CG-TR require a heatsink for operation at full rated current?
Yes - the D²PAK package requires connection to ≥200 mm² of 2-oz copper on the PCB to achieve Rth(j-a) ≤ 15 °C/W (per Figure 9). Without adequate copper area, junction temperature will exceed 175 °C at full load; no external heatsink is needed if PCB copper meets minimum thermal pad requirements.
How is avalanche capability tested and validated for this part?
Avalanche capability is validated per ST application notes AN1768 and AN2025 using 10 µs unidirectional pulses at Tj = 125 °C, measuring PARM = 335 W. Testing confirms single-pulse survivability without parameter shift; repeated avalanche events require energy summation within safe operating area limits defined in the datasheet.
Can STPS16170CG-TR replace STPS16170CR in an existing I²PAK footprint?
No - STPS16170CG-TR uses D²PAK (TO-263) while STPS16170CR uses I²PAK (TO-220AC variant). Footprint dimensions differ significantly: D²PAK has 10.0–10.55 mm E width and 15–15.85 mm H height, whereas I²PAK measures 10–10.4 mm E and 13–14 mm L. Mechanical and thermal rework would be required for substitution.
