Product details
Overview
STPS16170CG 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, with typical forward voltage drop of 0.70 V at 125 °C and 8 A - optimized for high-frequency switched-mode power supplies in industrial AC/DC adapters and server PSUs.
For engineers reviewing the STPS16170CG datasheet, STPS16170CG pinout, STPS16170CG application, or STPS16170CG equivalent, key selection criteria include avalanche-rated 335 W peak power (tp = 10 µs), low 15 µA reverse leakage at 25 °C, 175 °C max junction temperature, and thermal resistance of 1.8 °C/W (total) for dual-diode conduction under heatsink mounting.
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode junctions sharing a common center tab for thermal coupling and mechanical stability. Each diode supports simultaneous operation with validated thermal interaction modeled via Rth(j-c) = 3 °C/W per diode and Rth(c) = 0.6 °C/W coupling term.
It delivers avalanche capability per diode up to 335 W at Tj = 125 °C and tp = 10 µs, with conduction loss approximated by P = 0.64 × IF(AV) + 0.014 × IF²(RMS). Static performance is characterized across -65 to +175 °C storage range and up to 175 °C operating junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 170 V - maximum repetitive reverse blocking voltage per diode; defines usable input voltage headroom in boost PFC or output rectification stages |
| IF(AV) per diode | 8 A at Tc = 150 °C - continuous DC current rating per junction under heatsink-cooled conditions; total device handles 16 A average when both diodes are used |
| VF (Typ) | 0.70 V at Tj = 125 °C, IF = 8 A - low forward drop reduces conduction losses in high-efficiency SMPS designs |
| IR (Max) | 15 mA at Tj = 125 °C, VR = VRRM - controlled leakage enables stable operation in high-temperature environments without thermal runaway risk |
| Rth(j-c) total | 1.8 °C/W - effective thermal resistance from junction to case for combined dual-diode structure; critical for heatsink sizing in compact power modules |
| PARM | 335 W at tp = 10 µs, Tj = 125 °C - specified avalanche energy handling per diode; supports transient surge resilience in unclamped inductive switching |
| Tj(max) | 175 °C - maximum allowable junction temperature; enables operation in thermally constrained enclosures without derating below full current rating |
Pinout & Package
The STPS16170CG is housed in a surface-mount D²PAK (TO-263) package with three terminals: two anodes (A1, A2) and one shared cathode (K) on the center thermal tab. The package features exposed copper thermal pad for direct PCB heatsinking and complies with ECOPACK®2 environmental standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky junction; electrically isolated from A2 but thermally coupled via shared tab |
| A2 | Anode 2 | Input terminal for second Schottky junction; enables dual-output or interleaved rectification topologies |
| K (Tab) | Common Cathode | Output node and primary thermal path; must be soldered to large copper pour for optimal Rth(j-a) management |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | Rated for continuous operation up to 175 °C junction temperature - eliminates need for oversized heatsinks in space-constrained industrial power supplies |
| Low VF / IR trade-off | 0.70 V VF at 125 °C and 8 A with only 15 mA IR at same condition - balances efficiency and leakage-driven thermal rise in high-density converters |
| Avalanche capability | 335 W peak avalanche power per diode (tp = 10 µs) - provides robustness against inductive switching transients without external snubbers |
| Dual-center-tab configuration | Two independent anodes share single cathode tab - simplifies PCB layout for dual-output SMPS and enables thermal coupling for balanced current sharing |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy and lead-free terminations - meets global environmental regulations for industrial and telecom equipment |
Applications

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 |
|---|---|---|---|
| Vishay VS-16CTH17-M3 | Same 170 V VRRM and 2 × 8 A rating, but D²PAK-3L package with 2.2 °C/W Rth(j-c); VF = 0.82 V at 125 °C | Higher VF increases conduction loss by ~17% at 8 A; suitable where thermal margin exists but efficiency is secondary | Select when legacy footprint compatibility with Vishay design is required and 0.12 V higher VF is acceptable |
| ON Semiconductor MUR1620CTG | Ultrafast recovery silicon diode, not Schottky; 200 V VRRM, 2 × 8 A, VF = 1.15 V, no avalanche rating | Lacks avalanche capability and has higher VF; requires snubber circuits and larger heatsinks in high-frequency designs | Only consider for cost-sensitive, lower-frequency (<100 kHz) applications where Schottky advantages are not critical |
Compared with VS-16CTH17-M3 and MUR1620CTG, STPS16170CG uniquely combines 0.70 V VF, 335 W avalanche rating, and 1.8 °C/W thermal resistance - making it optimal for high-efficiency, high-reliability 200–500 kHz SMPS where thermal density and transient robustness are prioritized.

FAQ
What is the maximum continuous forward current per diode for STPS16170CG?
The STPS16170CG 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. This rating assumes proper PCB copper area for thermal dissipation and is validated per Table 2 in the official datasheet (DocID12540 Rev 4).
Does STPS16170CG have avalanche capability, and how is it specified?
Yes - each diode is rated for 335 W repetitive peak avalanche power at Tj = 125 °C and pulse duration tp = 10 µs, as defined in Table 2. This capability is validated per ST application notes AN1768 and AN2025 and enables reliable operation during inductive switching transients without external clamping.
Can STPS16170CG be used in place of a single-diode Schottky like STPS10170CG?
No - STPS16170CG is a dual-diode device with two anodes and one shared cathode, while STPS10170CG is a single-diode D²PAK part. Pinout, thermal coupling, and current-sharing behavior differ fundamentally; substitution requires PCB layout revision and thermal revalidation.
What is the recommended PCB footprint for STPS16170CG's D²PAK package?
The official footprint uses 10.00 × 10.55 mm outline with 8.10–8.90 mm E1 dimension and 4.88–5.28 mm e1 pitch (Table 7, DocID12540 Rev 4). A minimum 25 mm² exposed copper pad under the thermal tab is recommended to achieve Rth(j-a) ≤ 15 °C/W in typical 2-layer board configurations.
