Product details
Overview
STPS1620 from Diodes Incorporated is a 16A dual common-cathode super-fast rectifier diode rated for 200V peak reverse voltage, with 1.1V forward voltage at 8A/25°C and 30ns reverse recovery time. It serves as the primary output rectifier in high-frequency DC-DC converters and SMPS secondary-side power conversion stages.
For engineers reviewing the STPS1620 datasheet, STPS1620 pinout, STPS1620 application, or STPS1620 equivalent, key selection criteria include its 125A non-repetitive surge rating, low 10µA reverse leakage at 200V/25°C, thermal resistance of 3°C/W (junction-to-case), and ITO220AB package compatibility with standard heatsink mounting.
Technical Context
This dual-diode configuration operates with shared cathode connection, enabling synchronous rectification or parallel-leg current handling up to 16A total average output. Its super-fast recovery (tRR = 30ns) minimizes switching losses in topologies operating above 100kHz.
The glass-passivated die construction ensures stable performance across -55°C to +150°C junction temperature range, while the 65pF typical junction capacitance supports efficient high-frequency operation without excessive capacitive loading on gate drivers or control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200V reverse voltage without breakdown, suitable for 48V–96V bus-derived SMPS outputs |
| IO (per leg) | 8 A - delivers 8A continuous DC current per anode leg at TC = +105°C, enabling 16A total dual-leg output |
| VF @ 8A/25°C | 1.10 V - low conduction loss reduces heat generation and improves efficiency in high-current secondary-side rectification |
| tRR | 30 ns - enables use in >200kHz switching converters with minimal reverse recovery loss and EMI |
| IFSM | 125 A - withstands short-duration inrush or fault currents without failure, supporting robust system-level surge protection |
| RθJC | 3 °C/W - allows direct mounting to heatsinks for effective thermal management in space-constrained industrial power supplies |
| IR @ 200V/25°C | 10 µA - ultra-low leakage preserves efficiency in standby and light-load conditions, critical for energy-compliant designs |
Pinout & Package
Package: ITO220AB (Type WX2), molded plastic with matte tin-plated leads, UL 94V-0 rated, 1.558g weight. Mounting via tab (cathode) to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode 2 (Lead 2) | Input terminal for second diode leg | Independent 8A path; enables dual-output or interleaved converter configurations |
| Cathode (Tab) | Common output node (electrically connected to both diodes) | Must be mounted to heatsink for thermal and electrical reference; carries full 16A return current |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | 16A, 200V, tRR = 35ns, VF = 1.15V @ 8A - slightly higher VF and slower recovery | Marginally lower efficiency in >150kHz designs; same ITO220AB footprint | Acceptable where 5ns tRR margin is not critical and legacy STMicro design reuse is required |
| DF16S200 | 16A, 200V, tRR = 25ns, VF = 1.05V @ 8A - faster and lower VF, but RθJC = 3.5°C/W | Better high-frequency efficiency but requires larger heatsink area for same thermal rise | Preferred for new designs targeting maximum efficiency at 250–500kHz, if thermal layout permits |
Compared with STTH1602D and DF16S200, STPS1620 offers optimal balance of 30ns recovery, 1.1V VF, and 3°C/W thermal resistance - making it ideal for thermally constrained 100–200kHz industrial and telecom power supplies where heatsink real estate is limited.

FAQ
What is the maximum junction temperature and how does it affect derating?
The STPS1620 has a maximum junction temperature of +150°C. Its average output current must be derated linearly from 8A per leg at +105°C case temperature down to zero at +150°C. This requires thermal design ensuring RθJA remains within limits when mounted on specified 200mm × 200mm × 4.86mm copper heatsink.
Is STPS1620 qualified for automotive applications?
STPS1620 is not AEC-Q101 qualified out-of-the-box. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - customers must contact Diodes directly to request qualified variants such as STPS1620Q or equivalent automotive-grade part numbers.
Can STPS1620 replace a single 16A Schottky diode?
No - STPS1620 is a dual common-cathode diode (two anodes, one shared cathode). It cannot substitute for a single-anode Schottky unless the circuit explicitly uses dual-input rectification. Its pinout and internal structure differ fundamentally from monolithic 16A Schottky devices like SB16200.
What is the significance of the "Green" marking and halogen-free status?
The "Green" designation confirms compliance with Diodes' halogen- and antimony-free standard: <900ppm bromine, <900ppm chlorine (total Br+Cl <1500ppm), and <1000ppm antimony. This meets IPC-1752A material declaration requirements and supports WEEE/RoHS compliance for export to EU, China, and Korea markets.
