Product details
Overview
STPS1660 from Diodes Incorporated is a 16A dual common-cathode super-fast rectifier diode rated for 600V peak reverse voltage, with 1.5V max forward voltage at 8A/25°C and 50ns reverse recovery time, designed for high-frequency DC-DC converters and switched-mode power supplies.
For engineers reviewing the STPS1660 datasheet, STPS1660 pinout, STPS1660 application, or STPS1660 equivalent, key selection criteria include its ITO220AB package thermal resistance (RθJC = 3°C/W), low 10µA reverse leakage at 600V/25°C, and 100A non-repetitive surge rating-critical for PFC and output rectification in industrial and telecom power systems.
Technical Context
The STPS1660 integrates two independent 8A-rated super-fast rectifier dies in a single ITO220AB package, sharing a common cathode terminal. Its silicon die uses glass passivation for reliability under thermal cycling and high-voltage stress.
Designed for hard-switched topologies, it achieves 50ns tRR with controlled minority-carrier lifetime, enabling operation up to several hundred kHz without excessive switching loss. The 3°C/W junction-to-case thermal resistance supports direct mounting to heatsinks in compact 16A-output designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Sustains peak reverse voltage in boost PFC and flyback primary-side rectification |
| IO (per leg) | 8 A @ TC = +80°C - Continuous current capability per anode leg under real heatsink conditions |
| VF max | 1.50 V @ 8A, 25°C - Limits conduction loss to ≤12W per leg at full load in 12V/100A systems |
| tRR | 50 ns - Enables efficient operation in 200–500 kHz SMPS without snubber-induced losses |
| IFSM | 100 A (8.3 ms half-sine) - Withstands inrush and transient surges in server PSU and industrial AC-DC front-ends |
| RθJC | 3 °C/W - Allows 40°C temperature rise at 16A total dissipation with modest heatsinking |
| IR max | 10 µA @ 600V, 25°C - Minimizes standby power loss in high-voltage hold-up circuits |
Pinout & Package
Package: ITO220AB (Type WX2), molded plastic with matte tin-plated leads, UL 94V-0 rated, 1.558g weight. Mounting via center tab (cathode) to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifier leg | Accepts AC or switched input; electrically isolated from Anode 2 and case |
| Anode 2 (Lead 2) | Input terminal for second rectifier leg | Enables dual-output or interleaved rectification; shares cathode with Anode 1 |
| Cathode (Tab) | Common output node and thermal path | Must be electrically insulated from chassis if floating output; primary heat extraction surface |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast switching (tRR = 50 ns) | Reduces turn-off energy loss by >40% vs. standard fast rectifiers in 300 kHz converters |
| Glass passivated die | Prevents moisture ingress and metallization corrosion during reflow and long-term operation |
| 600V VRRM rating | Supports 400V DC bus designs with 50% safety margin for line transients and ringing |
| Low RθJC (3°C/W) | Permits 16A total output in space-constrained 1U server PSUs without forced air |
| RoHS 3 & "Green" compliant | Meets Br+Cl <1500 ppm and Sb <1000 ppm for automotive and EU industrial compliance |
Applications
| Server Power Supply Rectification | Industrial DC-DC Converter Output |
|---|---|
Use Scenario: 12V/100A output stage in 1U redundant AC-DC power supply. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacement operating at 250 kHz with shared cathode return. Use Value: 1.5V VF reduces conduction loss by 1.2W per leg versus 1.7V alternatives, lowering heatsink mass by 35%. |
Use Scenario: 48V-to-12V isolated buck-derived converter in PLC backplane power. IC Role / Device Role / Timing Role: Secondary-side common-cathode rectifier handling bidirectional current in active clamp forward topology. Use Value: 50ns tRR prevents reverse recovery shoot-through during zero-voltage switching transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast dual common-cathode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | 16A, 600V, tRR = 65 ns, VF = 1.7V @ 8A - higher conduction and switching loss | Higher thermal rise in compact enclosures; requires larger heatsink area | Preferred where cost sensitivity outweighs efficiency targets in non-telecom industrial use |
| VS-16CTQ060 | 16A, 60V, Schottky architecture - no reverse recovery but limited to ≤60V applications | Not usable in 400V+ DC bus systems; unsuitable for PFC or telecom rectification | Select only for low-voltage (<48V) high-efficiency DC-DC where VRRM margin is irrelevant |
Compared with STTH1606D, STPS1660 delivers 15% lower conduction loss and 23% faster recovery; versus VS-16CTQ060, it trades Schottky efficiency for 10× higher voltage capability-making it the sole viable option for 400–600V bus rectification.

FAQ
Is STPS1660 suitable for synchronous rectification topologies?
No. STPS1660 is a passive super-fast diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively driven. It serves as a freewheeling or output rectifier in non-synchronous topologies like standard forward, flyback, or boost converters where simplicity and reliability are prioritized over peak efficiency.
What is the maximum recommended PCB copper area for thermal relief on the cathode tab?
For optimal thermal performance, Diodes recommends ≥400 mm² of 2-oz copper connected directly to the cathode tab, with thermal vias (≥8 × 0.3mm diameter) to an internal ground plane or external heatsink. This achieves near-datasheet RθJC = 3°C/W in free-air testing per JESD-51-2.
Does STPS1660 meet AEC-Q101 for automotive use?
No. STPS1660 is not AEC-Q101 qualified. While Diodes offers AEC-Q101 versions in the same ITO220AB package (e.g., STPS1660H), this specific part number is intended for industrial and computing applications. Automotive designs require explicit qualification documentation and PPAP support.
Can STPS1660 be paralleled for higher current capacity?
Yes, but only with matched VF devices and symmetrical layout. Parallel operation requires individual current-sharing resistors (0.01Ω, 1% tolerance) in series with each anode lead to mitigate thermal runaway. Derate total current by 20% versus sum of individual ratings due to thermal coupling in shared heatsink mounting.
