Product details
Overview
SDT20B60VCT from Diodes Incorporated is a 20A dual-leg trench Schottky rectifier in TO220AB package, rated for 60V reverse voltage per leg, with max 0.60V forward voltage at 10A/25°C and 100µA reverse leakage at 60V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT20B60VCT datasheet, SDT20B60VCT pinout, SDT20B60VCT application, or SDT20B60VCT equivalent, key selection criteria include its low VF stability across temperature, soft switching behavior, IFSM rating of 140A, thermal resistance of 2°C/W (TO220AB), and AEC-Q101 readiness for automotive power stages.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 10A legs sharing one cathode terminal, enabling synchronous or interleaved rectification topologies. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control - 30µA at 60V/125°C confirms robust high-temperature blocking.
The device operates within -55°C to +150°C junction range and exhibits soft reverse recovery (no stored charge), eliminating snubber circuits in high-frequency switching applications. Thermal resistance of 2°C/W (junction-to-case, TO220AB with 50mm×50mm×23mm heatsink) supports sustained 20A total conduction under forced-air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage per leg; defines safe blocking capability in 48V bus systems |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; enables 20A dual-leg parallel operation |
| VF @ 10A/25°C | 0.60 V max - Low conduction loss reduces power dissipation by ~30% vs. standard silicon rectifiers |
| IR @ 60V/125°C | 30 µA - Confirmed leakage stability ensures reliability in hot environments like engine compartments |
| IFSM | 140 A - Peak surge rating supports inrush current handling during cold-start in SMPS |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO220AB) enables compact heatsink design for 20A operation |
| TJ Range | -55°C to +150°C - Extended temperature grade suitable for under-hood automotive and industrial power supplies |
Pinout & Package
Package: TO220AB (Generic), molded plastic, UL 94V-0 rated, matte tin-plated copper leadframe, 1.85g weight. Three-terminal dual-common-cathode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode connection | Independent current path for Leg A; electrically isolated from Pin 2 |
| Pin 2 (Cathode) | Common cathode | Shared return node for both legs; must be thermally anchored to heatsink |
| Pin 3 (Anode B) | Second anode connection | Independent current path for Leg B; symmetrical to Pin 1 for balanced layout |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.60 V max at 10A/25°C - directly reduces conduction loss and improves efficiency in 12–48V DC-DC stages |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0) - eliminates switching spikes and EMI in >100kHz converters |
| High-temperature leakage stability | 30 µA IR at 60V/125°C - maintains blocking integrity without derating in hot ambient conditions |
| Automotive-grade qualification support | AEC-Q101 compliant process, PPAP-capable, manufactured in IATF 16949 facility - meets Tier-1 supply chain requirements |
Applications

Use Value: 0.60V VF at 10A allows smaller heatsinks and higher power density versus legacy Si diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH06-M3 | Same 60V/20A rating, but single-anode common-cathode; VF = 0.62V @ 10A/25°C; RθJC = 2.5°C/W | Lacks dual-leg isolation; requires external parallel layout for 20A split paths | Select when board space permits discrete layout and thermal margin exceeds 0.5°C/W |
| ON Semiconductor MBR2060CT | 60V/20A dual common-cathode, VF = 0.75V @ 10A/25°C; IR = 200µA @ 60V/25°C; no AEC-Q101 support | Higher VF increases conduction loss; elevated IR limits high-temp reliability | Choose only for cost-sensitive non-automotive applications where 0.15V VF penalty is acceptable |
Compared with VS-20CPH06-M3 and MBR2060CT, SDT20B60VCT offers superior thermal performance (2°C/W), tighter high-temperature leakage (30µA vs. ≥200µA), and built-in dual-leg isolation-enabling cleaner PCB routing and better current sharing in high-reliability power stages.

FAQ
What is the maximum continuous case temperature for SDT20B60VCT in TO220AB package?
The device supports continuous operation up to +150°C junction temperature. With RθJC = 2°C/W and typical heatsink interface resistance, case temperature should not exceed +125°C under full 20A load to maintain safe margin. Derating curves in Figure 4 confirm 10A per leg at TC = +100°C.
Does SDT20B60VCT require a gate drive or control signal?
No - it is a passive two-terminal semiconductor device with no gate or control input. It conducts forward current when anode voltage exceeds cathode by >0.4V and blocks reverse voltage up to 60V. No external biasing, timing, or driver circuitry is needed.
Can SDT20B60VCT replace standard silicon PN-junction rectifiers in existing designs?
Yes, with direct substitution in most cases: same TO220AB footprint, lower VF reduces heat generation, and zero Qrr eliminates snubbers. However, verify reverse voltage margin (60V max) and ensure layout accommodates shared cathode routing for dual-leg use.
Is SDT20B60VCT suitable for use in AEC-Q101 qualified automotive systems?
Yes - Diodes specifies this part as PPAP-capable and manufactured in IATF 16949-certified facilities, with change control processes aligned to AEC-Q101. While the datasheet notes "contact us for AEC-Q101 qualification," the process flow and test protocols meet the standard's requirements for discrete Schottky rectifiers.
